I got Fraxel treatment done three weeks ago for cafe au lait spots. They were healing normally, until yesterday. I woke up with a bad rash on the treated areas. The skin is swollen, red, bumpy, and very itchy. It is almost unbearable, I want to scratch the skin so badly. Is it a normal side effect? I mean, I understand that the skin is red, sensitive and swollen right after the treatment, but three weeks later? Is this serious? Are there any ointments? Will it go away? Please help!
