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 somefunky 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.

皮膚下面有一種分泌油脂的腺體叫皮脂腺，油脂通過一些小孔分泌到皮膚表面以保持皮膚的光滑與柔潤。毛發(fā)也是從這些小孔中長出來的，這就是毛孔。青春痘就是發(fā)生在毛孔與毛囊皮脂腺的慢性皮膚病。

青春痘也叫粉刺、痤瘡或暗瘡，主要發(fā)生在12－25歲，10個人中有9個人會發(fā)生青春痘。青春痘可以長在臉上，也可以長在背、頸和胸部。未經(jīng)治療的青春痘一般持續(xù)4－5年。

醫(yī)學(xué)研究證明，長痘的人59％存在心理障礙，其焦慮程度甚至高于牛皮癬和癌癥病人的表現(xiàn)。青春痘不僅影響學(xué)習(xí)、生活和就業(yè)，也影響青少年的性格成長，長痘的人會比較內(nèi)向和害羞。

那么，青春痘到底是怎么發(fā)生的呢？一是由于角質(zhì)層增厚堵塞了毛孔，里面的油脂排不出去，越積越多就形成一個個小痘痘。二是在雄激素的刺激下毛囊中的油脂分泌增加，加之毛孔堵塞排泄不暢，就形成了一個個小痘痘。

把青春痘簡單地分成輕中重度其實是毫無價值的，應(yīng)該分成炎性和非炎性兩種對采取什么樣的治療比較有幫助。非炎性的包括黑頭粉刺、白頭粉刺與毛孔擴大。所以，黑頭、白頭、毛孔大，這些都是青春痘的早期階段，一般屬于輕度，只要及時治療，一般不會留下斑痕。但是，如果用手擠壓，或者使用粗暴的方法也可能發(fā)炎，同樣會留下斑痕；油脂在毛孔中越積越多，痘痘越來越大最后形成面泡和膿皰，出現(xiàn)“紅腫”和“觸摸痛”，這就是炎性青春痘。 “炎性”痘痘會留下斑痕，這些斑痕不可能完全消退。所以，“炎性”青春痘要盡早治療，以免留下永久性斑痕。越早治療，越不易留下斑痕。
