I used this sunscreen as directed while being outside all day and it was as if I had used no sunscreen at all. I ended up with second and third degree burns on my legs and had to be hospitalized and have two surgeries. I have no idea if the product was defective or caused some sort of reaction for me… I chose it because I do have many ingredient sensitivities but this product looked safe for me. I was out with friends who were all using different sunscreens, we all reapplied together, yet I was the only one badly burned.
