Sweat vs. Sebum: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Sweat is a clear, salty liquid produced by sweat glands for cooling the body, while sebum is an oily substance secreted by sebaceous glands to lubricate and protect skin and hair.
Key Differences
Sweat, primarily water with traces of minerals, urea, and lactate, is produced to regulate body temperature. Sebum, an oily secretion, is composed of triglycerides, wax esters, and squalene, serving to moisturize and protect the skin and hair.

Sweat is a clear, watery fluid that evaporates from the skin surface, causing a cooling effect. Sebum is a viscous, oily substance that coats the skin and hair, providing a barrier against environmental damage.

The production of sweat increases during physical activity or in hot conditions to cool the body, while sebum production is more constant, maintaining the skin's and hair’s natural moisture and flexibility.
