If you dream of waking up to perfectly glossy, glistening skin, this is your sign to try slugging! Your moisturiser might cover your hydration goals for the day, but at night, you gotta layer it up. The trick is to use hyaluronic acid or ceramides and then lock in the moisture with an occlusive agent such as petroleum jelly. P.S. If your skin is oily or acne-prone, skip slugging and stick to regular moisturisers instead.
