I had acne scars? depressed scars and such on my face, so I decided to get dermatology treatment, and since there happened to be a discount event, I had 3 sessions.
I do think it has definitely improved, but it still feels like a long, long way to go. For skin, I guess you really do have to pour money into it
To really improve acne scars, 3 sessions are not enough, and I think I would need 5-7 more sessions, but it hurts so much
