Core Tip
Core Tip: The treatment of hypertrophic scars on the nose is challenging due to high skin tension and rich sebaceous glands in this area. Conventional laser or intralesional injections often yield unsatisfactory results for recalcitrant focal lesions. We report a case of nasal hypertrophic scar successfully flattened using a 0.5 mm micro‑punch matrix drilling technique, with no recurrence or adverse effects. The micro‑punch approach may serve as a simple, safe, and promising alternative for this patient and warrants further investigation in similar cases.
