When it comes to protecting the skin, sunscreen, otherwise known as sunblock, can effectively reduce the risk of skin cancer due to the sun’s UVA and UVB rays. But many patients who visit Rendon Center Dermatology and Aesthetic Medicine are confused as to the rules regarding the application of sunscreen. How often do I have to apply if I’m outside all day? What if I’m staying indoors? Patients can get the correct answers to these questions when they ask the right professionals!

Why do I need to wear sunscreen each day?

Everyone must apply sunscreen to exposed skin every day. You may not realize how often your skin is exposed to the sun during a day not spent outdoors. Walking from the closest parking lot into your office can leave skin exposed, as well as spending time with the kids on the front porch in the evening hours. Even driving your vehicle to and from work and activities can expose the skin to unwanted sun damage.

How often do I reapply sunscreen when spending time indoors?

If you are working in an office that is not near a window, you may just need to reapply sunscreen once during the day to cover your skin when walking to and from the office or commuting from work and home. However, if your desk is in an office with a nearby window, you can still get sun exposure. Reapply more often during the day if your workspace has sun exposure. This is because the sun’s ultraviolet rays can still penetrate through glass, so driving your car with the windows up or working near a window in the office can still cause cumulative sun damage to the skin and increase your risk of cancer.
