 　　The Science Of Acne

　　Acne: the scourge¹ of adolescence². Most people endure it at some point, and can’t wait to be rid of the combination of whiteheads, blackheads, pimples⁴, and pustules that comprise the skin condition that affects over 80% of teenagers and nearly 20% of adults.

　　What Is Acne?

　　Acne begins with the pores from which hair grows. These pores contain sebaceous glands⁵ that produce a type of oil that lubricates hair and skin. When the glands produce the right amount of oil, there’s usually no trouble.

　　But, when a pore gets clogged⁶ with too much oil and dead skin cells, problems arise. The onset⁷ of puberty in most kids involves the production of hormones⁸. These hormones cause the sebaceous glands to make excess oil. Too much oil clogs⁹ pores and attracts bacteria, which feed on the oil and begin to multiply. A clogged pore can only stand so much internal pressure before its walls break, allowing the oil and bacteria to seep¹⁰ under the surrounding skin. This gives rise to something every teen dreads¹¹: a pimple³.

　　Acne Causes

　　Contrary to popular belief, eating foods such as pizza and chocolate does not cause or exacerbate¹² acne. Whether or not a person will have acne as a teenager or adult is largely a matter of genetics: if your parents had it, there’s a good chance you will too.

　　Although there is no cure for acne, simple remedies to prevent a build-up of oil in pores, such as washing your face with soap and warm water and using oil-free cosmetics¹³, can help.

　　粉刺的学问

　　粉刺：青春期的灾难。许多人都在忍受它带来的麻烦，迫切地想要摆脱白头、黑头、丘疹、脓疱的困扰。这些问题滋扰着超过80%的年轻人和近20%的成人。

　　粉刺是什么？

　　粉刺在毛发生长的毛孔上出现，这些毛孔包含了皮脂腺，而皮脂腺能产生可以滋润毛发和皮肤的油。当这些腺体产生适量油脂的时候，通常不会出现问题。

　　但是，当一个毛孔被过多的油脂和死去的皮肤细胞堵塞，问题出现了。许多孩子的青春期伴随着荷尔蒙的产生。这些激素导致皮脂腺分泌多余的油脂。过多的油脂会堵塞毛孔并滋生细菌，细菌靠这些油脂生存和繁殖。一个堵塞的毛孔的承载量是有限的，当压力过大时毛壁会破裂，油脂和细菌会渗漏到附近的皮肤上。每个年轻人的噩梦----粉刺产生了。

　　粉刺的根源

　　不同于大众的认知，吃诸如披萨和巧克力之类的食物并不会导致或者恶化粉刺。不管是青少年还是成年人，人们产生粉刺的原因在于基因：如果你的父母有过粉刺，你很可能也会有。

　　尽管没有根治粉刺的方法，但有办法可以防止毛孔的油脂堆积：比如用温水和肥皂洗脸，使用不含油脂的化妆品。
