Yes, you have to wear SPF even if you’re spending your days indoors.

How to protect your skin—both indoors and outdoors.

THANKS TO THE NECESSITY of physical distancing and WFH guidelines, it’s safe to say that our summer plans have been, well, altered. But one thing that shouldn’t change—no matter what the calendar says—is having a plan to protect your skin. Spending the majority of your time indoors is not, and has never been, an excuse to avoid daily SPF use. That’s because “UV light still gets through windows,” says Dr. Julia Carroll, a Toronto-based dermatologist and co-founder of Compass Dermatology. “UVA and UVB [rays] are more damaging, based on what we know right now. But we’re talking about blue light.”

Blue light, a high-energy visible light that’s naturally present and can also be emitted from devices, has previously been discussed in relation to eye health and its effects on sleep. But now, illuminated (pun intended) by 2020’s off-the-charts screen time, “digital aging” from blue light is the buzziest phrase in skincare. Brands like StriVectin and Ava Isa have launched products that combat blue light’s photo-aging effects using French rice germ or Micah, a preventive compound, while others, like Indeed, use supercharged antioxidants to fight damage.

“The majority of blue light that we’re exposed to comes from the sun, and a tiny portion of it comes from screens,” says Carroll, noting that although there is still limited research available on blue light’s impact on skin, a small but well-done study did show that it triggers hyperpigmentation and redness. “[This] highlights the fact that we should be paying attention to blue light as a potential source of skin damage. The more worrisome culprit, in terms of exposure, is the sun.”
