Formulating with Surfactant Silicones
By: Anthony J. O’Lenick, Jr., Siltech LLC, and Kev…
The authors describe how the use of amphiphilic silicones or surfactant silicones has allowed formulators to efficiently incorporate silicone polymers into personal care products. These materials act by lowering the surface tension in the oil phase of a formulation, allowing for easier spreading on skin and hair.

Oral and Topical Echium Oil for Skin Benefits
By: Bhaven Chavan, PhD, and Graham Pennick, Croda …
In the present article, the oral administration of echium oil is shown to increase collagen levels in the skin as well as barrier functioning and skin conductance. When applied topically, the oil increases dermal structural proteins, which results in a reduction in fine lines and wrinkles, and inhibits UV-induced inflammation.

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.
