dear sir , acne
in male is a part of genetic effect upon sebaceous glands of the body and as you are telling, your son also gets it. Have a zero oil diet, use salicylic acid
face wash and do not pick your nodes. they give you scars
. and the scars which are on ace would need plastic surgery
in form of excision or fillers or dermabrasions depending upon their status. hope you move in right direction now.
