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.

Evaluating Water Permeability and Occlusion in Wound Dressings and Topical Cosmetics
By: Hongbo Zhai, MD, and Howard I. Maibach, MD, Un…
The present study uses an evaporimeter to measure the degree of water loss from in vitro skin samples covered by occlusive and semi-occlusive wound dressings to serve as a model for determining the effectiveness of occlusive cosmetic formulations. The purpose of this work was to develop a model for determining the effectiveness of occlusive cosmetic formulations.
