• Surface topography effectively mimics human skin, so products spread naturally during application.
• Similar pH, critical surface tension, and ionic strength as human skin, so emulsions break the same as on human skin.
• Optimized components, with excellent consistency lot-to-lot, insure reproducible effects.
• More reproducible results compared to human skin.
• Low lot-to-lot variability means more comparable results study-to-study.
• Individually heat-sealed single sheet packaging means immediate availability of fresh material with less waste.
• Always available for testing. No more scheduling your testing around your human test subjects’ availabilities.

Synopsis

In the last few years, the desire to acquire a tan without sunbathing has grown. In response, many cosmetic companies have produced self-tanning preparations. However, to optimize these formulations, a suitable model to assess the colour induced on the skin remains to be developed. We have developed an in vitro method using a synthetic skin in order to study the efficacy of self-tanning formulations. The in vitro test was then used to study the influence of cosmetic ingredients upon the colour induced by erythrulose- or dihydroxyacetone-containing formulations. Finally, an in vivo study allowed us to relate the results obtained in vitro with those found on human skin. The results show that this in vitro test system is a reliable tool to predict the efficacy of self-tanning products.

Several methods exist that evaluate sunscreens efficacy for ultraviolet radiations (FDA, DIN, COLIPA, Australian standards etc.) and it is generally accepted that the determination of sun protection faction (SPF) on humans is the most reliable one.

SPECTROSCOPY OF SUNSCREEN PRODUCTS: HOW TO EXPLAIN THE SPECIAL SHAPE OF UV CURVES OBTAINED FROM IN VITRO SPF TESTS.
Authors: L. Ferrero, A.M. Orcet, L. Zastrow

INTRODUCTION:
Numerous attempts have been made to understand how sunscreen preparations protect against UV radiations (1)-(4). Normally, the final UV absorption of a sunscreen product should depend on absorption curves of each UV filters placed within the preparation. However, it is now trivial to remark the bad accordance between SPF(s) directly calculated from spectroscopic absorbances of pure UV filters (obtained from dilute solutions and measured in 1 cm quartz

INTRODUCTION:
The use of polymeric additives as raw materials 1, 2, 3, 4, which could increase the SPF value of sunscreens, has grown up much lately.
