The principle of tattooing is to use tattoo machine's needle which moves at high speed at work to pierce the skin with special pigments for coloring. The same is true of tattooing with a hand needle, that is, sticking a needle into the skin with a hand dipped in paint. However, because tattoo machine is a machine, tattooing by hand is slow, but each has its own characteristics and tastes different.

If you tattoo with professional tattoo machine and special pigments, the damage to the skin is only to prick the skin. After tattooing, take care of the tattoo according to the requirements of the tattoo artist, and there is usually no problem after recovery. However, if the inferior pigment is not only harmful to the skin, but also harmful to the body. For example, harmful metal substances in inferior pigments can cause chronic poisoning and damage health. If it is a scar constitution, tattoos are not recommended. It is difficult to recover after tattooing, and it is also difficult to ensure whether the effect of tattooing can be satisfied, because once there is a wound, the scar constitution itself is difficult to recover, let alone a tattoo that needs to pierce the skin.

The skin is not dead where the pattern is tattooed. As long as the human body is alive, the skin is alive, but sometimes people often say that the skin somewhere inside the elbow is dead, only because the nerves there are not sensitive and it is not easy to feel pain. This is not really dead skin. The metabolism of the human body exists at any time, and the extremely thin layer of skin on the surface will become "dead skin" because of metabolism, just like girls have to use things like "exfoliating cream" to remove dead skin every once in a while, while the dead skin inside is just very, very thin dander, which pierces the epidermis of the skin when tattooing.

When tattooing, because the skin needs to be punctured, a small amount of blood will flow out. After tattooing, body fluids (cell tissue fluid) and a small amount of blood will continue to seep out, and it doesn't matter after solidification. Usually, after tattooing, the tattoo artist will apply a layer of ointment on the skin of the tattooed area to protect and prevent inflammation. In the process of tattoo recovery, the skin on the tattoo site will peel off and itch, which are normal phenomena, but you must not scratch the tattoo site, otherwise it will affect the color of the tattoo. If it is serious, you need to make up the color after the tattoo is restored. You must take a bath during tattoo recovery, but you can't use irritating soap, shower gel and the like. Just wash it gently with mild soap, because it is necessary to wash off the oozing body fluids and residual ointment. Wash it once a day, and apply erythromycin ointment to the tattoo area after each wash (the advantage of applying erythromycin ointment is to prevent inflammation, and the skin on the tattoo area will not be too dry and will not form a thick scab). Don't take a bath, rub the tattooed skin hard, swim or eat seafood or irritating food before the tattoo is healed, because these will cause the tattooed skin to be red, itchy and even allergic, which will have adverse consequences on the tattoo.
