Dermablend Cover Care Full Coverage Concealer ($28) is a 24-hour hydrating concealer that's designed to cover blemishes, discoloration, and dark circles in one swipe. (It has also been tested on post-injection and surgery bruises and covers them like a dream.) It has a lightweight, creamy texture that blends seamlessly into skin with a matte finish. The formula is vegan, sensitive skin and allergy tested, and waterproof — so much so that after I tested the shades on my hand and went to wash them off under warm water, they stayed put.
