Abstract: One class of cosmetic compounds that have raised interest of many experts is peptides. The search for ingredients with good biocompatibility and bioactivity has led to the use of peptides in cosmetic products. Peptides are novel active ingredients that improve collagen synthesis, enhance skin cell proliferation, or decrease inflammation. Based on their mechanism of action, they can be classified into signal peptides, carrier peptides, neurotransmitter inhibitor peptides, and enzyme inhibitor peptides. This review focuses on the main types of peptides and their application in the cosmetic field, underlining their main limitations. One of the most significant drawbacks of cosmetic peptides is their poor permeability through membranes, which limits their delivery and effectiveness. As a result, this review follows the methods used for improving permeability through the stratum corneum. Increasing peptide bioavailability and stability for enhanced delivery to the desired site of action and visible effects have become central points for the latest research due to their promising features. For this purpose, several methods have been identified and described. Physical techniques include thermal ablation (radiofrequency and laser), electrical methods (electroporation, iontophoresis), mechanical approach (microneedles), and ultrasounds. As an alternative, innovative formulations have been developed in nanosystems such as liposomes, niosomes, ethosomes, nanoemulsions, and other nanomaterials to reduce skin irritation and improve product effectiveness. The purpose of this review is to provide the latest information regarding these noteworthy molecules and the reasoning behind their use in cosmetic formulations.

Abstract

Objective: To investigate the repairing and anti-wrinkle efficacy of the facial cream enriched with C-xyloside, aiming at comprehensively evaluating its skin anti- aging effect and clarify its potential mechanism of action.

Methods: The repairing efficacy was studied on 3D epidermis skin model and the antiaging efficacy was studied on ex-vivo human skin. Two clinical studies were conducted with Chinese females. In the first study, 49 subjects aged between 30 and 50 with wrinkle concerns were recruited and instructed to apply the investigational cream containing C-xyloside for 8 weeks. Wrinkles attributes were assessed by dermatologist. Instrumental measurements on skin hydration, trans-epidermal water loss (TEWL), and skin elasticity were also conducted. In the second study, 30 subjects aged between 25 and 60 with self-declared sensitive skin and facial redness were recruited and instructed to apply the cream for 4 weeks. Biomarker analysis of the stratum corneum was conducted through facial tape strips.

Results: The cream improved the histomorphology of the 3D epidermis skin model after SLS stimulation, and significantly increase the expression of LOR and FLG. On human skin, the cream improved the histopathology induced by UV, and significantly increased the protein content of COL I and COL III, collagen density and the number of Ki-67 positive cell of skin compared with model group (n= 3, p< 0.01). The results from the first clinical study demonstrate a significant increased the skin hydration and elasticity by 21.90%, 13.08% (R2) and 12.30% (R5), respectively (n= 49, p< 0.05), and the TEWL values decreased by 33.94% (n= 49, p< 0.05), after 8 weeks application of the cream. In addition, the scores for nasolabial folds, glabellar wrinkle, underneath eye wrinkles, crow's feet wrinkle and forehead wrinkle in the volunteers exhibited a significant reduction of 34.02%, 43.34%, 50.03%, 33.64% and 55.81% respectively (n= 49, p< 0.05). The (rCE)/(fCE) ratio of volunteers based on tape stripping significant increased after using the sample cream (n= 30, p< 0.05).

Conclusion: The cream containing C-xyloside showed improvement of skin wrinkles and enhancement of skin barrier function. These efficacies may be attributed to the fact that the sample cream can increase the expression of skin barrier related proteins LOR and FLG, promote the maturation of cornified envelope, enhance collagen I and III protein expression and stimulate skin cell proliferation, to provide sufficient evidence supporting its antiaging efficacy of skin.

Abstract: This comprehensive review explores the pivotal roles of glycation and oxidative stress in the aging process of the skin, their targeted therapeutic applications in aesthetic and regenerative medicine, as well as anti-aging interventions. Glycation, a biochemical process involving the non-enzymatic attachment of sugars to proteins, lipids, or nucleic acids, culminates in the formation of Advanced Glycation End products (AGEs). These AGEs are significant contributors to aging and various chronic ailments, triggering oxidative stress and inflammatory pathways, thereby manifesting as wrinkles, diminished skin elasticity, and other age-related dermal alterations. A central focus of this review is the synergistic interplay between Hyaluronic Acid (HA) and Trehalose in combating these aging mechanisms. HA, renowned for its anti-inflammatory and antioxidative properties, assumes a pivotal role in modulating Reactive Oxygen Species (ROS) levels and safeguarding against oxidative damage. Concurrently, trehalose targetsglycation and oxidative stress, exhibiting promising outcomes in augmenting skin health, providing Ultraviolet B (UVB) photoprotection, and manifesting notable anti-photoaging effects. The combined administration of HA and trehalose not only addresses existing skin damage but also confers preventive and reparative benefits, particularly in stabilizing HA and mitigating glycation-induced stress. Their synergistic action significantly enhances skin quality and mitigates inflammation. The implications of these findings are profound for the future of anti-aging therapeutics in aesthetic medicine, suggesting that the integration of HA and trehalose holds promise for revolutionary advancements in preserving skin vitality and health. Moreover this paper underscores the imperative for continued research into the combined efficacy of these compounds, advocating for innovative therapeutic modalities in aesthetic medicine and enhanced strategies for combating aging, glycation, and oxidative stress.
