Our eye serum contains Hyaluronic acid, collagen, and chestnut tree extract. It can improve the fine lines and wrinkles around the eyes and improve the smoothness of the eyes. Collagen enhances eye elasticity and tightens eyes. Its application method is very simple: 1. Clean the skin around the eyes and gently dry it. 2. Apply proper amount of serum evenly around eyes. 3. Relax facial muscles for 60 seconds and massage in a circular motion to promote absorption. Sodium hyaluronate locks in moisture and prevents dry skin.
