You can tell her the disadvantages of tattoos. For example, 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. Most tattoo teachers don't know medicine, and disinfection is not strict or not 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, 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.
