In addition to being safer, applying sunscreen to your entire face is simply easier, according to Sturm. That way you don't have to worry about missing spots. Masks are prone to shifting, after all. So you even want to protect your lips. Kissers have very thin skin that can be damaged by the sun and are very susceptible to mask friction. EOS The Guardian 100% Natural SPF 30 Lip Balm, $3.49, offers protection from UVA and UVB rays to cover all your bases.

There are more masks and designs by the day. They vary in terms of protection against the virus and the sun. But masks don't guarantee sun protection.
"As a general rule, the darker and more tightly woven the fabric is, the more protection it affords," says Dr. Elizabeth Hale, board-certified dermatologist and clinical associate professor of dermatology at New York University Langone Medical Center. "However, masks that are light in color and material (both surgical and cloth) let through some ultraviolet rays with no real regulation so it's a good idea to protect your entire face every day."
That doesn't mean you can skip sunscreen when wearing a dark mask. A black mask does offer slightly more sun protection, as does a denser weave, but it's still not enough.
On the flip side, Nussbaum recommends masks in lighter colors because they will not attract the sun. She also prefers paper masks for acne-prone patients. "It is really trial and error because there are so many options..."

Excellent sunscreen habits dictate that we reapply sunscreen (boasting SPF 30 or higher) throughout the day. The same applies when wearing a mask. Linkner suggests reapplying SPF every two hours when outdoors in sustained sunlight, including under your mask. If you're inside most of the day, it's less important to continuously reapply SPF. The most important thing is to get a good first coat in the morning. Hale suggests mineral SPF powders or sprays for easy application.

Any devoted lipstick wearer knows that keeping a lip product on under a mask presents some challenges. The same can be said about sunscreen. Invariably some sunscreen will get absorbed or wiped off on a mask, which is why it's important to reapply sunscreen every few hours. Hale recommends making sure sunscreen is completely dry before putting on a mask.
