Needling, lasers, and Meso-Botox for hypertrophic and keloidal scars: A comprehensive review study on promising procedural treatments

Scars are among the most prevalent referral cases of dermatology clinics, including atrophic, hypertrophic, or keloidal scars. Approach to scar usually needs a holistic trend, attention to individualized characteristics, and combination therapy. Scars usually need multiple sessions of therapy and the use of combination therapeutic approaches to reach the most acceptable outcomes by safe modalities. Studies on scars are always one of the most important fields of research in medicine, especially in dermatology. For writing this review study, we searched all the databases to find the most relevant and the newest studies related to our topic, because based on expert opinion, this topic may be really practical and interesting for dermatologists and all physicians of various specialties or subspecialties who manage and treat various kinds of scars, including hypertrophic scars and keloids. Based on our results, we concluded that different procedures, which basically use needling, lasers, especially pulsed dye laser (PDL) and carbon dioxide (CO(2)) laser, and MesoBotox (micro-injection of botulinum toxin), are really promising therapeutic options for hypertrophic and keloidal scars and a combination of these therapies results in more efficacy and lesser side effects in the field of scar management.
