Here's why:
* Sebaceous glands are tiny glands found all over the skin, except for the palms of the hands and the soles of the feet. They produce an oily substance called sebum.
* Sebum is a mixture of lipids, waxes, and cellular debris. It helps to:
* Moisturize the skin and hair, preventing them from becoming dry and brittle.
* Create a barrier against water loss.
* Protect the skin from bacteria and other microorganisms.
While sweat glands also contribute to skin moisture, their primary function is thermoregulation (cooling the body). Sebaceous glands are specifically designed for lubrication.
