Description

Technical Field

[0001] The invention belongs to the field of medical cosmetology, and in particular relates to a method for cleaning colored tattoos. Background Art

[0002] Tattoos work by delivering pigment to the dermis using a needle. These pigments are stable and remain there without external interference. Many young people are interested in tattoos these days, and many rush into getting them without fully considering their career plans, lifestyles, and future prospects. However, the explicit prohibitions on tattoos for civil service exams, military service, and certain jobs force some people to remove them.

[0003] As fashion trends become more prevalent, more and more people are embracing colorful tattoos. However, tattoo pigments are stable and difficult to diffuse. To ensure a perfect image, tattoo artists repeatedly insert numerous pigment particles into the skin, depositing them approximately 1 to 2 mm deep within the epidermis. At this depth, the target tissue for tattoo pigment is a very stable component. Currently, tattoo removal in China primarily involves laser, Q-switched, or picosecond laser devices, which use the thermal effect of light to break down the pigment. However, it has been found that colored tattoos cannot be removed using light alone. Many colors, such as yellow, green, and blue, cannot be removed from the body. Colored tattoos are difficult to remove because they absorb light in a relatively narrow wavelength range. Conventional laser treatments, however, struggle to absorb the energy, making it difficult to effectively break down the pigment. Furthermore, since the surface layer of the tattoo absorbs less energy, excessive laser energy can damage deeper layers of the skin, potentially leading to subcutaneous fluid accumulation, blisters, and even scarring. Summary of the Invention

[0004] The present invention overcomes the drawbacks of the prior art and provides a method for cleaning colored tattoos.

[0005] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0006] A method for cleaning a colored tattoo comprises the following steps:

[0007] S1. Disinfect the skin by using iodine to kill bacteria on the skin. Start cooling the skin by placing an ice pack on the epidermis with a layer of gauze to lower the skin temperature to -15-20°C.

[0008] S2. Scan the tattoo area with CO2 fractional laser from left to right and from top to bottom to ensure full coverage, then apply ice to cool the area.

[0009] S3. Wipe the skin with normal saline and iodine, then spray the skin with heat-clearing, detoxifying, and antibacterial drugs, and wrap it with gauze. Reapply the drugs and change the gauze every 24 hours for the first three days.

[0010] S4. After 30 days, first perform the same operation as step S1, then scan the tattoo area with a CO2 fractional laser, then apply ice to cool the area, and finally perform the same operation as step S3;

[0011] S5. After 30 days, first perform the same operation as step S1, then scan the tattoo area with a CO2 fractional laser, then apply ice to cool the area, and finally perform the same operation as step S3;

[0012] S6. Repeat the operation of step S5 3-5 times.

[0013] During tattoo removal, laser power is absorbed by the skin, generating a high temperature. If this heat is not dissipated through the pores in a timely manner, it can lead to subcutaneous water accumulation, forming blisters and leaving scars. In step S1, the skin temperature is actively lowered to -15°C to -20°C, absorbing some of the laser heat and reducing skin damage. Furthermore, CO2 fractional lasers create pores in the skin, allowing heat to dissipate in a timely manner.

[0014] The purpose of multiple cleanings is to peel off the colored tattoo layer by layer, thereby avoiding the risk of high energy in one cleaning, damaging the skin, and causing scars.

[0015] It is a further preferred method for removing tattoos and preventing scars.

[0016] Preferably, the pulse time of the CO2 dot matrix laser in steps S2, S4, S5 and S6 is 10ms, the dot matrix laser power is 40W, the spot diameter is 0.3mm, the spot spacing of the CO2 dot matrix laser is 0.5mm, and the dot matrix area is 3.6cm 2 .

[0017] Preferably, the scanning speed of the CO2 fractional laser irradiating the skin in step S2 is 2-3 mm / s;

[0018] The scanning speed of the CO2 fractional laser irradiating the skin in step S4 is 3-4 mm / s;

[0019] The scanning speed of the CO2 fractional laser irradiating the skin in steps S5 and S6 is 4-5 mm / s.

[0020] During the first three tattoo cleanings, the CO2 fractional laser moves faster on the skin. This is because during the first cleaning, the skin is relatively intact and the tattoo pigment is dense, requiring more energy to break down the pigment, and the laser moves slowly. As the number of cleanings increases, the surface pigment is gradually broken down and metabolized, and the skin's absorption and response to laser energy changes. To avoid excessive damage to the skin, the laser moves faster during subsequent cleanings. In addition, the difficulty of pigment decomposition changes: early cleaning targets shallow pigments that are easier to decompose. As cleaning deepens, deep pigments are more difficult to decompose. If the original speed is maintained, the local energy will be too high, so the laser movement speed is accelerated to disperse the energy on the skin.

[0021] The beneficial effects of the present invention compared to the prior art are:

[0022] (1) Compared with traditional Q-switched laser cleaning of colored tattoos, the layer-by-layer peeling method of CO2 fractional laser is more effective and cleans more thoroughly.

[0023] (2) Compared with single cleaning, multiple CO2 fractional laser cleaning can achieve layer-by-layer peeling, and the cleaning effect is better and more obvious.

[0024] (3) Compared with the time of each CO2 fractional laser tattoo cleaning, the tattoo cleaning effect is better by gradually shortening the time of CO2 fractional laser irradiation of the skin in the first three cleanings. BRIEF DESCRIPTION OF THE DRAWINGS
