Camouflage Dark Circles
You might have noticed that applying concealer that's a few shades too light to cover up the effects of a late night (or two...or three) gives the appearance of reverse raccoon eyes. For a natural-looking solution, try a brightening concealer to reflect light instead, says makeup artist Carmindy. If you're fair, look for a pink shade; if you're medium to dark, opt for an apricot color. (Try Sally Hansen Natural Beauty Fast Fix Concealer, $9.) Instead of using your fingers to apply (which Carmindy says can tug on delicate skin), you'll have more success using a synthetic brush to sweep the brightening concealer under your eyes and up into the inner corners, which are prone to shadows.
Camouflage Dehydrated Skin
If your face is especially dry—thanks to cold weather or an overheated office—your first instinct might be to slather on the richest and heaviest cream you can find, but applying makeup over that can be tricky. Save the thick stuff for bedtime and try makeup artist Mally Roncal's quick fix to help hydrate pre-party: Rub an oil-free moisturizer onto clean skin and layer a luminizing primer on top (try Mally's Perfect Prep Poreless Illuminating Primer, $35).
Roncal suggests applying a yellow-based concealer down the sides of your nose, around your nostrils, on the outer corners of your eyes (where many of us have hyperpigmentation) and over broken capillaries to cover up any redness or shadows. Then use a nonlatex sponge to apply a few pumps of liquid foundation all over your face (including the undereye area and your eyelids) to even out skin tone, says Carmindy.
