I am a fan of thinksport's sunscreen! I purchase it at a local shop in town as it's not available at grocery stores. It's dermatologist recommended with the active ingredient of Zinc Oxide 20%. It's a safe sunscreen that I use on my son and I without all the chemicals. My son was breaking out to any sunscreen I purchased from L'oreal to Coppertone not to mention I wasn't comfortable with all the chemicals in the lotion. The only downside I find it the price but it does last a long while.
