What is the principle of tattoo?

Tattooing is the use of capillary principle, two or more tightly tied needles are immersed in liquid. Because there are thin tubes between needles, raw materials are kept between several needles. Therefore, while the needle is applied to the skin, the pigment is injected into the skin. The liquid medicine was black before it was injected into the skin, but after it was injected into the skin, it turned blue after a period of time due to the influence of melanin, so people later called it tattoo.

Related extension: Tattoo, commonly known as tattoo, is called Nirvana in ancient classical Chinese. They paint an ideal picture on people's monotonous skin, become the eternity of life, and keep memories as the most beautiful picture in life. It's not a bad guy's mark. Tattoo patterns are either words or patterns.

In fact, tattoos need to pierce the skin, causing certain bleeding. If the disinfection of related instruments is not thorough, it will easily lead to cross infection, thus spreading a series of blood-borne diseases, such as hepatitis B, hepatitis C and AIDS.

In addition, tattoos need to use pigments, and some tattoo shops may bring greater health risks if they use unqualified products. The chemicals in tattoo pigments may cause dermatitis and allergies, and even local itching, pain, burning and numbness. Others may cause cell mutation, which is a prelude to cancer.

Therefore, tattoos should be selected from institutions with complete qualifications and a certain scale, which are not suitable for minors and pregnant women. Especially people with scar constitution, because even if the best pigment is used, the effect cannot be guaranteed, and once the skin with scar constitution is damaged, it is difficult to heal, which may make the skin more ugly.
