1. 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 layer 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" (like burning a corner of paper will leave The interface like the yellow trace), it affects the deep tissue growth upwards, so the deep washing in the past will definitely leave scars.
2. Tattoo Removal with Chinese Medicine
Many people mistakenly believe that Chinese medicine is non-corrosive, non-flammable, safe and reliable. For example: "Demolition cream" is made of Chinese medicine, but its principle is chemical cauterization. If it is used in a small amount in the cells of local lesions, the diseased tissue 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.
3. Agent a + agent b
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 epidermis layer, but it will leave scars when used in the dermis layer. The principle is chemical cauterization.
4. Depigmentation by freezing
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 sprays gas, and the area is difficult to control. After freezing, it is easy to blisters, easy to infect and scar.
5. Shen needle transfer heat method
Choose 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 off and take the color away. 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.
5. Laser tattoo removal
Most people think that laser tattoo cleaning is fast and good, and people who have used it will know that there are many things that laser can't do. For example, tattoos of green, non-chemical agent coloring and other complex dyeing pigments, lasers can't wash It is also difficult to wash out the colors that have been washed three times with the laser and still cannot 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 be washed away, and other colors are more difficult to absorb energy, so it cannot be washed away. The energy of the laser is not enough to affect the non-compound pigments, so the colorants containing metal atom components cannot be washed away. 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.
