Decorative cosmetics in testing

Decorative cosmetics primarily serve to change the external appearance in terms of increasing attractiveness. Products such as foundation, eyeliner and lipstick are intended to conceal specific minor blemishes or emphasize their advantages. We investigate the efficacy of these products through so-called “evaluator studies” in which clinical photos are taken before and after use with the test product. The corresponding image pairs are then rated by blinded and randomized evaluators for parameters such as “Radiant Appearance”, “Appeal” or “Even Appearance”.
