Get an immediate firming & smoothing effect for up to 8 hours with the Nuxe Merveillance Expert Lift & Firm Serum, a lifting formula that targets visible lines. Created for women of all skin types, this silky formula targets the three proteins that help to retain skin's youthful beauty: Vimentin, Collagen & Elastin. As skin matures, these proteins are inhibited by the process of glycation & their functioning slows down, resulting in a loss of firmness & wrinkles. The Merveillance Expert Serum prevents this process with Daylily extract (3 patents pending), both removing sugars from the three key proteins & preventing them from altering the proteins in the future. Day after day, visible lines are filled in & the skin feels firmer. The ultra silky texture of the serum makes its application a tactile experience, leaving a satin fresh finish. A discreet fragrance of ylang, jasmine & soft vanilla provides added pleasure. Apply morning & night to clean skin, & follow with the Merveillance Expert Cream or Night Cream. Paraben-free, non-comedogenic.
