Darkening chemical in skin that determines skin color?
Melanin is the darkening chemical in skin that determines skin color. Melanin is produced by specialized cells called melanocytes and is responsible for protecting the skin from UV radiation damage. The amount of melanin produced by the melanocytes determines an individual's skin color.
Why do humans become tan?
Some ultraviolet radiation from the sun (UVA) oxidises melanin in the skin which leads to its darkening. This is intended to protect the skin from further damage through sunburn.UVB exposure can lead to the production of melanin. This then creates further darkening.
What is melanoderma?

What factors contribute to the darkening of people's skin?

What causes the tanning effect?
Exposure to ultraviolet (UV) radiation from the sun or tanning beds stimulates the production of melanin in the skin. Melanin is the pigment that gives skin its color and helps protect against UV damage. Increased melanin production results in a darker skin tone, known as tanning.
How do melanocytes in the skin contribute to the process of pigmentation?
Melanocytes are cells in the skin that produce melanin, the pigment responsible for skin color. When exposed to sunlight, melanocytes produce more melanin to protect the skin from UV damage. This process results in tanning or darkening of the skin.
Can you tan while wearing sun screen?
Sun tan is caused due to the sun rays . Excessive exposure to ultraviolet rays accelerate melanin production in the skin even while wearing sun screen. And this causes darkening of the skin.
Why do weget tanned in sun?

What cause skin darkening?
It is melanin, produced by melanocytes, that causes the skin to darken which is found on the skin's epidermis. Overproduction or underproduction of melanin results to skin discoloration.That is the reason why too much sun exposure results to skin darkening - when melanocytes produce more melanin (hyperpigmentation) than they should, they turn into freckles or moles.For additional information about skin care, please check the Sources and related links section.

What happens to the melanin and or melanocytes when exposed to sunlight?
When exposed to sunlight, melanocytes produce more melanin to protect the skin by absorbing and dispersing UV radiation. This can result in the skin darkening or tanning as a protective response. Overexposure to sunlight can damage melanocytes, leading to conditions like sunburn or skin cancer.
