All effective acne scar treatments work by causing controlled injury to the dermis and stimulating new collagen formation over the next 2-6 months. Once the new collagen is formed, benefits are long-lasting.

Most doctors will recommend a duration of 4-8 weeks between each treatment. Treatment duration less than 4 weeks may be overly aggressive leading to potential unwanted side-effects of prolonged redness or pigmentation. Treatment duration beyond 3-6 months lead to a rather protracted overall treatment course but may not affect end result significantly.

Hence, it may be best to keep the duration between treatments between 4-12 weeks for best and consistent treatment outcomes.
