 [ Symptoms ] hi i have acne problem on my back it leaves black scars in the last 3 years acne problem is spreading to my shoulders hi i have acne problem on my back and it leaves black scars which has not come back to normal skin even after 3 years now the acne problem is spreading to my shoulders i am 34 years old and i have been on two courses of doxycycline tablets in the last one year still there seems to be no effect on the acne problem i have been prescribed adapalene and benzoic acid creams done chemical peeling too but there is no change in the problem your help and advice is appreciated [ Disease ] you are taking the proper medications and appear to be under the care of dermatologist at age 34 acne is uncommon but as you know can affect adults i do not know if you are male or female and of course i have no way of seeing your acne or black scars over the internet as much as i would like to offer you some profound insight it is very difficult to do so in this forum my only suggest is for you to keep working with a good dermatologist until this problem is controlledsolved i know it is frustrating but medical management is really your only option at this point
