皮肤白与不白,主要取决于人体内黑色素细胞合成黑色素的能力。分布在人体表皮基底层细胞间的黑色素细胞,含有酪氨酸酶,经过一系列的代谢过程,最后便可生成黑色素。黑色素生成越多,皮肤就越黝黑,反之,皮肤就越白皙。 White and white skin, mainly depends on the body’s ability to melanin melanin synthesis. Melanocytes, located in the basal layer of the human epidermis, contain tyrosinase, which undergoes a series of metabolic processes that eventually produce melanin. The more melanin generated, the darker the skin, on the contrary, the more white the skin.
