Q. Why should I wear sunscreen if I’m only going outside for a little while?
A. It is important to wear sunscreen any time you will be outside to guard against UVR exposure that can cause skin cancer. Typically, skin cancer can be divided into two categories: nonmelanoma and melanoma. The most common type of nonmelanoma skin cancer is Basal Cell Carcinoma (BCC), followed by Squamous Cell Carcinoma (SCC). You may think you don’t need protection if you are just running in and out of your office a few times a day, but even low dose repetitive exposure can cause skin cancer.
According to the American Academy of Dermatology, there are three things that your sunscreen should do:
Sunscreen should protect against both UVA and UVB rays
Sunscreen should have a sun protection factor (SPF) of at least 30
Sunscreen should be labeled “water-resistant”
Regular daily use of sunscreen reduces the risk of developing SCC by about 40% and the risk of developing melanoma by 50%.
