So you’re getting ready for another day of working from home. Face washed and moisturized, coffee in hand, window blinds open, and computer ready to go. But there’s one thing you're missing: sunscreen. While it’s easy to think that just because you're inside you don’t need sunscreen, that’s not the case. From the radiation coming through your windows to what's emitted from electronic devices, it’s important to wear a broad spectrum SPF everyday regardless if you’re staying indoors or going out. Here’s why:
Types of Damaging Radiation
There are different types of radiation that can affect your skin:
Ultraviolet A: UVA rays have a longer wavelength and are associated with skin aging and skin cancer. They account for up to 95% of the UV radiation reaching the earth and penetrate through windows and clouds.
Ultraviolet B rays: UVB rays have a shorter wavelength and are associated with burning your skin and skin cancer. UVB rays do not penetrate through glass.
Blue light: Blue light is a short wavelength that produces high amounts of energy. It is found on TVs, Smartphones, computers, laptops, tablets and gaming systems, electronic devices, LED and fluorescent lighting. Studies have found that blue light can cause skin aging like hyperpigmentation.
Infrared Radiation: In addition to the sun, IRA is also emitted from electronics like your computer and blow dryers. These rays penetrate your skin and can cause free radical damage in addition to skin dehydration and aging.
Indoor Radiation + How to Protect yourself
When it comes to indoor protection, the main takeaway is that UVB rays do not penetrate through windows but more than 50% of UVA rays do penetrate through glass; this is why broad spectrum protection is essential! Sunscreen that does not indicate broad spectrum protection only blocks the UVB rays while Broad Spectrum sunscreen protects you from both UVA and UVB rays. Studies show that UVA rays degrade collagen and cause other premature again along with putting you at risk for skin cancer.
While UVA ray exposure is the primary concern of indoor exposure, studies are finding that blue light and infrared radiation from your electronic devices may also put your skin at risk and prone to hyperpigmentation and dehydration. Although more research needs to be done on the extent of this damage, Andrew Birnie, MD, a dermatologist and skin-cancer specialist explained to the Guardian that the best thing people can do is apply broad spectrum SPF 30 sunscreen every day.
So during this time of prolonged indoor days don’t forget to add applying broad spectrum sunscreen to your morning routine and reapply throughout the day. Our sunscreen is made with hydrating ingredients like aloe, cucumber, and vitamin E so when you’re protecting your skin you’re also nourishing and hydrating it too.
