African.
African and Indian skin had the highest total amount of melanin in the epidermis (t-test; P < 0.001), with no significant differ- ence between them. Amongst the remaining lighter groups, there was no significant difference in total epidermal melanin content.

Which ethnicities have most melanin?
Analysis of melanosome size revealed a significant and progressive variation in size with ethnicity: African skin having the largest melanosomes followed in turn by Indian, Mexican, Chinese and European.
Which race has the least amount of melanin?
Caucasian skin had the smallest amount of pigment and smallest melanosomes, which were mostly contained within melanosome complexes. Further findings included that melanosome size is directly proportional to the intensity of skin pigmentation, and darkly pigmented subjects have larger, wider and denser melanosomes.
Which skin type has more melanin?
dark skin
In people with dark skin, melanocytes produce more melanin than they do in people with light skin tones.
Which people have more melanin?
Dark-skinned humans have high amounts of melanin found in their skin. Melanin is derivative of the amino acid tyrosine. Eumelanin is the dominant form of melanin found in human skin. Eumelanin protects tissues and DNA from the radiation damage of UV light.
What color was the first human?
Color and cancer
These early humans probably had pale skin, much like humans’ closest living relative, the chimpanzee, which is white under its fur. Around 1.2 million to 1.8 million years ago, early Homo sapiens evolved dark skin.
Does white skin have melanin?
Very pale skin produces almost no melanin, while Asian skins produce a yellowish type of melanin called phaeomelanin, and black skins produce the darkest, thickest melanin of all – known as eumelanin.
What race has the most sensitive skin?
Asian skin
Certain skin types are more easily irritated than others. On that spectrum, Asian skin is the most sensitive while darker skin is the toughest. Eczema is more likely to arise in dark-skinned and Asian people.
Do Asians have thicker skin than Caucasians?
Asian and black skin has thicker and more compact dermis than white skin, with the thickness being proportional to the degree of pigmentation. This likely contributes to the lower incidence of facial rhytides in Asians and blacks.
Is black skin different from white skin?
Microscopic evaluation reveals that Black skin contains larger mast cell granules, and differences in stuctural properties and enzymes of mast cells compared with White skin, possibly accounting for differences in pruritus experienced by the individuals of these racial groups.
What color is Caucasian skin?
Caucasians are not always white; skin color amongst Caucasians varies widely — from pale, reddish-white, olive, or even dark brown tones. Hair color and texture varies too, with wavy hair the most common.
Can two light skinned parents have a dark baby?
The short answer is, yes! A couple can have a baby with a skin color that isn’t between their own. The long answer, though, is much more interesting. The long answer has to do with the parts of your DNA that give specific instructions for one small part of you.
What are the 3 types of melanin?
In humans, melanin exists as three forms: eumelanin (which is subdivided further into black and brown forms), pheomelanin, and neuromelanin.
What country has the blackest skin?
They found the darkest skin in the Nilo-Saharan pastoralist populations of eastern Africa, such as the Mursi and Surma, and the lightest skin in the San of southern Africa, as well as many shades in between, as in the Agaw people of Ethiopia.
What is Indian skin tone?
Indian skin tone is often defined as having a wheatish complexion, meaning it has a light brown complexion that is similar to the color of wheat. It is darker than fair or peach but is lighter than dusk. The exact hue is determined by the amount of melanin in the skin. What is this?
What increases melanin in skin?
You get vitamin A from the food you eat, especially vegetables that contain beta carotene, such as carrots, sweet potatoes, spinach, and peas. Since vitamin A also functions as an antioxidant, some researchers believe this vitamin, more than any other, may be the key to melanin production.
What is the oldest race in the world?
An unprecedented DNA study has found evidence of a single human migration out of Africa and confirmed that Aboriginal Australians are the world’s oldest civilization.
Who has the eve gene?
It is important to note that mitochondria have their own DNA that carry this particular ‘Eve’/L0 genome. This more commonly termed as mitochondrial DNA (mtDNA). It is thus nicknamed the ‘Eve Gene’ as it is an inherited gene, paying reference to the story of creation in Genesis, the first chapter of the Bible.
What is the first race in the world?
The San people of southern Africa, who have lived as hunter-gatherers for thousands of years, are likely to be the oldest population of humans on Earth, according to the biggest and most detailed analysis of African DNA.
Do you lose melanin with age?
The number of pigment-containing cells (melanocytes) decreases. The remaining melanocytes increase in size. Aging skin looks thinner, paler, and clear (translucent). Pigmented spots including age spots or “liver spots” may appear in sun-exposed areas.
Does dark skin age slower?
Darker skin can show age more slowly because it has more melanin (dark pigment that determines sun sensitivity). The more melanin you have, the more protection you have against photoaging, or skin damage from too much exposure to the sun’s rays.
