My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.

great product - it must be blended in well
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Love this stuff. The roll-on makes it easy to apply on the go. It leaves a white streak unless you blend it in. I don't mind the white streak - at least I know I applied the product.
