To all the people who are grateful to have dark skin, with the bottom of my heart i have to say you guys are best!
But everyone will say i am black it hurts a lot😭
I don’t get why everyone thinks melanin is so magical or special lol we all have it, many other animals have it. It just to protects you from uv damage from the sun. That’s why people who evolved in sunny climates have more and people that evolved in less sunny climates have less.
@@kw2519 white and black people have different types of melanin tho, and some professors has stated that eumelanin cant evolve into pheomelanin im not sure about that tho and i think no one is.
@@kw2519 u dont have it
@@the-great-awekener white is albino
When it's extremely hot and dont have sunscreen on, I tend to get darker... Now I know why😁
Hello
That's what I need to happen
This proves that people are not different colors they are different SHADES of the same color.
Absolutely!! I love the simplicity of the way this video was explained. According to the Genome project, we are all genetically 99.9% the same. I’m working on a video that shows how mutations in our body can cause a change. For example, a mutation that omits tyrosinase in the melanin producing process can cause a baby to be an albino with no tanning ability.
Yes, it all depends on the parents.
Nature is incapable of producing different skin colors it seems, just like black and white TV does not show "all kinds of colors".
Great video! Thank you. This will help eliminate racism, particularly the unfortunate and most popular form:racism against darker humans. Thanks for sharing.
this is a great video. i think it enforces evolution as well. darker people really have just evolved from places with more sunlight. seems like it's a protection mechanism.
It does to some degree. But some black people might use this to their advantage against their white counterparts. It will just be an endless argument.

There's already people thinking that their melanin gives them magic powers. It's such a shame as it only going to be used to mock them further. There are some great benefits to melanin, but most of it is only skin deep.

Victorious Ambassadors for Christ yes, that’s a terrible book.
As usual from BioInteractive, this is a wonderful and informative short animation. I will certainly share it with my students,
lol
Such a wonderful explanation in short. This has helped me understand that how Melanin production can be increased. Thank you very much. More power to you. 👍🙂
Melanin exists as three forms: eumelanin (which is subdivided further into black and brown forms), pheomelanin, and neuromelanin.
Some lack eumelanin.
The speaker, Dr. Jablonski, is one of the major experts on the evolution of upright walker’s skin. Homo Sapiens were not the only ones who went from “hairy to sweaty”, as she shows in her favorite “timeline”. There are quite a few videos on UA-cam where she tells us about our shades. The shades we come in are not races. They are adaptions to our environments.
Ok I understood just like we use shade nets for plants for the sun it's the melanin that works as a shade for our skin.
I’m pale white & got skin cancer on my face a few years ago, too much sun ☀️ no sun screen & it was a freckle on my face that turned to cancer so be careful guys stay protected x
Thank you for the honesty about your skin and the sun.
I was feeling very sad 😢 about my colour but after watching this video I felt happy 😅 that iam safe.Thanks a lot ❤️ for this video
Hai 😊
How did scientists even find this out? Lol, amazing stuff, I'd really like to know that.
Sadeq they find out through careful years and study's, by simply cutting up layers of tissues under a microscope. Lol ez bro
So beautifully explained, good job!
Thank you!
@@biointeractive I love your video, I came across this after reading about mummies
can’t believe hundreds of years of human history were affected by this scientific phenomena
The information has been corrupted and appropriated by transparent $kin people because the information doesn't correlste with their narrative of superiority. So therefore causes insecurity which is compensated for with deceit, delusions and denial. That's the essence, behaviours, psychology and traits of innate narcissism.
thank you. this video is really helpful to see how the melanin, melanocytes, melasma, keratinocytes works in our epidermis layer
Glad it was helpful!
@@biointeractive can someone change their skin from phenomelanin to eumelanin or vice versa?
In other words, Black skin holds up much better and doesn't age as quickly as White skin due to this pigment :)
I thought that had to do with the thicknesses of the skin layers, not melanin.
@Big Dick no, Melanin determines the skin tone not the thicknesss. the thickness of the skin is determine by the amount of collagen and elastin ...
TOM, your skin color has nothing to do who ages quicker, but much of a matter of protection from certain skin cancer. yes , black skin holds up much better but only from certain skin cancer .

But it protects against solar radiation and isn't photogenic skin aging play a big role? I notice a lot of dark skinned women look really young.
Melanin may be we control are or not & how ?
You can if you faced it cause of hyperpigmentation like me my stomach area is almost like a skin colour but my hands face and my lower are little dark 🙈 it's because of hyperpigmentation so to get rid of it u should drink beetrootgajar juice every day with lemon 🍋 juice one spoon 😋 every day than u will get your beautiful flawless 💗 skin back I know that I have a lightish brown skin and not pale white I hate it my skin colour is the best and I need to take care of it since I didn't used to before it has become dull I am working on it to get rid of pigmentation around my some parts of the body 😀😀
thanks for your explanation, now i understand why my skin sometimes dark and light, it depend on how much melanoid and melanoses product in my skin right?
Informative, but the video could be more specific. For example, "genetics determines both the baseline color and how much it can tan." That should have been followed by examples. What do melanin and melanosomes look like in fair-skinned people? What do they look like in dark-skinned people?
Also, there is no mention of race. What are general differences in skin composition between people of European, Asian and African descent? I know that question is politically-incorrect, but it would make the video more honest.
That is because there is no such thing as race … the difference comes from gene mutations between different ethnic group gene pools. The reason why certain groups have a similar hue of skin color is because of genetic isolation like let's say the Japanese today. This is also why they look so much alike in terms of phenotype and features. This has nothing to do with race. Europeans are an extremely mixed people in terms of genetic phenotypes which is why they have the highest mutations as far as hair color, eye, color, and skin color. They are for sure the least distinct race and are not a race of people at all as they mixed with many Asian Phenotypes for thousands of years before isolating to Scandinavia another regions where there was more genetic isolation so they look more alike now. We are extremely brainwashed. There is no such thing as race. The genetic mutations through albinism is what made us have and lose pigmentation as Homo Sapiens Sapiens (Human Beings) and those genes were passed to people looked similar to one another. This is why we look the way we do today. But animals like dogs and cats have so much more genetic mutations than we do it is crazy. This is why their hair and eye color are so different from 1 another but they are still just the same dogs and cats. And so are We !
No such thing as different hunan races. We're all the same race, the human race. Everything started in africa/middle east. The reason why people bave different skin tones is because people have moved away and branched out to different areas over time. People that have ancestry of those that come from the equator, or close to it have darker skin. If your ancestry is from colder countries where there is not much sun you don't need to have dark skin. I've also heard that having the curly hair plays a role in sub protection but not sure. But pleas everyone get this idea out of your mind that we're all "different" or that our blood is different whatever you may think.
@@MulataLinda8 races do exist it’s no longer politically collect that would be like saying our dna is 99% the exact same as bananas does that mean we are bananas? No we’re not bananas we are humans and humans have subspecies Aka Races we share 99% of that same DNA but thst 1% is what makes us unique and different if we can trace ancestry to genetic clusters then races do exists on a biological level there are 7 biological races on earth. Not the 5 social construct races based on skin color. We are different but the same.
@@SemajSemaj I am going to look up how to get unbrainwashed so I remember this. Thanks.
@@covfefe1787race doesn’t follow any biological classification. It’s arbitrary and isn’t based on genetics, this is why two people who are closesly related can be considered two separate races and more into populations they have less in common with genetically.
When we talk about genetics we are talking about populations and not races.
Suppose I live in a warm climate and have tanned ever since I was a kid.
Now if I transfer to a cold climate will the Melanocytes and keratinocytes adjust to the colder climate?
How will it effect my skin... Will the skin get lighter or will it simply stop tanning? 🤔
No it doesn't works like that. Skin pigmentation is controlled by genes. The skin colour you are born with cannot be changed like that. This is actually a case of polygeny and the effect of all the genes are additive.(don't know about the case if you try to change it by some kind of gene therapy)
@@idontcare9811 it does change, I had tan skin due to the sun and when i went to canada to British Columbia, my skin became more whiter.
dj Dryinitro, well I think that’s just because your skin isn’t getting the same amount of sunlight, so your skin is probably reverting back to its original color. You probably won’t get any lighter and will most likely stay that color unless you go back to a place with a lot of sunlight again.
It will get lighter.
@@idontcare9811More sunlight pulls more melanin to the surface of the skin, and let me add it does not provide UV protection
Hmmmm it's good being black
Bo Branche well good for you to be confident under your skin
Bo Branche i dont think so... all my friends always call me ugly because i have a dark skin
Well first of all i don't think you're telling the truth. Second of all, colorism is a social disease placed on this earth by the white man that inflicts hatred upon dark skinned people that is either personally inflicted or inflicted by others. So despite what society might think there are scientific advantages to having higher melanin but acceptance from others starts from accepting oneself.
ki Love yourself you don't need validation
Bo Branche preach they are mad because they can't be us
Melanin is best thing that has never happened on earth ...energy itself
Completely different to energy bro 😂😂 it's just an adaptation to handle UV rays for longer although at the cost of Vitiam D obsorbtion
@@marzouk6270 No it gets way deeper. I think you know that
@@marzouk6270 I sense DEEP insecurity in your comment from you. You might want to come to terms with your narcissism.
So about how long will it take to see the effects in your hair color after taking Tyrosine??
Does Tyrosine increasing or decreasing the melanin?
@@thatsme9371 increases. Lack of tyrosine causes albinism
Thak you melanin for saving our ancestors from and me from deadly diseases unfortunately our European cousins lost their ability to produce melanin 15000 years ago may God protect them from these nasty diseases 🙏.
Dark skin died out in your Europeans cousins because dark skin was getting them killed by deadly diseases cause by vitamin D deficiency. It’s probably best to know atleast a little bit about genetics and evolution before you talk about it.
@@TmanRock9 no
@@TmanRock9 you're so wrong is funny

Great educational video. I added it to our educational library for dermatology doctors. Thank you!
came here for an extra credit assignment >.>
I need to learn this to make subliminals
Hi army and blink
What happened to the stopping points? These are essential for it to be considered an interactive!
@ tom schneider
We have an interactive version of the film at www.biointeractive.org/classroom-resources/interactive-exploration-how-we-get-our-skin-color
I remember learning about this in school
Thank you very much, I think the melanin or sun light absorption can or should be more in East due to its exposure to Sun light, than in west..and Sunlight can or should be equally distributed with careful and meaningful usage of earth resources
Yep connect sun n nature
3:21 I’m Turkish and I when I tan my colour looks like the middle of the image between white and black. I mean it’s a bit lighter than that but I don’t know why I don’t tan more.
Yes because we are natural people aka the real ‘“gods” people”’
There is a limit to everything
White is albino
@@decoloniz_afro Lol no, if all whites were albino then there wouldntt be individual whites who get diagnosed with albinism.
That's the limit to which your skin can protect, exposure to more sun can damage the cells.
this youtube video may not have its own pigment, but the quality sure is good
Very informative and helpful! Thank you very much :)
You're very welcome!
I'm so grateful I'm not white thanks melanan
Who do some people don't understand 😢that dark skin not bad
Because they are willfully ignorant.
lizard at beginning is very cool
I found the reason of racism
You certainly found a crucial yet partial reason for racism/w.supremacy.....it goes even deeper than this, I've intensely studied this for 17 years
Request to submit this video to the US Supreme Court.
why
Thats THEIR powers again.....why don't we submit this info to each other and do what is best with it? Do you think we should do for ourselves what we expect others to do for us?
@@-ucanthandledatruth01-12 its cringe to make each other aware of things.
Fascinating!
So tanning is a defense mechanism against cancer
loved it great info. UA-cam rabbit hole surf'n. You never know what your going to come across.
This is very educational for me to see this. 😀
they don't want us to know about Ur own body
Skin colour and fairness creams and cosmetics for reducing excessive tanned skin . And rejuvenation. And age defying complexion.
wonderful ...... thank your for such great animation I could understand better this concept !!
Thank you this is accurate as a actual medical student thank you for this accurate depiction it seems people only believe skin melanin is brown when it's black , yellow and red. The amount of these pigments is relatively the same the difference is the shape when we are talking about variations of skin shades.
Those pigments are all various shades of the color brown actually. Melanin is actually various shade pigments of the darkest of dark brown (even if looks black to our eyes) to the lightest pigments of Brown. Very similar to wood. Even what we call "Red" hair from genetic mutations is a varied pigment shade of the color Brown. I look at Melanin under electron microscopy on a pretty daily basis under the epidermal layers of the skin. It is insanely fascinating. All varied shades of vast varied percentages of Pheomelanin and Eumelanin dots give us our varied different skin complexions and hair colors, we see the same under microscopy for Dog and Cat hairs also.
INFORMATIVE
Let that sink in ..we ALL have melatonin....kinda cool when you think about it smile 😊
It’s like transitional lenses but for skin, pretty cool
And excessive oil skin . For acme and pimples reductions.
My trypophobia just skyrocketed to a whole different realm....
Can anyone explain how it affects the nervous system
Correcting you. Blacks are low on Vitamin D levels IF they live in locations which do not provide them with enough sun exposure.
@@GospodinJean Well said!!
Can someone tell me how to remove melanin completely from my body please😭😭😭😭
why
You're married to it....but you could have affairs and cheat against it. You could even pretend its something else you're married to to be honest.
Or burn it with bleach products.
Such a terrible shame you think this way but there are many of you, I'm *NOT* with you but you're not alone.
Racist
@@-ucanthandledatruth01-12 burning melanin isn't good for skin right? Wont there will be increased chances of skin cancer with it?

Don't hate yourself I bet you look poppin'
Our body is the great blessing of GOD don't hate it 🤗
I was lighter as a child but I tanned as I grew up coz I would play sports....now I have become a shade lighter but I would love to get my original tone back
U are albino then

Mr Penguin Do correct me if I'm wrong. So your last example with having 2 black parents and being white is an example of mutation of genes? or does mutation have nothing to do with the genes and is a separate thing?
Mr Penguin 👏👏👏👏👏
Summary: There is a pigment called melanin. It is found in humans, and also many other animals (and even fruits/veggies). It is related, in plants, to the pigment chlorophyll. There are three main types of melanin: eumelanin, pheomelanin, and neuromelanin. Eumelanin is found in the skin. It is initially produced in the epidermis' bottom layer aka "basal layer" scientific name: stratum basale, but later transports to the top layer of the epidermis (that layer is called the cornified layer (stratum corneum) The human (and animal) top layer of skin, aka epidermis, is an example of epithelium. Our palms and souls of feet have the largest layer of cornified layer (stratum corneum). Interestingly, even though darker humans usually have darker skin, on the palms of their hands and souls of their feet, the tone is very close to that of light skinned humans. Racism is a misnomer since we are all the same race homo sapien sapien. I hope this info helps you and other individuals seeking knowledge, wisdom and insights.
you have skin bit make color u get skin color magic magic
Great video
So all my head including my neck are brown af but then the neck down im white how come?
Same
Hyperpigmentation from the sun.Use sunscreen.
You think it would be simpler to put the melanocytes in the top part of the epidermis. Is there any evolutionary advantage to putting them at the bottom?
Roedy Green
There is a good reason why melanocytes dwell at the bottom and that is because the tissue around them are Avascular ( or have no blood vessels ) .Melanocytes need nutrients from the blood to continue producing melanin so that's why it stays as close to the bottom ( were blood vessels are ) as possible for it to continue its function.
This is also why your skins cells closer to the top are dead cause they don’t have access to nutrients , but they don’t need to be alive to carry out their main function which is to be a barrier.
I don't really like summer because I can't take the heat. I hate when the temperatures get so high. That's why I rarely go outside. I'd rather be in the house where it's cooler.
Thank you that answered all my questions
is it possible to change your skin tone naturally?
No
No
beautiful and wonderful explanation 👌❤
