Application of biophysical and skin imaging techniques to evaluate the film‐forming effect of cosmetic formulations

Abstract

Products with film‐forming effect, or ‘second skin’, which guarantees an immediate protective effect after application, is a highlight, especially when composed of natural ingredients. Thus, the objective of this study was to evaluate the immediate film‐forming effect on skin of a gel and emulsion formulations added with Kappaphycus alvarezii and Caesalpinia spinosa extracts through biophysical and skin imaging techniques, especially with the Reflectance Confocal Microscopy (RCM).
