Face and Body Paint
Both Rudder and Stewart agree that an oil-based cleanser is the best way to remove face and body paint. Oil breaks down water-resistant formulas, so it will dissolve that Mystique costume with ease.
Stewart recommends starting by pairing a wipe with an oil-based formula like Make Up For Ever Extreme Cleanser ($32). Remove excess residue by getting in the shower and scrubbing down your body with shampoo and a loofah.
Skin still stained? Stewart swears by men's shaving cream. "Let it sit for five minutes, then use your loofah to wipe it off," she said. Though it sounds strange, shaving cream is actually a powerful stain remover. Learn how to use it to get foundation spills out of your clothes.
