Tattooing with needles is harmful to human skin cells and nerve cells.

Skin is the first line of defense of human body, which can resist the injury of external mechanical, physical and chemical stimuli and the invasion of pathogenic microorganisms. Tattoos damage the skin and easily lead to bacterial infections, such as furuncle, carbuncle, erysipelas, impetigo and so on. 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.

Some skin diseases, such as keloid, lichen planus, psoriasis and discoid lupus erythematosus, as well as sarcoidosis, melanoma, keratoacanthoma, wart, squamous cell carcinoma and carcinoma in situ, have been reported, many of which may be isomorphic reactions to tattoo stimulation.

4, induce skin cancer:

According to research, tattoo pigments specially used for tattoos contain heavy metals such as lead and chromium and other compounds. These colored chemical synthetic substances are potentially harmful to people's health and are one of the factors that induce skin cancer, which will lead to cell mutation and canceration.
