Step 1: Moisturize, Moisturize, MoisturizeAt night, use a thick cream formulated for under the eye. During the day, apply a lighter cream before you apply makeup. This will help your corrector and concealer glide on more smoothly.
Step 2: Apply a CorrectorUnder-eye correctors are formulated for dark circles found under the eyes. They work by counteracting the purplish or blue circles under the eyes and they come in pink and peach shades. For best results, apply on a clean face. Dot the corrector at the corner of each inner eye and continue to "paint" the corrector under the eyes close to the lashes. Apply generously. Pat the corrector into the skin with the pad of your middle finger. Blend well.

Step 3: Apply a ConcealerAfter your corrector is applied, you'll want to use a yellow-based concealer. Dot the concealer under the eyes and use the "pat method" to press the product into the skin. When choosing a concealer, I recommend a shade lighter than your skin tone. If your circles are very dark, you can go 2 shades lighter. Make sure to blend well so you don't get a raccoon look.
Step 4: Foundation TimeNow you can apply your foundation to your face, hitting the areas that need it most. No need to cover the entire face in foundation.
Step 5: Set Makeup With a Yellow-Based PowderUse a yellow-based powder to set your makeup. If you have super fair skin, use a white powder to set the concealer.

If All Else Fails, Consider Laser TreatmentsIf you have a chronic case of under-eye circles, you could contact a doctor about lasers. Lasers can thicken the skin by increasing collagen production, so you are less likely to see veins, according to Los Angeles facialist Kate Somerville in InStyle magazine.
