I was ecstatic to find such a completely nontoxic sunscreen - and with no nanoparticles! Even Debra of Debras List noted that this products looks good! It is the best green sunscreen I have ever heard of and the company is nice to deal with also! They responded to my questions, disclose all ingredients and particle size, and offer a product that wont even harm fish in aquariums or the ocean. The price is reasonable too. Wow! - Lisa K.
