The Full Story
Skin is the body’s largest organ by surface area, usually covering about 1.5 to 2 m² in adults. It protects against injury, infection, dehydration, and UV radiation. The skin also helps regulate temperature through sweat and blood flow changes. Its outer layer, the epidermis, constantly renews itself, while deeper layers contain blood vessels, nerves, glands, and immune cells. Because it is so large and exposed, skin health affects many other systems.
