The cosmetic product used to cover dark circles under the eyes is concealer.
Concealer is a pigmented makeup product designed to mask or reduce the appearance of dark circles, blemishes, scars, redness, and uneven pigmentation. It is usually more heavily pigmented than foundation, which is primarily used to even out overall skin tone. Concealer can be applied with a brush, sponge, or fingertips and blended into the surrounding skin.
Different formulas suit different purposes. Liquid concealers are versatile and commonly used under the eyes, while cream and stick versions often provide heavier coverage for spots or discoloration. Color-correcting shades can help neutralize particular tones: yellow may soften purple or blue-looking circles, while peach and orange tones are often used against bluish shadows, depending on the wearer’s skin tone.
Concealer is sometimes confused with primer or powder. Primer prepares the skin and can improve makeup wear, while powder helps set makeup and reduce shine. Foundation provides broader, more even coverage; concealer is generally targeted to smaller areas.
The first commercially available concealer is widely credited to Max Factor’s Erace, launched in 1954. Modern concealers range from sheer products to camouflage makeup designed for pronounced discoloration.
