The Case For Wearing Sunscreen Indoors
It's 2020 and it's actually a thing to review conventional beliefs that are held to be true.
And only wearing sunscreen outdoors is one of them.
According to the American Cancer Society (ACS), the glass used in your car, home, and office windows block most UVB rays, but not all UVA rays. UVA rays go deeper into the skin and are the principal reason why you age faster with more sun exposure. So if you're sitting by a window or in a room with lots of sunlight, you'd be better off with some broad-spectrum protection.
The blue light coming from your electronic devices is also something to protect yourself from. While the jury is still out on an unanimous decision, a study published in 2014 in the Free Radical Biology and Medicine Journal showed that blue light can exacerbate hyper-pigmentation issues.
If you're using mineral sunscreens because of oily skin, chances are wearing sunscreen too often can clog your pores and break you out. So it may be worth finding a sunscreen that's advertised as non-comedogenic. It may also be helpful for you to find a double-cleansing routine as to prevent any residual sunscreen from clogging your pores.
