Choose the right formula
Because the skin around your eyes is much more delicate than the rest of your face, you’ll want to find two different concealer formulas: one for under-eye circles and another for acne blemishes, scars, and rosacea. For the under-eye area, choose an oil-based liquid or cream formula. For other blemishes, choose an opaque formula you can apply with a pointed brush. These makeup tricks can help you fake flawless skin.
Find the perfect shade
Choosing a shade that is too dark is the most common faux pas, says celebrity makeup artist Mario Dedivanovic on Total Beauty. “When the concealer is too dark, setting it with powder will only make it darker, which makes the spot you’re trying to cover look like a muddy patch of skin,” he says. That said, you’ll also want to choose a formula with an undertone that supports the type of color correction you need. Use color theory as your guide; colors that sit opposite each other on the color wheel cancel each other out. For example, use a formula with yellow undertones to neutralize bluish under-eye circles; one with peachy undertones to neutralize brown or yellow circles; and a green-based formula to counteract redness.
