There is a legend in the tattoo industry that after the tattoo is successful, the pigeon's blood is mixed with cinnabar and white powder. Usually, the skin color is normal and no trace can be seen, but it will appear red after drinking, sweating or excitement, so it is also called drunk tattoo or invisible tattoo. Some people pay attention to it, for example, pigeons with red eyes and feathers are purer (some even say mysteriously that white pigeons should feed meat from an early age). "Someone once heard that someone tattooed his eyebrows into two dragons, which added a bit of wildness when he was drunk or furious" is pure fart! ! ! !

Cinnabar, also known as Cinnabar, mercury sand and cinnabar, is a natural cinnabar ore, which mainly contains mercury sulfide (HgS). It is really toxic, but it can be taken orally or externally. In fact, red pigments generally contain mercury, so don't worry too much. Just don't overdo it. A tattoo artist said, "with cinnabar, most people will be allergic and their skin will fester. It will take a month or two to get well."

The first is safety and unsanitary. Animal blood may carry pathogens (bacteria, viruses and other microorganisms and parasites) to spread some diseases and even dangerous diseases. Macromolecules such as protein in heterogeneous blood may directly enter the skin and subcutaneous tissue, which may cause allergies. Second, the issue of effectiveness. Pigeons with red eyes and white feathers are not necessarily purebred than pigeons with other appearances. From the biochemical point of view, the blood composition is estimated to be similar, even if the blood of other kinds of birds or animals is degraded by skin, it is similar. Pigeon blood is similar to black dog blood. The latter is said to ward off evil spirits. Should I use it more? This cell component or biomacromolecule will definitely degrade after entering the human body, so it will not last as long as inert pigments. Of course, pigments are not always leg-colored. Although many tattooists tell customers that tattoos are permanent-generally speaking, they are good, and tattoos will change-and should deteriorate slowly-this is not my point of view, but it is a foreigner's point of view: tattoos are permanent but they are detectives over time. So if the legend is true, that is to say, pigeon blood tattoos can turn red after drinking, what is the reason? I have an explanation:

1. The effect of pigeon blood may have some sequelae even if the iron-containing heme in pigeon blood is finally decomposed and faded by the human body. But in medicine, it seems that there is no such sequela after the hematoma in the skin and subcutaneous gradually subsided. So I doubt it.

2. The role of the tattoo itself, after the skin basal layer is damaged, the scar may turn red when drinking. You may see this phenomenon in your life. After drinking or getting angry, some scars will be congested and become very obvious. Many literary works also see this description. In other words, it is not pigeon blood but the tiny scar produced by acupuncture itself that leads to this special effect. Generally, some people cut the thread with an empty needle when tattooing, but it is still covered with pigment, so there is no such effect. I don't know if any tattoo artists have done this research. He only tattooed with empty needles and observed the effect after recovery for a long time, especially after drinking. If the guess is true, there can be a safe "special tattoo". Of course, there are other possibilities, such as the combination of two factors, each accounting for a certain proportion. Of course, it is also possible that this statement is simply a lie. Later, a tattoo artist responded: I tried to tattoo with an empty needle, and it did turn pale red after drinking it, but it was not a common phenomenon! ! Excerpts from several people who have actually practiced pigeon blood tattoos. "In fact, it's not that great. A friend once tattooed me the outline of a pattern with pigeon blood. After the repair, the tattoo is red, not like people say that it can't be seen after the tattoo. But after drinking, the color will be darker, that is, the red color will be heavier, because the role of alcohol will accelerate blood circulation. In addition, it is said that it is not advisable to use pigeon blood and cinnabar as tattoo pigments because cinnabar is toxic. " So at present, the real invisible tattoo is estimated to be only fluorescent tattoo, but the safety of fluorescent pigment is still controversial. On the other hand, even the more vivid and lasting tattoo pigments of international brands, the more harmful components such as heavy metals, and the non-toxic and non-sensitized natural pigments are easy to fade and not gorgeous, which is also a contradiction that cannot be solved for the time being.
