かさぶた

かさぶた is the dry, hard crust that forms over a wound as it heals. Almost always written in hiragana. The kanji 瘡蓋(かさぶた) exists but is rarely used.

Common collocations

• かさぶたができる (a scab forms)
• かさぶたが取(と)れる (the scab comes off naturally)
• かさぶたを剥(は)がす (to peel off a scab)

Usage

Children are often told not to pick at their scabs: かさぶたを剥(は)がさないで (don't peel your scab off). Peeling a scab prematurely can cause scarring.
