What this trial studies

This is a single-arm interventional study using a micro-coring device (MCD) to treat various non-keloid scars in up to 30 adult participants at a single site. Participants will receive the device treatment and be followed for safety and effectiveness outcomes for 6 months after their last treatment. Outcomes include the Patient and Observer Scar Assessment Scale (POSAS), the Acne Scar Severity Scale (ASAS), and a Subject Satisfaction Scale. Key exclusions include keloid-prone patients, recent scar treatments, active infection, significant immune compromise, pregnancy, and use of anticoagulant medications.

Who should consider this trial

Good fit: Adults aged 18 or older with non-keloid scars (including acne, surgical, or stretch scars), Fitzpatrick skin types I–VI, who can give informed consent and have not had scar treatment in the past 6 months are ideal candidates.

Not a fit: Patients with a history of keloid formation, recent scar treatments, active infection, significant immune compromise, pregnancy or breastfeeding, active heavy smoking, or on anticoagulant medications are unlikely to be eligible or benefit.

Why it matters

Potential benefit: If successful, the device could meaningfully reduce scar appearance and increase patient satisfaction with a minimally invasive approach.

How similar studies have performed: Early and small clinical reports of micro-coring devices have shown promising results for scar appearance and skin tightening, but larger controlled trials are still limited.
