Comparative study of the efficacy of Platelet‐rich plasma combined with carboxytherapy vs its use with fractional carbon dioxide laser in atrophic acne scars

Acne scars are a major concerning problem to all acne patients affecting their quality of life. Platelet‐rich plasma (PRP) and fractional CO2 laser are innovative treatment modalities for acne scars. Carboxytherapy can also be used to improve scar tissue through the increase in collagen deposition and reorganization, and the improvement in skin texture and tone.
