HDD said:I was going to post about using it for sunscreen but thought maybe I should wait until I tried it again for sunscreen. So this us my first time using it for sunscreen. I sprayed arms, chest, face, and a little on my back before going to the beach for a few hours this past week. I also used some coconut oil but I don't recall how thorough or exactly where I rubbed the oil. I also took an aspirin. It was late afternoon mid 80's. I did not burn. My back was a little red but it was the least covered by SolBan along with my forehead (bangs). I am blond, I tan, but also burn. Everything turned to tan, no discomfort or peeling. So, next I will need to test in the morning and midday sun.
Haidut, would I need to reapply after a certain amount of time or after swimming? I usually don't stay in the sun too long anymore because I burn and don't like using zinc oxide. This will be great if it enables me to be out longer.
I think if you give it 30min-45min to absorb then it stays in the epidermal layer of the skin for up to a day. So, you should be OK with only one application per day. I guess the test would be if you feel a little rush after applying it. Most people do, and that's a sign that at least caffeine is already absorbed. But like I said above, studies show that 30min-45min is enough for the substances to get into the epidermis and not be easily washable.
I hope that helps.
