Green concealer is a color-correcting product that can help neutralize redness on the skin caused by conditions like rosacea or acne. Green concealer works by using color theory: green falls directly opposite from red on the color wheel, so green can help neutralize any unwanted red blemishes or blotchy-ness. Green concealers are typically sheer, so they won’t leave your skin with a greenish tint, or remain visible under any makeup you plan to wear.

Green concealer can be used to address various types of skin redness, including breakouts and inflammation caused by acne, broken blood vessels, and areas of red skin caused by rosacea. To apply green concealer, start with a clean face and follow your usual skincare routine. Then, apply the green concealer before foundation and concealer. Simply apply the green color-correcting product to the red area after foundation, and then put a regular concealer on top.
