High-frequency electronic watch hands
The principle is to use current to generate high-voltage electric sparks to burn the skin, dehydrate and carbonize it, let the skin cells die, scab, and fall off to take away the color (the same principle as the sweeper), wash the shallow color (not more than 0.2?) Scarring, because the epidermis has the function of horizontal growth, but the deep layer of color is difficult to wash off, and the burned deep skin will leave a layer called "semi-carbonized hard tissue" (just like burning a corner of paper will leave The interface like the yellow trace), it affects the deep tissue growth upwards, so in the past, deep washing will definitely leave scars.
Chinese medicine washing tattoo
Many people mistakenly believe that Chinese medicine is non-corrosive, non-flammable, safe and reliable. For example: "Demolition cream" is made from Chinese medicine, but its principle is chemical cauterization. If it is used in a small amount in the cells of local lesions, the diseased tissues can be burned and carbonized to achieve the purpose of removing moles. The effect is very good, because the amount of medicine is not large, and it does not damage the surrounding good tissues, even if there is a little Destruction, good organization is easy to repair quickly. However, if it is used in a large amount on normal skin, excessive burning will produce concave scars, and if the skin is damaged by long-term slow burning, it will cause hyperplastic scars due to continuous excessive repair.
Agent a + b in Taiwan
This method has been used in the beauty industry for a long time. It uses diluted sulfuric acid to corrode the skin. It is no problem to use it in the epidermal layer, but it will leave scars when used in the dermis layer. The principle is chemical cauterization.
Freeze color removal
Using liquid nitrogen to evaporate from "liquid" to "gaseous" at minus 169 degrees Celsius, some of the skin's moisture is taken away, causing the skin to die and renew. The disadvantage is that the liquid nitrogen is sprayed with gas, the area is difficult to control, and it is easy to blisters after infection, easy to infect and scar.
Needle transfer heat method
Select metal needles of different sizes and shapes, heat them with fire, and then transfer them to the skin. Use the residual heat of the metal to burn the skin to make it peel and remove the color. The disadvantage is that the heat, time, and depth are difficult to control. Excessive heat will cause burns and scalds, and scars will be caused to the dermis. It is also prone to blisters and infections.
Laser Tattoo
Most people think that laser washing the tattoo is fast and good, and people who have used it will know that there are many things that the laser can't do. For example, the tattoo's green, non-chemical agent coloring and other complex dyeing colors, the laser can't wash It is also difficult to wash the color that has been washed three times with the laser, but it ca n’t be washed, because the working principle of the laser is to convert the light energy into heat energy. Because the chemically synthesized black and red dyes can absorb more corresponding wavelengths Energy, so it is easier to wash off, and other colors are more difficult to absorb energy, so it cannot be washed off. The energy of the laser is not enough to affect the non-compound pigments, so it is impossible to wash away the colorants containing metal atoms. Laser can't cure "arthritis pigment poisoning allergy rejection syndrome", because the potential energy of laser will catalyze the toxic pigment, making the toxic pigment penetrate deeper and more difficult to take off.
