皮肤

皮肤 (pí fū) refers to the outer layer of the body that covers and protects the internal organs. It is the largest organ of the human body and plays a vital role in sensing temperature, pressure, and pain.

The character 皮 (pí) originally meant 'skin' or 'hide,' often used in the context of animal skins. 肤 (fū) specifically means 'skin' in a more human or bodily sense. Together, they form a precise term for the skin on the human body.

皮肤 is commonly used in medical, beauty, and everyday contexts. For example, people talk about skin health, skin care, or skin conditions. In traditional Chinese medicine, skin health is closely linked to internal well-being.
