吃酱油脸上会长黑色素吗 对疤痕道理有没有影响

常有人说：吃酱油、喝咖啡会使皮肤变黑，身上有伤更不能吃酱油，否则会留下难看的疤痕。其实，这些说法都是没有科学根据的。皮肤的颜色除种族遗传外，主要由黑色素决定。

It is often said that eating soy sauce and drinking coffee will make the skin black, and you can't eat soy sauce if you have injuries on your body, otherwise you will leave ugly scars. In fact, there is no scientific basis for these statements. Skin color is mainly determined by melanin in addition to race inheritance.

首先要看伤口深不深，如果伤到真皮层了就一定会留下疤痕的，与吃不吃酱油无关。吃了酱油的话疤痕里会有色素沉淀会变得颜色很深，但是你不吃酱油的话，该有疤痕的还是会有的。

First of all, it depends on the depth of the wound. If it hurts the dermis, it will leave a scar. It has nothing to do with whether to eat soy sauce or not. If you eat soy sauce, there will be pigment precipitation in the scar, which will become very dark, but if you don't eat soy sauce, there will still be scars.

如果疤痕区域比较深，就不要吃带色素的食物，但是有些食物是自然色是没有关系的，特别是伤口在愈合期间，不要吃酱油了。

If the scar area is deep, do not eat food with pigment, but some food is natural color, it does not matter, especially during the wound healing, do not eat soy sauce.
