Identify your skin undertone: cool, warm, or neutral
Match concealer to your foundation for blemishes and spot coverage
Choose one shade lighter than your foundation for under-eye brightening
Use a peach or orange corrector for dark under-eye circles on deeper skin tones
Use a yellow or peach-toned concealer for blue or purple under-eye discoloration
Use a green corrector for redness or blemishes
Test shades in natural light
Swatch on the jawline or under the eyes, not on the hand
Check how the shade looks after it dries
Choose a formula that matches your skin type and coverage needs
Pick a shade that blends seamlessly into your skin for spot concealing
Avoid going too light under the eyes to prevent a gray cast
Adjust shade seasonally if your skin tone changes
Consider the finish: matte, satin, or dewy
Use two concealers if needed: one for correcting and one for brightening
