Cocoa butter is a high in fatty acids, which is why it’s not often touted for its ability to hydrate, nourish, and improve elasticity of the skin. The fat in cocoa butter forms a protective barrier over the skin to hold moisture. Cocoa butter is also rich in natural plant compounds which may improve blood flow to the skin and slow skin aging by protecting against damage from sun’s harmful UV rays. One common use of cocoa butter is to smooth scars, wrinkles, and other marks on the skin.
