#blaschko lines

[kepodewers]

So, my sister gave me the idea of using Blaschko Lines on my Michael Distortion design, and it was the first good idea she has given me in months so here it goes!!

For anyone who might not know what Blaschko Lines are, in a simpler way: they’re the invisible “marks” on the skin that appear since birth, being basically molecular evidence of existence.

World idea

A world where lots of human-esque creatures live among each other, but each are very noticeably different from the other

Vampires- most of, if not all of them have albinism, this is because when they get turned their body stops aging and they are no longer able to make melanin

Werewolves- I would like to think that when they're in human form they have their blaschko lines visible, I don't have a good reason for this one. I just think it'd be neat

Those are the two that I've been thinking about, but there's so many other possibilities for this type of world and I feel like it's being overlooked

Hear me out!!

Young Spider starts painting the blue stripes on himself and Kiri being confused because "he already has stripes" which then leads to Norm realizing Na'vi eyes are able to see human's Blaschko lines.

Spider still insists on painting himself but now Kiri does it because she can trace his "natural pattern"

I suspect so! here's the story where those images came from:

and it doesn't require disease to reveal the Blaschko lines - some people's are more visible than others', and they're more likely to appear with age, sun exposure, and so forth. sounds also that they can be visible as hair patterns, and moles and such follow your markings

Imagine an alien sharing a cool human fact they just learned like ”hey guys did you know that the silvery markings on humans actually aren’t true stripes? They’re called stretch marks, they happen when the human is growing fast enough to actually outgrow their skin, which is apparently something that just fucking happens to almost all of them at some point of their life.”

and another one is like ”wait so you’re saying humans don’t have stripes.”

”actually they do, but the stripes are invisible. There’s genetic code that’d give them stripes but they’re just the same colour as the rest of the skin. So the visible stripes are not real stripes and the real stripes are invisible.”

”I swear if you tell me one more weird human thing today I’m beating your ass.”

By the way heres a cool idea for anyone that wants to make a unique human petey design:

✨BLASCHKO'S LINES✨

obviously i can't use the idea, im already using a tattoo design but if anyone wants to give petey stripes without the usual sweater or coat then here it is!

The Big Guide to Humans: Skin

First: Yes, it is true that humans have whole-body stripes that not all species can see. Yes, it is also true that they themselves cannot usually see them. They are an artifact of pre-natal development and are present from birth. They usually have no significance, though some skin abnormalities may follow their usually-invisible path (or may make them visible).

See body art for questions about deliberate skin markings.

--- Human skin is a soft yet durable covering made of stretchy proteins. It provides protection from water loss, pathogens and UV radiation, insulates their body against external temperatures, synthesizes a chemical they use to make their skeleton, and is home to humans' abilities to feel touch and to cool themselves.

The skin is made up of layers, further divided into more layers, and the different functions are distributed within them. The details of these layers are not necessary to know for working alongside humans; suffice it to say that the topmost layer may noticeably flake off in very dry environs and this is mostly harmless but irritating to the human, oozing a clear but yellow-tinted liquid (see immune system) represents a minor but disproportionately painful injury of having scraped off the uppermost layers, and bleeding (oozing or gushing a red opaque liquid, see circulatory system) means the injury is deeper still.

Skin that has been damaged can usually repair itself over time, although it may take assistance (externally binding the wound shut, for example). Deeper wounds are likely to scar, that is, to be repaired with a tougher skin of different appearance. This is not the same thing as a callus, seen on the base of human feet and sometimes on the fingers, in which the skin grows thicker and tougher to resist pressure injuries.

It is normal for tiny hairs to be present in the skin over most of the human's body, regardless of sex or gender. Both sexes may have prominent hair on their faces or torso after puberty (see lifespan and development), but it is much more common with men.

If the human is warm (likely if ambient temperature is above melting point of gallium) or has been exerting themselves, they may "sweat." Salt water will leak in small amounts from all over their skin, concentrated on the forehead/under their hair, in the soft socket under where their arms meet the body, and around the external genitalia, to make use of evaporative cooling. They may begin to smell strongly; they usually find this smell unpleasant. If the human is cold, or in some scary situations, the tiny hairs may stand up instead of laying flat. This is an evolutionary artifact from ancestors with thicker fur and no longer helps to keep them warm or frightens predators.

Humans' sense of touch is very sensitive, especially on their hands, but outside of their hands it is sometimes not precise. You could lay one of their hairs on a surface and ask them to find it by feel, and they would be able to do so with their hands even if the surface was not smooth. If you dropped a single hair on the bare arm of a human, they would feel it, but they would not be able to pinpoint its exact location without seeing it.

!! Due to tiny dangerous creatures on their home planet, humans will usually immediately attempt to remove the source of an unexpected small light touch, often by swiping at it with a hand or by jerking their body. If you are fragile or tiny, and this would damage or dislodge you, get their attention before physical contact. !!

While humans can only see a narrow portion of the electromagnetic spectrum, they can sense somewhat beyond that band with their skin. Infrared can be sensed as heat, especially at short distances. Ultraviolet can be sensed over time, as specialized molecules in the skin cause cells to sacrifice themselves to prevent it from penetrating farther into the skin. However, by the time the human has noticed the feeling of this cell-sacrifice, the skin is likely to be damaged enough that it will darken and/or become red and sensitive soon (within the timespan of a human sleep cycle). Humans with naturally darker skin can generally withstand ultraviolet radiation for longer periods of time before becoming damaged. When the darkening or reddening has passed, small brown marks called "freckles" will often remain, usually for the rest of the human's life. If the skin has reached the red stage, as the color returns to normal the damaged skin may come off in thin sheets as though the human is molting. Do not offer assistance with removal unless they ask.

Human skin is covered in bacteria, viruses, and fungi that are mostly harmless to them. This is covered in more detail under microbiome with some pertinent points under mating.

Oh this is interesting! Maybe the Taqpep is in fact involved in the Blaschko lines!

was browsing thru papers about animal coloration and learned that a gene that helps make the placenta in humans (the thing that keeps you alive when you're a fetus in the womb) also exists in cheetahs, but in the cheetahs, it just controls the placement of their spots

How does THAT happen?!

Headcanon:

After the Transcendence, Dipper can make his Blaschko's lines visible.

(For those who don’t know, Blaschko's lines are INCREDIBLY faint bioluminescent stripes that all humans have, but are only visible under UV light.)

anytime i get sad i remember that humans have invisible stripes and they look absolutely gorgeous and then my will to live comes back

[inverted-dagger]

can you imagine how fucked up the makeup industry would be if humans could see UV light. buying two different foundations to match your stripes. people painting new stripe patterns on themselves

[sarayu-sunrays]

GUYS I JUST LEARNED THAT HUMANS HAVE STRIPPPESSSSS WE ARE TIGERS WE ARE CATS WE ARE INDEFEATABLE

These are probably my favourite sticker designs so far. They were so much fun to make and I hope you all like them too!! They are up on my Etsy store where you can either buy them individually or as a pack of three <3

Oh, birthday gift inspiration!

Blaschko's lines as soulmarks

Kind of an interesting twist on the soulmates trope since people cannot see them and most people are unaware of their existence.
