Works when working outside and heavy activities
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Doesn't go on greasy. Doesn't stink. Don't get sunburnt wearing it.
