Facial anti‐wrinkle cream: influence of product presentation on effectiveness: a randomized and controlled study

Abstract

The present study conducted as a formal trial could not verify a claim of anti-wrinkle effect of a known prestigious product. Surprisingly, there was no systematic effect on subjective and objective cosmetic parameters of the luxury packaging, except a better compliance. Product appreciation by consumers may, however, be different in spontaneous use not biased by study conditions.
