Azelaic acid
acne
"I love this. Trick is- wash your face, dry it, let it dry for 10+ minutes without lotion (yes this is uncomfortable for a while) then the stinging is greatly minimized or there's none at all. Also, use pea size. I've had cystic acne all over my face and chest since 15 and I'm 33 now. I also had red acne scars all over my face. They're gone. I've been on this medicine for 6 months and my skin texture is smooth and beautiful, red scars are gone, new stress pimples/acne are gone. I know medications aren't right for everyone, but for me, this stuff is awesome."
