Our Vitamin C eye patches contain hyaluronic acid, vitamin C, and collagen. They can enhance skin firmness, improve fine lines and sagging. The usage is very simple: 1. Clean the eye area and pat dry. 2. Remove the eye mask and fit it along the contour of the eyes. 3. Gently press the edges of the patch with your finger, ensuring that it adheres closely to the skin without bubbles. The combination of hyaluronic acid and collagen provides deep nourishment and hydration for the skin around the eyes. Vitamin C effectively improves dullness, reduces dark circles, and makes the skin around the eyes look radiant.
