What is the health disadvantage to having extra melanin in your body?

Ava asked:
For my biology class we get bonus points if we find out what the HEALTH disadvantage to having extra melanin (eumelanin) in the body is. I’ve searched everywhere and cannot find the answer. The only information I did find is cosmetological reasons for complications with laser surgery. But I need the health reason. Any help will be greatly greatly appreciated.

I need the major reason why it is a disadvantage.

melanin is what gives the body color, right? well, the more you have the darker one is, however, african americans are at increased risk of vitamin d deficiency related to insufficient penetration of sunlight to the skin.

As a component in the skin it protects against uv damage leading to skin cancer and also premature aging of the skin, this should be listed in the physiology text, check the index.
