In this article, several methods to quantify the protein collected by tape stripping are described, including traditional gravimetric methods as well as novel colorimetric and visible spectroscopic techniques. Further, one colorimetric method is described to effectively determine the keratolytic efficacy of various materials in vivo, suggesting additional roles for this method.

As the mechanisms of skin aging become better understood, their complexity commands a different approach for antiaging benefits—i.e., integrating multiple complementary actives into a single formulation. In the present article, the authors describe a comprehensive formula designed to effectively address sixteen different mechanisms of skin aging.

It often is claimed, particularly in East Asia, that Asian skin is more sensitive than Black or Caucasian. To explore this claim, the author investigates the current literature in this review and concludes there are two aspects being overlooked: the skin’s capability to cope with perturbations and the route of penetration.
