The skin around the eyes is the thinnest skin on the body and it has very few oil glands — which means it loses hydration faster than the rest of the face. That's why hydrogel eye patches can actually make a visible difference. They create a little moisture chamber that helps ingredients like hyaluronic acid and peptides stay in contact with the skin longer while also gently reducing puffiness. I went down a full skincare science rabbit hole learning how different molecular sizes of hyaluronic acid hydrate different layers of the skin and how peptides act like tiny biological signals telling skin cells to repair and was very impressed with the ingredient formulation of the Cosrx hydrogel collagen eye patches @COSRX Official skincare peptideskincare koreanskincare eyepatches cosrx LTKOver40 LTKmorningroutine LTKselfcare
