Frequently Asked Questions

Is it important to wear sunscreen under makeup, or is SPF makeup enough?

Dermatologists recommend wearing a separate face sunscreen under makeup since “people regularly apply less sunscreen when using an SPF-containing foundation, BB or CC cream,” says Jane Yoo, MD, a dual board-certified dermatologist and Mohs surgeon based in New York City. While the proper amount of sunscreen is about a teaspoon to the face and neck, “realistically, they apply much less when they wear makeup with sunscreen,” she says. Applying sunscreen first creates a strong base for sun protection, while makeup with SPF can serve as an additional layer—not your primary one.

What could be happening if your makeup is pilling over your sunscreen?

If your makeup starts balling up or peeling over sunscreen, product compatibility may be the culprit. As Dr. Yoo explains, “pilling occurs when two products have incompatible film-forming systems that don't bind to each other,” so as you blend, friction causes the formulas to roll up into little flakes. Common causes include an oil-versus-water mismatch (like a silicone-heavy primer layered over a water-based sunscreen), clashing polymers between sunscreen and foundation formulas, or simply not waiting long enough for sunscreen to fully dry before applying makeup. To avoid it, look for lightweight, makeup-friendly sunscreens with a dry or matte finish and similar base chemistry to your makeup—“silicone-to-silicone or water-to-water,” says Dr. Yoo.

Which sunscreen ingredients can make makeup slide off?

Rather than a single sunscreen ingredient causing makeup to slide off, it often comes down to the formula's texture and vehicle. Dr. Yoo notes that “fluid, essence, serum, and gel sunscreens work best under makeup” because they’re lightweight, absorb quickly, and leave minimal residue behind. Especially if you have oily skin, cream or balm formulas can be more problematic since they’re “often too emollient-rich to exist under makeup,” creating extra slip that can make foundation move around throughout the day, she says.

Do mineral and chemical sunscreens wear differently under makeup?

Mineral and chemical sunscreens can behave differently under makeup, but Dr. Yoo says the supporting ingredients and formula texture often matter more than the filters themselves. Chemical filters are dissolved into the formula, so they “integrate invisibly and tend to feel lighter,” though some require oilier carrier systems that may not play as nicely under foundation. Mineral filters, on the other hand, are suspended particles that can sometimes leave a cast or alter foundation shades, though nano or micronized versions tend to sit more smoothly.

Ultimately, Dr. Yoo says makeup compatibility comes down to factors like:

• Finish: “Matte formulas typically play more nicely under makeup than dewy or satin finishes.”
• Oil content: “Heavier, oil-rich vehicles can create extra slip and make the foundation move around.”
• Ingredient compatibility: “Film-forming polymers in sunscreen and foundation need to work together—not compete.”
• Absorption: “Waiting three to five minutes before applying makeup can make a bigger difference than you’d think.”

How we test and review products

When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing each and every product that’s included in each and every review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.

For our list of the best sunscreens under makeup, we considered each product’s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Every product was determined to have excelled in each category by our editorial team, which is composed of in-house writers and editors as well as contributors—along with special consideration from dermatologists. To learn more information on our reporting and testing processes, read our complete reviews process and methodology page.

Our staff and testers

A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.

After all, can we really say a skin-care product is the "best" for people over 50 if the only testers we’ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We’re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
