What do you think of tattoos?

Tattoos, also known as tattoos and tattoos, use colored needles to penetrate into the bottom of the skin to create some patterns or words on the skin. That is, to pierce the skin and paint the wound to make the body have permanent patterns. The practice of causing bumps, stripes and scars on the skin is sometimes called tattooing. Plain tattoos are practiced in most parts of the world, but they are not practiced by people with darker skin. It is also rare in China in the past hundred years. Many ethnic groups believe that tattoos can prevent diseases and disasters. Some ethnic groups also use tattoos to show their status, identity or membership of a certain group, but the most common motivation is probably for beauty. Tattoos originated from the custom of decorating the skin of primitive tribes around the world. That is, after the operation, an indelible pattern was left on a certain part of the body. Patterns include birds, animals, flowers or totems, scriptures, gossip and so on. Reflected their aesthetic consciousness and religious concept. In China, Gaoshan, De 'ang, Li, Dulong, Dai, Bulang, Jinuo and other ethnic groups all have tattoo customs. Tattooing precautions [edit this paragraph] First of all, pay attention to whether the equipment in the tattoo shop is hygienic. Tattooing can be called a minor operation, so the hygiene of the equipment is very important. Tattoo operators should use disposable gloves and needles, and tattoo machine should be made of stainless steel. Second, we should know the quality of tattoo pigments. At present, tattoos generally do not use dyes and inks for tattoos, but liquid plant pigments soaked in alcohol. Because plant pigments are extracted from natural plants, they are less susceptible to infection when they penetrate into the skin. Third, we should pay attention to our own protection. Use adrenaline to clean and stop bleeding when tattooing. After the tattoo is completed, it needs to be scrubbed with warm water, and the tattoo should be kept dry (usually lasting for one week), otherwise it will cause infection and lead to skin rot. Fourth, don't tattoo with animal blood or cinnabar. Pigeon blood cinnabar tattoo is extremely dangerous. Fifth, don't use alcohol or purple potion to treat stab wounds (alcohol will irritate wounds, and purple potion will destroy the color of tattoos). Sixth, you need to apply professional tattoo ointment or medical vaseline after tattooing. After 2-3 hours, rinse the ointment and blood with warm water, dry it with absorbent cotton or professional paper towel, and then don't apply any medicine. Seventh, itching, scabbing and peeling are normal phenomena after a few days of tattooing. Don't scratch the wound to avoid infection or discoloration. Underwear should be soft. Not too tight. Eighth, don't swim or take a sauna for the time being after tattoo. Ninth, if there is ulceration, pus discharge, running water, delayed wound healing or fever, please consult a tattoo artist or go to the hospital for examination. Chen Yanli, an associate professor in the Department of Dermatology of HKU, said that the chemical pigments used in tattoo are easy to cause irritation and sensitive dermatitis to phenylenediamine, and the affected area itches, causing abrasion. If the pigment stays on the skin for a long time, it will cause skin dysfunction, and in severe cases, edema and ulceration will occur. Professor Joerg Kisduhua Prinz, director of the Dermatology Clinic of the University of Munich, said that if the pigment contains 10% p-phenylenediamine, eight out of ten people will be allergic. Professor Plinz warned parents that children and teenagers should not be exposed to all kinds of products containing p-phenylenediamine. These harmful chemical dyes may cause far-reaching sequelae.
