The skin innately possesses metabolic pathways and receptors to protect against external assaults. Here, one protective component, 7-dehydrocholesterol or provitamin D, naturally present in the skin, is described, which serves as the precursor for active metabolites that influence the formation and maintenance of barrier function, the activation of antimicrobial peptides, photoprotective activities, and protection against senescence.

This article focuses on the structure of cellulite and examines materials that claim to affect its appearance via mechanisms such as lipolysis, lipogenesis, water drainage, tissue repair and the firming of skin.

The cosmetic industry is challenged to develop active ingredients to provide the skin with a natural, healthy glow without sunlight exposure. Here, the author examines the effects of Pisum sativum extract on melanocytes and shows a time- and dose-dependent increase in skin tone, also suggesting the material could protect skin from UV damage.

In the present study, the authors produced liquid crystalline (LC) o/w emulsions whose structure mimics the skin’s intercellular lipids. These emulsions are shown in cosmetic formulations to strengthen skin barrier functions while maintaining stability at higher temperatures than that of the skin.

Dihydroxystearic acid (DHSA), derived from palm oil- or palm kernel oil-based oleic acid, offers interesting applications since its addition to oily phases and wax gels affects flow and spreading properties. Moreover, it interacts with the surfaces of pigments and fillers, improving color development as well as sensory attributes, as shown here.

Degradation of dermal and epidermal proteins and the reduced proliferation of collagen and hyaluronic acid in the dermis occur during aging. Thus, antiaging technologies must to correct these deficiencies to induce skin regeneration and combat the signs of aging. Data presented here demonstrates that ECM-derived tetrapeptides have the potential to counterbalance ECM degeneration.

While humectants and occlusive agents are the most commonly accepted approaches to moisturize skin, earlier work indicates a third approach: orthorhombic phase stabilization. In the present article, the author describes this novel mechanism of hydration and its detection by conventional and nonconventional methods, suggesting this approach could serve as a basis for all skin moisturizing therapies.

The use of steroids to treat atopic dermatitis (AD) often causes side effects; thus, the authors present a blend of plant-derived materials designed as an alternative treatment or an adjuvant therapeutic agent. Through in vitro and in vivo evaluations, the blend is shown to provide effective anti-inflammatory and AD-mitigating effects.
