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.

Evaluating 1,3-Propanediol for Potential Skin Effects
By: Leigh A. Belcher, Carl F. Muska, PhD, and Jose…
In the present article, the authors assess the skin irritation and sensitization potential of 1,3-propanediol (INCI: Propanediol). Results in animals and humans by acute or repeat exposure support a low potential of skin reactivity for the material. In addition, the skin reactivity potential in humans was found to be lower with 1,3-propanediol than 1,2-propanediol (INCI: Propylene Glycol).

Predicting the Percutaneous Penetration of Cosmetic Ingredients
By: Sara Farahmand, PhD, University of Cincinnati …
While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.

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.
