Comparative Real-world Study on Ablative Fractional CO₂ Laser vs PRP With Microneedling for Acne Scar Treatment.

Participants will receive ablative fractional CO₂ laser therapy on one side of the face using the SmartXide DOT Fractionated CO₂ Laser system. Treatment parameters: 15 W power, 800 µm spacing, 600 µs dwell time, stack level 2. Sessions: 3, each one month apart.

Participants will receive intradermal autologous PRP injections prepared by double-spin centrifugation from 8 mL of venous blood, followed by microneedling with a Dermapen (12-needle cartridge, 1.5 mm depth). Endpoint: pinpoint bleeding. Sessions: 3, each one month apart.
