Over 6 months ago I took a antibiotic that caused my mouth to tingle and swell, the corners of my mouth became inflamed and cracked.... It healed and went away but left behind two dark spots on the sides of my mouth... (I'm Latin I have tanned skin) I tried hydrq. 4% it didn't help.... Now I'm trying Ammonium lactate and I still see zero improvement. I don't want a cream that will work in a year, I want the spots gone now... What peels or lasers would be effective ?
