Look for a tacky formula that contains a small percentage of salicylic acid like Clinique Acne Solutions Clearing Concealer ($17.50, sephora.com). This helps treat the pimple while covering it, so it's less noticeable when you wash off your makeup. Dot it on with a clean concealer brush (this minimizes the spread of bacteria), making sure to swipe across the blemish from all angles—side-to-side and up-and-down—to cover every curve.
Combat redness with a green tinted concealer like Essence Say No to Redness ($3, ulta.com). The opposing hue neutralizes any pink tones and goes undetected when worn under foundation. Swipe the stick along blotchy-prone areas—around the nose and mouth—then use a sponge (or your finger) to blend the color before layering on your usual base.
Cover and help soften lines using a formula that contains vitamin C, like Tarte Maracuja Creaseless Concealer ($25, sephora.com), which helps firm skin and fight free radicals that can cause more wrinkling. This one also packs maracuja oil to help glide over the creases. After foundation, use a concealer brush to smooth over problem spots like crows feet and eyebrow furrows.
To conceal purple and blue under-eye circles, opt for a creamy, dense formula with a yellow or orange tint. For yellow, try NYX Concealer in a Jar in Yellow ($5, ulta.com) and for orange, try MAC Studio Finish Skin Corrector in Pure Orange ($14, maccosmetics.com). Use the concealer to create a downward pointing triangle under your eyes, with the point ending right in the middle of the apple of your cheeks. Blend it completely (you can go outside the triangle), and then apply your foundation.
A formula with light-reflecting particles and a hint of pink, like Benefit Ooh La Lift Instant Under-Eye Brightening Boost ($22, ulta.com) will brighten up skin for a luminous glow. Use it under your eyes—or use it as a highlighter and apply it to the high points of the face (the bridge of your nose, the tops of your cheeks, and above your top lip) before makeup for a softer finish or after for a more dramatic sheen.
Help prevent future brown spots from forming (and existing ones from darkening) by wearing (and reapplying) sunscreen. To take care of the ones you have, use a formula with vitamin C, like Maybelline Instant Age Rewind Eraser ($7, drugstore.com) to brighten those areas while they’re temporarily concealed. Twist the top until the liquid comes out, then use the sponge to blend it over spots.
