Antiaging in a Different Light: Assessing How Chromophores Color Perception
By: Philippe Mondon, Nada André, Emmanuel Doridot,…
Aging influences cutaneous parameters that give rise to progressive changes in three skin chromophores, altering the visual homogeneity of skin. To address these changes, the authors developed and examined the effects of a complex based on Siegesbeckia orientalis and Rabdosia rubescens using a novel skin imaging technique.

Evaluating Essential Oils in Cosmetics: Antioxidant Capacity and Functionality
By: P. Ziosi, S. Manfredini, S. Vertuani, V. Rusce…
In the present work, the antioxidant capacities of three essential oils derived from basil and thyme were evaluated using a photochemiluminescence (PCL)-based assay. In addition, since the base formulation can affect the antioxidant activity of oils contained therein, ingredient interactions within final formulations were investigated.

Is Cosmetic Science Really "Bad"? Part IV: How Scientific is Cosmetic Science?
By: Johann W. Wiechers, PhD, JW Solutions
Six questions from Michael Shermer’s Baloney Detection Kit have been discussed in this series. The results were not flattering for cosmetic science (read: cosmetic scientists) but cosmetic science did not score badly on all points. Questions seven and eight, described here, discriminate true science from borderland science and non-science or nonsense.

Translating Data into Claims and Interpreting Regulations: Science vs. Marketing
By: Nava Dayan, PhD, Lipo Chemicals
Substantial evidence, which the FDA requires to support claims for drugs, is applicable to personal care, especially considering the pharmaceutical direction products have taken. The present article considers whether the industry is benefiting from marketing without assuming the responsibility for potential effects. In addition, it considers the limitations of in vitro and in vivo test models.

A Rapid and Sensitive In vitro Method to Ascertain Antioxidative Capacity*
By: Hongbo Zhai, MD, and Howard I. Maibach, MD, Un…
New methodologies have recently been developed to determine antioxidant effects but they often require extensive training and are time-consuming to conduct. In the present article, however, the authors describe an in vitro method to detect the effects of antioxidant-containing formulations using photochemiluminescence to provide rapid, accurate and sensitive measurements.
