Definition
角质 is a biological term referring to the tough, fibrous protein keratin that makes up hair, nails, horns, and the outer layer of skin. In everyday contexts, you'll hear it in skincare and beauty products (去角质 'exfoliate', 角质层 'stratum corneum'). It's a technical term, not used in casual conversation about skin texture.
