WHAT IT DOES Advanced Génifique hydrating serum improves elasticity and improves the appearance of fine lines caused by dehydration or due to thinning skin, which can eventually deepen into wrinkles. Used morning and night, this hydrating serum visibly hydrates, plumps and evens tone to restore healthy, younger-looking skin in just 7 days*. WHAT IS THE SKIN’S MOISTURE BARRIER? “The skin barrier is the outer surface of the skin. It acts as a powerful shield to help protect against external aggressors. It works to keep the good stuff in and the bad stuff out. When your skin barrier’s natural balance is compromised is can leave your skin more vulnerable and more sensitive.” – Dr. Annie Black, Lancôme International Scientific Director
