How effective is alpha-hydroxy acid products in removing acne scars?

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most important age factor to consider when to undergo acne scar treatment is not the age per say but when the acne is no longer active.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!

Hi, Acne marks (post-inflammatory erythema and hyperpigmentation) will gradually fade on their own over several weeks/months, so do not worry. It is important to prevent new acne from occurring (check out the Acne section for the various strategies to do so) as new acne will cause new marks to occur. Hope this helps.
