When you’re deciding which sunscreen to buy, do you ever wonder how high the SPF (sun protection factor) should be for the best protection? The SPF label means that a product blocks and absorbs UVB rays which are the main cause of sunburn and skin cancer.
Knowing that, you may be surprised to find out what a higher number means.
Baystate Health dermatopathologist Dr. Jean Henneberry explains the difference between different SPF levels, and offers advice for choosing the right sunscreen for you.
