With passing time, the fibroblast celles located at the base of deep wrinkles produce up to 3 times less collagen than the other fibroblasts. Thanks to an exclusive combination of 3 cutting edge active ingredients (extracts of Alkekengi's calyx, Soya and Padina Pavonica ) Sisleÿa Daily Line Reducer helps reconstruct the skin's framework spectacularly: 1. by preserving the dermis fibres which make up the density, the elasticity and the resistance of the skin (anti-collagenase and anti-elastase effects). 2. by stimulating the neo-synthesis of collagen in order to densify the support tissue, as well as the glycosaminoglycanes which reinforce the hydra-cushion. How to use: Apply 3 drops morning and night to the face and neck. Use on its on or under a skincare cream. 1.08 oz This item is not available for international shipment.
