High frequency electronic watch pointer

The principle is to burn the skin by high-voltage electric spark generated by current, so that it is dehydrated and carbonized, so that 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.

Traditional Chinese medicine tattoo washing

Many people mistakenly believe that Chinese medicine is non-corrosive, non-flammable, 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 locally diseased cells, the diseased tissue can be cauterized and carbonized, so as to achieve 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.

Agent a+ agent b

This method has been used in the beauty industry for a long time. It corrodes the skin with dilute sulfuric acid, and the epidermis has no problem, but it will leave scars on the dermis. The principle is chemical cauterization.

Removing pigment by freezing method

When liquid nitrogen evaporates from "liquid" to "gas" at-169℃, part of the moisture in the skin is taken away, causing the skin to die and regain its weight. 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.

Heat transfer method in Shenzhen

Choose metal needles of different sizes and shapes and put them on the skin after heating with fire. Use the residual heat of metal to burn the skin, 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.

Laser tattoo cleaning

Most people think that laser tattoo is fast and good, but those who have used it will know that there are many things that laser can't do, such as the green color of tattoo, non-chemical pigments and other complex dyeing pigments, which can't be washed off by laser. The color that can't be washed off by laser for three times is difficult to be washed off again, because the working principle of laser is to convert light energy into heat energy, and because chemically synthesized black and red dyes can absorb more energy corresponding to wavelengths, it is easier to be washed off. 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.
