The history of tattoos can be traced back for thousands of years. It has existed since ancient times and has never died. Maybe you don't have a tattoo, but friends around you always have one or two who like tattoos. Today, let's talk about why tattoos can stay on the skin for so long, and there are many ghosts recommended by unscrupulous merchants for semi-permanent tattoos.
There are many ways and materials for the coloring of tattoos.
For example, various minerals and plants are its raw materials
After thousands of years of development and maturity of technology, the synthesis of tattoo pigments has become better and better.
Tattoos have always been called tattoos because the tattoo color was mainly blue-black at that time. Due to technical problems, the black color at that time changed from black to blue after a period of penetration into the skin, so it was tattoos. Nowadays, this is basically not the case for tattoo pigments. Black is black.
We don't care how many formulas of tattoo color. All we need to know is that the color produced by solid pigments is the accumulation of colored particles. The tattoo is to blend the colored particles in the pigment into the skin and let it suspend between the epidermal layer and the dermal layer. Let the skin lock the color particles for a permanent effect.
Skip skin knowledge:
The thickness of human skin is generally 0.5 ~ 4mm (excluding subcutaneous adipose tissue). The thickness of the epidermis is large, ranging from 0.07 to 1.2 mm, the palms and plantar feet can reach 0.8 to 1.4 mm, and the elbow socket is only 0.3 mm. The thickness of the epidermis of the eyelids is less than 0.1mm. Generally, the thickness of the dermis ranges from 0.4 to 2.4 mm, and the dermis on the back is 30 to 40 times thicker than the epidermis. There are significant individual differences in the overall thickness of the skin. The average thickness of adult male skin in China is 1.15mm, which can vary greatly depending on the location. For example, the back and hips of the trunk are thicker, about 2.23mm. Thin, about 0.5mm. The same limb is thinner on the inside and thicker on the outside, such as about 1.13mm on the outside of the thigh and 0.95mm on the inside. In addition, the thickness of the skin at the same site varies with different ages, genders, occupations, and types of work. Adult skin thickness is 3.5 times that of newborns, but by the age of 5, children's skin thickness is basically the same as that of adults. In addition, women have thinner skin than men, and older people have thinner skin than young people.
The thickness of the human epidermis varies, and the thickness of the epidermal layer varies with the position of a person at different ages.
Making semi-permanent tattoos can't accurately grasp everyone's skin differences,
Even a beautician with a lot of work experience cannot make a perfect semi-permanent tattoo at all.
Some friends may ask, since the skin depth is different, why is the tattoo artist confident in making the tattoo design?
纹身 Because tattoos seek permanent effects, experienced tattoo artists can feel slight changes in the skin after the needle is inserted.
Therefore, the corresponding technical adjustments are made to fully retain the pigment.
Although skin cells have a life span of two to three weeks, why do tattoos last? It's like the recent Black Panther movie. The tribe's logo is the blue tattoo mark on the inner lip. This is not a wild imagination, but a scientific basis. Tattoos can accompany you throughout your life without dying. So the so-called semi-permanent is no longer worthy of a tattoo in this regard.
Tattoo needles take a small amount of pigment and bring them into the skin through the frequency of 50-3000 spines per minute. The tattoo needle penetrates the epidermis and penetrates into the dermis layer, leaving small holes in the dermis layer, and the operation of our own capillaries allows the pigment to be permanently retained and displays the pattern through the epidermis layer.
Under your body's self-healing function, the tattoo pigment will be locked firmly. It's like a sticker hidden under your skin.
One radish, one pit, one pigment and one hole. When tattoo needles cause trauma to your body, the macrophages in your body will block the trauma one after another, it is like a piece of glass. Although the wound was repaired, it left an artistic window.
For your body, the pigment particles belong to the foreign population, and the locals will inevitably exclude them or even send them to clear them. However, it takes a long time to remove, and this time gives the opportunity for colorant particles. Without clearing them, they will quickly integrate into the collective. Being plunged into the gel skeleton of the dermis layer is just like the countless immigrants who have accumulated over the years and bought a house in the local area.
Wait until the skin is repaired and healed completely. Injured epidermal cells fall off and new cells that do not contain pigment are replaced. The pigments hidden under the epidermis will fully feedback the overall effect of the tattoo. This is why tattoos become more vivid after recovery.
