But then go to the tattoo artist who used to tattoo you to fill in the color. The advantage of tattoo is that more and more people are beginning to face up to this art and regard it as a private symbol of art, fashion and personality, and use it to vent their inner feelings and publicize their personality.

The disadvantage of tattoos is that

1, tattoo needles will spread many diseases, even hepatitis B, AIDS and other viruses if they are not disinfected.

2. Some people with special physique often have skin allergies, pathological reactions or scars after tattooing. As a result, they became ugly instead of pursuing beauty.

3. Tattoo pigments for tattoos contain heavy metals such as lead and chromium and other compounds. According to research, these colored chemical synthetic substances are potentially harmful to people's health and are one of the factors that induce skin cancer.

Extended data

From a medical point of view, tattooing is a harmful behavior. Skin is the first line of defense of human body, which can resist the damage of external mechanical, physical and chemical stimuli and the invasion of pathogenic microorganisms, and plays an important role in human health. Tattoos, on the other hand, destroy this line of defense, making the human body's ability to resist various stimuli decline, especially prone to bacterial infection.

Hurt one? Most tattoos are not strictly disinfected or not disinfected at all. When the needle tip pierces the skin, bacteria and other pathogenic microorganisms are brought into the body, causing various infectious diseases, such as furuncle, carbuncle, erysipelas and impetigo. If the wound area is large, the bacteria are highly toxic, and even grow and multiply in the blood, they will suffer from septicemia, which is life-threatening. The risk of tattoo infection is the biggest factor that the American Blood Bank Association requires tattooers to wait for one year before donating blood.

Injury two? People with tattoos are not allowed to lead state-owned enterprises or institutions in China. If the tattoo is washed off, the only way is plastic surgery. However, because the tattoo was originally caused by burning the skin with laser or medicine, no special medicine has been developed to repair it without leaving traces. The only way is plastic surgery.

Injury three? There are many kinds of pigments for tattoos, many of which are chemicals. People with poor health are prone to dermatitis, allergies, and even local itching, pain, burning and numbness. It is easy to cause common skin injuries, such as permanent allergy, keloid formation, granuloma, magnetic resonance imaging complications and so on.

The toxins in the ink of the injured tattoo may cause cancer after being absorbed by the human body. The nanoparticles in tattoo ink will gather in the spleen and kidney after entering blood vessels, which will affect the detoxification function of the body. Some tattoo inks are rich in cobalt and mercury, but some tattoo inks used in the market now have no product description and ingredient list, so users know nothing about the potential dangers when tattooing. ?
