说到痘痘，大家都不陌生。脸上那一个个红的，白的，黑的点点包包可真让人难受，实在是影响形象啊！那么，痘痘又是怎么形成的呢？就让下文为您解释一下吧。
Zits are what happen when the oil glands in your
skin get clogged and pus is what comes out when you pop them.
But don't pop them! It only spreads infection and can make your embarrassing
zits even worse!
Zits do not care about color, sex, or age, everyone from teenagers to
grannies get zits. In fact, zits can be found on the faces and bodies of over 70
million people!
A lot of things can cause zits. Including stress, and a build-up of toxins
including infection. Stress is not just a mental state of being, it can also
affect your physical wellness. If you have an infection, it will find an outlet
through pimples.
During your teen years your body starts to do some funky things while it
grows up, including producing more testosterone (a male hormone found in females
as well as males, but in varying amounts), which tells your body to start
producing more oil. As a result, the dead skin cells mix with the oil and clog
your pores, causing zits.
There are a few kinds of zits, all undesirable, but some more than others.
When your skin is clogged up with enough skin cells and oil, you get whiteheads;
a small white bump under the surface of the skin. When it reaches the surface,
it appears black and a blackhead develops. It isn't a dark color because of
dirt, but rather from melanin pigments (the stuff that gives color to your skin
and hair).
If the wall of the pore breaks, it can become inflamed and red. If it breaks
further below the skin's surface acne nodules or cysts can form. It is important
to get these treated, unless of course you want permanent scars.
Did you know?
Chocolate doesn't cause acne. Experiments conducted at the University of
Pennsylvania and the U.S. Naval Academy found that consumption of chocolate -
even frequent daily dietary intake - had no effect on the incidence of acne.
Professional dermatologists no longer link acne with diet.
Think that only
dirty people get zits? Nope. Clean people get zits too. Bacteria (the good and
bad kinds) lurk in everyone's skin.
Will scrubbing my face a lot get rid of
my zits? Sorry Snoopy, although washing your face is necessary, stripping your
face of the natural oils cause your glands to go into hyper-drive to make up for
it, which will lead to even more breakouts! You should only wash your face
gently with a mild cleanser no more than twice a day.
