Facial scar remodeling with fractional CO2 laser plus PDRN versus CO2 laser alone
Official title: Comparative Study for Facial Scar Remodeling Using Fractional Carbon Dioxide Laser Combined With Polydeoxyribonucleotide (PDRN) Versus Fractional CO₂ Laser: A Randomized Controlled Clinical Study
Run by Misr University for Science and Technology · NCT07472192 · Data updated 2026-11-12
This test checks whether adding PDRN injections to fractional CO2 laser treatment helps adults (18–50) with recent facial surgical or cut scars (1–6 months old) heal faster and look better than laser alone.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–50 with recent (1–6 month) facial surgical or cut scars who can attend in-person visits and provide informed consent.
✕Probably not a fit
People who are pregnant or breastfeeding, allergic to PDRN, taking medications that affect wound healing, or with uncontrolled medical conditions are unlikely to benefit or be eligible.

What this trial studies
This Phase 2 interventional study compares two approaches for remodeling maxillofacial scars: fractional CO2 laser alone versus fractional CO2 laser combined with polydeoxyribonucleotide (PDRN). Eligible adults receive one of the two treatment approaches and are followed for clinical signs of scar improvement, healing speed, and safety outcomes. The study excludes pregnant or breastfeeding people, anyone allergic to PDRN, and those on medications or with conditions that impair wound healing. Outcomes are measured by clinical assessments and safety monitoring during scheduled in-person visits at the study site.
Why it matters
Potential benefit: If successful, combining PDRN with fractional CO2 laser could speed healing and improve the appearance of recent facial scars compared with laser alone.
How similar studies have gone: Fractional CO2 laser is an established scar treatment and small studies suggest PDRN may aid wound healing, but evidence for the combined approach is still limited.
