My dermatologist prescribed tretinoid 0,1´% + vitamin B , and vitamin C in AM. I noticed that after a month of using it, my skin is darker, my spots more pronounce and I have been burned on the side of my cheeks, on the line of my mouth. I have stopped since the treatment burned my skin, I have called my doctor Dermatologist but she is not returning my calls!. What can I do to get rid of the burn side effects? Do they go away? I heard of picosure lasser but I am afraid of the side effects.
