Primers are a makeup must for their ability to boost the staying power and longevity of any products you apply on top, and they can also be yet another way to get an extra boost of moisture into your skin: "When your skin is dry, you need to up the ante by making sure that every product you use is hydrating and combatting that dryness," explains Sotomayor. Point being, seek out a primer that specifically says it's moisturizing.

Sotomayor uses La Mer The Perfecting Treatment, $240, which has the added benefit of a slightly pearlescent finish, a nice option when you're trying to create radiant skin, he adds. The one caveat: If you're trying to also conceal fine lines or wrinkles, opt for a hydrating formula without any added luminescence, since it may accentuate what you're trying to hide. In that case, a plain moisturizing formula, like e.l.f Hydrating Face Primer, $6, is perfect. Either way, avoid anything that's mattifying or shine-stopping (and a lot of primers are), as that's the last thing you want for your dry complexion.

"Most foundations are made for women with normal skin and are geared more towards being long-wearing than moisturizing," explains Sotomayor. First and foremost, stick with liquid or cream formulas and pass on powders. Then, look for ones labeled as moisturizing or hydrating (steer clear of those made for oily or combination skin, as they'll have the opposite effect, he cautions).

While the level of coverage doesn't necessarily make a difference, the finish does; since dry skin already looks matte, choose products that have a luminous, rather than matte, finish, advises Sotomayor. Two that fit the bill: The new Merle Norman Timeless Illuminating Makeup Broad Spectrum SPF 30, $28 and Becca Aqua Luminous Perfecting Foundation, $44.

Picking the right foundation is sups important, but how you apply it can also make a difference if you're dealing with dry skin. The best tool for the job? A synthetic foundation brush, like the Makeup Revolution Ultra Metals Contour Foundation Brush, $14.99. "When you apply foundation with your fingertips, they end up absorbing some of the moisture. You want all of that moisture going into your face, not into your hand," explains Sotomayor.

Since you're likely just dabbing a tiny bit of concealer on your complexion, as long as you're not using any kind of powder formula, you should be fine. But while many people can get away with using the same concealer on their complexion and under the eyes, anyone with dry skin should invest in two separate products, advises Sotomayor. "The skin under your eyes tends to the be driest on the entire face, so you want to find an extra hydrating, creamy concealer for this purpose," he says. He likes the Nars Radiant Creamy Concealer, $30.

No matter how well-hydrated your skin may look at this point, a touch of luminizer is a non-negotiable when the goal is a dewy, gorgeously glowy complexion. Pass on powders (shocker), which can end up looking flat and chalky, says Sotomayor. (And after you've just gone through all these steps to create the opposite effect, that's the last thing you want!). Liquids, like Sotomayor's go-to, Maybelline New York FaceStudio Master Strobing Liquid Illuminating Highlighter, $9.99 are a much better option. Or, opt for a cream, which melts seamlessly into skin for that lit-from-within look we all want. Try: RMS Beauty Champagne Rose Luminizer, $38.
