The Vino-concentrate Refining Serum combines Niacinamide and Tripeptides to provide multiple benefits for the skin. Niacinamide helps improve the appearance of various skin concerns such as enlarged pores, uneven tone, fine lines, dullness, and weakened skin. Tripeptides stimulate the production of Collagen and Elastin, resulting in firmer and smoother skin with reduced fine lines and wrinkles.
