I believe the melanin cells take in the sun rays and dissipate it as harmless heat throughout the skin, resulting in a darker pigmentation occurring or a "tanning effect", but that in no way means you shouldn't protect your skin from the sun, because too much sun exposure is dangerous.

How does Melanin protect us from the sun?
Melanin is a pigment that affects your skin to keep it the color it is. Melanin is brown. The more melanin in the skin, the darker the colour of the skin is. Melanin helps the skin by protecting it from the UV rays of the sun. Albinos are prone to a variety of skin diseases.Melanin are the cells in our skin that are colored. They are the color pigmentation that we have. The larger and closer together the cells are, the darker the skin color. When your talking about Hw, you are most likely talking about physics.
The pigment melanin and contribute to skin color?
melanin is mainly responsible for the color of skin number of melanin decide the color more the number more darker skin it protect from the sun rays and other foreign substance in white skin less melanin is there
What is melanin and why is it important?
Melanin is a pigment that gives skin its color and is released when sun touches the skin :)
Why is skin the color it is?
Skin color depends on the amount of melanin in the skin. Melanin is a pigment that helps protect skin cells form the sun and makes the skin darker or lighter. Those who have albinism have either very little melanin or none at all.
What substance in skin causes it to tan?
Skin has Melanin which is brown-colored pigment, which protects the skin from the harmful UV rays that come from the sun. When the UV rays hit the skin the skin turns darker in order to protect or shield it. Tanning or darkening of the skin is in reaction to the harmful UV given off by the sun. Consider how in warm or tropical locations such Africa, Asia, and South America people have darker pigmented skin. It is in order to protect and shield it from damage. In other words, the sun is harmful to the skin---dark or fair. When your skin tans it is in order to protect it from even more damage.
What is the function melanin?
Melanin gives color to the skin, hair, and iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production - to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.
What is melanin and what does it determine?
Melanin shields the nucleus from damage by ultraviolet radiation. It keeps this radiation from damaging the skin and DNA. It also gives color to your skin, hair, and irises. Melanin is a pigment which gives characteristic color to skin. Its main role is to absorb harmful UV radiations and protect our skin cells from damage. It determines the color of your skin. Melanin colors hair, skin, eyes, feathers, etc.
How does sun exposure affect melanin?
The variations of skin color are a result of the amount of melanin that is produced and how it is distributed. this is obvious when you are exposed to the ultraviolet rays of the sun. In order to protect your skin, melanocytes produce more melanin and, voila!, you've got a tan.
What is the advantage for melanin granules being located in the deep layer of the epidermis?
The melanin is used to protect the cell's nucleus from the UV radiation from the sun. Since the upper layers of the skin are dead, there either is no nucleus remaining, or there simply is no need to protect the nucleus, therefore melanin granules are needed only in the deeper layers of skin
How do melanocytes protect skin cells from UV damage?
Melanocytes produces melanin, the skin pigment that absorbs UV light from the sun and prevents it from damaging DNA in the cells.
What gives your skin its color?
Melanin The amount of melanin you have in your skin is determined by your genes- it is a genetic trait you were born with inherited from your mom and dad. The sun makes skin get darker. In addition- The sun's UV rays are absorbed by melanin in varying concentrations resulting in different skin colors/freckles/tans etc.... The lighter a person's natural skin color, the less melanin the skin has to absorb UV and protect itself. The darker a person's natural skin color, the more melanin the skin has to protect itself.
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.
