Facial Anti-Aging Treatments with Soft Peeling and Microneedling Technique

Background: The interest in maintaining a young and attractive appearance in an era with increasingly hectic rhythms has generated a pressing demand for effective aesthetic procedures with the shortest possible recovery period, stimulating the search for non-invasive, yet successful, solutions. The aim of this study was to evaluate the effectiveness of the combined soft peeling and MN technique on the various imperfections typical of facial aging. Methods: This multicentric uncontrolled experimental study recruited a population of healthy subjects of both sexes with advanced signs of photo- and chrono-aging. These subjects were provided with a single session of microneedling and peeling at the same time. Recruited subjects were re-evaluated 30 (±4) and 60 (±4) days after treatment by photographic comparison before and after treatment. The physicians evaluated the improvement of facial wrinkles according to the Wrinkle Assessment Scale of Lemperle. Forty-nine subjects completed the study and showed a significant improvement in wrinkles in all areas of the face. Results: There were no significant differences in the different subpopulations compared: males–females, Glogau 3–Glogau 4, smokers–non-smokers, phototypes 1–4, and check up at 30 days–control at 60 days. The adverse events manifested were localized edema in four cases (8.2%) lasting an average of 3–4 days, very fine crustiness in four cases (8.2%), transient post inflammatory dyschromia in two cases (4.1%) lasting 2–3 weeks, and herpetic reactivation in one case (2.0%). Conclusions: The study demonstrates the therapeutic efficacy of the combined needling-peeling treatment in different types of wrinkles.

Hydrogen’s Antiaging and Whitening Effects on Skin

This study was conducted to confirm the suitability of hydrogen as a functional cosmetic ingredient by evaluating the anti-aging and whitening effect of hydrogen, known as an excellent antioxidant. Cosmetic hydrogen powder was prepared to investigate its inhibitory activity on elastase, collagenase, and tyrosinase, and a hydrogen pack was produced using the prepared cosmetic powder to conduct clinical trials. The results showed that hydrogen powder had excellent anti-aging activation and whitening effect. In clinical trials, skin elasticity was increased by 15%, skin sagging decreased by 4.53%, and skin tone improved by 4.86%, compared to the control group. These results suggest that hydrogen has excellent anti-aging and whitening effect. Therefore, it is highly likely that hydrogen can be used as a functional cosmetic ingredient for wrinkle improvement and skin whitening.

Helium plasma dermal resurfacing: VISIA CR assessment of facial spots, pores, and wrinkles-Preliminary findings.

ObjectivesEffects of low energy, single‐pass helium plasma dermal resurfacing (PDR) treatment on brown spots, enlarged pores, and wrinkles—preliminary findings.MethodsTwenty two subjects (64.6 ± 6.6 years) with Fitzpatrick Wrinkle and Elastosis Scale score (FWS) of ≤2 and seeking improvement of facial appearance were included in this subanalysis. All subjects received a single, one‐pass, full face, and low power helium PDR treatment. Standard digital images were collected using the VISIA‐CR (Canfield Scientific Inc.) at baseline and 3 months after treatment with images assessed for improvement in FWS and for improvements in brown spots, enlarged pores, and wrinkles by proprietary automated image processing algorithms.ResultsNearly all subjects demonstrated ≥1‐point improvement in FWS and also reported improvement per modified Global Aesthetic Improvement Scale query. The numbers of brown spots and enlarged pores decreased by 45.1% and 28.3%, respectively. Stratification of brown spots data by presence or absence of post‐inflammatory hyperpigmentation revealed paradoxically conflicting data. The improvement detected in wrinkle area and mean wrinkle thickness was less pronounced with overall reductions of 13.4% and 4.8%, respectively. 37 Non‐serious adverse events (AEs) in 22 subjects were reported with most resolving within 14 days or less, and no serious AEs were observed.ConclusionsWhile longer‐term follow‐up is needed, these early study results show that one single‐pass, low energy helium PDR treatment improves facial skin appearance both qualitatively and quantitatively. Studies evaluating higher energy levels and multiple treatment passes are ongoing.

Prospective Randomized Controlled Trial on the Effects of Almonds on Facial Wrinkles and Pigmentation.

Background: Almonds have long been studied as a rich source of fatty acids, phytochemical polyphenols and antioxidants such as vitamin E. A recent study compared almond supplementations to a calorie-matched intervention for 16 weeks, yielding statistically significant improvement in wrinkle severity in postmenopausal women with Fitzpatrick skin types I and II that received almonds. This study furthers that assessment with a larger population and duration of 24 weeks to assess the influence of almond consumption on wrinkle severity, skin pigmentation and other skin biophysical profiles. Objective: To investigate the effects of almond consumption on photoaging such as wrinkles and pigment intensity as well as facial biophysical parameters such as sebum production, skin hydration and water loss. Design and interventions: A prospective, randomized controlled study assessed postmenopausal women with Fitzpatrick skin types I or II who consumed 20% of their daily energy consumption in either almonds or a calorie-matched snack for 24 weeks. A facial photograph and image analysis system was used to obtain standardized high-resolution photographs and information on wrinkle width and severity at 0, 8, 16 and 24 weeks. Measurements of transepidermal water loss (TEWL), skin pigmentation, skin hydration and sebum production were also completed at each visit. Results: The average wrinkle severity was significantly decreased in the almond intervention group at week 16 and week 24 compared to baseline by 15% and 16%, respectively. Facial pigment intensity was decreased 20% in the almond group at week 16 and this was maintained by week 24. There were no significant differences in skin hydration or TEWL in the almond group compared to the control, although sebum excretion was increased in the control group. Conclusion: The daily consumption of almonds may improve several aspects of photoaging such as facial wrinkles and pigment intensity in postmenopausal women. In conclusion, the daily consumption of almonds may contribute to the improvement of facial wrinkles and reduction of skin pigmentation among postmenopausal women with Fitzpatrick skin types I and II.

Treatment of periorbital and perioral wrinkles with fractional Er:YAG laser: What are the effects of age, smoking, and Glogau stage?

Dynamic and static wrinkling are observed on the facial skin as a result of aging. Previously, it was showed that fractional Er:YAG laser was effective in the treatment of facial wrinkles. The aims of this study are to determine the effects of age, Glogau stage, and smoking status on the treatment efficacy of fractional Er:YAG laser; and to compare the success of laser treatment on periorbital wrinkles with perioral wrinkles. Periorbital and perioral wrinkles of the same patient were treated with fractional Er:YAG laser (2940nm) for 4 sessions with monthly intervals. Treatment parameters were affluence of 1.5J, a spot size of 7mm, and a frequency of 5Hz. Treatment efficacy was evaluated by a blinded physician evaluation scale and patient satisfaction scale 2months after the final treatment session. Fifteen patients completed the study. The mean age of the patients was 42.8years. The blinded physician evaluation of the improvement in the periorbital wrinkles decreased (P=.034) and the patient satisfaction in perioral wrinkles decreased (P=.049) with increasing age. The relationship between smoking and patient satisfaction in the treatment of periorbital wrinkles was also statistically significant (P=.014). No difference in terms of treatment efficacy was found between periorbital and perioral regions. Fractional Er:YAG laser (2940nm) is equally successful in the treatment of periorbital and perioral wrinkles. The treatment success decreases with smoking and increasing age.

Enhancement of elastin expression by transdermal administration of sialidase isozyme Neu2

Reduction of elastin in the skin causes various skin diseases as well as wrinkles and sagging with aging. Sialidase is a hydrolase that cleaves a sialic acid residue from sialoglycoconjugate. Cleavage of sialic acid from microfibrils by the sialidase isozyme Neu1 facilitates elastic fiber assembly. In the present study, we showed that a lower layer of the dermis and muscle showed relatively intense sialidase activity. The sialidase activity in the skin decreased with aging. Choline and geranate (CAGE), one of the ionic liquids, can deliver the sialidase subcutaneously while maintaining the enzymatic activity. The elastin level in the dermis was increased by applying sialidase from Arthrobacter ureafaciens (AUSA) with CAGE on the skin for 5 days in rats and senescence-accelerated mice prone 1 and 8. Sialidase activity in the dermis was considered to be mainly due to Neu2 based on the expression level of sialidase isozyme mRNA. Transdermal administration of Neu2 with CAGE also increased the level of elastin in the dermis. Therefore, not only Neu1 but also Neu2 would be involved in elastic fiber assembly. Transdermal administration of sialidase is expected to be useful for improvement of wrinkles and skin disorders due to the loss of elastic fibers.

Comparison of Microfat, Nanofat, and Extracellular Matrix/Stromal Vascular Fraction Gel for Skin Rejuvenation: Basic Research and Clinical Applications.

Over the past 2 decades, fat grafting has been extensively applied in the field of tissue regeneration. The aim of this study was to investigate the therapeutic potential of microfat, nanofat, and extracellular matrix/stromal vascular fraction gel (SVF-gel) in skin rejuvenation. Microfat was harvested by a cannula with multiple 0.8-mm smooth side holes and processed with a fat stirrer to remove fibers. Nanofat and SVF-gel were prepared according to previously reported methods, and their structure and viability were evaluated. Then, SVF cells from the 3 types of samples were isolated and characterized, and the cell viability was compared. The microstructure of the 3 samples showed distinct differences. The microfat group showed a diameter of 100 to 120.0 μm under the microscope and presented a botryoid shape under calcein acetoxymethyl (calcein-AM)/propidium iodide staining. Scanning electron microscopy analysis showed that the microfat maintained an integral histologic structure. In the nanofat group, no viable adipocytes and no normal histologic structure were observed, but high levels of free lipids were noted. The SVF-gel group showed uniform dispersion of cells with different sizes and parts of the adipose histologic structure. Cell count and culture revealed that the number of viable SVF cells decreased distinctly in the nanofat group compared with the microfat group. In contrast, the number of viable SVF cells in the SVF-gel group increased moderately. Clinical applications with microfat showed marked improvements in skin wrinkles. Microfat can preserve the integrity of the histologic structure and presents the advantages of subcutaneous volumetric restoration and improvement of skin quality in skin rejuvenation compared with the nanofat and SVF-gel.

Transcriptome Profiling of Human Follicle Dermal Papilla Cells in response to Porphyra-334 Treatment by RNA-Seq.

Porphyra-334 is a kind of mycosporine-like amino acid absorbing ultraviolet-A. Here, we characterized porphyra-334 as a potential antiaging agent. An in vitro assay revealed that porphyra-334 dramatically promoted collagen synthesis in fibroblast cells. The effect of porphyra-334 on cell proliferation was dependent on the cell type, and the increase of cell viability by porphyra-334 was the highest in keratinocyte cells among the three tested cell types. An in vivo clinical test with 22 participants demonstrated the possible role of porphyra-334 in the improvement of periorbital wrinkles. RNA-sequencing using human follicle dermal papilla (HFDP) cells upon porphyra-334 treatment identified the upregulation of metallothionein- (MT-) associated genes, confirming the antioxidant role of porphyra-334 with MT. Moreover, the expression of genes involved in nuclear chromosome segregation and the encoding of components of kinetochores was upregulated by porphyra-334 treatment. Furthermore, we found that several genes associated with the hair follicle cycle, the hair follicle structure, the epidermal structure, and stem cells were upregulated by porphyra-334 treatment, suggesting the potential role of porphyra-334 in hair follicle growth and maintenance. In summary, we provided several new pieces of evidence of porphyra-334 as a potential antiaging cosmetic agent and elucidated the expression network in HFDP cells upon porphyra-334.

Efficacy and safety of non-thermal nitrogen plasma versus long-pulsed Nd:YAG laser for hand rejuvenation.

This randomized controlled study aimed to investigate the efficacy and safety of multiple treatment sessions of pulsed non-thermal atmosphericpressure nitrogen plasma compared with long-pulsed Nd:YAG laser for hand rejuvenation. To optimize the nitrogen plasma mode for rejuvenation, the relative intensity of reactive species and skin temperature was compared at different input powers and time periods. Twenty-five patients with mild-moderate photodamaged skin were recruited; one hand was randomly selected for eightweekly treatment sessions with plasma (two passes), while the other was subjected to threemonthly treatments with laser (until erythema became obvious). A blinded dermatologist scored the mean wrinkle and dyschromia improvement at 1 and 2months after the first treatment and 1 and 3months after the last treatment. The patients' satisfaction and the biomechanical characteristics of the skin including cutaneous resonance running time (CRRT), melanin, transepidermal water loss (TEWL), and hydration were evaluated. Clinically, both methods gave rise to a similar, significant improvement in wrinkles (49.09 ± 19.18% and 39.32 ± 18.21% after plasma and laser, respectively) and dyschromia (45.00 ± 26.32% and 30.62% ± 24.99% after plasma and laser, respectively) (P < 0.05). A significant decrease in CRRT and melanin was seen following treatment with either method (P < 0.05). Notably, plasma therapy led to a significant decrease in TEWL and boosted skin hydration. This is while laser therapy augmented the TEWL and reduced skin hydration. Our findings corroborate that cold plasma is as effective and safe as long-pulsed Nd:YAG laser, with less discomfort and dryness during treatment. The protocol was approved by the Iranian Registry of Clinical Trials. IRCT20160320027109N4. Registered 9 April 2019 (This manuscript is only a part of this registered project.).

Efficacy study of the new polycaprolactone thread compared with other commercialized threads in a murine model.

BackgroundPolydioxanone (PDO) threads, poly‐L‐lactic acid (PLLA) threads, and polycaprolactone (PCL) threads have been used for lifting and antiaging purposes. The new PCL threads that have less residual monomer compared to the previous PCL are developed.AimsThe efficacy of threads regarding collagen synthesis and wrinkle improvement was evaluated in vivo model.MethodsIn this study, threads were inserted into 30 six‐week‐old male SKH‐1 hairless mice. One of four threads was implanted at either side of the spine of each mouse. Biopsy specimens obtained at 1, 4, and 8 weeks were examined using hematoxylin and eosin (H&E) and Herovici's stain. Additionally, immunoblot analysis was performed using primary antibody for collagen type III and transforming growth factor‐β (TGF‐β) and visualized by chemiluminescence and densitometric quantification. Finally, skin replicas were used to calculate total wrinkle area (mm2).ResultsNeocollagenesis was significantly increased by 50% in the new PCL and pre‐existing PCL groups at 8 weeks (p value < 0.001). Additionally, new‐PCL‐implanted mice showed a significant increase in collagen type III and TGF‐β expressions at 8 weeks (p value < 0.001). The number of inflammatory cells was also increased in the skin of PCL‐implanted mice at 8 weeks. Finally, wrinkles were reduced about 20% in the new PCL group at 8 weeks.ConclusionsThe new PCL thread exhibited a superior skin rejuvenation effect. This suggests that the material processing technology can be applied not only to the thread but also to various products such as dermal filler and cosmetics.

Effect of Microfocused Ultrasound on Facial Rejuvenation: Clinical and Histological Evaluation

Introduction: Micro focused ultrasound (MFU) is formed by mechanical waves emitted in a focused manner, concentrating thermal energy on a certain point or region, promoting a clinical improvement in wrinkles. Objective: evaluate the effects of micro focused ultrasound on facial rejuvenation. Methodology: This is an experimental study. The sample consisted of 30 volunteers, who were evaluated before treatment, 45 and 90 days after its beginning. A single application of the MFU was performed across the facial region. The parameters used were: 10 MHz cartridge with depth of 1.5 mm, 7 MHz with depth of 3 mm, and 4 MHz with focal depth of 4.5 mm; doses ranged from 0.1 to 2.0 J, according to the sensitivity of the volunteers treated, and the application time was of approximately 90 minutes. Clinical photographic analysis and facial symmetry analysis using Dolphin Imaging software were performed, and validated questionnaires. Two volunteers were submitted to blepharoplasty surgery, and one to rhytidoplasty surgery 45 days after the application of the MFU. Samples of the treated skin were taken after the surgical procedures and submitted to histological and immunohistochemical analyses. The volunteers answered a questionnaire to assess adverse reactions and satisfaction. Results: We observed a visible clinical improvement on the images by photography, and an improvement of facial symmetry in the measurements of the paralateronasal projection (p = 0.007), left lateral mandibular (p = 0.01), and right lateral mandibular (p = 0.008). The histological analysis showed an increase in the amount of fibroblasts (p = 0.02), blood vessels (p = 0.0062) and inflammatory cells (p = 0.0036), in addition to the production of type 1 collagen. In the immunohistochemical analysis, we observed the presence of the macrophage marker IHQ: CD68, indicating phagocytosis of adipose tissue and the presence of fibrosis. In the analysis of adverse reactions, only transient hyperemia was observed with the presence of pain during application. Additionally, the volunteers expressed high level of satisfaction (93%) with the treatment Conclusion: The MFU promoted the production of collagen, reorganization of the dermis and, clinically, a reduction of sagging and wrinkles, with increased facial symmetry.

Adipose tissue micrograft in a scaffold of plasma-gel combined with platelet-derived growth factors in dermal wrinkle regeneration

Background: The dermal aging process and the formation of deep wrinkles are a biological involution that also involves the regeneration system of cells immersed in the extracellular matrix and the papillary dermis. The progressive loss of niches of adult stem cells (MSCs) is more evident after the first third of life; it increases the phenotypic expression and the characteristics of the tissue senescence process. The purpose of this study was to clinically demonstrate that in viable micrograft there may be an improvement of deep wrinkles and surrounding tissues. Methods: This study involved 11 female patients who underwent the correction of deep dermal wrinkles through a suspension containing 0.8 mL of viable micrografts in a 5 mL plasma gel scaffold, obtained from the centrifugation of a 20 cc venous sample peripheral blood, gelled by heat in a dry steriliser and the buffy coat coming from the same venous sample, in order verify overtime the improvement of the interested anatomical area. Individual signs of wrinkles and the degree of correction obtained for each treatment and each area were objectively evaluated by using a 10-0 visual analog scale (VAS), Modified Vancouver scale and Berardesca's scale. Results: With this technique excellent results were obtained. In fact, wrinkles were improved, as well as surrounding tissues, even after 60 days, as shown by the Berardesca's, VAS and Modified Vancouver scales. Conclusion: This retrospective clinical evaluation allowed us to consider the excellent clinical results obtained with this method for the treatment of deep wrinkles and surrounding tissues, through a suspension of progenitors with MSCs derived from adipose tissue (ADSCa) in a not inflammatory plasma gel scaffold combined with buffy coat.
