These glands are 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 which:
* Moisturizes the skin: Sebum helps to prevent the skin from drying out.
* Softens the skin: Sebum makes the skin feel smooth and supple.
* Protects the skin: Sebum forms a barrier that helps to protect the skin from bacteria and other harmful substances.
It's important to note that the amount of sebum produced varies from person to person and can be influenced by factors like age, hormones, and genetics.
