What determines the color of your skin and what factors can affect this?

Answer 1

the differences in skin color result from differences in the amount of melanin that melanocytes produce and in the size of the pigment granules.

The three pigments that affect skin color are:

1. Melanin 2. Hemoglobin 3. Carotene

Different skin colour is simply the result of different amounts of melanin - skin pigmentation - in the skin.

For example, the absence or lack of melanin in the skin results in a person being classed as an albino.

Pigments in the skin

Skin tone in people is determined by the amount & type of melanin pigment in the skin. People with ancestors froom sunny areas have darker skin tones than those with ancestors from areas with less sunlight.

Skin color is largely regulated by the amount of melanin present in the dermis. This is determined primarily by th genotype of the organism.

Skin color is caused by the amount of melanin, or pigment, in a persons skin. This is essentially genetically decided, but some things, like sunlight, stimulate the production of melanin.

Presence of melanin pigment

Melanin is what determines your skin and hair color. The more melanin you have the darker your skin/hair will be. The less melanin you have the lighter your skin/hair will be. Melanin is passed down in your genes.

by a thing called melanin you get more melanin from the sun and less without it melanin comes from rays in the sun enhancing your pigment

The epidermis, which is the top layer of skin, has special cells called melanocytes, some 60,000 in every square inch of skin. Melanocytes produce a dark pigment called melanin. Melanin gives skin its color. Black people do not have more melanin in their system. Everyone has the same amount of melanin in them. Melanin protects the body from the damaging effects caused by the sun. When the skin is exposed to sunlight, the melanocytes produce additional melanin. This is what creates the suntan.

Some of the substances that give the skin color are melanin, blood, lipofuscin and beta carotene.

White people are not "White". Their skin is pink (which is a shade of the color Red). Their origin is in Genesis 25:25 in the Bible.

Melanin, keratin, and hemoglobin.

polygenic traits The melanin in their skin is produced in different amounts based on adaptation from where their ancestor's liv (e.g. if your ancestors lived in a hot, sunny place your body would make more melanin so you wouldn't get sunburned as easily) Your skin color really depends on where your ancestors came from. Because, if you are on the darker side, that means that your ancestors probably came from a hot place like Africa or Mexico or the Middle East, but if you have white skin, your ancestors probably came from Norway, Germany, Russia, or any place that's in the north. This all comes down to adapting to your environment.

Answer 2

Skin color has to do with the amount of melanin that a person produces, which generally corresponds to the climate that their ancestors originated from. Generally, peoples from regions closer to the equator have darker skin and those farther from it have lighter skin. Ultraviolet B radiation increases the production of melanin by melanocytes, so that both genetics and environment influence skin color.

Answer 3

The sun, heat and if you have shelter are all environmental factors that affect skin color in humans.

Answer 4
