Today, product formulation goes hand in hand with efficacy testing, but nearly 40 years ago, when Sergio Nacht, PhD, started out in the personal care industry, it was a different story. Throughout his decades in personal care, Nacht has developed methodologies that have allowed the personal care industry to establish efficacy of a product and convey this to the consumer. He has also been instrumental in the increased efficacy of personal care products through sustained release.

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.
