I am 35 years hold and suffer from occassional acne and rosacea. I used Diprogenta, as I had developed contact dermatitis when I tried using tooth paste to cure a recent eruption I had. The spot cured and the inflammation went down completely. However, it has left a dark reddish spot on the face. Please advise. Usually, when I get an eruption and it cures, I don;t really get a dark mark, as the one that has developed. Should I continue usign diprogenta or fucidin. Is there an alternative? Please advise.
