This heavy-hitting Make Up For Ever Full Cover Concealer ($34) can cover blemishes along with scars and tattoos (on face or body) because there's an emulsion of oils and cellulose powder working together to evenly spread pigments and lock them into skin. It also holds up thanks to a layer of water resistance (from plastic polymers inside), and has earned more than 3,000 5-star reviews from other Sephora shoppers.
