While concealers are available that cover tattoos, spots, blemishes, scars, redness, and bruises, most people use a concealer to lighten dark circles under the eyes. Different concealers and correctors are formulated for each specific use. Pick a concealer and, when needed, a corrector designed for each of your problem areas. Under-eye concealers are not formulated for use on blemishes or areas of redness. They are creamier in consistency and lighter than the skin tone. Using under-eye concealer on areas of redness will only highlight the imperfections. Yellow-toned foundation that matches the skin tone is the best way to adequately cover blemishes, scars, and tattoos.
The application of under-eye concealer is the most important step in any makeup routine. Concealer is the one product that, when chosen and applied correctly, can instantly lift and brighten the face. Choose a color one to two shades lighter than the foundation. The skin under the eye is very thin, so the blue of the fine veins just under the surface tend to show through. A light yellow-toned concealer masks this blue discoloration and brightens the skin. For those with alabaster skin, a porcelain-toned concealer will work. Sometimes a stick foundation one or two shades lighter than the face can serve as an under-eye concealer for those who need very little coverage.
Correctors are available for extreme under-eye darkness. When a regular concealer cannot fully lighten the under-eye area, a peach or pink corrector is used to counter the purple or green tone. A regular yellow-toned concealer is usually lightly layered over the corrector to lighten the under-eye area. Occasionally, those with extremely deep purple or green coloration under the eye will not need the layer of regular concealer.
