IntroductionThe proper functioning of the skin is influenced by a proper diet. The purpose of this study was to determine the effect of selected nutrients on selected skin parameters.MethodsThe study group included 59 women, who were divided into two age groups (under and over 40 years old). A three-day 24-h dietary interview was conducted among the study women and skin parameters were assessed using the Courage + Khazaka method.ResultsThe results showed LA, ALA, Dietary fiber, Na, K, Mg, Zn, Cu, Vitamin E, Thiamine, Riboflavin, Folates, Vitamins B6, B12 and C correlated with skin elasticity. On the other hand, skin elasticity is influenced exclusively by vitamin D acted on skin firmness.ConclusionThe results obtained indicate that a diet rich in appropriate nutrients has a positive effect on the proper maintenance of important skin parameters.

Microfocused Ultrasound in Regenerative Aesthetics: A Narrative Review on Mechanisms of Action and Clinical Outcomes.

Microfocused ultrasound with visualization (MFU-V) is widely used in aesthetic medicine for skin tightening and rejuvenation. However, its role in regenerative aesthetics and its precise mechanism of action are not fully understood. This narrative review aims to contextualize and articulate the mechanism of action of MFU-V, evaluate its role in regenerative aesthetics, and assess its effectiveness based on existing clinical, histological, and skin-mechanical studies. A comprehensive literature search was performed to collect and analyze studies on MFU's biological mechanisms, clinical outcomes, and impact on extracellular matrix (ECM) regeneration. The review integrates findings from clinical trials, histological analyses, and biomechanical assessments to provide a cohesive understanding of MFU-V's role in aesthetic medicine. MFU-V emits focused ultrasound energy that penetrates multiple skin layers and the superficial musculoaponeurotic system, creating localized thermal coagulation points. These points initiate biological responses that recruit fibroblasts and stimulate the production of new collagen and elastin fibers. Enhanced ECM protein synthesis leads to significant improvements in skin biomechanics and quality, reducing skin laxity and enhancing appearance. Clinical studies support these findings, showing improvements in skin firmness and texture following MFU-V treatment. Through analyzing the underlying biological mechanisms and the observable clinical outcomes, this narrative review sets the stage for a comprehensive understanding of the mechanism of action and role of MFU-V in regenerative aesthetics.

Investigating the Skin Health Benefits of Rosa roxburghii, Punica granatum and Rose: A Randomized Single‐Blind Controlled Clinical Trial

ABSTRACTRecent studies underscore the beneficial impacts of oral natural plant extracts on human skin health, though clinical evidence of their efficacy and safety is limited. This study evaluates the skin health effects of a novel oral supplement containing Rosa roxburghii, Punica granatum, and rose extracts (RPR) 0.70 healthy female participants were randomly assigned to either a control group or an RPR group, with the latter ingesting 20 mL of the RPR supplement daily on an empty stomach over 8 weeks. After 8 weeks, the RPR group exhibited significant enhancements (p < 0.001) in skin hydration, glossiness, elasticity, and skin tone, with increases of 69.02%, 30.48%, 25.97%, and 7.52%, respectively. Concurrently, decreases in skin firmness and melanin levels were observed at 21.17% (p = 0.007) and 25.06% (p < 0.001), respectively. Statistical analysis confirmed that these changes were significantly greater than those in the control group. Image analysis indicated no significant changes in mean optical density of hyperpigmented spots within the RPR group (p = 0.367), but a significant reduction in the areas of hyperpigmented spots, under‐eye fine lines, and crow's feet by 41.50%, 37.55%, and 29.36%, respectively (p < 0.001), whereas no significant changes were detected in the control group. Importantly, no adverse effects were observed. These findings suggest that the combined intake of Rosa roxburghii, Punica granatum, and rose extracts can improve skin health, offering a promising natural alternative for dermatological care.

TRATAMENTO DE GORDURA INFRAORBITAL COM ULTRASSOM MICROFOCADO

Aging is a physiological process determined by various intrinsic and extrinsic factors, being a normal and inevitable process. The periorbital region is one of the first to show signs. This aging in the periorbital region is manifested by several anatomical changes that result in dark circles, wrinkles and sagging skin. These changes are influenced by factors such as the loss of adipose tissue volume and reduced collagen production, in addition to the projection of orbital fat and reduced skin elasticity. Given the significant aesthetic impact of these changes, effective treatment of dark circles has become a priority in aesthetic procedures. This study aimed to present and describe a treatment technique and its results in infraorbital pockets, using the non-invasive method of microfocused ultrasound. Through a case report involving a 50-year-old male patient with complaints of persistent dark circles, a treatment protocol was carried out with microfocused ultrasound using 60 shots per infraorbital region in two sessions, with an interval of 3 months. The evaluation of the results included photographic documentation and facial scanning, which showed a significant improvement in skin firmness and a reduction in infraorbital bags. The work concludes that microfocused ultrasound proved to be effective in treating localized fat and repositioning tissues in the dark circles region, promoting facial rejuvenation and representing a less invasive alternative to blepharoplasty. Results may vary depending on age, skin condition and technique used, in which case additional sessions may be necessary.

HArmonyCa™ hybrid filler to restore connective tissue: An Italian real-life retrospective study.

Facial aging and dermal conditions may negatively influence the quality of life, leading patients to seek aesthetic procedures to restore a more satisfying appearance. HArmonyCa™ is a recently developed hybrid filler that combines the actions of the most common dermal fillers, hyaluronic acid (HA) and calcium hydroxylapatite (CaHA). This study investigates the efficacy and safety of HArmonyCa™ in patients affected by chrono- and photoaging and several facial skin conditions. One hundred and twenty-nine patients, affected by chrono- and photoaging, and skin conditions such as oily and acne-prone skin, rosacea, or scarring, were treated with HArmonyCa™. Injections followed the retrograde linear fanning technique. A physicians' consensus identified five optimal entry points. The physician and patients assessed treatment outcomes using the Global Aesthetic Improvement Scale (GAIS) 9 months after treatment (including immediate lift effect, skin firmness, and elasticity), and 3D images were taken for documentation. Adverse events (AEs) were evaluated immediately after the procedure and after 9 months. According to the physician's assessments, all patients displayed an improvement in facial appearance, particularly during movement, with the patients' evaluation showing agreement. Only minor AEs were reporte, which resolved spontaneously. Moreover, HArmonyCa™ treatment proved compatible with different medications and aesthetic procedures. This study shows that one treatment with HArmonyCa™ yields highly satisfactory outcomes in patients affected by skin conditions. For the first time, we show that HArmonyCa™ is a dynamic filler that improves facial laxity during movement. The treatment proved to be safe and fully compatible with other cosmetic procedures and medications.

Strengthening the Skin Barrier by Using a Late Cornified Envelope 6A-Derived Biomimetic Peptide.

Changes in the expression of cornified envelope (CE) components are a hallmark of numerous pathological skin conditions and aging, underlying the importance of this stratum corneum structure in the homeostasis of the epidermal barrier. We performed a detailed characterisation of LCE6A, a member of the Late Cornified Envelope protein family. Immunohistochemical and immunoblot experiments confirmed that LCE6A is expressed late during epidermal differentiation. Crosslinking assays of recombinant LCE6A performed either insitu on human skin sections or invitro demonstrated that LCE6A is indeed a substrate of transglutaminases and crosslinked to CEs. LCE6A-derived peptides containing a glutamine-lysine sequence retained these properties of the full-length protein and reinforced the mechanical resistance of CE submitted to sonication. We designed P26, a LCE6A-derived biomimetic peptide that similarly reinforced CE invitro, and evaluated its protective properties exvivo, on human skin explants, and in two double blind and vehicle-controlled clinical trials. P26 was able to protect the skin from barrier disruption, to limit the damage resulting from a defective barrier, and could improve the signs of aging such as loss of skin firmness and increased skin roughness. Hence, our detailed characterisation of LCE6A as a component of the CE enabled us to develop a LCE6A-derived peptide, biologically active with a new and original mode of action that could be of great interest as a cosmetic ingredient and a pharmacologic agent.

Supramolecular collagen nanoparticles for anti-wrinkle, skin whitening, and moisturizing effects

Collagen-based skincare products can replenish collagen in the skin; however, collagen cannot easily penetrate the dermis, limiting its effectiveness. Therefore, nanomaterials that can enable collagen to effectively penetrate the dermis are urgently needed. This study aimed to determine the potential role of the supramolecular collagen nanoparticles, namely, lactoferrin, recombinant human collagen, and palmitoyl tripeptide-5, in improving the effectiveness of skincare products. Lactoferrin and recombinant collagen served as carriers encapsulating palmitoyl tripeptide-5, with an encapsulation rate of 94.18 %. The supramolecular collagen nanoparticles demonstrated good stability after 1 month. Transdermal efficiency was improved by 69.90 %, allowing the nanoparticles to penetrate deeply into the dermis. Within 28 days of use, the moisture content of the stratum corneum increased by 10.51 %, facial elasticity improved by 8.15 %, skin firmness increased by 12.53 %, facial melanin index decreased by 1.84 %, and individual type angle increased by 19.10 %. Within 14 days, there was a 24.69 % reduction in eye bag wrinkles and a 37.61 % reduction in nasolabial wrinkles. Wrinkle lengths decreased by 10.22 % and 21.57 %, and areas decreased by 34.41 % and 27.92 %, respectively. The supramolecular collagen nanoparticles displayed multiple skincare benefits, including moisturizing, whitening, wrinkle reduction, and firming. In conclusion, the supramolecular collagen nanoparticles are promising candidates for cosmetic products.

A New TGF-β Mimetic, XEP™-716 Miniprotein™, Exhibiting Regenerative Properties Objectivized by Instrumental Evaluation.

Skin aging, which results from intrinsic and extrinsic factors, is characterized by a rough, uneven and wrinkled appearance of the skin at the macroscopic level. At the microscopic level, aging shows lowered keratinocyte turnover, flattened dermal-epidermal junction and reduced collagen fiber density; however, use of skin biopsies to evaluate characteristic properties of these microscopic changes is too limiting for panelists and rarely used. The development of non-invasive techniques is an opportunity to be considered for such evaluations. Our objective was to demonstrate the rejuvenating effects of XEP™-716 Miniprotein™ on skin, a miniprotein having TGF-β beta-like properties, in vitro on normal human fibroblasts and at the clinical level. In vitro, the skin rejuvenation properties of XEP™-716 Miniprotein™ were studied by quantification of well-known dermal components such as collagen type I, hyaluronic acid and elastin. At the clinical level, we used a non-invasive technique, the confocal laser scanning microscopy (CLSM) system, which enabled non-invasive morphological characterization of skin structures (stratum corneum thickness, viable epidermis, full epidermis, dermal-epidermal junction, papillae, dermal collagen density) and high-frequency ultrasonography to quantify the dermal density and thickness, which are useful parameters for quantifying rejuvenating effects on skin. Lastly, a cutometer was used to assess the skin's biomechanical properties, mainly firmness and elasticity. This monocentric double-blind, split-face, randomized, placebo-controlled clinical trial compared the active ingredient XEP™-716 Miniprotein™ in a vehicle on one hemiface versus vehicle alone on the other (placebo) and enrolled panelists aged 40 to 60years old. All measurements were carried out on the malar area before and after 28 and 56days of twice daily application of a cosmetic cream formulation containing either 2.5% or 5% XEP™-716 Miniprotein™. The skin rejuvenating properties were demonstrated by studying dermo-epidermal junction (DEJ) flattening reduction using the measure of two parameters by CLSM: the DEJ length and number of edged papillae. Dermis rejuvenation was assessed by measuring the collagen fiber perimeters (CLSM), dermal density and dermal thickness (ultrasonography). The in vitro results confirmed the ability of XEP™-716 Miniprotein™ to stimulate the key extracellular macromolecules, namely collagen type I, hyaluronic acid and elastin, at a level comparable to that induced by TGF beta growth factor. The clinical data showed that after 28 and 56days of topical XEP™-716 Miniprotein™ application, there was a statistically significant increase of DEJ length, number of edged papillae and collagen fiber perimeters. At the same time point, the B-scan images of facial skin showed a statistically significant increase of dermal density and thickness. These results reveal that the DEJ became more undulated and tightly attached to the dermis, while the papillary dermis was densified, both traits being typical characteristic of younger skin. Rejuvenation was also confirmed by an improvement of skin firmness and elasticity. The in vitro and clinical results presented in this article show that XEP™-716 Miniprotein™ is a potent ingredient to rejuvenate the DEJ and dermis of mature skin.

Ultra-Hypofractionated Whole Breast Radiotherapy with Automated Hybrid-VMAT Technique: A Pilot Study on Safety, Skin Toxicity and Aesthetic Outcomes.

The most prevalent treatment-related side effect related to adjuvant radiotherapy (RT) for breast cancer is acute skin toxicity in the irradiated area. The purpose of this single-institution pilot study is to provide preliminary clinical results on the feasibility and safety of a breast ultra-hypofractionated radiation treatment delivered using an automated hybrid-VMAT technique. Skin damage was assessed both with clinical examination and objectively using a Cutometer equipment. Patients received 26 Gy to the whole breast and 30 Gy to the tumoral bed in 5 fractions using an automated hybrid-VMAT approach with the option for the breath hold technique if necessary. Acute and late toxicities were clinically evaluated at baseline, 1- and 6-months after treatment using the CTC-AE v.5.0 scale. An instrumental evaluation of the skin elasticity was performed using a Cutometer® Dual MP580. Two parameters per patient, R0 (the total skin firmness) and Q1 (the elastic recovery), were registered at the different timelines. From June 2022 to January 2024, 30 patients, stage T1-T2, N0 were enrolled in the study. Four out of 30 (13.3%) patients reported G2 acute skin toxicities. At 6 months, G2 late toxicity was registered in 3 patients (10%). A total of 2160 measures of R0 and Q1 were recorded. At 1 month after treatment, no correlation was found between measured values of R0 and Q1 and clinical evaluation. At 6 months after treatment, clinical late toxicity ≥1 was strongly associated with decreased R0 and Q1 values ≥24% (p = 0.003) and ≥18% (p = 0.022), respectively. Ultra-hypofractionated whole-breast radiotherapy, when supported by advanced treatment techniques, is both feasible and safe. No severe adverse effects were observed at any of the different timeframes. Acute and late skin toxicities were shown to be lower in contrast to data presented in the literature.

Anti-Aging Effects of Low-Molecular-Weight Collagen Peptide Supplementation on Facial Wrinkles and Skin Hydration: Outcomes from a Six-Week Randomized, Double-Blind, Placebo-Controlled Trial

In recent decades, there has been a rising demand for anti-aging interventions aimed at postponing or potentially reversing indicators of skin aging. The use of collagen-based nutraceutical supplements has gained popularity as they have shown promise in enhancing skin health and reducing signs of aging. The aim of this randomized, placebo-controlled, blinded study was to investigate the effects of 2.5 g COLLinstant® LMW, a novel cosmeceutical containing low-molecular-weight (≤1000 Da) collagen peptides, on skin aging and health. The trial was conducted with 80 healthy women aged 30 years and older. They received a daily oral dose of either the food supplement (n = 40) or placebo (n = 40) for six weeks. Skin assessment was performed based on validated objective methods, such as Visioface 1000D (skin wrinkling), cutometry (elasticity and fatigue), and corneometry (skin hydration) at baseline (T0) and at week 6 (T6). After 6 weeks, participants that received collagen had significant improvements in biometric skin wrinkle parameters from baseline, with a reduction in volume by 46%, in area by 44%, and in depth by 9%, along with a greater increase in skin moisturization (by 34%) than those in the placebo group (p < 0.001). The food supplement did not significantly modify skin firmness or fatigue and had only slight beneficial effects on skin elasticity. The investigational product was well tolerated. The observed effects aligned closely with the subjective assessments reported by study participants. The study provides substantiated evidence supporting the efficacy of low-molecular-weight collagen peptides in restoring altered skin biometric parameters, as objectively assessed. Thus, regular supplementation with this nutraceutical may contribute to achieving smoother and more radiant skin.

Efficacy and Tolerance Evaluation of pbserum smartker Equilibrium Professional

Introduction. Skin acts as a complete barrier protecting against external aggressions and keeps the body’s internal balance. The loss of its firmness and elasticity is a complex process associated with cutaneous aging, which implies intrinsic and extrinsic factors that promote changes in the dermis, epidermis, and abnormal pigmentation. In recent years, treatments for improving skin health and beauty have advanced significantly, which has raised great interest in the related technology. Objective. To evaluate the efficacy and tolerability of pbserum smartker Equilibrium Professional in terms of skin firmness and tone improvement, wrinkle reduction, and visible signs of skin aging. Materials and Methods. A non - controlled study was carried out on 22 subjects aged 24 to 70 years old. They had normal and mixed skin with minor imperfections, excluding those with relevant dermatologic pathologies or under specific treatments. Measurements were made by subjective dermatologic evaluation, high - definition photography with the VISIA® device, and non - comedogenicity evaluation. Subjects applied the product once a week for four weeks, and the product was well tolerated with no reported adverse effects. Results. An average improvement of 27 % was observed regarding the unification of skin tone and imperfections after 28 days of use; 77 % of the patients were satisfied, and 63 % were willing to buy the product. The dermatologic evaluation did not find evidence of comedogenicity, high user satisfaction and good product tolerability. Conclusions. A significant improvement was shown in tone unification and skin imperfections, with high satisfaction from the users and a good tolerability of the product.

Antiaging, Brightening, and Antioxidant Efficacy of Fermented Bilberry Extract (Vaccinium myrtillus): A Randomized, Double-Blind, Placebo-Controlled Trial.

Strategies for successful aging, including the use of food supplements, are part of the approach to support skin youthfulness. To demonstrate the efficacy of fermented bilberry extract (FBE) against skin aging and uneven complexion, a clinical trial was carried out on 66 subjects with visible "crow's feet" wrinkles, mild-to-moderate skin slackness, and uneven skin tone. The wrinkle depth, skin smoothness (Ra) and roughness (Rz), skin firmness (R0) and elasticity (R2), skin coloration (ITA°), and skin antioxidant capacity were measured before and after 28 (D28), 56 (D56), and 84 (D84) days of product use (either FBE or a placebo). These parameters were also integrated with a clinical evaluation, carried out by a dermatologist, and a self-assessment questionnaire to align the measured efficacy with the visual or perceived efficacy. At D84, the wrinkle depth had decreased by 10.6%, Ra had improved by 7.9%, Rz had decreased by 7.3%, R0 had improved by 13.3%, R2 had improved by 12.4%, and skin antioxidant capacity had increased by 20.8%. ITA° increased by 20.8% and was accompanied by a decrease in the skin's redness component by 16.8% and an increase in the lightness component by 2.2%. The variation of all the above-mentioned parameters was statistically significant between the FBE and PL groups. Our findings demonstrate the efficacy of FBE in improving skin aging and complexion evenness.

Influence of the rehydration period on yield quality and harvest performance in Manzanilla de Sevilla super high-density olive orchards

AbstractSuper-high density olive orchards may increase profitability for table olive producers. However, water needs and fruit damage could limit their viability. Deficit irrigation scheduling would reduce the amount of water required, but rehydration before harvest is extremely important. The aim of this work was to compare a typical deficit farm management model with a regulated deficit irrigation one based on the plant water status. The experiment was carried out during three seasons in a three years-old (4 × 1.5 m) commercial table olive orchard. In both irrigation scheduling plots, seasonal amount of applied water was similar. Irrigation treatments were: common farm management (CFM), an almost constant rate of irrigation, and Regulated deficit (RDI) based on midday shaded water potential. Vegetative measurements suggested that RDI increased the external surface of the hedge, and this was related with greater yield in this treatment. Significant differences were found in of fruit size at harvest in some seasons, with larger fruits in RDI compared to CFM. However, fruit damage occurred during mechanical harvest in both irrigation managements, despite the higher skin firmness in RDI, and shows the need to carry out postharvest treatments to improve the quality of the final product. Accurate control of the tree water status would allow optimizing the amount of water available for table olive orchards.

Understanding the Interplay Between Skin, Fascia, and Muscles of the Midface in Facial Aging.

Surgical, minimally-invasive, and non-invasive aesthetic procedures try to ameliorate the signs of facial aging, but also focus on enhancing various individual features of beauty in each patient. Herein, the midface plays a central role due to its location but also its importance for the aesthetic perception and facial expression. To date, no study has investigated the interplay between facial muscles and its connecting subdermal architecture during facial aging to provide a more comprehensive understanding of the middle face. A total of 76 subjects, consisting of 30 males (39.5%) and 46 females (60.5%) with a mean age of 42.2 (18.7) years [range 19-80] and a mean BMI of 24.6 (3.7) kg/m2 [range 18-35], were enrolled in this investigation. Cutometry (skin aging), 3D skin displacement analyses (subdermal connective tissue aging), and sEMG (muscle aging) analyses were utilized. The results revealed that overall skin firmness increased, and skin elasticity decreased (p < 0.001), sEMG signal of the investigated muscles decreased (p < 0.001), whereas midfacial mobility remained unaltered (p = 0.722). The results of this study indicate that midfacial aging is a measurable effect when utilizing individual measurement modalities for assessing skin, subdermal fascia, and midfacial muscles. The function of midfacial muscles revealed a potential threshold effect, which is not reached during midfacial aging due to the unchanged soft tissue mobility at older age. However, to understand its clinical presentation all midfacial soft tissues need to be factored in and a holistic picture needs to be created.

Efficacy and Safety of Monopolar Radiofrequency for Tightening the Skin of Aged Faces

Background: Monopolar radiofrequency (RF) has emerged as a promising modality for tightening the skin of aged faces. Although many studies have assessed the efficacy of monopolar RF via the clinical evaluation of photographs, few have examined the long-term effectiveness and safety of this therapy using various skin testing devices. Methods: Twenty women with aged faces participated in this study. After a single monopolar RF treatment, three blinded dermatologists who were not involved in the treatment evaluated its clinical efficacy and safety after 4, 12, and 24 weeks. Skin firmness, fine wrinkles, skin pores, and skin tone were also measured using an indentometer (Courage+Khazaka Electronic GmbH, Köln, Germany) and a facial aging measurement device (Mark-Vu; PSI Plus, Suwon-si, Republic of Korea). Results: Skin laxity in the jowls and nasolabial folds showed significant improvement 12 weeks after the single monopolar RF treatment when evaluated by dermatologists, and this improvement lasted 24 weeks (p &lt; 0.05). Moreover, the participants reported improvement at 4 weeks compared to baseline which lasted 24 weeks (p &lt; 0.05). Skin firmness measured in the cheek increased 4 weeks after treatment and continued to improve during 24 weeks of follow-up (p &lt; 0.01). Although there was a gradual increase in improvement in skin pores, fine wrinkles, and skin tones, there were no statistical differences compared to the baseline. No patients experienced pain during the treatment, and no burns, skin breakdown, or scarring occurred after treatment. Conclusions: A single monopolar RF treatment is effective for females with aged face. A significant improvement in the jowls and nasolabial folds and facial skin firmness was observed between the 4- and 24-week follow-ups without adverse effects.

A randomized intraindividual comparative study evaluating the effects of two ultrasound-assisted liposuction devices on the abdomen

BackgroundUltrasound-assisted liposuction (UAL) has become popular because of its favorable outcomes in terms of fat emulsification, blood loss reduction, and skin tightening. This study aimed to compare the effects of two UAL devices on the abdomen by assessing postsurgery skin biomechanical properties. MethodsThis single-blind, prospective study (2020-2022) involved 13 liposuction procedures performed on patients without chronic diseases. Each patient's abdomen was divided vertically from the xiphoid to the perineum. Vibration amplification of sound energy at resonance (VASER)-assisted liposuction (Solta Medical, Inc., Hayward, CA) was performed on one half, while the other half underwent liposuction with high-frequency ultrasound energy (HEUS)-assisted technology. Skin biomechanical measurements, including distensibility, net elasticity, biological elasticity, hydration, erythema, melanin, and skin firmness, were taken at 12 and 24 months postsurgery, focusing on the anterior abdomen, 8cm to the right and left of the umbilicus. ResultsAnalysis of the above skin biomechanical measurements revealed no significant differences between the HEUS and VASER devices, except for skin firmness, which showed a notable increase following HEUS surgery. Patient-perceived clinical differences were assessed via nonvalidated questionnaires, revealing no distinctions between devices. ConclusionBiomechanical skin results post-UAL surgery with these devices on the abdomen were not significantly different, although HEUS revealed increased skin firmness. This suggests that HEUS-assisted technology, akin to other devices, is a viable option for UAL procedures.

Using an intense pulsed light (IPL) module for the treatment of pigmented lesions.

Pigmented lesions are largely benign and may lead to extreme distress. Various light and lasers may be used to treat pigmentation, often Q-switched lasers are considered the method of choice, while intense pulsed light (IPL) devices may offer a less invasive treatment with a shorter downtime. The purpose of this study is to evaluate the safety and efficacy of a narrowband IPL module for the treatment of pigmented lesions. A retrospective study of 20 patients with pigmented lesions underwent treatment with an IPL module. Treatment was assessed by blinded evaluation of clinical photographs using a GAIS scale of 0-10, as well as through patient satisfaction ratings on a scale of 0-10. Throughout the treatment, pain levels and adverse events were monitored. The mean GAIS score was 7.55 ± 1.15 (mean ± SD), and the mean patient satisfaction score was 7.3 ± 1.26 (mean ± SD). There was a strong positive correlation between GAIS and patient satisfaction scores (r = 0.83), and no significant difference between them (p-value = 0.516). The number of treatments did not significantly affect GAIS and patient satisfaction scores (p-values 0.364 and 0.126). Additional positive unexpected outcomes were improved skin firmness and reduced wrinkles. The results of the study indicate that the IPL module is both safe and effective in treating pigmented lesions and may have the potential to stimulate collagen production.

The Efficacy of a Cosmetic Preparation Containing Sheep Colostrum on Mature Skin: A Randomized Placebo-Controlled Double-Blind Study

Colostrum, the first milk produced by mammals, is rich in various bioactive components that provide numerous health benefits to newborns, such as growth factors, hormones, immunoglobulins, cytokines, and enzymes. Topical application of bovine or equine colostrum has been found to improve regeneration, accelerate cutaneous wound healing, and have moisturizing, protective, and anti-aging properties. The aim of this study was to examine the effect of a cosmetic preparation containing sheep colostrum on skin with signs of aging in mature women. Fifty-two women, aged 40–70, were randomized into two groups to receive either colostrum or placebo cream. The participants applied the cream for eight weeks. Skin hydration, TEWL, sebum, erythema, and tone were measured using a standardized Courage + Khazaka electronic GmbH Multi Probe Adapter; skin elasticity was measured with a cutometer, and images were taken by FotoMedicus. The treatment increased skin moisture, reduced TEWL, and improved skin firmness. These findings were confirmed by the subjective survey. The participants reported, inter alia, improved skin softness and less redness and hypersensitivity. Sheep colostrum cream was more effective at improving skin conditions than placebo cream. Colostrum creams can improve certain aspects of skin quality, especially the hydrolipid barrier, and overall rejuvenation.

A New Peptide Skin-Brightening Facial Cream Demonstrated Clinical Improvement in Jawline Sagging, Discoloration and Overall Photodamage

Besides fine lines and wrinkles, chronological aging leads to discoloration, age spots, and more importantly, sagging and loss of elasticity on facial skin. There are ample consumer needs to reduce age spots and skin sagging with an increasing desire for effective topical solutions that can provide meaningful benefits in these areas. A new microdipeptide (acetyl dipeptide) technology was developed that demonstrated the potential to reduce skin inflammation and stimulate the skin’s supporting matrix. This clinical study was designed to test the effectiveness of a facial cream with a unique blend of microdipeptide technology along with brightening and firming ingredients to reduce the key signs of facial aging with twice daily use. The 16-week study included 43 healthy female subjects, ages 40-70 with diverse skin tones, and having mild to moderate jawline sagging with fine lines and/or hyperpigmentation by expert visual grading (3 to 6 on a 0 to 9 scale). Visual grading exhibited statistically significant reduction in all targeted skin aging signs starting at week 8, and continuing improvement to week 16, including jawline sagging (19%), laxity (19%), lift/ firmness (15%), as well as improved evenness of skin tone (16%), hyperpigmentation (14%) and overall photodamage (23%) (mean percent change, p&lt; 0.05). Consumer perception questionnaires also revealed improvement after 16 weeks of use with tighter/tauter jawlines (88%), increased firmness (93%), skin elasticity (93%), refined facial contour (88%), less sagging (95%), and more lifted (91%) and volumized appearance (98%). Furthermore, subjects also indicated brighter skin (95%), increased radiance (93%), less discoloration (86%), fading dark spots (77%), reduced fine lines (93%) and wrinkles (95%), skin looks younger (95%), and overall less noticeable aging signs (95%). Clinical photography supported both the clinical grading and consumer perception of benefits. In addition, these clinical outcomes are further supported by in vitro and ex vivo investigations showing the microdipeptide activity on inhibiting the expression of inflammatory cytokines and inducing multiple matrix building biomarkers, beyond elastin, pro-collagen and hyaluronic acid to include decorin and fibronectin. Gene expression profiling showed changes associated with skin barrier and extracellular matrix organizations, therefore mimicking a younger-looking skin. These results demonstrated that this peptide facial cream was well-tolerated and effective in improving jawline sagging, facial skin firmness, skin brightening, and reducing the overall signs of aging.
