R&D& Matarromera’s department has devoted several years of research to devising its own patented process for extracting polyphenols from grape skins, the end product of which is Eminol®, a certified natural antioxidant which has been independently endorsed for its high antioxidant capacity which helps to slow the ageing process. The first application that the Matarromera Group developed from Eminol® was ESDOR COSMETICS, a line of high-end cosmetics products supported by the Institut d’Expertise Clinique Espagne, one of the world’s leading cosmetics sector centres.

The ESDOR cosmetics line is made with a minimum of 85% natural components, the most notable of these being polyphenols extracted from red Duero Valley grapes.
