By now, l think we all know that spending too much time in the sun can increase risk for both skin cancer (the most common of all cancers) and premature skin aging.

If you're spending time in direct sunlight, apply your sunblock about 15-30 minutes before sun exposure to allow for full absorption, and re-apply every two hours. Because the sunlight will cause the active ingredients in your sun protection to break down, reapplying is essential.

The Skin Cancer Foundation recommends  reapplying your sunscreen after any sort of excessive sweating, swimming, or even toweling off. Basically, if the sunblock can be wiped away, it needs to be reapplied. 

For someone who loves to wear makeup, the idea of reapplying sunblock to my face every few hours can feel a little ridiculous, which is I love the Kate Somervile's Uncomplicated SPF 50 Makeup Setting Spray. It's perfect for reapplying over your makeup. My current favorite SPF go-to is Suntegrity's Natural Mineral Sunscreen for Body because it’s effective, cruelty-free and chemical-free. An awesome clean, physical sunblock with added antioxidants is Umbra by Drunk Elephant (best for drier skin types) and Eltamd’s UV Clear (super lightweight!)
