🎨 剥 = peel/strip + げる: the paint or colour peels off a surface and wears away
剥 means peel or strip, so 剥げる is what happens when paint, gilding or colour peels off or wears away. Its transitive partner is 剥がす, 'to peel something off'. The same verb also describes hair coming off, as in 剥げ頭 for a bald head.
剥 — 录 (carve) + 刂 (knife radical)
剥 is a semantic compound: 刂 (knife) on the right shows the action, while 录 on the left originally depicted carving or scraping. Together they convey peeling or stripping something off with a blade. The two readings split usage: bāo in everyday speech (peel fruit), bō in compounds (剥削 exploit).
