Sunscreens, an emulsion of several phases, are used as UV filters in order to protect people from sun damages. Filters can be divided in two types: the chemical ones which are organic molecules that absorb selectively ultraviolet light and the physical ones (such as TiO2) which are inorganic particles that scatter and may absorb some of the UV radiation. The sunscreen quality is given by the sun protection factor (SPF), measured in vivo. In order to avoid long and complicated tests, a quick and simple in vitro method, using a plastic substrate, has been established, which gives an approximation of the SPF. In order to model the sunscreen protection, we had to evaluate the sunscreen distribution. We used an OCT (for Optical Coherence Tomogra...
