| Résumé : |
With Lys'IastineTM V, we present an anti-ageing active that targets the cellular senescence of fibroblasts. In vitro, 0.025% Lys'lastine V significantly reduced the accumulation of progerin, the "ageing protein" that is linked to replicative senescence in fibroblasts (-54 %). Furthermore, 0.05 % Lys'lastine V significantly increased levels of the "youth protein" Klotho (+34%), while 1 % Lyslastine V re-induced expression of lysyl oxidase-like (LOXL) in reconstructed dermis (MimedermTM) (+64%) and increased levels of LOXL in a reconstructed skin model (MimeskinTm). LOXL is the cross-Iinking agent responsible for the deposit of tropoelastin on microfibrils and therefore the synthesis of functional elastic fibers in the dermis — but from the age of 18, it decreases rapidly. By re-inducing LOXL, this BASF active helps restore the skin's elasticity, ln a clinical study, Lys'lastine V was proven to significantly improve the skin's suppleness, both on the face and décolleté. |
