I got a bit sunburned and didn't realize until I hopped into the shower and noticed how the water kind of stung. I was then a bit red in several places and applied this. The next day, the redness was a lot tamer, and my skin wasn't as sensitive. By day two, it was as if I was never sunburned and just tan! Now I put this on after I shower if I had spent some time in the sun just in case to help my skin stay hydrated and soothed.
