Acne is a disease that affects the skin's
oil glands. The small holes in your skin
(pores) connect to oil glands under the
skin. These glands make an oily substance
called sebum. The pores connect to the
glands by a canal called a follicle. Inside
the follicles, oil carries dead skin cells
to the surface of the skin. A thin hair also
grows through the follicle and out to the
skin. When the follicle of a skin gland clogs
up, a pimple grows.
Most pimples are found on the face, neck,
back, chest, and shoulders. Acne is not
a serious health threat, but it can cause
scars.Read more...
