Mild light waves secretly become beautiful.
Phototherapy in a broad sense includes all kinds of laser with single wavelength and pulsed light with composite wavelength, and uses different wavelengths of light and energy to produce different therapeutic effects on the skin.
Yijun, an office worker, has always been praised for being beautiful recently! However, I can't seem to say where there have been major changes. Handkerchief Meiling finally couldn't help secretly asking her today. Yijun revealed that she had "face-changing surgery" during these two weekends and holidays. In fact, it is phototherapy plus micro-shaping, removing spots that must be concealed, and using botulinum toxin to make the baby fat on both cheeks disappear. Her face seems to have shrunk by one size in an instant.
After solving the mystery, Pajiao Meiling also eagerly followed "investing in herself", but when she entered many beauty markets, she felt like a "lamb to be slaughtered". The types of materials are complex, and there are many kinds of laser phototherapy equipment. In terms of materials, laser, phototherapy, electric wave lift, powder cake laser, pulsed light, shuttle laser and so on. All kinds of terms are confusing, not to mention trying to figure out what to do. Fortunately, my sister Tao Yijun took her to a professional medical hospital and asked a doctor in a medical beauty center for help. First, she made clear her skin type, and then she assessed that she should improve her goal and prescribe the right medicine to make Meiling realize her dream of "secretly becoming beautiful"!
According to clinical statistics, the most rigorous course of treatment in medical beauty clinics belongs to phototherapy! Wang, an attending physician in dermatology at the Affiliated Hospital of Taipei Medical College, said that it was the summer vacation season recently. In the past, people may think that only ladies or celebrities will enter the medical beauty clinic, but now medical beauty has been "close" to public life to a considerable extent, and even office workers may use their lunch break to do a "micro-plastic surgery" or "phototherapy afternoon tea" for themselves. As the summer vacation approaches, students begin to join the ranks of beauty lovers. The number of outpatients can talk. The closer the summer vacation is, the more people will make an appointment. Among them, the "phototherapy course" which is non-invasive and can be quickly recovered is the most popular among the people.
Remove the traces of aging
The so-called phototherapy in a broad sense includes all kinds of single-wavelength laser and pulse light with complex wavelength, which use different wavelengths of light and energy to produce different therapeutic effects on the skin. Wang said that ultraviolet rays in sunlight can cause photoaging of skin, but if light with specific wavelength and energy is used well, it can improve the traces left in the aging process and promote the regeneration of skin collagen.
Wang further explained that the well-known laser in phototherapy can emit energy in a very short time, and the output is light with a single wavelength, and its light wave width is very narrow, and it emits in points, so it can cause selective damage. So the scope of treatment is still quite wide. At present, the field of medical beauty has been applied to depilation, freckle removal, dermabrasion, birthmark removal and so on, and it has been quite proficient.
People can choose to use the drug after discussion with doctors, but the cost will be affected by factors such as the fineness of the instrument or the skills of doctors. Therefore, the price in the market is rather chaotic, ranging from 2,000 to 3,000 yuan in Dot mole, and the cost of removing spots and peeling is about10,000 yuan, but the quality of smearing can't be mastered. Doctors can only suggest that you go to a regular medical institution for consultation first, have a basic understanding of your skin condition, know what to do and what not to do, and ask the price clearly before arranging medical beauty courses to avoid being cheated afterwards.
Pulsed light becomes the new mainstream.
Wang said that unless it is a minor operation such as superficial spots and small granulation, laser beauty is generally not completed at one time, and most of them have to be treated for more than two to five courses. Most laser operations need to be treated several times, including the interval of days, in order to gradually improve the lesions. Moreover, it takes about 2 weeks for the wound to scab after laser surgery, and then a recovery period must be reserved. If the laser treatment area is large and the depth is deep, the recovery period may be as long as half a year. During this period, it is necessary to keep clean and pay attention to sun protection, which must be included in the preoperative evaluation.
Just because the traditional laser treatment can only deal with one kind of skin problem, the skin will feel pain when it is applied, so it is necessary to play anesthetic, and there will be wounds on the face after operation, and there must be a long recovery period. Therefore, more and more people will choose narrower phototherapy because they don't want to be labeled as "bean curd residue", which is called the new progress of phototherapy-"pulsed light".
There are not many taboos in use.
According to the data of Medical Laser Optoelectronic Society, at present, the application of pulsed light in medical cosmetology mainly has five functions, namely, removing sunburn, freckles and epidermal dark spots, removing telangiectasia, facial flushing, firming skin, removing fine lines and reducing pores.
Generally speaking, there are not many contraindications in use, but patients with dermatitis or facial herpes simplex can wait for treatment before pulse light therapy. Due to the short running time of pulsed light, the principle is like a wrapped product, which contains light waves from short to long. Therefore, it can not only act on superficial skin at the same time, but also penetrate deep into subcutaneous connective tissue and microvessels.
As far as the working principle is concerned, the multi-wavelength pulsed light uses a suitable arc tube to output light with various wavelengths in a high pulse mode, and then it is filtered by different wafers, so that the pulsed light has higher energy in different wavelength regions. Wang said that pulsed light is a multi-wavelength, high-energy pulsed flash with a wide spectrum and a wavelength of about 550~ 1200 micron.
All kinds of light waves treat different people.
Lu also said that pulsed light can output all kinds of high-energy and high-wavelength light, but instead of releasing all the light waves at once, you should choose the wavelength light you want to use, and each pulse band has a special treatment target. For example, pulsed light can be used to treat red inflammatory acne, facial vasodilation, vinasse dermatitis, skin photoaging, sunburn, freckles, hemangioma, hair removal and so on. Just because the skin tissues to be targeted are different, such as melanin, blood vessels, melanin around hair follicles, wavelength, pulse width and pulse interval are different.
Pulsed light includes visible light and infrared light, covering almost all wavelengths of commonly used lasers: (dye laser 595nm, ruby laser 694nm, emerald laser 755nm, diode laser 900nm, rubicon laser 1064nm, etc. Therefore, pulsed light is a combination of various lasers, and surgery must be judged by a professional doctor. From the composite light wave of pulsed light, we can choose the appropriate wavelength range and irradiation time for skin problems. There can be countless combinations of treatment parameters, and relying entirely on the experience and judgment of doctors will not cause damage to nearby tissues. Therefore, the importance and experience and technical level of doctors are also shown here.
Pulsed light therapy band
At present, the therapeutic band of pulsed light can be divided into four modes:
◎ Vascular pattern VL: vascular light 515,550,570,590 nm.
◎ Pigment pattern PL: Pigment light 515,550,570,590,61645 nm.
◎ hair removal mode HR: hair removal light 695 and 755nm.
◎ Phototherapy skin rejuvenation SR: beauty light 560 and 640 nm.
Do not cut corners after operation and maintenance.
At present, phototherapy has become a very popular medical beauty course. From before the planned treatment to after the operation, family care should be done to keep the skin in the best health.
Many people will think that the names of lasers are varied and they don't know the difference at all. In fact, it is generally caused by different manufacturers or manufacturers and different types of instruments. We all know that visible light is composed of red, orange, yellow, green, blue, indigo and purple. Depending on the specific wavelength, light waves can be visible light, which usually includes red, yellow, blue, green and purple light. So there will be red laser, yellow laser and ultraviolet laser. In addition, there are ruby laser, emerald laser, garnet laser, diode laser and other products, named after the medium in the middle.
In the actual operation of pulsed light therapy, it can be carried out directly without painting. The doctor will first apply a layer of iced induction gel to the skin, which can not only protect the surface skin from the thermal damage of pulsed light, but also effectively transmit the light to the inner skin. During the treatment, the skin will feel a little burnt, but it will not sting.
Doctor's evaluation before treatment.
After treatment, there will be slight redness and superficial spots on the face, and scab skin will appear within 3 ~ 7 days. When washing your face, the skin on your face will feel dry and rough, and the scabbed skin will fall off on its own, and the patient can return to normal life. Because scabs or wounds are unlikely to occur, it is good to strengthen sunscreen and moisturizing after surgery, and there will be no special trouble in usual care. Lu, an attending physician at the Medical Beauty Center of Chang Gung Memorial Hospital, reminded the public that the number of times pulsed light needs treatment depends on the skin problems to be solved. If it is used for phototherapy and rejuvenation, it is recommended to do it once a month. After three treatments, it can be maintained regularly every three months according to the skin condition.
Doctors said that in the field of dermatology, pulsed light is still regarded as "non-main treatment". Low-cost pulsed light therapy on the market may not be enough, and consumers still need to cover the course of treatment. The single charge of pulsed light is NT$ 6000-8000, which is reasonable.
However, pulsed light is not everything. The doctor warned that although pulsed light can make the skin firmer and more elastic and remove fine lines, it still can't achieve the effect of traditional face lift surgery for severely flabby skin. In the treatment of pigmented spots, it is also effective for spots on the epidermis. If it is deep pigmentation, it still needs to be evaluated by a dermatologist, and then the most appropriate treatment method is selected after making a correct diagnosis.
Moisturizing and sun protection are needed before and after operation.
Another phototherapy technique that is often confused with pulsed light in clinic is "light emitting diode" (led). Lu explained that pulsed light can not distinguish dividends, yellow, blue and green light, but light-emitting diodes.
This is a semiconductor electronic component that can emit light. This electronic component appeared as early as 1962. Only low luminosity red light can be emitted in the early stage. Later, other versions of monochromatic light were developed. Today, the light that can be emitted has spread all over visible light, infrared light and ultraviolet light, and the luminosity has also been improved to a considerable extent.
Phototherapy has always been a very popular medical beauty course. Before planning treatment, we should do a good job in maintaining the skin at home, keep the skin in the best health, and strengthen moisturizing and sun protection. People with sensitive skin or sensitive skin should be calm and soothing.
After the operation, although the course of treatment is not so damaging to the skin, and the postoperative recovery period is also very short, the postoperative epidermal skin is in the stage of minimally invasive newborn, fragile and dry. It is necessary to strengthen moisturizing and sun protection, on the one hand, give enough moisture to the skin, on the other hand, try to prevent ultraviolet rays from proliferating melanin again, and don't let the whole course of treatment be wasted.
Choose natural maintenance products.
Care products should be carefully selected, try to choose mild moisturizing products and strengthen moisturizing, which is more important within one week after operation. Lu Pei Xuan emphasized that "human nature is good". At this stage, avoid using facial cleanser, stop routine exfoliation and stop using skin care products that are easy to block the skin. Avoid unnecessary * * *, the original moisturizing and maintenance action, you can first apply the product to the local area, try to see if it will produce * * * sensitivity, and then gradually use it on the whole face.
As for the concept of sunscreen and moisturizing, it is no different from the usual practice. In order to avoid excessive sun exposure, you can use a sun hat or sunshade to avoid direct sunlight. But I often stay indoors in an air-conditioned environment after operation. When the air conditioner is fully open, it will reduce the humidity in the air. You can put a wet towel indoors to increase the water content of the air and help keep your skin moist.
The external moisturizing is done, and the internal moisture is indispensable. In terms of diet, drink more water, stay up late less, eat as lightly as possible, and reduce staying up late or eating, such as bitterness, greasy, coffee, wine, etc.
In addition, you can take more vitamin C, because vitamin C is a natural antioxidant, such as onions, garlic, cauliflower, citrus and so on are rich in vitamin C.
