The Syngeristic Anti-irritant Effects of (-)-α-Bisabolol and Ginger

Damaged skin often is associated with increased levels of interleukin-1 (IL-1) and/or prostaglandin E2 (PGE2). In the present study, researchers combined (-)-α-bisabolol, a potent IL-1α inhibitor, with ginger extract, an efficient PGE2 inhibitor. The synergistic anti-irritant efficacy of this mixture was shown in vivo on detergent-induced erythema.

Assessing the Safety of Parabens: Percutaneous Penetration and Risk Analysis

In cosmetics, parabens are widely used due to their low cost and efficacy. In recent years, however, some reports have claimed that these materials exhibit estrogenic activity, which has led to attempts to replace them in formulations. This article reviews penetration studies of parabens spanning the past 20 years to determine whether they pose a risk to human health.

Interpretation of SPF In vivo Results: Analysis and Statistical Explanation

Methods for determining SPF in vivo are based on a biological response by human skin. To overcome intrinsic variation in these methods, large numbers of volunteers and statistics are required; however, these concepts are often poorly understood or worse, misinterpreted. This article discusses how these values should be interpreted and explains what they mean to formulators.

Alternatives to Animal Testing: A Review of Trends and Perspectives

Alternative test methods have the potential to reduce animal testing; however, the extent to which in vitro methods can be replaced is questionable. This article summarizes validated alternatives to test the safety of cosmetic ingredients. It also illustrates how great a challenge it is to devise a proper alternative method.
