Acne
is a skin condition that shows up as different types of bumps They
include whiteheads, blackheads, pimples, and cysts What causes these
annoying bumps? Well, your derma is covered with tiny holes called hair
follicles, or pores Pores contain sebaceous (say: suh-bay-shus) glands
(also called oil glands) that make sebum (say: see-bum), an oil that
moistens your hair and skin.
Most of the time the glands make the right amount of sebum, and the
pores are fine But sometimes a pore gets clogged up with too much
sebum, dead skin cells, and germs called bacteria This can cause acne
vulgaris If a pore gets clogged up, closes, and bulges out from the
derma that's a whitehead If a pore clogs up but stays open, the top
surface can get dark and you're left with a blackhead Sometimes the
walls of the pore are broken, allowing sebum, bacteria, and dead
peeling cells to get under the skin This causes a small, red primary
infection called a pimple Clogged-up pores that open up deep in the
blemish can lead to bigger infections known as cysts.
When tissue suffers an injury, the body rushes its repair kit to the
injury site Among the elements of the repair kit are white blood cells
and an array of inflammatory molecules that have the task of repairing
tissue and fighting infection
White blood cells and disturbing molecules may remain at the site of an
active dermatitis lesion for days or even weeks In people who are
susceptible to scarring, the result may be an acne scar.
The occurrence and incidence of scarring is still not well
understood, however There is considerable variation in scarring between
one person and another, indicating that some people are more prone to
scarring than others Scarring frequently results from severe
inflammative nodulocystic acne that occurs deep.
Acne Care: What Works
Acne is caused when the hair follicles in our skin get blocked. No one knows precisely why these blockages occur, nor why they are more severe in some people than in others, even in different members of the same family. It also is not known why acne commonly first occurs after puberty, although the sebaceous glands grow considerably at this time, which could be a factor. The oil produced by hair follicles, called sebum, is normally beneficial because it helps prevent the skin from drying and limits skin infections. But when sebum can't drain, it builds up and actually becomes a culture medium for bacteria.
As
pimples develop, the skin may become inflamed. This inflammation may
last for a time even after a pimple bursts or heals (you shouldn't
squeeze pimples, because squeezing can lead to more severe skin
infections). In severe cases, scarring may take place, caused by
imperfections in the inflammatory response to infection. It is not
known why some people are more susceptible to acne scarring than
others. Fortunately, most acne spots and inflammation heal over time,
but the healing process can take months.
