Assessing the Anti-Aging and Wound Healing Capabilities of Etlingera elatior Inflorescence Extract: A Comparison of Three Inflorescence Color Varieties.

Torch ginger, Etlingera elatior, is a Zingiberaceae plant with various red, pink, and white inflorescence. The wound healing potential and anti-aging effects of freeze-dried torch ginger inflorescence extracts (FTIEs) from three varieties were compared. The red FTIE had the highest content of phenolic, flavonoid, caffeoylquinic acid, and chlorogenic acid, followed by the white and pink FTIE. Consistent with the chemical constituents, the red FTIE demonstrated the greatest capacities for free radical scavenging, anti-tyrosinase, and anti-collagenase activity, followed by the white and pink FTIE. In cell-based studies, FTIEs displayed cytotoxicity to B16F10 melanoma cells, with the red FTIE showing the greatest activity (LC50 of 115.5 μg/mL). In contrast, the pink and the white FTIEs had less cytotoxicity impact. Nonetheless, at 1000 μg/mL, all three FTIE variants were safe on L929 fibroblasts or RAW 264.7 monocyte cells. White FTIE (500 μg/mL) exhibited the highest activity in stimulating collagen production and the greatest impact on cell migration, whereas the pink and red FTIE had a lesser effect. All FTIEs slightly suppressed the pro-inflammatory cytokines produced by lipopolysaccharide-stimulated monocytes, with no significant variation between FTIE variants. In conclusion, all FTIEs revealed promising potential for anti-aging cosmeceuticals and wound care products at specific concentrations.

A Cost-Based Analysis of Anti-aging Products Across Four Major United States Retailers.

Background In the field of aesthetic dermatology, there is currently very little data on affordability and cost analysis regarding cosmeceuticals as more demand from patients showing interest in cosmeceutical products to reduce and prevent aging continues to grow.Photoaging, a form of extrinsic aging from sun exposure, can be ameliorated by applying sunscreen and retinol products. Topical ascorbic acid and niacinamide have been shown to target the oxidative stress process that contributes to photoaging.These four products have been identified as the cosmeceutical ingredients with the most evidence-based data on photoaging prevention and treatment. Objective Given the demand for effective skin care,the paucity of data on cost differentiation, and the availability of cosmeceutical products, we analyzed the unit cost offour anti-aging products from major online and physical retailers in the United States. Such a cost comparison may facilitate more economically appropriate recommendations on skin care to consumers. Methods and materials We analyzed sunscreen, topical vitamin C (ascorbic acid), topical vitamin B3 (niacinamide), and topical vitamin A (retinol) products sold by four major United States retailers: Walmart, Ulta, Walgreens, and Amazon. The average cost in dollars per ounce (dollar/oz) was calculated for each product category at each retailer. Statistical analyses were done to determine statistical significance for each product category between retailers as well as between each category of product. Results Between the four retailers, Walmart offered the lowest cost per ounce for every product. In contrast, Amazon offered the highest cost per ounce for every product except for sunscreen. We also found that sunscreen products are less expensive per ounce as compared to retinol, ascorbic acid, and niacinamide products. Conclusion Dermatologists should be knowledgeable of product costs when providing patients with anti-aging product recommendations. Our study provides data on the financial cost by retail location of evidence-based anti-aging cosmeceuticals to better guide physicians in patient consulting and economical resource sharing.

Evaluation of Citrus junos Essential Oil as a Promising Anti-aging Ingredient: In Vitro and Clinical Studies on Skin Health Improvement

Purpose: This study assessed Citrus junos essential oil (CJEO) as an anti-aging agent for improving skin health.Methods: CJEO was extracted from authenticated C. junos fruit peels, and its chemical composition was analyzed using a gas chromatographymass spectrometry (GC-MS). In vitro experiments were conducted on human epidermal keratinocytes (HEKs) and human dermal fibroblasts (HDFs) to evaluate CJEO’s impact on cell viability, anti-inflammatory activity, collagen synthesis, and collagen degradation. The expression of TNF-α, IL-1β, IL-6, NF-κB, MMP-1, MMP-3, COL1A1, and COL3A1 was quantified using RT-qPCR. A dermal patch test was performed on human participants to assess potential skin irritation, and clinical evaluations were conducted on 20 female participants to analyze CJEO’s effects on skin elasticity.Results: CJEO effectively inhibited nitric oxide production and significantly suppressed the expression of inflammatory markers, including TNF-α, IL-1β, IL-6, and NF-κB, as well as collagen degradation markers MMP-1 and MMP-3. Furthermore, CJEO treatment upregulated the expression of genes associated with collagen synthesis, specifically COL1A1 and COL3A1. Notably, significant improvements in skin elasticity were observed in the 20 female participants. The dermal patch test indicated excellent tolerance of the CJEO emulsion without causing irritation.Conclusions: CJEO exhibits promising potential as a bioactive ingredient in anti-aging cosmeceuticals. Its anti-inflammatory properties, ability to stimulate collagen synthesis, suggest efficacy in reducing skin aging and promoting overall skin health. Additionally, the dermal patch test confirms CJEO’s safety, supporting its suitability for use in cosmetic formulations. These findings endorse CJEO as an effective and safe component in anti-aging skincare products.

In Vitro and In Silico Evaluations of Boswellia carterii Resin Dermocosmetic Activities

Boswellia carterii is a plant species belonging to the Burseraceae family. It grows up in trees or shrubs, and it is known for producing an aromatic resin commonly named frankincense or olibanum. This resin has been used in traditional medicine to treat various conditions such as inflammations, gastrointestinal disorders and traumatic injuries. Virtual screening and molecular docking are two in silico approaches used to predict potential interactions between ligands and the active site of a protein. These approaches are mainly used in natural product chemistry and pharmacology as a screening tool to select plant extracts or fractions for in vitro testing, as well as for the prediction of mechanisms of action. The aim of this research is the in silico and in vitro evaluations of the potential collagenase and elastase inhibitory activities of Boswellia carterii resin organic extracts (viz., methanol, n-hexane and ethyl acetate). The obtained results revealed that methanol and n-hexane exhibited the best collagenase inhibitory activity with values superior to 85%, whereas the methanol and ethyl acetate showed the highest elastase inhibition activity with inhibition values ranging between 40 and 60%. The molecular docking prediction confirmed the experimental results; moreover, the visualization of the ligand–protein interactions showed that the main compounds of the organic extracts may have mechanisms of action similar to the positive controls. Those findings are very promising and open new perspectives for the exploitation of Boswellia carterii resin as active agents for the development of anti-aging cosmeceuticals.

Phytoformulation studies on Traditional Anti-Wrinkle Preparation

The most frequent dermatological concern and a multisystem degenerative process is skin aging. Age related factors may be either due to declining physiological functions (intrinsic aging) or may be due to environmental factors such as pollution, sun exposure, smoking, stress etc. (extrinsic aging). An aged skin displays pigmented lesions, patchy hypopigmentations, actinic keratoses, fragility, laxity and wrinkles. Skin aging mechanisms involve biochemical changes in collagen, elastin and connective tissues, thereby resulting in a thin, dry, less elastic, wrinkled skin. In the recent years, herbals are largely preferred to synthetic drugs regarding to their traditional use as they help in providing an efficient, low toxicity and cost impressive product. Though a number of traditional plants are available, novel delivery systems need to be integrated so that the efficacy and cost effectiveness of the therapy can be optimized. Functional herbal active constituents and innovative novel formulations are driving the cosmetic industry. This present review put forward extensively on herbs appraisal for skin aging treatment. It also highlights the benefits of herbals and their role in impeding aging of skin. Some commercial branded herbal anti-aging cosmeceuticals and a few novel anti-aging herbal formulations available in the market are also reviewed here.

Antiaging Cosmeceuticals in Korea and Open Innovation in the Era of the 4th Industrial Revolution: From Research to Business

The importance of the healthcare industry has increased and it has thrived, although the cosmetic industry of Korea has been in depression. A recently issued group of items in Korea, ‘cosmeceuticals’, is defined as a combination of pharmaceuticals and cosmetics proven to have medical effectiveness. Antiaging cosmeceuticals in Korea have performed well in terms of expanding business by combining with beauty services, so they are viewed as high-valued items. This fact supports the evidence that there are various studies on cosmeceuticals. Therefore, this paper shows that the global status and growth potential of cosmeceuticals are documented and the concepts of the application of the demonstration complex and open innovation will be linked together based on research of antiaging cosmeceuticals in Korea for an aging society. This paper intends to provide the basic information for forming a ‘lab to market’ which connects the future cosmeceutical laboratory to the market.

Cosmeceuticals for Male Skin.

The male cosmeceutical market is still underdeveloped. Although women embrace skin care as a part of general health, this concept has not gained wide male acceptance. Shaving is probably the most beneficial daily grooming event men commonly undertake for skin appearance and may account for the failure of antiaging cosmeceuticals to attract attention in this segment. In addition, there are many physiologic differences between male and female skin, with less of a need for moisturization and photoprotection in men. This article highlights some of the differences between male and female skin along with the unique product attributes required to address these differences.

In vitro inhibition of hyaluronidase by sodium copper chlorophyllin complex and chlorophyllin analogs.

BackgroundInhibitors of hyaluronidase are potent agents that maintain hyaluronic acid homeostasis and may serve as anti-aging, anti-inflammatory, and anti-microbial agents. Sodium copper chlorophyllin complex is being used therapeutically as a component in anti-aging cosmeceuticals, and has been shown to have anti-hyaluronidase activity. In this study we evaluated various commercial lots of sodium copper chlorophyllin complex to identify the primary small molecule constituents, and to test various sodium copper chlorophyllin complexes and their small molecule analog compounds for hyaluronidase inhibitory activity in vitro. Ascorbate analogs were tested in combination with copper chlorophyllin complexes for potential additive or synergistic activity.Materials and methodsFor hyaluronidase activity assays, dilutions of test materials were evaluated for hydrolytic activity of hyaluronidase by precipitation of non-digested hyaluronate by measuring related turbidity at 595 nm. High-performance liquid chromatography and mass spectroscopy was used to analyze and identify the primary small molecule constituents in various old and new commercial lots of sodium copper chlorophyllin complex.ResultsThe most active small molecule component of sodium copper chlorophyllin complex was disodium copper isochlorin e4, followed by oxidized disodium copper isochlorin e4. Sodium copper chlorophyllin complex and copper isochlorin e4 disodium salt had hyaluronidase inhibitory activity down to 10 µg/mL. The oxidized form of copper isochlorin e4 disodium salt had substantial hyaluronidase inhibitory activity at 100 µg/mL but not at 10 µg/mL. Ascorbate derivatives did not enhance the hyaluronidase inhibitory activity of sodium copper chlorophyllin. Copper isochlorin e4 analogs were always the dominant components of the small molecule content of the commercial lots tested; oxidized copper isochlorin e4 was found in increased concentrations in older compared to newer lots tested.ConclusionThese results support the concept of using the hyaluronidase inhibitory activity of sodium copper chlorophyllin complex to increase the hyaluronic acid level of the dermal extracellular matrix for the improvement of the appearance of aging facial skin.

Pectin Micro- and Nano-capsules of Retinyl Palmitate as Cosmeceutical Carriers for Stabilized Skin Transport.

Retinyl palmitate (RP)-loaded pectinate micro- and nano-particles (PMP and PNP) were designed for stabilization of RP that is widely used as an anti-wrinkle agent in anti-aging cosmeceuticals. PMP/PNP were prepared with an ionotropic gelation method, and anti-oxidative activity of the particles was measured with a DPPH assay. The stability of RP in the particles along with pectin gel and ethanolic solution was then evaluated. In vitro release and skin permeation studies were performed using Franz diffusion cells. Distribution of RP in each skin tissue (stratum corneum, epidermis, and dermis) was also determined. PMP and PNP could be prepared with mean particle size diameters of 593~843 μm (PMP) and 530 nm (i.e., 0.53 μm, PNP). Anti-oxidative activity of PNP was greater than PMP due largely to larger surface area available for PNP. The stability of RP in PMP and PNP was similar but much greater than RP in pectin bulk gels and ethanolic solution. PMP and PNP showed the abilities to constantly release RP and it could be permeated across the model artificial membrane and rat whole skin. RP was serially deposited throughout the skin layers. This study implies RP loaded PMP and PNP are expected to be advantageous for improved anti-wrinkle effects.

Cosmeceuticals for children: should you care?

Cosmeceuticals are substances that exert physiologic changes to the skin for aesthetic purposes and are popular alternatives to invasive cosmetic procedures for antiaging. Cosmeceuticals are being used on children; yet studies of cosmeceuticals in the pediatric population are limited. Cosmeceuticals remain an unrecognized category by the US Food and Drug Administration, and therefore stringent regulatory pathways do not exist to guide research and marketing. To date, no safety and efficacy study exists on cosmeceutical use in pediatric patients. Increasing knowledge of the mechanisms underlying intrinsic and extrinsic skin aging, including reactive oxygen species formation, effects of declining hormones, and ultraviolet radiation, forms the scientific basis for common cosmeceuticals such as retinoids, botanicals such as soy isoflavones, and even moisturizers and sunscreen. Virtually all studies on cosmeceuticals have been performed in women with varying degrees of skin aging. The cosmeceuticals most likely to be used by younger children are moisturizers and sunscreens. As the popularity and availability of other antiaging cosmeceuticals grow, practitioners will encounter more and more beauty-conscious teenagers using these products for preventive rather than restorative purposes. Pediatricians should be familiar with the use of common cosmeceuticals used in children, especially the use of broad-spectrum sunscreen. In the future, more children will be exposed to cosmeceuticals and may experience side effects such as contact dermatitis and skin irritation.

Chitooligomers inhibit UV-A-induced photoaging of skin by regulating TGF-β/Smad signaling cascade

Abstract In the present study, effect of low molecular weight chitooligomers on prevention of photoaging in UV-A irradiated in vitro human dermal fibroblasts was investigated. The results indicated that chitooligomers suppressed family of collagenase (MMP-1, MMP-8 and MMP-13) and gelatinase (MMP-2 and MMP-9) MMPs expression. These levels were inhibited by increase in expression of TIMP-1 and TIMP-2 genes. In addition, treatment with chitooligomers enhanced the expression of collagen synthetic markers such as procollagen and type I collagen in UV-A irradiated dermal fibroblasts. Furthermore, we confirmed that the UV-A-induced transcriptions of AP-1 and TGF-β/Smad signaling cascade were regulated by chitooligomers treatment in UV-A irradiated dermal fibroblasts. Therefore, our study suggests that chitooligomers can be developed as topical application of natural anti-aging cosmeceuticals since reduced the skin collagen decomposition by enhancement of collagen synthesis.

Theories and management of aging: modern and ayurveda perspectives.

Aging is a complex phenomenon, a sum total of changes that occur in a living organism with the passage of time and lead to decreasing ability to survive stress, increasing functional impairment and growing probability of death. There are many theories of aging and skin remains the largest organ of the study. Skin aging is described as a consequence of intrinsic and extrinsic factors. The most common amongst visible signs of skin aging are wrinkles and there are various therapies including antiaging cosmeceuticals, sunscreens, chemical peeling, injectable agents, such as botox, fibrel, autologous fat grafting as also few surgical procedures have been used. Ayurveda, the Indian traditional medicine, describes aging with great details. This review provides modern and Ayurvedic perspectives on theories and management of aging.

The clinical anti‐aging effects of topical kinetin and niacinamide in Asians: a randomized, double‐blind, placebo‐controlled, split‐face comparative trial

Kinetin and niacinamide are used in the cosmetic industry as anti-aging agents. Neither the interactive/additive effects of these compounds nor the anti-aging efficacy on Asian skin has been studied. Objective To assess the clinical anti-aging effects and efficacy differences between kinetin plus niacinamide and niacinamide alone vs. vehicle placebo in an Asian cohort. Fifty-two Taiwanese subjects were enrolled in a randomized, double-blind, placebo-controlled, split-face comparative study. Group 1 subjects were treated with kinetin 0.03% plus niacinamide 4%, whereas group 2 subjects received niacinamide 4%. The treatment formulation was applied on one side of the face, whereas a placebo was applied on the other for a period of 12 weeks. We used noninvasive biometrological instruments to evaluate a variety of skin parameters at baseline and at weeks 4, 8, and 12. Persistent and significant reductions in spot, pore, wrinkle, and evenness counts were found at weeks 8 and 12 in group 1. A significant increase in corneal hydration status was also evident at week 12, whereas persistent decreases in erythema index were apparent at 8 and 12 weeks. In group 2, significant reductions in pore and evenness counts at week 8 and wrinkle counts at week 12 were noted. We found kinetin and niacinamide exert a synergistic anti-aging effect. Our data suggest that these compounds have multiactive, multifunctional, and pluripotent effects on skin. They are also both promising to be included in the cutaneous anti-aging cosmeceuticals in the future.
