Your skin is your
largest organ, and it does a lot more than simply prevent you from spilling out
all over the place. Skin cells are constantly replacing themselves, making a
journey from the inner edge of your epidermis (your skin's outermost layer) to
the outside of your skin. As a skin cell ages and approaches the skin's
surface, the dying cell flattens out. Once on the surface, it joins countless
other dead skin cells and forms a protective layer that helps protect you from
bacteria and viruses.
Inside your hair
follicles, there are small glands producing oil called sebum. This oil mixes
with skin cells in the follicle and joins them on the journey outward. But when
there's too much sebum, too many dead skin cells or something on the surface
that blocks their exit from the follicle, a blockage can occur. Bacteria joins
the party, and the result is acne vulgaris, the most common form of acne.
While acne usually
affects teenagers and 20somethings the most, anyone of any age can get acne,
even babies. Our instinctual response -- picking at it, rubbing it and
canceling our social engagements -- doesn't help in the least, but fortunately,
there are some treatments available that can.
