According to Japanese media reports, Japan`s National Cancer Research Center East Hospital (Kashiwa City, Chiba Prefecture) recently launched the first domestic clinical trial of [cancer photoimmunotherapy" that uses light called [near infrared rays" to treat cancer. According to reports, the treatment method was developed by the US National Institutes of Health (NIH) director researcher Kobayashi Hisakataka and others, and it was implemented by a US bio-risk company. The clinical trials have targeted several patients with head or neck cancers to confirm safety, and strive to obtain approval within a few years. Kobayashi said: "The clinical trials in Japan started earlier than expected. It can be expected that the side effects will be small and the effectiveness will be high." It is said that the method of treatment is to link antibodies that bind to many proteins on the surface of cancer cells and substances that react to near infrared rays and use them as medicines. The drug is injected into the patient, and after the cancer site is irradiated with light the next day, the drug connected to the cancer cell undergoes a chemical reaction, prompting the cancer cell to rupture. Moreover, the human immune system responds to the ruptured cancer cell components, so it is expected to be effective against cancers that have metastasized far away from the irradiation site. The report pointed out that near infrared rays are harmless to the human body and have high safety. For deep-seated cancers that are far away from t

Young people nowadays work under a lot of pressure during the day, and the rhythm is more stressful. They often sit in the office for a day, go home and work overtime at the computer and go to bed late. Sedentary inactivity is a big cause of back pain. Sitting for a long time will cause lumbar muscle fatigue, and prolonged lumbar muscle strain will result in lumbar pain. Prolonged sitting and lack of exercise have a great impact on the body's endocrine and digestive and absorption systems, which further allows the body to enter a sub-healthy state. Young people's sub-health status is not adjusted in time for many years, it is easy to cause a great burden on the lumbar spine, cervical spine, joints and other parts, thereby accelerating the aging of bones and muscles. Let your 30-year-old age 50-year-old body. Stretch your muscles and bones when sitting for a long time, and relax in a sunny place. A ray of sunshine will make you feel happy and relaxed. This is not only the psychological effect, but also the stimulating effect of light on human cells. Different types and colors of light have different stimulating effects on human cells. Blue light treats yellow bile, ultraviolet light treats leukoplakia, red light reduces inflammation and pain. Red light therapy is a new and popular way of treatment and health care in recent years, because red light has strong penetrating power, activates cells, promotes cell enzyme decomposition, and allows our cells to have a role in promoting repair, which is effective for common low back and leg pain. There is a good relieving effect. The home-type red light therapy device produced by SMIBEA. is a portable health therapy device for homes and offices. Usually you should exercise more, stay sitting for a long time, get up and exercise, do stre

According to media reports, British scientists may have found a low-cost, low-tech method to combat the vision loss that occurs during aging. In a small clinical trial they conducted, subjects over the age of 40 showed a significant improvement in vision after staring at a dark red light for three minutes a day. They report that they can see more clearly in the dark and their ability to distinguish colors has improved. Red light is often used in skin care. Theoretically, light with longer wavelengths will have a unique regeneration effect on mitochondria. Mitochondria are organelles in cells that are responsible for processing energy and keeping the body running. The wavelength of these rays is between the edge of visible light (dark red) and infrared light. Mitochondria will absorb the energy in them, and according to the above theory, its performance will be enhanced. This should strengthen the body's wound healing ability, reduce inflammation and pain, and even promote hair regeneration, depending on the location of the light. There are mitochondria in most types of cells, but they are especially abundant in the retina. The retina is a thin membrane in the eye that captures external light and converts it into information for transmission to the brain. Without the retina, we would be blind. But as we age, the mitochondria in the retina will fail much faster than mitochondria in other body tissues. Scientists believe that, in addition to other degenerative eye disorders, this is one of the main reasons for the decline in vision with aging. "However, mitochondria can absorb some forms of light, including deep red light. This is like charging a battery, which can enhance cell function. Since the retina contains a large number of mitochondria, red light is parti

If the hair loss is severe, it will make everyone feel that their own hair is becoming scarcer and scarce, and even a sloping top will appear. Most of the problems of this kind of hair loss will occur in the youth group. Hair loss is caused by high mental stress or endocrine imbalance. Even malnutrition is very likely to cause hair loss. 1. Androgenetic alopecia is an autosomal dominant gene, and its genetic characteristics need to be mainly manifested under the effect of androgen. 2. Neurological hair loss Hair loss often increases when psychological stress is too high. Under the effect of psychological pressure, the erector pili muscles of the body converge, the hair stands up, the autonomic nerve or the nerve center function is disordered, the hair follicles and papillae are changed and malnutrition, and the hair growth is inhibited, and the hair appears in the resting period. Hair loss. 3. Endocrine causes Hair growth is affected by a variety of endocrine growth hormones, so when the endocrine is abnormal, it often causes hair loss symptoms, such as after giving birth, women's menopausal hair loss. 4. Hair loss due to nutritional deficiency Hair is the main external manifestation of health. Malnutrition and abnormal basic metabolism of the body can cause changes in hair quality and hair color, severe malnutrition and even diffuse hair loss. 5. Physical hair loss The common physical factors that cause hair loss include reflective irritants and touch radioactive elements. 6. Acid hair loss Organic chemical elements can cause hair tone changes and even hair loss. 7. Infectious alopecia Infections of various pathogens are a key element in hair disorders

In recent years, there has been a great development in medicine, and red light therapy is a very typical treatment method. It can be used in all walks of life, and the actual effect is relatively prominent. Red light therapy can make protein quickly generate. It uses the basic principle of direct infrared induction, the light wavelength is relatively long, it can detect every position of the human body, and can distinguish the parts reasonably, saving a lot of time and human resources, so red light treatment has What does it do? The red light therapy instrument is a new type of phototherapy machine and equipment that can be used in hospitals and homes. Its basic principle is to obtain a bright red visible light band dominated by 600~700nm based on a unique color filter, which penetrates the body deeply , The effect is stronger. The light spot is large (equivalent to hundreds of times that of He-Ne laser), which is a stronger treatment method for curing some large-scale symptoms. The light output is divided into "strong" and "weak" grades to integrate patients with different physical fitness. main feature 1. Multi-function: standard configuration of original light output, the original light can be used for epidermal treatment, and optical fiber output can be optional, which is more integrated into the treatment of shallow cavity positions such as gynecology and

In some high-tech products, you can often see the application of infrared sensing. In fact, infrared sensing is called the light of life. It is a kind of light that is beneficial to the body. Infrared rays have many benefits when acting on the body. Improve the blood circulation system, in addition to heal joint pain, for women, infrared induction can also have the effect of skin care and beauty, so nowadays infrared physiotherapy lamps appear on the market, so do these physiotherapy lamps have side effects on health? First, does the physiotherapy lamp have any side effects? Physiotherapy lamp is an auxiliary treatment, generally speaking, there are no side effects. However, when applying physiotherapy lamps, be sure to apply them strictly in accordance with the instructions. Request timeout and too many applications may also have poor effects on the human body. However, because current household appliances have electromagnetic radiation, this type of treatment device is not easy to prevent, and the amount can be very small. As long as it is not touched for a long time, it is not easy to have big doubts, because most patients It is treatment for one or two hours, and each time is 30 minutes or so, the radiation intensity that can be touched is actually not large, and it is no lower than the radiation intensity that people who often use mobile phones touch. Second, what are the functions and side effects of infrared induction physiotherapy lamps or common problems? The infrared induction physiotherapy lamp mainly promotes part of the blood circulation system and accelerates wound repair. The injection should not be taken too close, it will burn. Implementation opinions:

Hair loss is an unhealthy manifestation, and long-term hair loss can lead to baldness. Hair loss is caused by unhealthy diet or lifestyle habits. If you eat too much oil for a long time and go to bed too late, it will lead to hair loss. Therefore, you need to have a regular diet, go to bed early, and avoid exposure to radiation. Choose a suitable wash when washing your hair. Hair water is also particularly important. 1. People with severe hair loss should stay away from too greasy, sweet and spicy foods, increase the proportion of grains, vegetables, and fruits in the diet, eat more iron- and calcium-rich foods, and increase foods that have a nourishing effect on the hair. 2. Ensure normal sleep at ordinary times, try to sleep more than 6 hours a day, develop the habit of regular sleep, and don't stay up late. 3. Too often or too little shampoo is not good, the more suitable time is 2-3 per week, and the water temperature is about 40 degrees when shampooing. Gently massage the scalp when shampooing, which can clean the scalp and make the body feel comfortable. Choose non-irritating shampoo. 4. It is best to let the hair dry naturally after shampooing. If you use a hair dryer, pay attention that the temperature of the wind should not be too high. Overheating of the wind will damage the hair tissue and damage the scalp. 5. Do not use plastic combs. The best option is to use boxwood combs and bristles brushes, which can massage the scalp, remove dandruff, and improve blood circulation. 6. Daily anxiety can cause hair loss

Red light is a kind of light source that will be used in the whole process of physical therapy. After a lot of experimental scientific research, the application of red light to the body can indeed achieve a certain therapeutic effect. The use of red light can reasonably promote the basal metabolism of the wound and improve the body's immunity. Some homes will professionally purchase red light therapy devices and use red light to achieve a certain health and health effect. Then what is the benefit of using red light to directly irradiate the wound? What is the red light Visible light is the part of light that human eyes can recognize. The wavelength of light is in the middle of 350-770 nanometer technology. The scientific research on spectrometers has a history of more than 100 years. In 1666, Isaac Copernicus discovered from the prism that the white light of natural light is composed of light of various colors, namely red, orange, yellow, green, cyan, blue, and purple. The color of the eyes of people with different light wavelengths is different. Red light is the visible light of light wavelength 600-700 nanometer technology. The spectrometer is an orderly sequence of electromagnetic radiation according to the wavelength of light, and each wavelength of radiation source has its own characteristic compressive strength. The physical of red light Different lights have different characteristics. Physiotherapy uses incoherent light with the key wavelength of red light of 600-700nm (that is, it does not have the same frequency and vibration direction in the physical

In everyone's daily life, many people will have various skin conditions. Shingles is a common skin condition in the body. When there are such symptoms, the body has a lot of unfavorable effects, such as skin itching, acne, etc. To deal with such conditions, everyone will immediately take certain effective measures to treat, then the red light treatment for shingles can be Is it effective? Let's introduce it below. Since shingles is a skin disease, the link where shingles can appear can be treated with red light. This link can be treated with red light, which can assist in anti-inflammatory and sterilization, and can also assist in anti-viral treatment, and you have shingles In the future, only red light treatment will not be sufficient. In this process, we should also take some medicines in cooperation with each other. We should also take care of our own skin and improve environmental sanitation, so that we can assist in the quick recovery. The prevalence rate of herpes zoster is still relatively high today. The cause of the disease is varicella-zoster virus infection. The virus infection that survives chickenpox in childhood is buried in the nerve roots. It will develop when the immunity is reduced. The larger feature is that the pain is spreading along the nerves, and the treatment is dominated by comprehensive treatment, including: 1. Anti-virus, improving immunity; 2. Nourishing nerves; 3. Symptomatic treatment and pain relief. Shingles has a certain degree of self-limitation. The general history of the disease is 3-4 weeks. It varies from person to person. Young people may have a shorter period of time, and older people may have a longer perio

There are many people with acne on the face. Facial acne can cause itching or pain. The common way to treat acne is to use red light therapy lamp. The actual effect of red light on acne is still very good, but when it is exposed to red light In the future, there will be many common problems. In addition to paying attention to skin cleansing, attention should be paid to the diet, otherwise it will affect the actual effect of the red light. The following actually introduces the common problems of the face after the red light therapy lamp. 1. Because the skin is relatively sensitive after red light treatment of acne, it is necessary to pay attention to sun protection and isolation, moisturizing and moisturizing within one or two days after treatment. When cleaning the skin, it should be as soft as possible, and the irritation should be used as little as possible. Pin etc. 2. After the red light treatment of acne, it is very important for patients to have sun protection and isolation. You should minimize exposure to the sun. If you need to go out to get the sun, you should pay attention to sun protection measures. 3. After the red light treatment of acne, the patient usually washes the care product level, and cleans the face softly to prevent the application of over-stimulating facial cleanser. Just rub it gently with a soft facial cleanser. 4. After the red light treatment of acne, the patient's skin is generally dry and irritable, so some water-soluble hydrating products can be used to carry out moderate hydrating and moisturizing. It is not suitable to have strong volatile, oil-soluble hydrating and moisturizing appliances. Do not use makeup or try to avoid makeup. Color makeup can seriously affect the treatment effect and may aggravate the condition of acne. If it is because of work reasons that you must make makeup, you should choose makeup pro

Women have always been confused by such and such gynecological inflammations and symptoms. If one's own resistance is reduced, it will cause pathogenic bacteria infection, and bear the confusion of symptoms such as itching, pain, and odor. After every cure, it will occur if you are not paying attention. No good treatment can be found. Methods, especially vaginitis, have been repeatedly tortured, and the spirit will collapse over time, and will continue to affect normal daily life. Recently, many women want to find a way to cure fungal vaginitis with a better actual effect. So what is the actual effect of red light treatment for fungal vaginitis? Can it be completely cured? Are there any stronger treatments? Authoritative experts emphasized that fungal vaginitis is a common disease with very large adverse effects for women. Once the body suffers, it will cause great damage and threats to the woman. If not treated immediately, it may aggravate the condition or transform into other gynecological inflammation, or even Can cause the possibility of female infertility. Many women have tried many methods to treat mycotic inflammation, including using their own lotion and buying medicines that can cure mycotic inflammation. If they are not cured, they continue to develop. Then the mycotic inflammation is really so difficult to treat. ? Some people strongly recommend red light treatment. There are many ways to remove the roots of fungal inflammation. The complete removal of rhizopus infestation generally requires a process. Therefore, vaginal cleaning is only an auxiliary treatment method, and it cannot be used as a key treatment method. For use, physical therapy methods include microwave therapy, red light therapy, etc. However, the actual effect of today's red light treatment is still very good

Acne, also known as acne, usually occurs during puberty. At this stage, medicine considers acne to be a skin gland disorder caused by multiple factors. Generally, red and blue light treatments are used. Red and blue light has the advantages of good effect, softness, and short treatment period. It does not affect work, study and training afterwards, and is a non-invasive treatment that does not damage skin tissue easily, has no side effects, and leaves after treatment. Sensitive skin is also OK Heal with peace of mind. Except for some special groups such as pregnant women, and those with autoimmune diseases such as lupus, albinism, those who are more sensitive to light, or those who have taken photosensitivity drugs, it is forbidden to use them, all of which can comfortably use red and blue light to carry out acne treatment . The basic principles of its actual treatment are as follows. Key rationale 1. Using the high-definition blue light effect on the epidermis, it can reasonably eliminate Propionibacterium acnes, inhibit bacteria, reduce inflammation, and quickly reduce swelling. 2. The red light effect in the deep tissues of the skin can reasonably stimulate the skin to regenerate collagen powder, promote the orderly development of fibroblasts, and immediately and reasonably improve the extensibility and fineness of the skin. This advantage is also Many anti-acne products cannot be compared. 3. Red and blue physiotherapy instrument, which uses helium-neon laser to have photoelectromagnetic, photochemical reactions and physiological effects on microbial tissues, dilate capillaries, improve the circulatory system and the whole process of metabolism, stimulate and adjust the physiological conditions of tissues, according to large-scale Direct injection can cause irritation to the meridians, adjust the body's yin and yang coordina

Vaginitis has caused some pain to female friends. Many female friends can`t perform normal daily life due to vaginitis. Vaginitis will cause vulvar itching, vaginal discharge and bad smell. Some patients have vaginitis doctors. It is recommended to choose red light treatment. Many patients are not clear about the red light treatment of vaginitis. What is the red light treatment of vaginitis? Let's take a look next. 1. What is the treatment of vaginitis red light? The red light treatment of vaginitis has a certain effect, but it needs to cooperate with each other. After direct red light, the specificity of catalase of membrane protein is improved, which can improve the basic metabolism of somatic cells, and then promote somatic newborns. Small fleshy tissues and hair growth and ulcers heal; in addition, it also promotes low-inflammatory mediators of white blood cells and enhances the body's immune function. The red light therapy device is a kind of phototherapy equipment based on the treatment principle of photochemical reaction. 2. What is vaginitis? Vaginitis, or Trichomonas vaginitis, is a group of symptoms that cause symptoms in the private vagina such as itching, burning, irritation and abnormal fluid discharge. The vagina of all normal physical and mental health women has a natural defense against pathogen invasion because of the characteristics of anatomical tissue. Such as the closure of the vagina, the front and back walls of the vagina are close together, the squamous epithelial cells in the vagina proliferate and surface somatic cell keratinization under the influence of estrogen, and the pH of the vagina remains stable, so that the breeding of pathogenic bacteria that incorporates alkalescence suffers Inhibition, while the cervical mucus is slightly alkaline.

Red light is a kind of light source that will be used in the whole process of acupuncture and moxibustion. After many experimental scientific researches, the application of red light to the body can indeed achieve certain therapeutic effects. The use of red light can reasonably promote the basal metabolism of the wound and improve the body's immunity. Some homes will buy red light therapy equipment professionally, and use red light to achieve certain health and health effects. So what is the benefit of using red light to directly irradiate the wound? What is the production of red light Visible light is the part of light that human eyes can recognize. The wavelength of light is in the middle of 350-770 nanometer technology. The scientific research on spectrometers has a history of more than 100 years. In 1666, Isaac Copernicus discovered from a prism that the white light of natural light is composed of light of various colors, namely red, orange, yellow, green, cyan, blue, and purple.

The physical characteristics of the production of red light Different lights have different characteristics. Acupuncture and moxibustion physiotherapy uses incoherent light with the key wavelength of red light of 600-700nm (th

Although the male body is stronger than the female body, it does not mean that all organs are stronger. In fact, some organs are weaker. Damage to these organs may affect the health of men and even affect their life span. Now let's take a look at the "four major organs". Liver Whether it is normal life or social interaction, the most inseparable thing is wine. Whether it is a yearning for life, or because of life pressure, work entertainment, the frequency of men's drinking and the amount of alcohol they drink, far exceed women. Excessive drinking often affects the liver. Although the liver is the body's hangover organ, its ability to withstand is also limited. Frequent excessive drinking will bring an irreversible burden to the liver. Men also need to pay attention to the health of their livers, go to the hospital for examinations when they are unwell, carefully follow the doctor's instructions, and try to reduce the amount and frequency of drinking, so that the liver can get an effective rest. Heart We often say that men have a strong heart, but in fact, the heart is also a major weakness of men. This is not only reflected in the physical, but also in the psychological. Physiologically, there are often smoking, alcohol abuse, or excessive obesity. These behaviors will cause a great burden on the heart.

Women are always plagued by gynecological inflammation and diseases. As long as their resistance to a decline, it will cause bacterial infection, suffering from itching, pain, odor and other diseases, every time after treatment, a do not pay attention will relapse, always can not find a good treatment, especially vaginitis, always repeatedly torture people, a long time, the spirit will collapse, will affect daily life. Recently, many girls want to find a better method to treat mycotic vaginitis. Can red light treat mycotic vaginitis? Is there any better treatment? Experts point out: mycotic vaginitis is a very harmful female common disease, once suffering from it, it will cause great harm and threat to women, and it is very important not to treat it in time May aggravate the disease or evolve into other gynecological inflammation, and even lead to the possibility of female infertility. Not a girl tried a lot of methods to treat fungal vaginitis, including their own lotion, buy the so-called can treat fungal vaginitis medicine, is not treated well, always relapse, so fungal vaginitis really so difficult to treat? Some people recommend red light treatment, mycotic vaginitis radical method is many, thorough Radical treatment of fungal vaginitis generally according to the steps, so vaginal irrigation is only an auxiliary treatment method, it can not be used as the main treatment method, physical therapy methods include microwave therapy, red light therapy, etc.

According to the red light is a common treatment method, has the glycogen content increased, the effect of this could increase the phagocytosis of white blood cells, thereby improving the body's immune ability, more extensive, the scope of its application in the treatment of burns, gynecology and internal medicine, surgery, such as the role of is right, according to the effect and side effect of red light? First, patients generally do not have side effects during red light treatment, but some uncomfortable symptoms may occur during the treatment of different diseases, such as small bumps on the skin or foreign body sensation in the eyes. Such reactions are only temporary and can gradually relieve and disappear spontaneously. Second: red light treatment can play a role in reducing swelling and pain and eliminating erosion, can completely eradicate the patient's pathological tissue in the body, in the treatment should be combined with the use of relevant drugs, in order to achieve a complete recovery as soon as possible, to prevent the disease will appear recurrence. Third, the therapeutic mechanism of the red light therapy instrument is to produce photochemical action on the organism, so that it produces important biological effects and therapeutic effects. Mitochondria absorb the most red light in cells, and the catalase activity of mitochondria increases after red light irradiation, which can increase the metabolism of cells.

At present, there are two commonly used methods in wound rehabilitation and disease physiotherapy, one is microwave therapy and the other is red light therapy. These two methods can speed up wound healing, but the working principle and scope of application are different, so we still need to distinguish. The working principle of microwave therapy is to generate electromagnetic waves of specific wavelengths through electromagnetic action. This ultra-high frequency electromagnetic waves are invisible and can penetrate human tissues and act on wounds through the "heat effect" to promote local blood circulation and accelerate cell recovery. Metabolism. The principle of red light's therapeutic effect is to irradiate the affected area with red light to promote wound healing. Red light refers to light with a wavelength between 630nm-670nm. This light is red and can be seen by the naked eye. Because light with a wavelength in this range can enhance cell energy, this light is widely used in clinical practice. . Red light can penetrate deep into human tissues, transfer energy to cells, accelerate cell repair, enhance cell phagocytosis, and achieve therapeutic effects. Both microwave therapy and red light therapy are very common clinical treatments. Microwave therapy is often used for the treatment of inflammation, tumors, traumatic bleeding, and internal trauma. Microwaves can produce thermal effects and promote the healing of human internal tissues through

As a global problem, hair loss is receiving more and more attention from the world, and the treatment of hair loss is changing with each passing day. Laser treatment takes a longer time to treat hair loss, and it is a relatively reliable treatment for hair loss. In 2007, the U.S. FDA approved a red light therapy (RLT) device with a wavelength of 660 nm for the treatment of AGA, and subsequently approved RLT devices with a wavelength of 678nm and 660nm for the treatment of androgenetic alopecia. , The red light in this wavelength range can penetrate the epidermis, exert a "photobiological regulation", and then improve the environment around the hair follicle, but its mechanism of action is not completely clear. Current research by some scholars suggests that RLT has a wide range of biological effects and is used to treat a variety of diseases, including promoting hair growth, wound healing and nerve regeneration. The mechanism by which RLT promotes hair growth may be related to improving microcirculation, reducing inflammation, increasing intracellular adenosine triphosphate (ATP), inducing the production of cytokines and growth factors, and directly stimulating keratinocyte stem cells or dermal papilla cells, which ultimately activates hair follicles in the resting phase Re-enter the growth period, prolong the growth period, accelerate the rate of hair growth and prevent the growth period from entering the resting period. The usage is generally to irradiate once every other day, irradiate for 15-30 minutes a day, and use it continuously for more than 3 months

Scientists in the UK are hopeful that new research into red light therapy could help humans to live healthier, longer lives. Professor Jeffrey at University College London initially studied the impact that red light has on the quality of life of fruit flies and was stunned by its impact. He told RAZOR: "The first thing we realized is that not only did we improve the metabolism of the flies but also the flies lived longer. They were much healthier in old age. "Research has also shown that they were healthier cognitively. They remembered things they wouldn't have done without the red light."

Basic knowledge of red light therapy: 1. 600-1200nm is the first treatment window of light on the skin 2. The absorption peak of hemoglobin is 415nm.540nm.580nm. So the penetration depth of 430nm ---1200nm light to the skin is basically proportional to the wavelength, 3. Short wavelength less than 480 has a tanning effect, 4. A peak absorption of vascular diseases at 540 and 580, 530 for superficial and small blood vessels, 560 for thick and large blood vessels. 5. The light absorption spectrum of melanin is that the absorption coefficient decreases monotonously as the wavelength increases. Also in order to avoid the side effects of <480nm, and considering that melanin is only distributed in the epidermis, shallow penetration is required. Therefore, while using the lower limit of 540nm to treat vascular lesions, it can also effectively remove black at the same time. If there is no vascular disease on the face, the lower limit is 590nm. At this time, it can not only remove wrinkles and rejuvenate skin, but also remove melanin, achieving the effect of "rejuvenation and whitening". 6. Wrinkle-removing skin rejuvenation is the target of photon is dermal tissue. On the one hand, a certain depth of penetration is required. The longer the wavelength in the visible to near infrared range, the deeper the penetration depth. On the other hand, the volume of dermal tissue is much larger than hemoglobin, capillaries and melanin, and of course the required calories are much larger. The longer the wavelength, the higher the photothermal conversion efficiency. Therefore, the lower limit of the wave band for wrinkle rejuvenation is selected near the lower limit of the
