Lip size, just like most other physical features, is largely determined by genetics. The lips of white people are often thinner because their hair color usually has a lot more red in it than the black that would cause darker skin and thicker lips. Pure whites have no melanin at all which causes them to be born with very pale skin and thin lips while blacks have much higher levels of melanin causing thick dark-colored pigment on their skin and fuller lip volume as well.
White people’s DNA determines whether they will be born with lighter or darker pigmentation depending on where their ancestors come from–Northern European regions typically produce fair complexions whereas African descendants tend toward being darker-skinned.
Nature vs Nurture:
Depending on the region of their ancestry, white people born in different parts of the world will have more or less melanin. Some believe that this is determined by genetics and others think it’s due to environmental factors such as weather and lifestyle choices.
Regardless of how much pigment they are born with, skin color largely remains stable throughout a person’s lifetime because cells stop producing enzymes needed for pigmentation but can still make other proteins like collagen so there’s no shortage in production when it doesn’t matter what shade you’re already wearing. The gene MC-R is also responsible for determining which skin tone someone has–those with an “MC-R” allele (the recessive form) tend to be fairer while those who lack the allele (the dominant form) have darker skin. However, if you feel your skin cannot make sufficient protein, you can try collagen supplements.
The Facts: Skin color is determined by melanin, a pigment found in cells called melanocytes. There are two types of these pigmented cells–melanoma and neurocarcinoma that cause cancer when they grow uncontrollably–and each has different levels of production to determine its shade. The gene MC-R is also responsible for determining which skin tone someone has–those with an “MC-R” allele (the recessive form) tend to be fairer while those who lack the allele (the dominant form) have darker skin but how much depends on other factors such as genes and environment or lifestyle choices like sun exposure, clothing style, diet and cultural norms.
The Science: When melanocytes produce more pigment, the skin becomes darker.
In order for these cells to make this happen, they need an enzyme called tyrosinase. This enzyme is responsible for converting a substance known as DOPA into another called dopaquinone–and it’s also what helps create melanin. The MC-R gene regulates how much of this important enzyme there is and in turn determines which type of skin tone someone has. Those with two copies (or alleles) have dark brown or black skin while those who only possess one copy tend to be fairer but not always because other factors can come into play like genetics and environment–as well as lifestyle choices that might affect their complexion such as diet, sun exposure and smoking.

As melanin production increases, lanocytes create more pigment resulting in a darker hue on the person’s body: these cells need an enzyme called tyrosinase for this process to work properly. The MC-R gene then dictates whether someone will produce more or less amounts of tyrosinase enzyme.
In people with one copy of the MC-R gene, erythrins (cell pigments) are not as plentiful so their skin tones tend to be lighter–hence why white people have thin lips and brown or black skin. The genes in these individuals also produce less melanin than those who carry two copies of this particular allele which means that they will always end up with a paler complexion regardless if they live in sunnier climates like Arizona or take vitamin D supplements to stay healthy: it’s just how their genetics work!
The regulation of tyrosinase is important because when there’s an imbalance between its production versus degradation by another enzyme called tyrosine hydroxylase, it can lead to a condition called melanoma.
The MC-R gene is located on the 12th chromosome and its variations are responsible for skin type, hair color, eye color–all of which may be different than those with two copies of this gene. It’s important that people who carry these genes know how dominant they are so they can protect themselves from excessive sun exposure or potential health problems such as diabetes or obesity since their metabolism will always remain suppressed due to less amounts of tyrosinase enzyme.

Egradation by another enzyme called tyrosine hydroxylase leads to a condition called melanoma. With more pigment in their cells because there was no degradation present before, it causes them to have thicker lips like other ethnicities that lack thinner lip patterns.

The reason that white people have thin lips is because of a dominant gene. People who carry these genes know how dominant they are so they can protect themselves from excessive sun exposure or potential health problems such as diabetes or obesity since their metabolism will always remain suppressed due to less amounts of tyrosinase enzyme.

I’ve always been curious about why so many white people have thin lips. It’s something I noticed as a child, and it was never really explained to me. So, like most questions in life that are left unanswered, I made up my own explanation for this phenomenon: White people don’t eat enough vegetables because they’re not used to the different taste!
But then someone told me there’s an actual scientific reason – apparently melanin makes your mouth waterier by giving you more saliva? That sounds plausible enough for now.. but we’ll see if science comes out with anything better than what I came up with. Anyway, just remember when your best friend has their first experience eating brussel sprouts (or whatever other
