Sebaceous glands are found all over the
skin, except the
palms and
feet, and are normally found adjacent to
hair follicles. They produce
Sebum, an antifungal oil made up of
fats,
cholesterol,
Wax esters,
protein and salts that help keep the skin
clean, hydrated and soft. Sebum also keeps your
hair supple.
When excess Sebum collects in the Sebaceous glands you get a pimple and once the Sebum is oxidized it changes color and turns into a black head. The larger Sebaceous glands are found on the face, chest and neck and they increase production of Sebum during adolescence and are one of the main causes of acne.
