One of the disadvantages of tattooing is that the skin is the first line of defense of the 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 all kinds of stimuli decline, especially prone to bacterial infection. Most tattoo artists don't know medicine, and the 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 and impetigo. If the wound area is large, the bacteria are virulent, or even grow and reproduce in the blood, they will suffer from sepsis and endanger their lives. Disadvantage 2 of tattoo: The disadvantage of tattoo for individuals is that it may be difficult to find a job if it is tattooed in a more obvious part, because some work units refuse to admit people with tattoos. Disadvantages of tattooing: There are many kinds of pigments used in tattooing, many of which are chemicals. These chemicals will cause dermatitis and allergies when entering the human body, and even make local itching, pain, burning sensation, numbness, etc., and some will lead to cell mutation, which is a prelude to cancer. Moreover, it is extremely difficult to get rid of tattoos. At present, a special drug has not been developed to remove them. The only way is to have plastic surgery. The disadvantages of tattoos are now clear to everyone. In the past, many young people liked to choose tattoos in pursuit of temporary excitement. Now, many people are distressed by tattoos. Now let's take a look at the process of tattooing, and everyone will understand the disadvantages of tattooing.

[ Edit this paragraph] Precautions for tattoos

First of all, we should 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 critical. Tattoo operators should use disposable gloves and needles, and the tattoo machine should be made of stainless steel. Tattoo pattern Second, we should know the quality of tattoo pigment. Nowadays, tattoos generally do not use dyes and inks used in tattoos, but use 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. When tattooing, you should use adrenaline to clean and stop bleeding. After the tattoo is finished, warm water should be used to scrub the tattoo, and the tattoo should be kept dry (usually lasting for one week), otherwise it will cause infection and lead to skin rot. Fourth, tattoos such as animal blood or cinnabar should not be used. Pigeon blood cinnabar tattoos are extremely dangerous. Fifth, alcohol or purple liquid medicine should not be used to treat the stabbed wound (alcohol will irritate the wound and purple liquid medicine will destroy the color of the tattoo). Sixth, you need to apply professional tattoo ointment or medical vaseline after the tattoo is completed. After 2-3 hours, rinse the ointment and blood with warm water, and 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 the tattoo is completed for a few days. Don't scratch the wound to avoid infection or discoloration. Underwear should be soft and not too tight. Eighth, No swimming or sauna for the time being after tattooing. Ninth, if you have ulceration, pus, running water, delayed wound healing or fever, please consult a tattoo artist or go to the hospital for examination. Chen Yanli, an associate professor of dermatology at HKU, said that the chemical pigments used for tattooing can easily cause irritating and sensitive dermatitis to phenylenediamine, and the affected area is itchy and causes abrasive damage. 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, head of the dermatology clinic of the University of Munich, said that if the pigment contains 1% p-phenylenediamine, eight out of ten people will be allergic. Professor Prinz warned parents that children and teenagers should not be exposed to all kinds of products containing p-phenylenediamine, and these harmful chemical dyes may cause far-reaching sequelae. Some tattoo lovers even allow the so-called "tattoo artists" to tattoo themselves with eyebrow tattooing machines and non-tattoo-specific pigments because of their lack of tattoo expertise! As everyone knows, because the torque and speed of the motor of the eyebrow tattoo machine are too insufficient, the effect of tattoo is often not to increase beauty but to add ugliness; Moreover, it may cause skin lesions due to reasons such as not mastering the depth. However, the patterns printed by non-tattoo-specific pigments are far more gorgeous than those printed by special pigments. The health threats caused by tattooing include allergic reactions to raw materials, and tattooing can lead to viral infections such as hepatitis B. Methods to remove tattoos include skin scraping, skin transplantation (plastic surgery) and laser surgery, all of which will leave scars.

[ Edit this paragraph] Precautions before tattooing

* The pain of tattooing is completely tolerable. Try to relax and cooperate with the tattoo artist when operating. * Please follow the post-operation maintenance methods of the staff after operation. * Keep enough sleep before and after operation to avoid overwork. Women should avoid menstrual period. * Requirements for scar coverage: After the scar has lasted for one year, modify the pattern to determine the modification scheme according to the specific complexity.

Tattoos are harmful to health. Tattoos originated from ancient human culture are not only brave or beautiful, but also worship or marking. Let's not judge the head and foot, but from the perspective of medical care, tattoos are a kind of harmful behavior. First of all, pricking and tattooing the human body with a needle tip is undoubtedly a kind of damage to human skin cells and nerve cells, and it is an unhealthy behavior. Secondly, tattooed needles, if not disinfected properly, can spread many diseases, and may even spread viruses such as hepatitis B and AIDS. Thirdly, after tattooing, some people with special physique often have skin allergies, pathological reactions or leave scars. As a result, they become ugly instead of seeking beauty. Finally, it is worth noting that, according to research, the tattoo pigments specially used for tattoos contain lead, chromium and other heavy metals 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.
