Background: Despite improvements in acne treatment, post-acne scarring is still a widespread issue. Scarring is difficult to treat and difficult to avoid. Inflammatory mediators and enzymatic breakdown of collagen fibres and subcutaneous fat are likely involved in the aetiology of atrophic acne scarring. Objective: Review of the literature on options of treatment of post acne scar. Methods: PubMed, Google Scholar, and Science Direct were some of the places we explored for information about post-acne scarring and its treatment. Between January 2000 and May 2021, however, only the latest or most comprehensive study was considered. The authors also assessed the usefulness of references taken from similar books. We haven't paid attention to non-English documents because we don't have the time or money to translate them. Unpublished articles, oral presentations, conference abstracts, and doctoral dissertations were all widely acknowledged to not constitute valid scientific research. Conclusion: Facial resurfacing procedures like dermabrasion and microdermabrasion mechanically ablate damaged skin and stimulate re-epithelialization. When performed properly, dermabrasion can remove the epidermis and reach the reticular or papillary dermis underneath. Both invasive and noninvasive treatments have been tried with varied degrees of success to cure atrophic scars, but it is still difficult to reach the aim of complete improvement, even with the most expensive approaches. Consequently, there is a growing need for therapeutic approaches that are both highly successful and very inexpensive in the treatment of acne scars.
