Chemical peeling is one of the widely used freckle removing methods several years ago. This method has been tried in many forms in China since ancient times, such as stripping with caustic soda. However, due to the limitation of technical conditions, further pharmacological research cannot be carried out. The United States did not formally propose it until 1962. This method was first adopted by dermatological surgery, and later people used this method to treat spots, which is what we often hear in the beauty industry. It mainly uses chemicals to corrode the skin surface, causing contact dermatitis. When the scab falls off, the damaged skin disappears. In fact, "skin-changing therapy" is to achieve the purpose of freckle by forcibly peeling off the stratum corneum. Commonly used chemicals are benzoic acid, salicylic acid, trichloroacetic acid, fruit acid, flower acid and so on. Because this method has the characteristics of clear treatment target, relatively clear indications, short treatment time, quick effect, low cost and simple use, it was widely used at one time. But with its side effects, this method has disappeared.
(2) Mechanical stripping method
Mechanical peeling, like chemical peeling, is also one of the widely used freckle removing methods. Its main feature is to achieve the purpose of freckle removal by burning, freezing and grinding pigmented skin. Commonly used methods are:
(1), laser nevus removal
A principle
Laser instruments produce high-intensity beams, and different types of lasers can produce different colors of light. The naked eye color of laser is the key to treatment. Different colors of laser are absorbed by different colors of skin, and dye particles are decomposed and vaporized by laser energy, sealing blood vessels, and then the dye particles are absorbed by the body and excreted, and the pigment disappears.
Because the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Only diseased cells can absorb specific laser, while normal skin tissue will not be damaged, so it will not leave scars. Advanced laser technology can also control the depth of laser reaching the skin, and adjustable pulse can minimize skin damage. Generally, the skin can return to normal within 7 days to 10 day, without affecting people's normal life. During the operation, the treatment time is only a few minutes at a time, and at most it is ten minutes. After each treatment, the skin goes through a metabolic process of natural absorption, so the treatment interval is generally 2 ~ 3 months. According to the size, quantity and depth of pigment and vascular diseases, some treatments can achieve the expected effect once or twice, and generally it takes 4 to 6 times to completely solve the problem.

3045 Q-switched dual-wavelength medical laser beauty instrument outputs 1064 nm and 532 nm, and 1064nm Q-switched laser has strong penetration and can reach melanocytes or black-blue dye particles in deep skin. Q-switched laser at 532 nm can be well absorbed by black-red pigment and can effectively remove black-red pigment. So as to completely remove the pigment.
(2) ultra-high frequency therapy
Ultra-high frequency therapy is the use of ultra-high frequency current, which acts on the spot to produce high fever and gasification, and directly strips the superficial tissue to achieve the purpose of freckle removal. Although UHF therapy has the characteristics of high frequency, short wave length, strong penetration, easy to master and use, clear field of vision during operation, small wound and fast healing, expensive equipment has affected the wide application of beauty salons.
(3) grinding treatment
Dermatization, also called scraping, is a beauty technology that has developed rapidly in China. There are three kinds of grinding treatments: sandpaper friction, wire brush friction, silicon carbide grinding head and stainless steel olive grinding head, each with its own advantages and disadvantages. The "stainless steel olive grinding method" is widely used in cosmetic surgery. This method uses the high-speed rotation of the grinding head to grind away moles, so as to achieve the purpose of removing moles, which has the characteristics of lasting curative effect and obvious effect. However, due to the difficulty of operation and strong technology, it is mostly used in plastic surgery in hospitals.
(4) liquid nitrogen freezing
Liquid nitrogen freezing technology is a new technology in the field of modern therapeutics. Cryotherapy is a comprehensive effect of cryobiology. Normal cells will be irreversibly damaged when they are extremely frozen. Its combination with beauty is also a hot topic in beauty salons, which is often used to treat freckles. After freezing, freckles will appear red papules, and separate blisters will form in about 3 hours. At this time, protein will freeze to death. After 3 days, the blister dried up and scabbed, and after 1 week, the scab skin fell off and the freckles fell off. Liquid nitrogen is widely used in beauty salons because of its ultra-low temperature of-196℃, colorless, odorless, tasteless, non-toxic, olefin-free, unexposed, easy source and low price.
Using the above peeling method to remove freckles has the characteristics of quick effect and wide application range, but practice has proved that the sequelae of this irritating treatment method can not be ignored. In particular, the problem of postoperative "pigmentation spots" is not easy to solve. In many cases of beauty complaints, many of them are getting darker and darker because of long-term dependence on some peeling cosmetics, which leads to repeated mechanical operation or allergic infection. Beauty salons should try not to use spot removal treatment unless they have to. When it must be adopted, we must pay attention to the later protection.
(3) drug therapy
In addition to the common oral administration of Ve and Vc, the vast majority of western medicine drugs for the treatment of nevus are for external use. These drugs for external use are often used as effective ingredients in cosmetics for removing moles. Commonly used effective components are arbutin, kojic acid dipalmitate, ascorbic acid, ellagic acid, fat-soluble extract of hay, glucosamine and so on. The freckle removing effect of these topical drugs is mainly achieved by inhibiting tyrosinase activity. Removing moles in traditional Chinese medicine is one of the important contents of beauty in traditional Chinese medicine and an important part of traditional Chinese medicine. In the diagnosis and treatment of nevus, traditional Chinese medicine often adopts methods such as dredging and conditioning, external rubbing, external application, fumigation and washing, supplemented by meridian and acupoint massage, acupuncture and catgut embedding. It can be roughly divided into two categories: drug removal and non-drug removal.
(A) Chinese medicine to remove moles
Removing moles with traditional Chinese medicine refers to the treatment of regulating viscera and balancing yin and yang with traditional Chinese medicine under the guidance of traditional Chinese medicine theory, so as to achieve the purpose of removing spots. There are three methods: activating blood and removing blood stasis, soothing liver and regulating qi, warming yang and tonifying kidney. Commonly used drugs are: peach kernel, safflower, Rhizoma Sparganii, Rhizoma Curcumae, Rhizoma Chuanxiong, Radix Paeoniae Rubra, Radix Bupleuri, Fructus Aurantii, Rhizoma Cyperi, Radix Curcumae, Radix Paeoniae Alba, Pericarpium Citri Reticulatae Viride, Radix Glycyrrhizae, Radix Aconiti Lateralis Preparata, Cortex Cinnamomi, Rhizoma Dioscoreae, Fructus Corni, Semen Cuscutae, Colla Cervi, Fructus Lycii, Radix Angelicae Sinensis, Cortex Eucommiae, Coicis Semen, etc. Optional ingredients: Tongqiao Huoxue Decoction, Taohong Siwu Decoction, Xiaoyao Powder, Gui You Pill, Guifu Bawei Pill, etc.
(2) Non-medicinal Chinese medicine to remove moles
Non-drug Chinese medicine for removing nevus refers to a treatment method that achieves the purpose of removing nevus without using drugs under the guidance of the basic theory of Chinese medicine for beauty. It includes acupuncture therapy, qigong therapy, diet therapy and so on.
(1) Acupuncture therapy is to stimulate a specific part of the human body-acupoints to play a benign role in regulating meridians, or to regulate the functions of yin and yang, qi and blood, and viscera through the transmission of meridians, so as to achieve the purpose of removing spots and moles. In Belgium, ear acupuncture therapy and ear tip bloodletting therapy, which are often used now, belong to this category.
(2) Qigong therapy Qigong therapy is an ancient health-preserving exercise method, which is based on self-exercise techniques such as "guiding", "resting", "regulating spirit", "regulating qi" and "regulating shape" to dredge meridians, harmonize qi and blood, coordinate viscera and balance yin and yang, and achieve the purpose of skin care and removing moles.
(3) Dietotherapy Dietotherapy is a branch of Chinese medicine, and it is also a method to prevent moles by applying the cold, hot, warm and cool (salty, light, sweet, bitter and pungent) of diet to the human body. Under the guidance of the basic theory of traditional Chinese medicine, we should master the principles of "dialectical feeding" and "dialectical feeding" when choosing diet therapy to remove moles. According to the author's 30-year medical beauty work experience and research experience on pigmented spots, it is considered that western medicine mostly adopts external treatment to treat symptoms. Although it has the advantage of quick curative effect, it has obvious toxic and side effects and unstable curative effect. Traditional Chinese medicine (TCM) treats nevus by internal adjustment, mainly by radical treatment. Although the side effects are small and the curative effect is relatively stable, the curative effect is slow. Therefore, the combination of traditional Chinese and western medicine is an effective method to remove moles. The so-called "conditioning beauty" is simply "internal adjustment and external treatment, comprehensive management".
