What cools the skin?

Explanation:
Cooling the skin mainly happens through evaporation of sweat. Sweat is produced by sweat glands in the skin, and when it evaporates from the surface, it absorbs heat from the body, lowering skin temperature and helping regulate body temperature. This is why you feel cooler after sweating and why sweating kicks in during heat or exercise. Melanin is the pigment that helps protect skin from UV light, not cooling. Sebum is an oily substance that keeps skin moisturized, not cooling. Keratin is a structural protein in the skin that provides protection and strength, not cooling.
