Using red lipstick in place of concealer is an age-old under-eye concealer hack. But does it really work? According to celebrity makeup artist Stephanie Flor, the logic behind it is sound.

"Using red lipstick under the eyes is one of the oldest tricks in the book -- I learned it when I was in my teens," she says. "The whole idea is that a tiny bit of red placed on a certain area will cancel out the blue." Neutralizing the blue or purple color allows you to apply your concealer on top without the dark circle coming through.

"Does it work? Yes," says Flor. "But with so many great products out there, why take a chance trying to find the right red lipstick to correct your under-eye circles?"

If all you've got with you is some red lipstick, go for it. But for best results, try Make Up For Ever 5 Camouflage Cream Palette for Dark Complexions, $40.

In the same way orange counteracts blues and purples, green balances out redness.

To minimize acne spots and red tones, Flor recommends using a green skin corrector, such as NYX Cosmetics Concealer Jar in Green, $4.99, applied with a sponge or angled foundation brush.

Follow up with foundation and a heavier coverage concealer (try Kat Von D Lock-It Tattoo Concealer, $25) to finish camouflaging any blemishes.

Hypopigmentation got you down? We're talking about those little white spots that appear on the skin due to loss of pigment from too much sun.

Though there's no cure for hypopigmentation, the pros say you can conceal them by repurposing products you already have.

"Using a taupe or brown eyeliner, or a brown brow pencil, is a good trick for hiding white spots," says Stiles. "The pencil will stick to the skin more precisely than using a concealer and will allow you to really paint within the lines."

Try using Mineral Fusion Eye Pencil in Rough, $15, or Anastasia Brow Wiz, $21, before blending with concealer and setting with powder.

An easy way to work color correction into your makeup routine is by opting for a color-correcting primer. "I like to use primers to help me create a balanced base to work from," says Flor.

Try one of Clinique's Superprimer Face Primers, $27, which correct issues like redness, discoloration and dullness in darker complexions, while prepping skin for makeup application and all-day wear.

To counteract hyperpigmentation and melasma, makeup artist Shonagh Scott suggests investing in a professional camouflage palette, such as Kryolan Dermacolor Camouflage Creme Palette 12 Colors, $54.50. Even the severest discoloration is no match for this stuff.

To apply, Scott recommends using a concealer brush to paint a peachy color from the palette onto medium skin. For darker complexions, use a color with more orange in it.

Warm up some of the product on the back of your hand (this thins out the texture, making it easier to apply), then use your concealer brush to transfer the product from your hand to the problem areas on your face. Pat the product into your skin with your fingers to blend.

Once you've finished with your camouflage cream, Scott suggests using a dampened Beautyblender sponge to apply foundation over top (try Illamasqua Skin Base Foundation, $44). When applied with a stippling motion, the soft and supple sponge assures that you don't disturb the color cream underneath.

After foundation, continue applying your makeup as usual, and enjoy perfectly concealed skin.
