It's probably even worse than you think.

答案可能比你想象的還糟。

That white pus is packed with a cocktail mix of bacteria, dead skin cells, white blood cells, and an oily waxy material called sebum.

白色膿液中充滿了細菌、死皮細胞、白細胞和一種叫做皮脂的油性蠟狀物質混合物。

Under the right conditions,

在適當的條件下，

these four ingredients create the perfect storm for infection.

這四種東西造就了完美的感染溫床。

Here's how.

痘痘形成過程如下。

Inside each pore of your skin are tiny sacs called sebaceous glands.

皮膚上每個毛孔內都有被稱為皮脂腺的小囊體。

These glands secrete an oily material called sebum, which lubricates and waterproofs your hair.

這些腺體會分泌一種叫皮脂的油性物質，可以讓頭髮保持潤滑並起到防水作用。

But that's not the only thing Sebum is good for.

但皮脂的作用不僅如此。

It's also an energy source for a type of bacteria called Propionibacterium acnes.

它也是痤瘡丙酸桿菌的能量來源。

Normally, Propionibacterium acnes lives harmoniously in and on your skin.

通常，痤瘡丙酸桿菌會無害的存在於皮膚內部與表層，

But sometimes it gets out of control--

但有時它會失去控制。

and that's when the trouble starts.

而這正是災禍的開端。

When your sebaceous glands grow more active like during puberty,

當皮脂腺較活躍時，如青春期時，

they generate a surplus of sebum.

它們會產生過剩的皮脂。

The excess sebum can clog your pores.

多餘的皮脂可能會堵塞毛孔。

The pore is now a food fest for bacteria, which start to multiply out of control.

毛孔現在成了細菌的自助餐，導致其開始失控繁殖。

This triggers alarms in your body, which identifies the infestation as a threat.

這會觸發身體警報，將感染視為威脅。

So your body dispatches white blood cells to the area to fight the abnormally large cluster of bacteria.

因此，身體會派遣白血球至該區域，對抗異常巨大的細菌群。

As a result, the area becomes inflamed,

造成該區域發炎，

causing the skin at the surface to swell and redden.

導致皮膚表面變得紅腫，

Eventually, that swelling will come to a head, literally.

最後，腫脹的痘痘會到達爆發點。

Even worse, popping the pimple opens a gateway for additional bacteria on your fingers,

更糟的是，擠破痘痘會讓手上的細菌由傷口進入，

which could prolong, or even worsen the already infected pore.

這可能會延長，甚至加重毛孔感染情況。

So the next time you have the urge to pop a pimple, consider the consequences.

所以，下次有衝動想擠痘痘時，先考慮一下後果吧。
