Matters needing attention
The essence of modern tattoos is to use high-frequency needles to pierce the ink into the skin, leaving patterns and colors. Skin is the natural barrier of human body, which will repel dye foreign bodies and cause allergic reactions.
Poor disinfection can also lead to bacterial and fungal infections in skin wounds. Tattooists have not received special medical training, and the operation is not standardized, so the risk of skin infection is high. The immature immune system of minors is more fragile.
