Luckily, there's a way to remove it with lasers.

幸好現在可以靠雷射來去除刺青

Here's how it works.

讓我們一窺這個機制是如何運作的吧！

The second the tattoo ink penetrates the skin, your immune system sounds a red alert.

當刺青用的油墨滲入你的皮膚，你的免疫系統就會發起紅色警戒

White blood cells rush to the injection site to inspect the intruder.

白血球會聚集到注射部位並偵測入侵者

Tattoo ink is often made of heavy metals that your blood cells can't recognize.

但刺青用的油墨通常含有重金屬，白血球無法辨識

So they immediately start attacking it and escorting it towards the exit: your kidneys.

所以他們會只能先攻擊墨水分子並將其送往你的腎臟

But there's a problem.

但問題來了

Your blood cells are minuscule in size compared to ink droplets.

白血球跟墨水分子比起來實在是太小了

It's like a human trying to move a gigantic boulder.

就像一個人試圖要移動一顆巨石一樣困難

Your cells can rage war for decades, but the tattoo will remain intact.

就算細胞大軍為此發起一場長達數十年的戰爭，刺青最後也是毫髮無傷

That's where the laser comes in.

但這就是雷射派得上用場的地方了！

Energy from the laser acts like a giant sledgehammer.

雷射的能量就像個大槌子

It heats up the ink in your skin, breaking ink droplets apart into smaller pieces.

它會加熱你皮膚底下的油墨，藉此將大的油墨分子切割成小分子

Now the ink is easier for white blood cells to carry away.

如此一來白血球就能輕鬆將油墨帶走了

It can take over a dozen laser sessions to help your body fully remove a tattoo.

要完全消除刺青可能要花上數十次的雷射療程

That's something to think about before you go under the needle.

所以在刺青之前千萬要好好想清楚啊！
