Marie528 replied to Nikki09's topic in Hypertrophic (raised) scarsFinally I see someone with similar hypertrophic to mine. Mine wasn't caused by tretinoin or clindamycin (although I do use both now.) The ones on my chin just sort of popped up overnight and the rest came up after pimples healed, etc. Since you didn't get a lot of feedback here I'd recommend posting your pics on the subreddit r/skincare addiction. I'd be very interested to hear what they think it is since I haven't been able to find any answers myself either.
