SkinBetter Lines 1oz Used a few pumps and found out my skin didn't like. .................................... A no-needle, hyaluronic acid solution that improves the appearance of deep expression lines and wrinkles. Why You'll Love It: Improves the appearance of deep expression lines. All skinbetter science products are dermatologist tested, paraben free, fragrance free, dye free, and cruelty free. 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-office treatments. InterFuse is a patented technology that aids in the delivery of previously difficult-to-deliver ingredients for targeted and noticeable results.
