Ben Nye Concealer Crayons are corrective colors that make the greatest cover-up jobs as easy as 1-2-3. Apply the concealer crayon directly on top of the area to be concealed. Pro Tip: Make sure the proper color is chosen for your correcting needs. Colors opposite of each other on the color wheel are used for color correcting. Correct redness around the face and eyes with the Red Neutralizer options and warm up dark blue shadows with the Blue Neutralizers. Conceal tattoos by tracing over the dark lines of the tattoo with either tattoo neutralizing shades. Gently wipe off makeup with Quick Cleanse or a makeup remover of your choice. Wash off residue with soap and water, oil-free Hydra Cleanse or a facial wipe.
