A Dermatological View—In vitro Buffering Capacity of Human Skin Layers

Previous studies demonstrate that skin buffering capacity can be measured in vitro by applying several concentrations of hydrogen chloride (HCl) and sodium hydroxide (NaOH) on skin and evaluating the pH change pre- and post-dosing. Here, the authors employed this technique to evaluate the buffering capacity of skin layers including intact SC, denuded SC and dermis skin samples.

Research Reveals New Stratum Corneum Structure

Researchers in Sweden have described a new structure and function of the stratum corneum at a molecular level, providing for a deeper understanding of skin diseases as well as the potential for large scale delivery via the skin.

Consumer Perspective—Skin Types and Sensory Experience

Sophisticated texture and fragrance as part of a formulation’s aesthetics are important to the discerning consumer, and skin type is the primary influence behind how the consumer perceives a skin care product. For example, consumers with dry skin require a richer moisturizer, even though the product should absorb quickly for a smooth finish.
