创痕 (chuāng hén) literally combines 创 (chuāng), meaning 'wound' or 'injury', and 痕 (hén), meaning 'mark' or 'trace'. Together, it refers to a visible physical scar left after a wound has healed — not just any mark, but specifically one resulting from injury, surgery, or trauma. It emphasizes the lasting, often raised or discolored, evidence of past damage to the skin or tissue.

This term is more formal and literary than everyday words like 疤 (bā, 'scar') or 疤痕 (bāhén). It appears frequently in medical reports, literature describing physical or emotional trauma, and news articles about accidents or violence. While it can be used metaphorically for psychological scars (e.g., 'emotional 创痕'), its primary domain is physical health and bodily recovery. It carries a subtle connotation of seriousness and permanence — a reminder of harm endured and survived.
