1. A Collagen-Rich Korean Sheet Mask: Mediheal Collagen Essential Masks. This sheet mask, from iconic Korean brand, Mediheal, is infused with hydrolyzed collagen and elastin, both of which help improve your skin's texture, make it appear more radiant, and soften dry patches. Apply the mask, leave it on for 10 to 15 minutes, then remove it and gently pat the remaining essence into your skin. As a major bonus, it comes in a pack of 10, so you'll be stocked for ages.

According to one reviewer: "I popped these in the fridge to get them nice and cool for use after my shower and oh, I am so in love with them. They felt wonderful on-- cooling without being minty, moist without sliding off and lots of product to soak into my skin."
