Worked for my perioral dermatitis
I got this because I was struggling with perioral dermatitis. I don’t know if it was because of this but my skin has cleared up over the last few weeks (been having issues for a few months). I’m going to keep using it because of that even after my face has cleared up.

Nothing
The only issue I have is that it leaves a lot of residue in the shower or tub. Not on the skin
