Although cellulite is not considered a disease, it is a significant cosmetic problem for many post-adolescent women. Recent studies using new diagnostic techniques such as ultrasound imaging can define the cellulite-reducing efficacy of cosmetics. However, there is still a need to standardize and objectify the testing procedures and to find parameters to measure anti-cellulite efficacy.

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.

A sunscreen layer’s thickness is critical to its SPF. However, current regulations specify a mass application rate for testing, rather than a volumetric application rate. This significantly underrates the SPF values of mineral sunscreens due to their higher densities since, compared with their relative organic counterparts, thinner films are being tested, as will be shown here.

Genomics assists product developers in understanding the expression of specific genes and their relationship to particular skin attributes. This article reviews commonly used testing techniques, such as DNA microarray, RT-PCR, SAGE, northern blot and RNA sequencing, and describes their application in testing the effects of cosmetic ingredients and products on skin.
