why are men darker in skin than women ?

Question

With Asians such as Indians and Pakistanis for example, you’ll see most Asian women are lighter than the men of the same race. 

Why is this the case

Answer 1

Three pigments contribute to skin color: melanin, carotene, and hemoglobin. Men and women are not born with different skin colors. It has been observed that adult human females are consistently lighter in skin pigmentation than males in the same population. This form of sexual dimorphism is due to the requirement in human females for high amounts of calcium during pregnancy and lactation.Jun 19, 2017

Answer 2

Lighter skin is considered more attractive in those countries, so women stay out of the sun and use skin products, including bleaching soap in some places. Men are more likely to work outside in the sun.
