The benefit of using color correctors was explained to Byrdie by makeup expert, Lauren Lebowitz, who said, "Opposite colors on top of one another will cancel each other out," making colored concealers ideal for helping to hide blemishes that regular concealer is unable to cover.
For example, makeup artist and YouTuber Emily Berry uses orange-toned concealer to cover dark blue or purple circles under eyes, and the results are jaw-dropping.
As per Foreo, orange is an opposite tone to blue, which means that it can work well to cover dark circles under the eyes. The orange hue will help to conceal the undertones of the darker areas. For darker skin tones, orange concealer tends to work well, but it may be too dark for lighter skin tones, so it's best to use a peach color corrector instead. A peach concealer includes red, orange, and yellow hues, and works in the same way to mask blue, green, and purple tones.
