This type of scarring will not be "gone" in a single fractional co2 / erbium treatment. you need fillers, subcision and lasers treatment in combination in a series of treatments to get better outcomes and then long term you will need maintenance. Best, Dr. Emer.
Acne scar treatment commonly requires a combination of modalities including lasers, fillers, chemical peels, and micro-needling. An in-person consultation is best.
