PRP with fractional CO₂ laser to improve acne scars

Evaluating the Effectiveness of Platelet-Rich Plasma as an Adjunct to Fractional Carbon Dioxide Laser Therapy in Improving Facial Acne Scar Appearance: A Randomized Controlled Trial

Not applicable Interventional Gujranwala medical college District Headquarters Hospital, Gujranwala · NCT07352215

This will test whether adding your own platelet-rich plasma (PRP) to fractional CO₂ laser treatment can improve moderate-to-severe acne scars in adults aged 18–40.

What this trial studies

This is a single-blinded randomized controlled trial enrolling 70 adults with moderate-to-severe facial atrophic acne scars to compare fractional CO₂ laser plus topical PRP versus fractional CO₂ laser alone. Participants are randomly assigned to two groups and will receive three treatment sessions spaced four weeks apart, with PRP prepared using a standardized double-spin centrifugation method. The primary outcome is change in scar severity on the Goodman and Baron Quantitative Acne Scar Scale; secondary outcomes include redness, swelling, pain scores, and patient satisfaction. Patients are blinded using a placebo-filled syringe in the control arm and data will be analyzed using appropriate statistical tests.

Who should consider this trial

Good fit: Adults aged 18–40 with moderate-to-severe facial atrophic (post-acne) scars, Fitzpatrick skin types I–V, who can attend three treatment sessions and follow-up and do not have active infections, pregnancy, uncontrolled diabetes, or a history of keloids.

Not a fit: People with active acne or skin inflammation, a history of keloid or hypertrophic scarring, photosensitive disorders, melasma, bleeding disorders or anticoagulant use, recent resurfacing procedures, pregnancy/breastfeeding, or those unable to comply with follow-up are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, adding PRP could produce greater scar reduction, speed healing, and reduce post-laser redness and downtime.

How similar studies have performed: Prior small trials and pooled analyses have reported improved scar outcomes and faster recovery with PRP combined with laser versus laser alone, but high-quality large randomized evidence is limited and results have been variable.
