Why does a person's skin usually get darker in the summer?

Question

I'm looking for a scientific reason, does it have something to do with melanin? Or vitamin d? Please help! Thanks I love yall!

Answer 1

Yes, it's the melanin.

The suns rays stimulates the production of melanin in the skin as a protection against the harmful effects of the sun.

This is exactly the same reason why people who live in areas of the planet that have a high incidence of sunlight -- Middle East, Mediterranean Region, Africa. It is the amount of melanin in the skin and no other reason.

Answer 2

The sun causes melanin to make the skin darken, probably as a natural defense to protect against the sun's rays. People's skin won't get darker if they don't go out in the sun or go to a tanning booth or something. People with lighter skin have less melanin and that's why they sun burn much worse than dark skinned people. People who have little or no melanin (albinism) definitely should stay out of the sun as much as possible.

Answer 3

The increased exposure to UV radiation during summer time triggers increased melanocyte production of melanin resulting in a darker skin color...

Vitamin D has nothing to do with skin color but, since its synthesis depends on UV light, individuals with darker skin are predisposed to vitamin D deficiency since they need large amounts of UV light than individuals with lighter skin in order to produce any given amount of vitamin D...

Answer 4

yes, it's because the skin cells are absorbing the UV rays from the sun creating more melanin, a nature sunblock.
