Our vitamin C patch currently contains hyaluronic acid, vitamin C, and collagen. It can enhance skin firmness, improve fine lines and sagging. The application method is very simple: 1. Clean the eye area and gently pat it dry. 2. Remove the eye concealer and apply it to the contour of the eyes. 3. Gently press the edges of the patch with your fingers to ensure it is tightly adhered to the skin without any bubbles. The combination of hyaluronic acid and collagen provides deep nourishment and moisture to the eye area skin. Vitamin C effectively improves dullness, reduces dark circles, and makes the eye skin radiant.
