Firstly, the pigment composition of human body painting is very complex, so the human skin does not have affinity for it, and the skin's contact with pigment dyes can also generate a toxic and immune allergic reaction, namely allergic contact dermatitis. The most commonly used pigment in tattoo stickers is red dye, which contains cinnabar or mercury. Yellow dye contains more cadmium, while black dye contains more carbon or iron oxide. These substances can cause allergic reactions to the skin and cause redness, swelling, and itching. However, allergic reactions depend on a person's physical condition. Some people apply tattoo stickers unscathed, while others may develop dermatitis due to their skin being more susceptible to allergies.
In addition, tattoo stickers are mostly located on the exposed parts of the human body, otherwise it would be as boring as a night trip in a brocade. However, in the scorching sun, the ability of tattoo stickers to absorb ultraviolet rays like a spotlight and burn the skin is unexpected for many people. Most boys and girls stick colored paintings on their chests, arms, wrists, navels, and other areas that are exposed to sunlight, which are already prone to sunburn. In the sunlight, the brighter and more intense the color of the color stick pattern, the more it will cause local skin to absorb more ultraviolet radiation and cause more severe burns to the skin. In addition to redness, swelling, burning sensation, and stinging in the patch area, the surrounding skin will also darken and experience peeling. Excessive scratching can also cause infection, leading to skin scabbing and scarring. If this phenomenon occurs, if the skin is severely red and swollen, it should be quickly soaked in 3% boric acid water with six or seven layers of thick gauze to wet it. For less severe cases, calamine lotion should also be applied externally.
It is recommended that those with allergic constitution should be cautious in this regard. Even those without allergic constitution should be wary of tattoo stickers causing sunburn in special environments such as when the sun is too strong. Do not make yourself cry or laugh just to look cool.
According to media reports, tattoo stickers in Taiwan have been found to have plasticizers exceeding the standard. Tattoo stickers, in order to facilitate adhesion to the skin, often contain plastic agents that cause stickiness. However, excessive plasticizers can damage the user's skin, especially children's skin, and even cause cancer.
Experts suggest that children should not use such stickers as much as possible. If they want to use them, the time should not be too long, and they should be thoroughly cleaned immediately after use. A small amount of alcohol or oil can be applied to the tattoo, and after a few seconds, a soft cloth should be wiped back and forth with water, and then rinsed with water. At the same time, citizens should try to choose stickers produced by legitimate manufacturers and avoid using them for children under 3 years old. If redness, swelling, or allergies occur after use, they should quickly remove them. In severe cases, they should seek medical attention from a dermatologist.
