I got a terrible sunburn at the beach with this. I had used it for shorter days out in the sun and it seemed fine, but I had never really tested it with prolonged exposure. Today, I wore this, and by chance my husband used a different product (also spf 30), and I am TERRIBLY burnt as if I put nothing on while he is fine. I did apply extremely generously, and I did reapply as well, plus put a shirt on after a while. (I haven't gotten a sunburn like this in 20 years at least, I am very careful!!!) Awful product. I just threw it away. I am lucky I had a different product on my face!!!!! I am shocked at the terrible quality.
