Abstract
The present invention relates to the field of cosmetic and dermopharmaceutical compositions. It concerns oligomer compounds of D-glucuronic acid or D-glucuronate with a β (1-4) sequence (or oligoglucuronans) containing a degree of acetylation specifically between 8.7±0.5 and 9.2±0.5% by weight of O—CO—CH3 group compared to the weight of glucuronic acid and with a degree of polymerisation (DP) of 18-19±2. The oligomer compounds according to the present invention are intended to stimulate the elasticity of the dermis and epidermis although they also act to increase dermo-epidermal cohesion in order to combat skin ageing, lines, wrinkles, visible and/or tactile skin discontinuities, loss of firmness, elasticity and tone and to combat skin tissue deformability. The invention also concerns a cosmetic composition containing at least one compound as recited according to the present invention.
