Metabolism of Vitamin D in Skin: Benefits for Skin Care Applications
By: Françoise Arnold MMP Sarl; Michel Merci…
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.

Liquid Crystal O/W Emulsions to Mimic Lipids and Strengthen Skin Barrier Function
By: In-Young Kim, PhD; Sayaka Nakagawa; Kinka Ri, …
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.

Palm-derived Dihydroxystearic Acid for Sensory and Technical Applications
By: Rosnah Ismail and Hazimah A. Hassan, Malaysian…
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.

ECM-derived Tetrapeptide to Counterbalance ECM Degeneration
By: Mike Farwick, Ursula Maczkiewitz, Peter Lersch…
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.

Orthorhombic Phase Stabilization for Internal Occlusion: A New Mechanism for Skin Moisturization
By: Johann W. Wiechers, PhD, JW Solutions
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.
