Facial Care

We are experts in the tolerance and efficacy assessment of cosmetic products for facial care, cleansing and treatment. We carry out anti-ageing, anti-photo ageing, firming and sebum regulator studies, among others.

Our extensive volunteer data base allows us to select and define the most suitable panel for each study. Moreover, our facial efficacy studies are backed by photographic material which offers our clients images with greater visual impact and added value, which can be put to good use by their marketing departments.

We make a difference by designing studies to meet our clients’ needs, in compliance with high quality standards and in accordance with the principles of Good Clinical Practice (GCP) and Good Laboratory Practice (GLP).
