When I first started treatment, I had deep and red acne scars all over my face. I didn't expect my skin to become smooth after just one or two procedures. While monitoring my skin condition, I alternated between scar treatment and skin regeneration management, and on days with severe irritation, I waited until my skin fully recovered before undergoing the next treatment. At the one-month mark, I honestly couldn't see a significant difference. After about three months, the redness began to decrease, and by six months, I started to notice that the boundaries of the depressed areas became more gradual than before. Not all of the deep scars have completely disappeared yet. Although it was a long treatment process, I feel rewarded for my consistent visits as I confirm that my skin is gradually improving.
