Dermablend is the leader in corrective and skin covering makeup. It's used to cover up all types of skin problems ranging from covering scars, varicose veins, and even stretch marks. The Leg and Body Cover Crème ($18) is especially excellent at covering up tattoos. Apply a thin layer and blend with a foundation brush. Then, set it with a loose powder. It's meant to last up to 16 hours, so you don't have to worry about your tattoos showing up like an uninvited guest halfway through you wedding!
