As you know, sunscreens vary in SPF. In Australia our sunscreen standards have the following below levels. No sunscreen can block all UVB rays. However, in terms of percentages, a sunscreen with these differences might seem small but over a lifetime, it all adds up and every little bit of protection helps.
Always read the label. Follow the directions of use. Sunscreens are only one part of sun protection. Avoid prolonged high-risk sun exposure. We recommend that you reapply sunscreen every two hours or more often if necessary regardless of its SPF.

After months of quarantine, you have likely become acclimated to the new norm of working from home, social distancing and limited time spent in public spaces. Perhaps you have transformed your backyard into a summer camp for adults complete with evenings spent around a fire pit drinking wine from your decanter. At the same time, your favorite movie plays on your outdoor projector screen with the high-quality sound emitting from your portable Bluetooth speakers.
While you likely know how imperative it is to wear sunscreen outdoors and reapply your SPF after you emerge from the water or work up a sweat. However, now that people who can work from home spend most of their days indoors, does that mean you need to wear sunscreen inside? And what is the best sunscreen for your face while working indoors? To discover the answer to these questions and more, we consulted medical experts to find out how to shop for your next sunscreen, whether you choose to wear SPF indoors or not.
According to four of the five dermatologists we interviewed, you should wear sunscreen indoors. If you're sitting near windows — or in front of a computer screen — you're exposing yourself to potentially skin-damaging light.
Ultraviolet A rays, which can cause signs of aging like loss of elasticity and wrinkles, "can penetrate windows and cloud cover," according to the nonprofit Skin Cancer Foundation.
Unfortunately, not all windows are treated with protection from the sun's harsh rays. Unless you're in a windowless room, you may want to consider slathering on SPF. It does not cause tanning, so you may be unaware of how much UVA exposure you are getting," says Gmyrek. Those cells that remain increasingly get damaged over time through exposure, resulting in skin cancer," she says. If you ask me, the solution to this problem is simple: Get out of the sun.

According to Markowitz, the blue light emitted from digital screens — including your computer, phone, tablet and TV — can affect your skin in two ways:. If you choose to wear sunscreen indoors, your next step is to decide what formulation meets your skin and SPF needs. Physical blockers use iron oxide, zinc oxide or titanium dioxide as their active ingredients, says Gymrek.
Blue light filters on your screens are also very helpful as are blue light blocking glasses. In the short term, your skin responds to sun exposure by becoming inflamed. As a result of a sunburn, your skin adapts by tanning. The more prolonged your exposure, the more severe a burn may be.
Tanned skin is also the result of melanin released in the affected area. The negative effects may not always be seen by the naked eye. Wearing a broad-spectrum sunscreen with the right SPF can help minimize this type of damage.
In fact, according to the Skin Cancer Foundation , wearing SPF 15 sunscreen may reduce your risk of melanoma skin cancers by up to 50 percent, as well as non-melanomas by 40 percent. UVB rays consist of shorter wavelengths that can cause burns, wrinkles, and age spots. UVA rays are longer and can lead to burns and skin cancers. Wearing sunscreen not only protects against direct UV exposure incurred during outdoor activities, but it also protect your skin from day-to-day exposure.
This includes driving, walking to your place of work or a class, and taking your kids to the park. Left unprotected, even seemingly small amounts of sun exposure can add up over time. At minimum, you should wear a sunscreen-containing moisturizer on your face, neck, and chest every single day. Each sunscreen contains an SPF, or sun protection factor.
The ideal SPF in a sunscreen depends on your exposure level to the sun. They refer to the time it would take for your skin to burn without wearing sunscreen, rather than offering a specific level of protection. So, for example, an SPF of 30 means your skin could take 30 times longer to burn than it would if it were left unprotected. This is only true though if you apply it correctly in the right amount. This is also how you can still get tan while wearing sunscreen.
There are some cases where a higher SPF may be needed, though, such as if you have a history of skin cancer, albinism, or immune disorders that make you burn easily. You can also talk to your dermatologist about the exact SPF you should be using. They may even recommend adjusting SPF for certain times of the year, as well as your location.
