If our overstocked beauty cabinets tell us anything, it’s that skin care is ever-evolving. While gadgets and serums come and go, dermatologists remain firm on one thing: sunscreen is a must.

It’s not always easy to buy into the daily application, especially when benefits aren’t seen right away. And with extra time spent inside as we practice social distancing, questions may arise about when and where we even need to use it.

Below, we’re breaking down everything you need to know about wearing sunscreen, even if you aren’t leaving the house.

Why do we need to wear sunscreen at all?
Sunscreen protects the skin from damaging ultraviolet rays emitted from the sun. If left unshielded, these rays can contribute to premature aging (i.e. wrinkles, sun spots, leathery skin) and skin cancer. The two ray types, ultraviolet A (UVA) and ultraviolet B (UVB), each affect the skin differently. UVB rays are the most obvious, causing sunburns and a heightened risk of melanoma, while UVA exposure can lead to early aging as well as the development of cancer. Bottom line? Both require daily sunscreen application and it’s never too late to start.

Do we need to wear it indoors?
Yes. Windows may block out UVB light, but UVA rays can still shine into your home. Application is especially important if you sit near a window, but you should apply every day regardless so you’ll be prepared for that lunchtime walk or a quick drive to the store.

Additionally, recent studies even suggest that daily screen time may contribute to skin damage — an unwanted side effect of those daily Zoom meetings and Netflix marathons. “Your electronic devices and light bulbs emit high energy visible (HEV) light,” shares Dr. Joshua Zeichner, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. “Fortunately [these] do not cause skin cancer but are associated with premature aging and dark spots. Mineral sunscreens offer some level of protection against HEV light.”

When and where do we need to apply?
You should apply sunscreen anywhere and everywhere that your skin is exposed — face, neck, arms, legs. As for how often, it’s best to follow the same rule as the beach: apply every two hours. Multiple coats will give you a thicker defense and hit those spots you may have missed before, even if you don’t break a sweat. That said, if you aren’t near sunlight at all, one even layer in the morning will be enough.

What products should we look out for?
“I usually recommend mineral blocker sunscreens when indoors,” Dr. Zeichner says. “They provide broad-spectrum UV protection against UVB and UVA rays that penetrate through windows. Plus, ingredients like zinc oxide can help protect the skin from HEV light damage.” His favorites are Aveeno Positively Mineral Sunscreen SPF 50 and Solara Suncare Time Traveler Ageless Daily Face Sunscreen.

Generally speaking, it’s a good idea to look out for that “broad-spectrum” label, and SPF 30 or higher is recommended. If you use SPF makeup for coverage, you might also try pairing it with a stand-alone sunscreen. There’s a good chance normal makeup application won’t fully protect the skin without some extra help.
