Description

Technical Field

[0001] The invention belongs to the field of medical cosmetology, and in particular relates to a method for removing tattoos and preventing scars, and application thereof. Background Art

[0002] Tattoos are made by injecting pigments into the dermis of the skin through a needle. This pigment is a stable pigment and will remain in the dermis permanently without external interference. Many young people are very interested in tattoos now, and most of them rashly get tattoos without fully considering their careers, lifestyles, and future development. For example, they cannot have tattoos when they are taking the civil service exam, serving in the military, or their jobs require them to. Some people will choose to wash off their tattoos.

[0003] Tattoo removal is not a simple matter, it usually requires the help of professional technology and equipment. The most common method of tattoo removal is laser tattoo removal, which uses a laser of a specific wavelength to irradiate the tattoo area, so that the pigment particles are broken and decomposed, and then gradually excreted from the body through the body's own metabolism. However, large-area laser irradiation will cause the heat of the skin to rise rapidly, and it cannot dissipate heat in time, resulting in water accumulation under the skin to form blisters, and the skin will form inflammation. If the inflammation cannot dissipate, it will leave scars. This is also the reason why many medical institutions and hospitals will leave scars after tattoo removal. In addition, the power of the laser, the irradiation time, and the composition of the postoperative drug coating will affect whether scars will be left. Summary of the invention

[0004] The invention overcomes the drawbacks of the prior art and provides a method for removing tattoos and preventing scars and an application thereof.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0006] A method for removing tattoos and preventing scarring is provided, comprising the following steps:

[0007] S11. In the preparation stage, wipe the skin with iodine, then place an ice pack on the skin surface with a layer of gauze for 10-15 minutes to reduce the epidermal temperature to -10℃~-15℃;

[0008] S12, using a program-controlled CO2 fractional laser to leave dot-matrix pores at the tattoo site, and moving to other tattoo sites;

[0009] S13, using the method in step S11, lower the skin temperature to -10°C to -15°C, and then use a program-controlled Q-switched laser to move and irradiate the laser at a position 1 cm vertically close to the tattooed skin;

[0010] S14, irradiate the Q-switched laser for 10 to 20 seconds, and repeat steps S11 to S13 until all tattoo positions are cleaned;

[0011] S15. Wipe with normal saline and iodine, then spray heat-clearing, detoxifying and antibacterial Chinese medicine liquid on the skin surface, and then wrap it with gauze. Re-spray the Chinese medicine and change the gauze every 24 hours for the first three days.

[0012] After the laser power used for tattoo removal is absorbed by the skin, when the temperature rises to about 200°C, the heat is not dissipated in the pores in time, which will cause water accumulation under the skin, forming blisters, and leaving scars. In step S11, the skin temperature is actively lowered to -10°C to -15°C, which can absorb part of the heat of the laser and reduce damage to the skin.

[0013] The CO2 fractional laser in step S12 can open the pores on the skin in advance, allowing the heat of the skin to dissipate in time, thereby reducing blisters.

[0014] In step S13, a high-energy Q-switched laser is used to continuously irradiate the tattoo. When the light hits the skin, the skin heat can generate about 200°C, so the skin temperature should be lowered before the operation. Controlling the skin heat can reduce the degree of thermal damage to the skin, which can effectively reduce skin damage during the operation. In step S12, the array pores are reserved on the skin in advance, which can dissipate heat in time, thereby reducing the risk of scarring.

[0015] Step S14 is to timely lower the temperature of the skin to release the heat and reduce damage to the skin.

[0016] In step S15, drug care is also critical, using Chinese herbal medicines that clear away heat, detoxify and fight bacteria to prevent infection and scarring.

[0017] It is further preferred as a method for removing tattoos and preventing scars.

[0018] Preferably, the pulse time of the programmable CO2 dot matrix laser in step S12 is 10 ms, the dot matrix laser power is 40 W, the spot diameter is 0.3 mm, and the dot matrix area is 3.6 cm 2 .

[0019] Preferably, the programmed CO2 fractional laser irradiation time for skin in step S12 is 0.2s to 0.4s.

[0020] Pulse time, laser power, spot diameter, dot area and irradiation time will all affect the pores reserved for the skin. Through multiple groups of experiments, it was found that under this condition, the pores have a good heat dissipation effect and no blisters or rashes appear on the surface of the skin.

[0021] Preferably, the spot spacing of the programmable CO2 dot matrix laser in step S12 is 0.5 mm.

[0022] The spacing between the light spots is crucial, because if the spacing is too close, it will easily lead to a larger area of ​​skin damage and increase the risk of infection, while if the spacing is too large, it will not be able to dissipate heat well.

[0023] Preferably, the pulse time of the programmable Q-switched laser in step S13 is 20 ns, the power of the Q-switched laser is 15 W, the moving speed is 1-3 mm / s, and the spot diameter is 2.5 mm.

[0024] The pulse time and energy of the Q-switched laser should be adjusted. Too much energy will damage the skin, while too little energy will make the tattoo not cleaned cleanly. The moving speed should also be controlled to avoid excessive local heating.

[0025] Preferably, the spraying amount in step S15 is 0.5 to 2 cm 2 / mg.

[0026] Preferably, the method for preparing the heat-clearing, detoxifying and antibacterial Chinese medicine liquid described in step S15 comprises the following steps:

[0027] S21, mixing and grinding 1 part by mass of rhubarb, 1 part by mass of mint, 1 part by mass of coptis root, 2 parts by mass of sophora flavescens, 2 parts by mass of phellodendron, 2 parts by mass of hanshuishi, 2 parts by mass of salvia miltiorrhiza and 2 parts by mass of safflower, and then soaking them in 60 parts by mass of anhydrous ethanol for one day, and then centrifuging 3 times to obtain a medicinal solution;

[0028] S22, adding 1 part by mass of non-toxic microspheres to the medicinal solution obtained in step S21 to prepare a Chinese medicinal solution.

[0029] The following are the effects of the Chinese medicine:

[0030] Rhubarb: It can purge and attack stagnation, clear away heat and purge fire, cool blood and detoxify, remove blood stasis and promote menstruation, and remove dampness and reduce jaundice;

[0031] Peppermint: dispels wind-heat, clears the head, relieves sore throat and rashes, soothes the liver and promotes qi circulation;

[0032] Coptis chinensis: clears away heat and dampness, purges fire and detoxifies;

[0033] Sophora flavescens: clears away heat and dampness, kills insects;

[0034] Huangbai: clears away heat and dampness, purges fire and detoxifies, and eliminates bone steaming;

[0035] Hanshui Stone: clears away heat and purges fire;

[0036] Danshen: promotes blood circulation and removes blood stasis, relieves menstruation and relieves pain, clears the heart and relieves restlessness, cools blood and eliminates carbuncle;

[0037] Safflower: promotes blood circulation, relieves menstruation, dissipates blood stasis and relieves pain.

[0038] The obtained drug juice has a low viscosity, which will lead to its volatility. The non-toxic microspheres added in step S22 can carry the drug and slow down its volatility. The process of adding a thickener is avoided. If the viscosity of the drug solution is too high, the air permeability of the skin will be poor.

[0039] Preferably, the non-toxic microspheres described in step S22 are ZnO microspheres with a diameter of 900 to 1300 nm.

[0040] ZnO material is non-toxic and has certain antibacterial properties. The size of the microspheres is between 900 and 1300 nm and will not penetrate into the skin. Microspheres can also carry drugs and reduce drug volatilization. In addition, the accumulation of microspheres will also leave pores, which can make the skin breathable.

[0041] Nursing stage: On the first day, remove the gauze and wipe it clean with iodine, then wipe the iodine on the epidermis with saline. The iodine should not adhere to the epidermis and must be cleaned. After wiping it clean, start spraying the medicine. Do it once a day for the first three days. During this period, you cannot eat irritating and spicy foods. In order to prevent the occurrence of inflammation, you cannot touch raw water during this period, and you cannot scratch or stimulate the healing of the skin. You need to have a normal life and do not do strenuous exercise. You need to pay attention to personal hygiene and reduce activities.

[0042] The above method illustrates that the present invention can be applied in the field of medical cosmetology.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] (1) Compared with the existing technology, the present invention does not directly use high-energy Q-switched laser to clean tattoos, but irradiates the skin surface with CO2 fractional laser in advance to leave pores on the skin surface. When irradiated with high-temperature Q-switched laser, the heat will dissipate through the pores and is not easy to accumulate in the skin, reducing the risk of bubbles and scars.

[0045] (2) Compared with the existing technology which is based on experience and feel, the present invention systematically adjusts the laser power, pulse time, spot movement speed, dot matrix interval and other parameters to adjust a suitable parameter range, which can reduce the risk of scarring more regularly and effectively.

[0046] (3) Compared with traditional drug-assisted treatment, the present invention reduces the risk of scarring by using traditional Chinese medicine-assisted treatment. Traditional Chinese medicines that clear heat, detoxify and fight bacteria are used to extract traditional Chinese medicine liquid. Traditional ointments have a high viscosity and when applied to the skin, they will cause poor air permeability and easily cause wound ulceration. However, in the present invention, no thickener is added, but non-toxic ZnO microspheres are selected as drug carriers, which can slow down the volatilization of the drug. In addition, the accumulation of particles will leave gaps, which makes the skin have good air permeability. BRIEF DESCRIPTION OF THE DRAWINGS
