Locks in Moisture
It's an effective moisture barrier for at night, but I don't think it does anything but seal in moisture because I know that collagen is too big of a molecule to pass through the skin's barrier. Still super cute and great for dry skin that needs help helping itself. If your skin is so dry that it's flaking off, sleep with this on and it won't be when you wake up. However, don't put it too close to your eyes because they will water a bit.
