国外科学家发现原来是基因在作怪,他们发现一种名为MC1R 的基因若产生变异,会让人看起来和实际年龄差2岁。


荷兰伊拉斯莫斯大学医学中心及联合利华公司共同对“外表年龄”进行研究,他们请来2693名受试者测试MC1R 基因,发现基因之间的差异,平均会让人看起来年轻2岁。

MC1R 在人体扮演最主要的工作是制造黑色素,以保护身体不受紫外线侵害。

但MC1R 有很多不同的形态,会影响皮肤和瞳孔颜色,有些人天生一头红发也是因为这种基因。

伊拉斯莫斯医学中心教授Manfred Kayser 表示,这项发现很让人兴奋,我们终于能解开娃娃脸之谜。 不过,科学家们目前还不清楚MC1R 对外貌影响的详细运作方式。
