I don't want a tattoo on my back. Can you wash it off? Please, thank you.

Tattooing is also called tattooing, which is to remove the original tattoo on the body through certain technical means. With the rapid development of science and technology, there are more tattoo washing methods, such as A +b agent tattoo washing in Taiwan Province Province, pigment removal by freezing method, Shenzhen thermal method, high-frequency electronic watch needle tattoo washing, traditional Chinese medicine tattoo washing and laser tattoo washing. Laser tattoo washing is widely used now. The principle of tattoo washing human skin is divided into shallow epidermis and lower dermis, in which epidermis can be quickly renewed and shed, while dermis cannot. Pigments in tattoos are usually implanted in the dermis, so they are permanent and will not disappear on their own. Therefore, it is not easy to get rid of tattoos. At present, the commonly used methods to remove tattoos are: 1. Laser therapy: the laser is applied to the affected area, and the pigment particles are crushed into tiny pieces, which are discharged through skin scabbing, or blood circulation discharge and cell phagocytosis to complete pigment metabolism. This method does not destroy other skin tissues and does not leave scars after operation. It is the first choice for tattoo treatment at present, but the cost is slightly expensive. 2, chemical corrosion method: it is to use diluted weak acid solution to cause superficial burns on the skin, so that the pigment falls off with the necrotic tissue. 3. Skinning method: It is to polish the skin surface with a special high-speed rotating grinding wheel to achieve the purpose of removing pigment. 4. Surgical excision: For deep tattoo patterns, the above methods are often ineffective, and only surgical excision and suture can be considered, but scars may be left. When laser, chemical etching and grinding are used for treatment, each treatment should not be too deep. If the first cleaning is not clean, the second treatment can be carried out, and the interval between each treatment should be 1-3 months. If the cleaning area is not too deep each time, there will generally be no scars left. Tattoo washing method 1, the principle of high-frequency electronic watch needle tattoo washing is to burn the skin by high-voltage electric spark generated by current to dehydrate and carbonize it, so that the skin cells die, scab and fall off, take away the color (the same as the principle of scanning), and wash the light color (not more than 0.2? ) Do not leave scars, because the epidermis has the function of horizontal growth, but the deep color is difficult to wash off, and the burned deep skin will leave a layer called "semi-carbonized scleroderma tissue" (just like a corner of burning paper will leave a yellow scar interface), which will affect the upward growth of deep tissue, so deep washing will definitely leave scars. 2, Chinese medicine to wash tattoos Many people mistakenly think that Chinese medicine does not corrode, does not burn, and is safe and reliable. For example, "Qunevus Ointment" is made of traditional Chinese medicine, but its principle is chemical cauterization. If a small amount is used for local diseased cells, it can cauterize and carbonize diseased tissues, thus achieving the purpose of removing moles. The effect is very good, because the dosage is not large, and the damage to the surrounding good tissues is not great. Even if there is a little damage, good tissue can be repaired easily and quickly. However, if it is used in large quantities on normal skin, excessive cauterization will produce concave scars, and if the skin is disturbed and damaged by slow cauterization for a long time, it will produce hyperplastic scars due to excessive continuous repair. 3. The A +b scheme of tattoo washing in Taiwan Province Province has been used in the beauty industry for a long time. It corrodes the skin with dilute sulfuric acid, and there is no problem when used on the epidermis, but it will leave scars when used on the dermis. The principle is chemical cauterization. 4. Decolorization by freezing method uses liquid nitrogen to evaporate from "liquid" to "gas" at MINUS 169℃, taking away part of moisture in the skin, causing the skin to die and gain weight again. Its disadvantage is that liquid nitrogen ejects gas, the area is difficult to control, and it is easy to blister, infect and leave scars after freezing. 5. The magic needle thermal transfer method selects metal needles with different sizes and shapes, puts them on the skin after heating with fire, and burns the skin with the residual heat of the metal to make it peel off and take away the color. Its disadvantage is that it is difficult to control the temperature, time and depth. Overheating can cause burns and scalds, and dermal injuries can leave scars, which are prone to blisters and infections. 6. Laser Tattooing Most people think that laser tattooing is fast and good, but people who have used it will know that there are many things that laser can't do, such as the green color of tattoos, complex dye pigments such as non-chemical pigments, which can't be washed off by laser, and the colors that can't be washed off by laser for three times are also difficult to wash off, because the working principle of laser is to convert light energy into heat energy, because chemically synthesized black and red dyes can absorb energy corresponding to more wavelengths. Laser energy is not enough to affect non-compound pigments, so pigments containing metal atoms cannot be washed away. Laser can't cure "tattoo pigment poisoning allergic rejection syndrome" either, because the potential energy of laser can catalyze toxic pigments, making them penetrate deeper and more difficult to remove. Precautions after tattooing 1. Avoid eating spicy, pigmented and irritating food for one to two weeks after each tattoo, and don't touch water for the first three days. Second, keep your skin dry after each tattoo wash, and don't apply any medicine to avoid skin inflammation. Pay attention to cleanliness. If there are blisters, it is a normal reaction and cannot be scratched. Third, after the first tattoo wash, the second tattoo wash can only be carried out at an interval of 75-90 days (the interval depends on everyone's skin tissue condition), and the third tattoo wash is about 90- 120 days (and so on). Fourth, customers who wash tattoos should pay attention to their own maintenance, and the process of skin scabbing and itching should not be scratched. 5. If the blisters on the skin after tattoo can't be punctured at will, they should be allowed to fade by themselves. 6. If in doubt, please consult a professional, and don't handle it yourself. [Edit this paragraph] Does it hurt to wash tattoos? Washing tattoos will cause different degrees of pain and a little blood. After all, it is necessary to puncture the skin, but this is the pain that the human body can bear, so anesthetic is usually not used, and it will affect the color and quality of the pattern. Does it hurt to wash tattoos? Related to the treatment methods chosen by patients, the commonly used tattoo washing methods at present mainly include chemical etching, laser cauterization, liquid nitrogen freezing, skin grinding, excision and suture, skin grafting and so on. The pain degree of each method is different, so patients and friends should carefully choose the method that suits them. Whether it hurts to wash tattoos depends on the patient's own situation. The degree of surgical pain is not only related to the medical conditions of receiving tattoos, but also affected by factors such as the color and area of tattoos and the number of years of tattoos. Advantages and disadvantages of laser tattoo removal Advantages: (1) Laser tattoo removal can selectively use lasers with different wavelengths without damaging the skin. This tattoo method is to inject light into the dermis, turn pigment particles into powder, increase the high jump between them, and then be absorbed and removed by macrophages. If the tattoo pattern is dark, it can be repeated many times, constantly changing the wavelength of light. Experts admit that laser tattoo will leave deep or shallow spots on the treatment site, but it is better than leaving scars and tumors. This tumor is a trace left by surgery or carbon dioxide laser tattoo. Traditional laser tattoos do great harm to the skin. ⑵. Laser tattoo can remove patterns with large area and heavy color. In any case, the final effect of this tattoo depends on the size, location and pigment used. If the pattern is small, the tattoo can be removed by surgery. If you sew well, you can hardly see it. Patterns tattooed on the neck, arms (especially deltoid, scapula, clavicle, upper humerus) and other parts with poor skin elasticity will leave scars. Tattoos can be removed with the most advanced technology. ⑶. The most obvious advantage is that laser tattoos do not need to be cut or polished, and in most cases tattoos will not leave obvious scars. Of course, the tattoo method is not a magic eraser. (4) tattoo washing does not require local anesthesia, which is another advantage of laser scar removal and other scar removal operations. Disadvantages: (1) Long time: Generally speaking, shallow tattoos can receive obvious therapeutic effects or even disappear completely after one treatment, while for deeper tattoo parts, it is difficult to completely eliminate them after one treatment, and usually requires multiple treatments. (2) Higher cost: The imported laser equipment is expensive, so the tattoo removal price is also high. (3) Color tattoos are more difficult to remove than monochrome tattoos. Dyes used in tattoos also affect the difficulty of tattoo removal. Monochrome tattoos are relatively easy to wash, while colored tattoos, such as blue and green, are more difficult to wash.
