How much time between acne scar treatment is possible before end result is affected?

Isotretinoin intake while on acne scar treatment is considered generally safe based on the latest research studies published from 2014 onwards. Because acne scarring is associated with substantially reduced quality of life, early initiation of effective treatment is desirable. Ablative CO2 fractional laser treatment for acne scarring seems to be safe regardless of isotretinoin use (10-60 mg/d) [1]. Follow-up was for at least 6 months post-treatment to evaluate side effects. No major and permanent side-effects were seen.

Hi, The most important age factor to consider when to undergo acne scar treatment is not the age per say but when the acne is no longer active. This is because continued active acne will result in new scars and undo the benefits of the acne scar treatment. For some patients, active acne may persist way into their 20’s and even 30’s. In my experience, the clinical response to acne scar treatment is quite similar when treatment is done in the 20’s or in the 30-40’s. Hope this helps!
