If you have your makeup bag on hand, then use…A concealer A creamy concealer is one of your best options, says Romy Soleimani, beauty director at large at Beauty.com. “Make sure not to use a brush to buff in the product because this will further aggravate the skin,” she says. “Gently press the concealer into the flaky areas, using your finger or a sponge until the product is absorbed and well-blended.” She suggests trying RMS’s “Un” Cover-Up ($36, rmsbeauty.com), a lightweight concealer rich in jojoba and coconut oil.  A tinted moisturizer or primer Tinted moisturizers or BB/CC creams and primers mask flakes in a pinch. Opt for a product with hydrating hylauronic acid and vitamin E to soften skin, says Soleimani. Pat a small amount onto the flaky area—rubbing will worsen the flakes.

Water and paper towels But in a real pinch, you can reach for good old paper towels and water to tame unruly skin. “Dab some lukewarm water on the flaky area and gently stipple your skin with a paper towel,” says Amanda Sanzone, a NYC medical aesthetician at Dr. Matthew Schulman Plastic Surgery. Don’t rub the skin, as that will only make the area more noticeable. Following this method should buy you a couple of hours, she adds. “When you get home, you should cleanse your skin with a moisturizing wash and follow up with a hydrating serum like Dr. Schulman’s Nourish [$80, msmdskintherapy.com],” she says.  If you’ve got nothing but purse essentials, then use… Hand cream Use this option only if you carry a hand cream made for sensitive skin: “Not all hand and body products are suitable for the more delicate skin on our faces,” Solemani says. She says she keeps Weleda Skin Food ($15, drugstore.com) in her bag at all times. “It works as a hand cream, but the natural and soothing ingredients make it safe to use on dry patches anywhere,” she says.  Lip gloss or balm “If it’s all you have, a clear gloss can save the day by dissolving flakes—as long as you use a very small amount,” Soleimani says. Just be sure to choose a gloss without menthol, which can cause irritation and watery eyes. Multipurpose lip balms will also get the job done, according to Sanzone, who says a small dab of classic Aquaphor Lip Repair ($5, cvs.com) will help reduce the appearance of flakiness while the clear formula keeps makeup in shape.
