Patented, state-of-the-art technology features high-molecular-weight, injectable-grade hyaluronic acid for the improvement in the appearance of deep expression lines. Four additional types of hyaluronic acids of varying molecular weights work to bind water to the surface of the skin to improve moisture retention to smooth the appearance of lines and wrinkles. Peptides help expression lines appear smoother upon application. A collagen complex made up of amino acids, peptides and Vitamin C work synergistically to support the skin. This targeted formula helps reduce the look of deep wrinkles and expression lines and is complementary to in-clinic treatments. All skinbetter science products are dermatologically tested, paraben-free, fragrance-free, dye-free, and cruelty-free.
