Combined Subcision with CO₂ Laser or PRP for Atrophic Post-acne Scars

The study aims to find the most effective treatment for atrophic scars left by acne. Atrophic scars are those that create indentations in the skin. The study compares three methods: subcision alone, subcision combined with platelet-rich plasma (PRP), and subcision combined with fractional CO₂ laser. The target group is individuals with atrophic post-acne scars, and the study takes place at Assiut University Hospital in Egypt. Understanding which treatment works best could significantly improve the appearance of acne scars, providing better options for those seeking cosmetic improvements. Participants will undergo a procedure called subcision, where a needle is used to release tight bands under the skin that cause the scar. This treatment is done on both sides of the face. In group I, PRP is injected on one side, while saline is injected on the other. In group II, a fractional CO₂ laser treats one side, with the other side receiving saline. Each patient receives three treatment sessions, spaced one month apart. Results are measured using scar grading systems and photography, ensuring a comprehensive evaluation. After treatments, participants are advised to avoid sun exposure and use sunscreen to protect their skin. Any discomfort is managed with cold compresses and pain relievers like paracetamol.
