For each participant, a questionnaire will be filled out with the following information: gender, age, skin type, profession, current or previous history of smoking, use of medications, and presence of active acne. To assess the degree of scarring of the participants, the scale "Quantitative Global Scarring Grading System for Postacne Scarring" will be applied. After this evaluation, patients will be randomly allocated in each study groups (simple randomization). The randomization system was performed with the Microsoft Excel randomization program. Patients in both groups will undergo three sessions of laser treatment or three treatment sessions with microneedling, with an interval of six weeks between them.
