According to clinical statistics, the most popular treatment in medical beauty clinics is phototherapy, because phototherapy not only causes little damage to the skin, but also can recover quickly, making many beauty lovers eager to try it.

Mild light waves secretly turn beautiful
Light therapy in a broad sense includes various types of single-wavelength lightning Radiation, and composite wavelength pulsed light, use different wavelengths of light and energy to produce different therapeutic effects on the skin.
Yijun, an office worker, is always praised for her beauty recently! But it seemed that there were no major changes. Handkerchief Meiling finally couldn't help but ask her secretly today, and Yijun revealed that she took advantage of these two weekends and holidays to undergo a "face-changing surgery." In fact, it was phototherapy plus micro plastic surgery to remove the spots on her face that had to be covered up with concealer. She also used Botox to make the baby fat on her cheeks disappear. Her face seemed to look smaller instantly. Number.
After solving the mystery, Handkerchief Meiling is also eager to follow the "invest in yourself", but when entering the many beauty markets in the market, she feels like a "lamb to be slaughtered", and the types of information are so complicated. There are many types of laser phototherapy equipment. In the information, laser, phototherapy, radio wave facelift, powder laser, pulse light, shuttle laser... the various terms are confusing to people just looking at them, let alone trying to figure out what they should do. Where to start? Fortunately, her sister Tao Yijun took her to a professional medical institution to seek help from doctors at the medical beauty center. She first clarified her skin type, and then assessed the improvement goals and prescribed the right medicine, so that Mei Ling could also "secretly transform" Beautiful dream!
According to clinical statistics, the most popular treatment in medical aesthetic clinics is phototherapy! Wang Guoxian, an attending physician at the Department of Dermatology, Taipei Medical University Affiliated Hospital, said that the summer vacation season has arrived recently. In the past, people may have the impression that only ladies or socialites would go to the medical aesthetic clinic, but now medical aesthetics has become "closer" to a considerable extent. "In public life, even office workers may take advantage of their lunch break to have a "micro-plastic surgery" or "phototherapy afternoon tea" for themselves. Summer vacation is here, and students are beginning to join the beauty-loving ranks. Outpatient clinic numbers speak for themselves. The closer we get to the summer vacation, the more people make appointments for medical treatment. Among them, "light therapy", which is not invasive to the skin and can recover quickly, is the most popular. Popular with the public.
Remove traces of aging
The so-called light therapy in a broad sense includes various types of lasers with single wavelengths and pulsed light with composite wavelengths, which use different wavelengths of light and energy to produce different effects on the skin. therapeutic effect. Wang Guoxian said that ultraviolet rays in the sun will cause photoaging of the skin. However, if light of specific wavelengths and energy is properly utilized, it can improve the traces left in the aging process and promote the regeneration of skin collagen.
Wang Guoxian further explained that the well-known laser in phototherapy can emit energy in a very short period of time. The output is light of a single wavelength. Its light wave width is very narrow and it emits in a point shape. Therefore, , can cause selective damage. Therefore, the scope of treatment is quite wide. At present, the field of medical aesthetics has been applied in hair removal, spot removal, microdermabrasion, birthmark removal technology, etc., and has become quite proficient.
People can choose to have injections after discussing with doctors. However, the cost will depend on factors such as the precision of the instrument or the skill of the doctor. Therefore, the price in the market is confusing. For mole spotting, it is about 2,000 to 2,000 to The price is around 3,000 yuan, and the fee for spot removal and microdermabrasion is around 10,000 yuan, but the quality of the work cannot be controlled. Doctors can only recommend that people consult regular medical institutions first, have a basic understanding of the current condition of their skin, understand what should be done and what should not be done, and ask about the price before arranging medical aesthetic treatments to avoid being taken advantage of later. .
Pulsed light has become the new mainstream
Wang Guoxian said that unless it is a minor operation such as superficial spots and small granulations, laser beauty can usually not be completed in one go. Most of the time, more than 2 to 5 treatments are required. Most laser surgeries require several treatments, including days of rest, in order to gradually improve the lesions.
Moreover, it takes about 2 weeks for the wound to scab after laser surgery, and a recovery period must be allowed for recovery afterwards. If the laser treatment area is large and the depth of the treatment is deep, similar to major surgery, the recovery period may be longer. For up to six months, you need to stay clean and pay attention to sun protection during this period. These must be included in the pre-operative assessment.
Because traditional laser treatment can only treat one type of skin problem with one wavelength, the skin will feel painful during the treatment, so anesthesia must be applied. There will be wounds on the face after the operation, and there must be a period of time. The recovery period is relatively long, so more and more people do not want to be beaten up again, so they choose the more "narrow" phototherapy for beauty, which is called the new development of phototherapy──"pulse" Light".
There are not many contraindications to its use
According to data from the Medical Laser Optoelectronics Society, the current application of pulsed light in medical cosmetology mainly has five major functions, namely the removal of sun spots. , freckles, epidermal dark spots, remove telangiectasia, facial flushing, tighten the skin, remove fine lines on the skin and reduce pores, etc.
Generally speaking, there are not many contraindications to use, but patients with dermatitis or facial herpes simplex can wait until they are well treated before undergoing pulsed light therapy. Due to the short operation time of pulsed light, the principle is like a packaged product, including light waves from short to long. Therefore, it can not only act on the surface of the skin at the same time, but also penetrate deep into the connective tissue and capillaries under the skin.
In terms of the operating principle, composite wavelength pulsed light uses an appropriate arc lamp to output light containing various wavelengths in a high pulse manner, and is then filtered by different chips to make the pulsed light There are higher energies in different wavelength segments. Wang Guoxian said that pulsed light is a multi-wavelength, high-energy pulsed flash that operates on a very wide spectrum, about 550 to 1200 micron wavelength light.
The treatment goals of various light waves are different
Lu Peixuan, an attending physician at the Medical Cosmetology Center of Chang Gung Memorial Hospital, also said that pulsed light can output a variety of high-energy and wavelength light, but not all The light waves are released all at once, but you need to select the wavelength of light you want to use. Each pulse band has a special corresponding treatment target. For example, pulsed light can be used to treat red inflammatory acne, facial vasodilation, rosacea dermatitis, skin photoaging, sun spots, freckles, hemangiomas, hair removal, etc., just because the skin tissues to be targeted are different, such as Melanin, blood vessels, and melanin around hair follicles will also have different wavelengths, pulse widths, and pulse intervals.
Pulse light includes visible light and infrared range, covering almost all commonly used laser wavelengths: (dye laser 595nm, ruby ??laser 694nm, alexandrite laser 755nm, diode laser 900nm, rubidium Jacques Laser 1064nm, etc.), therefore, pulsed light is a combination of various lasers, and the operation must be based on the clinical judgment of a professional physician. From the composite light wave of pulsed light, the appropriate wavelength range and irradiation time can be selected according to the skin problem. There can be countless combinations of treatment parameters. It depends entirely on the doctor's experience and judgment to avoid damage to nearby tissues. Therefore, The importance of doctors and their level of experience and skills are also shown here.
Pulsed light treatment band
At present, the pulsed light treatment band can be divided into four major modes:
◎Vascular mode VL: vascular light 515, 550, 570, 590 nm
◎Pigment mode PL: Pigment light 515, 550, 570, 590, 615, 645 nm
◎Hair removal mode HR: Hair removal light 695, 755nm < /p>
◎Phototherapy Rejuvenation SR: Cosmetic light 560, 640 nm
Don’t skimp on post-operative care
Currently, phototherapy has become a very popular medical aesthetic treatment. Before planning to receive treatment and after surgery, you should do a good job of home care so that your skin can be maintained in the best health condition.
Many people think that lasers have various names and are not aware of the differences. In fact, it is usually caused by different types of instruments used by manufacturers or operators. Wang Guoxian, an attending physician at the Department of Dermatology, Taipei Medical University Hospital, said that everyone knows that visible light is composed of red, orange, yellow, green, blue, indigo, violet and other colors of light. It releases light waves according to specific wavelengths. It can be visible light according to the wavelength. Including red, yellow, blue, green, and purple light, therefore, there are terms such as red light laser, yellow light laser, and ultraviolet laser. In addition, there are products such as ruby ??laser, alexandrite laser, Alexander laser, garnet laser, diode laser, etc., which are named after the type of medium in the middle.
In the actual operation of pulsed light therapy, it can be carried out directly without applying ***. The doctor will first apply a layer of iced induction gel on the skin, which can not only protect the surface skin from The pulsed light is thermally damaged, and the light is effectively transmitted to the inner layer of the skin. During the treatment, the skin will feel a bit like it has been quickly burned by fire, but it will not sting.
Treatment will be done after a doctor’s assessment
After treatment, the face will be slightly red and swollen, and scabs will appear in areas with superficial spots within 3 to 7 days. You will feel it when you wash your face. The skin will feel dry and rough to the touch, and the scabs will fall off on their own, and the patient can return to his normal life. Since scabs or wounds are unlikely to occur, he only needs to strengthen sun protection and moisturizing after the operation. Generally, there will be no special care. trouble. Lu Peixuan, the attending physician at the Medical Aesthetics Center of Chang Gung Memorial Hospital, reminds the public that the number of pulsed light treatments required depends on the skin problem you want to solve. If it is used for phototherapy to rejuvenate, it is recommended to do it once a month. After three treatments, depending on the skin condition, three Perform regular maintenance once a month.
Doctors said that in the professional field of dermatology, pulsed light is still tended to be regarded as a "non-main treatment method". The low-priced pulsed light treatment available in the market may not have enough treatment sessions, or may require consumers to A package of treatments is required, and the single charge for pulsed light is NT$6,000~8,000, which is a reasonable fee.
However, pulsed light is not a panacea. Doctors advise that in terms of "skin rejuvenation", although pulsed light can make the skin firmer and more elastic and remove fine lines, it is still unable to treat severely sagging skin. Achieve the results of traditional facelift surgery. As for the treatment of pigmented spots, it is also more effective for spots in the epidermis. If it is deep pigmentation, it still needs to be evaluated by a dermatologist. After making a correct diagnosis, the most suitable treatment method can be selected.
Moisturizing and sun protection are required before and after surgery
Another phototherapy technology that is often confused with pulsed light in clinical practice is "light emitting diodes". LEDs), Lu Peixuan explained that pulse light is not differentiated into red, yellow, blue, and green light. Those that are differentiated into red, yellow, blue, and green light are light-emitting diodes.
This is a semiconductor electronic component that can emit light. This electronic component appeared as early as 1962. In the early days, it could only emit low-luminosity red light. Later, other monochromatic light versions were developed. Today, the light that can be emitted has covered visible light, infrared and ultraviolet rays, and the luminosity has also increased to a considerable luminosity.
Phototherapy is already a very popular medical aesthetic treatment. Before planning to receive treatment, you should take care of your skin at home to maintain the best health of your skin and strengthen moisturizing and sun protection. People with sensitive skin or those whose skin is prone to redness and sensitivity should be more calming and soothing.
After the operation, although the treatment is not that destructive to the skin and the postoperative recovery period is also very short, the epidermal layer of the skin after the operation is in the stage of micro-regeneration and is relatively fragile and dry, so it needs to be strengthened. Moisturizing and sunscreen, on the one hand, give the skin enough moisture, and on the other hand, try to block ultraviolet rays from killing melanin hyperplasia again, so that the entire treatment will not be wasted.
Choose natural skin care products
Choose carefully when it comes to skin care products. Try to choose mild moisturizing products to enhance moisturizing. The first week after surgery is especially important. Lu Peixuan emphasizes that "natural is best". Avoid using non-toxic facial cleansers at this stage. Routine exfoliation must also be suspended, and skin care products that can easily clog the skin should also be stopped.
To avoid unnecessary irritation, for the original moisturizing and maintenance action, you can first apply the product locally to see if it will cause irritation in the skin, and then gradually use it on the entire face.
As for sun protection and moisturizing, the concepts are the same as usual. To avoid excessive sun exposure, you can use a sun hat or parasol to avoid direct exposure to the sun. However, after surgery, you often stay indoors in an air-conditioned environment. When the air conditioner is fully turned on, it will reduce the humidity in the air. You can place a wet towel indoors to increase the moisture content of the air and help keep the skin moist.
After external moisturizing is done, internal moisture is also indispensable. In terms of diet, drink more water, stay up less late, eat as light a meal as possible, and reduce staying up late or eating alcoholic foods, such as pungent, greasy, and coffee. , wine, etc.
In addition, you can take in more vitamin C, because vitamin C is a natural antioxidant, such as onions, garlic, broccoli and citrus, etc., which are rich in vitamin C
