1, chemical etching method

Generally, diluted weak acid solution is used to burn the skin surface and make the pigment fall off with the necrotic tissue.

2, Chinese medicine to tattoo

The tattoo removal principle of this method is to use chemical cauterization. If a small amount of cells are used for local discoloration, the carbonized target tissue can be cauterized, and the effect is very good, because the dosage is not large, and the damage to surrounding good tissues is not great, even if there is a little damage, good tissues can be easily repaired 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, high-frequency electronic watch pointer tattoo

This method burns the skin by high-voltage electric spark generated by current, making it dehydrated and carbonized, making skin cells die, scab and fall off, and taking away the color. However, because the epidermis has the function of lateral growth, it is difficult to wash off the deep color. After the burn, the deep skin will leave a layer of something called "semi-carbonized scleroderma", which will affect the upward growth of deep tissue. Therefore, it is necessary to pay attention to the deep tattoo removal, which will definitely leave scars.

4. Laser cautery

The method of laser cauterizing superficial carbonized skin tissue to remove pigment.

5, liquid nitrogen freezing method

The superficial skin tissue is necrotic and exfoliated by liquid nitrogen freezing, thus removing the tattoo tissue.

6, grinding method

Remove the surface layer of skin by mechanical method to remove the pigment inside it.

Don't treat it too deeply at a time. If the cleaning is not complete, it can be repeated. Depending on the depth of skin excision, each recovery takes 1-2 weeks, and the interval between treatments is 1-3 months. The disadvantage is that the skin may be pigmented or depilated after operation. It is difficult to completely remove the deep pigment when removing the scar left when the skin is too deep.

7. Resection suture method and skin grafting method

For deeper tattoo patterns, surgery can be considered to remove the full-thickness skin of the affected area. If the wound is narrow, it can be sutured directly. Due to certain nervousness, obvious scars will be left after operation. If the wound is difficult to suture, thin skin (cross-sectional skin grafting) should be taken from other parts of the body, such as the thigh. The disadvantage is that the color and texture of the skin graft area are poor after operation.

8. Laser tattoo removal

The principle is that the laser is applied to the affected area, and the pigment particles are crushed into tiny particles without causing skin burns, and are gradually discharged from the urinary system through blood circulation. This method does not destroy skin living tissue, leaving no scar after operation, and the effect is good.

This is a better choice to treat tattoos at present, but it is expensive.

Methods and steps of tattooing:

1. Burn and corrosion tattoos

Burning and corrosion can effectively wash away tattoos. The use of strong irritants in burns and corrosion will destroy the depth of cortex, and it is easy to store the pigments used in trauma and form scars.

2. Tattooing again (heavy tattoo)

Re-tattooing with pigment close to skin color can cover the original pigment well and achieve skin color close to skin color, but it is difficult to achieve normal skin color, and often a mixture of milk, alcohol, zinc, calcium and carbon is used.

3, surgical methods to wash tattoos

Surgery is the most reliable way to wash tattoo pigment, which depends on the location, scope, depth and pattern of tattoo, as well as the depth of pigmentation.

If the pigmentation is shallow, only from the dermal papillary layer to the papillary layer, the tattoo pigment can be removed by cutting off the skin surface layer without leaving scars; If pigmentation is deep and dermal reticular vesicles reach subcutaneous fat, the whole skin, even subcutaneous fat, must be removed, but scars will be left after operation.

4. Tattoo washing mainly depends on a laser machine.

Too many brands of laser machines have different effects. Hospitals and tattoo shops have this service, and hospital washing usually leaves scars.

Matters needing attention after tattooing:

1, just after washing the tattoo, you can apply anti-inflammatory ointment in a small area and scald ointment in a large area. Generally, it can be applied for 2-3 days, twice a day.

2. After washing the tattoo, there will be reverse color, which will appear in a few minutes to several hours due to the difference of each body and the depth of pigment. This is a normal phenomenon. In the process of later restoration, the colors will become lighter one by one until they disappear.

3. During the treatment after tattooing, it is normal to be affected by various bodies and pigments, and some will break skin, bleed or blister. However, people whose skin is not easy to heal and have diabetes should pay special attention to medication and not be infected. If necessary, they can go to the clinic for treatment.

4. Don't always rub the treatment area with your hands after washing the tattoo, and don't get wet for 2-3 days. If I am allergic to certain foods (such as seafood and spicy food), I should avoid eating during treatment.

5. Explain your situation before the treatment of scar constitution. Such guests generally recommend not to wash. If you must wash, you should be mentally prepared.

6. Pay attention to sun protection after tattooing. Guests who have been treated many times may leave traces of pigmentation. Tattoos usually appear brown or reddish after tattooing, which takes six months to one year to completely repair.

7. The treatment interval after tattooing should not be less than one month, and two months is generally recommended.

8. After washing the tattoo, pay attention to the repair of the skin. If the skin does not heal for a long time or there are infected people, you should see a doctor in time.
