Acne scarring
One of the most common reasons people choose microneedling, and one of the areas it helps most. Rolling and boxcar scars often soften as new collagen forms beneath them; deep "ice pick" scars respond more slowly. Honestly: microneedling improves scarring, it does not erase it. Most people see scars become softer and less visible over a series, and the improvement keeps building for months.
