The American Academy of Dermatology (AAD) states that, as long as your sunscreen includes an SPF value of 30 (or higher) and broad-spectrum UV protection, it can be considered an effective sun protection option.2 SPF 50 reflects/absorbs approximately 98% of UV rays, while SPF 30 reflects/absorbs approximately 97% of the sun’s rays, according to the Skin Cancer Foundation.1 If you’ll be swimming or sweating, the AAD also recommends using a water-resistant sunscreen with at least SPF 30.2 For any specific questions about choosing between SPF 50 vs. 30, consult with a board-certified dermatologist for personalized advice.
