I had a rash that was red and itchy at the corner of my mouth. I used some hydrocortizone and it went away, but didnt clear up... Then my doctor told me to use some eurcerine moisturizer... But its still not clearing up after a few month... Its just this purple/slightly dark spot where the red, itchy rash used to be. I dont feel anything, its smooth and everything, its just the color. Help...
