L'Oréal Paris Youth Code Skin Activating Ferment Pre-Essence Serum strengthens the skin's barrier and enhances cell renewal to improve the overall quality of the skin for a radiant, youthful complexion. With age, skin regeneration slows down making the skin more vulnerable to external aggressors. Skin gets dryer and fine lines become visible.

For the first time, L'Oreal Paris has developed a pure and highly concentrated ferment serum thanks to ultrasonic extracting techniques. Drop by drop, this serum stimulates skin's cell-renewal and activates its youth from within. Skin is left refined, bouncy and resilient.
