Fractional laser technology is the newest and hottest technology in the United States in the last two years, and the most talked about technology in the global skin industry, and is a minimally invasive treatment between invasive and non-invasive. The theory of fractional laser treatment, called Fractional Photothermolysis, was first published in 2004 by Dr. Rox Anderson, an expert in laser medicine at Harvard University, and was immediately recognized by experts around the world and rapidly applied in clinical treatment.
Introduction
The fractional laser was originally developed and produced by the American Benevolent Group, and in 2008 it entered the Chinese market with an investment of 1.1 million US dollars to introduce the latest American service concept in Shanghai, China, and set up the first domestic BSP platform “beauty-speciaist Platforms” in Shanghai Yu Yan Beauty Equipment Co. “The concept emphasizes comprehensive skin solutions, that is, the same skin problem should be treated with a variety of instruments, which can reduce the adverse skin reactions and discomfort, so that the problem can be solved more thoroughly and less likely to recur.
Working Principle
The Fractional Photothermolysis theory is an extension of the traditional Selective Photothermolysis theory. It combines the advantages of both invasive treatment with fast and significant results, and non-invasive treatment with fewer side effects and shorter recovery time. Fractional laser treatment uses a laser to make microscopic holes in the skin evenly, which then causes a series of biochemical reactions in the skin to achieve skin tightening, skin rejuvenation and pigmentation removal. Since the fractional laser treatment only covers part of the skin tissue and the newly made holes do not overlap each other, some of the normal skin is preserved and recovery is accelerated. Patients can return to normal life after four to five days. The treatment itself is safe and can treat any part of the body, with indications including acne scars, discoloration reduction, surgical scars, traumatic scars, burn scars, melasma, Civatte skin heterochromia, wrinkles, skin laxity, and photoaging skin. These clinical applications are currently used both at home and abroad, and the efficacy is clear and certain.

Overview
Fractional laser is the newest and hottest skin care technology in the last two years, and the most talked about in the global skin industry. In Taiwan, it is known as Fractional Laser, and in the Mainland, it is called Fractional Laser. During this period, there is a “pixel laser” that imitates the fractional laser.
Fractional has the advantages of fast and significant results of invasive treatment, but also the advantages of non-invasive treatment with few side effects and short recovery time, combining the advantages of both.
The technology boasts the best of its kind in scar removal, especially for hyperplastic scars, acne scars and stretch marks. The use of fractional laser, a patented milestone technology, makes laser scar removal safer and more effective. Each treatment takes only tens of minutes and does not interfere with work and school life. Not only that, fractional laser also has excellent performance in acne, wrinkle and spot removal.
Classification
It can be mainly classified as
1550nm fractional laser
2940nm Erbium Glass Fractional Laser
10600nm ultra-pulsed CO2 fractional laser treatment principle
Fractional laser is just a mode of laser emission, fractional laser is installed with a special image generator (CPG), the image generator changes the light emission mode, fractional laser can emit 50μm-80μm focal spots through the high focus mirror, and these focal spots are scanned out up to 6 kinds of rectangular shapes (circle, square, rectangle, diamond, triangle, linear), which are suitable for different parts and Different skin types are treated.
The image generator (CPG) disperses the originally concentrated spot into tens to hundreds of smaller spots, i.e., tiny amounts of thermal damage are separated so that the normal tissues between the thermal damage are not affected and this part of the skin can be used as a thermal diffusion area to avoid possible side effects such as thermal damage and to promote the healing process of the skin. This way, the thermal damage to the skin can be reduced in a single treatment, and the effectiveness of the treatment can be ensured, and the pain of the patient can be reduced, so that the patient can return to daily life in a shorter period of time. Indications
Fractional laser can be effectively used for
1, acne and acne scars, scars and other treatment
2, removal of fine lines and dry lines around the eyes such as eyelids and crow’s feet
3, effective improvement of facial and forehead wrinkles, joint creases and stretch marks
4.Treatment of pigmented lesions such as freckles and cheekbone mother spots
5.Tightening and lifting of skin
6.Stretch marks and other deep scars
Unique advantages
1.Full wavelength power
Compared with traditional laser, fractional laser is more powerful and can directly reach the deep dermis of human facial skin to stimulate the repair of damaged part of the dermis, so that the dermis can produce more collagen and rearrange it to play the effect of skin rejuvenation.
2.Magic treatment without harm
Fractional laser uses a fractional laser system, using the ablative effect of the laser on the tissue, it can make micro-pores of 120-1200 microns in diameter on the skin, with a hole spacing of 500 microns, these micro-pores can be closed within a day after the treatment, which is difficult to see with the naked eye, and there is little oozing, bleeding and infection.
3.Personalized treatment plan can be customized
Fractional laser can be customized according to individual needs. The diameter and depth of the micropores can be adjusted during treatment. Among all lasers, only the fractional laser can achieve 5-100% adjustment of the treatment range and produce significant results in a single treatment.
4.National safety certification
Due to the strong penetrating power of fractional laser, it is less invasive and ensures uniform coverage of fractional micro-apertures to avoid overlapping of light spots. Therefore, it is the most suitable laser for comprehensive treatment, so that your skin can quickly restore a smooth image.
5.3-6 days, the skin can recover
During the treatment, small white dots in the form of a matrix are formed on the area directly penetrated by the laser. The skin around these dots immediately activates the horizontal repair mechanism and within 8 hours the epidermis is completely healed and can be washed and bathed. 3-6 days or so, the scabs at the dots fall off and the skin returns to its normal appearance. And the internal collagen regeneration can take up to 6 months, or even 6 years.
Technical breakthrough
1.Deep activation to remove scars, not only the surface work.
2.Two treatment heads, double surprise.
10MM treatment head: acts on deeper tissues for deep wrinkles, enlarged pores, acne and scars.
15MM treatment head: acting on shallower tissues, used for laser skin rejuvenation.
3.A wide range of action, doing enough surface work.
Difference Comparison
Pixel laser (beam laser) and fractional laser seem to have the same emission results, but in fact, pixel laser (beam laser) and fractional laser are completely different in terms of emission principles.
The pixel laser (beam laser) is a sieve-shaped image generator installed at the front of the emitter, which rigidly divides the laser beam into multiple tiny beams during laser emission, thus only spreading out the energy of the laser beam in terms of distance, but the heat still acts on the skin at the same time.
The fractional laser is a brand new laser beam, which is extremely small and fired very fast with a time difference, making it feel like the laser beam is fired onto the skin at the same time. It is more effective in reducing pain and side effects.
Because the fractional laser is so fast, it is also known in Taiwan as the “flying shuttle laser” to denote its fast emission speed, which has led to confusion with the pixel laser (beam laser).
Questions and Answers
Q: Why does the fractional laser not bleed during treatment?
A: The focal spot of the 1 fractional laser is as thin as a hair, with a diameter of only 50-80um producing a micro-hole of 50-120um in diameter on the skin. There is a small area of thermal coagulation around the micro-hole, and the temperature of this area is greater than 65 degrees Celsius, and this temperature can cause the blood to coagulate so there is no bleeding.
Q: What is the difference between 1 fractional laser and microneedle?
A: Microneedling is the application of rolling needles to produce microscopic holes in the skin to directly damage the tissue structure of the skin to occur the inflammatory repair response, the diameter of the microscopic holes is large and there is no thermal effect i.e. thermal coagulation and thermal effect so no collagen contraction and renewal will be produced.
Q: 1 fractional laser is more effective for which facial wrinkles
A: 1 Fractional Laser is more suitable for mild to moderate wrinkles, especially fine wrinkles that cannot be eliminated by surgical procedures and soft tissue fillers.
Q: Why does the 1 fractional laser penetrate to a depth of 2mm and not deeper
A: Because UV light exposure causes degeneration of elastic fibers at a depth of 2mm, so 1 Fractional Laser is set to control the depth at 2mm thus changing the skin problems caused by photoaging.
Q: Is the effect obvious at that time or later after 1 Fractional Laser?
A: The lifting effect will be obvious at that time, mainly caused by the collagen contraction due to the thermal effect, but there will be collagen renewal in the later stage. So you will find that the skin will become better and better in the later stage, the texture will become more and more delicate, and the wrinkles will become lighter and lighter.
Q: What will be the changes after a course of 1 fractional laser for normal people?
A: The facial contour will be obviously sculpted, the face will be lifted and become tight, the skin will become smooth, delicate, shiny and elastic, fine wrinkles will disappear, and deep wrinkles will become significantly shorter and lighter.
Q: Will the skin be sensitive and thin after the procedure?
A: 1 Fractional laser works on the skin by scanning in a disorderly way, the focal spot diameter is only 50-80um and the damage to the epidermis is very small, and the treatment will make the collagen fibers new and thicken the dermis, so it will only improve the skin and not thin it.
Treatment of scars
Fractional laser is divided into nearly 100 micro laser pulses, each micro laser spot is only 75-100um, when these tiny laser beams act on the surface of the skin, it will stimulate the growth of collagen and elastic fibers in the subcutaneous dermal tissue. It lightens the scars and eliminates acne marks, thus achieving the effect of removing acne marks.
The fractional laser can act only on tiny parts of the skin, using the normal skin tissue around the small spot to accelerate the healing rate of the treated area. The result is to achieve the treatment purpose while avoiding side effects such as postoperative pigmentation of erbium laser or CO2 laser grinding, making it a good method that can effectively treat acne scars and marks with high intelligence, adaptability and safety.
Wrinkle Removal Operation
A. Before the fractional laser wrinkle treatment, the machine needs to be preheated for 20 minutes, at which time the beautician will make the necessary skin care for you and clean up the facial skin.
Before the fractional laser wrinkle treatment starts, you will put on the protective eye mask and the physician will adjust the treatment parameters and laser energy according to your skin condition, then the laser light will be irradiated to the wrinkled skin.
Three, fractional laser wrinkle treatment does not require anesthesia, no need to apply cooling gel, no pain. The treatment process takes about twenty minutes and is very easy.
Fourth, fractional laser wrinkle removal should be actively cooperated with the doctor’s requirements, no need to fear anesthesia to choose according to their tolerance to discuss with the doctor. To establish confidence. After laser wrinkle removal, you should carefully implement the medical advice and treatment, and do as required to prevent complications, even if complications arise, do not panic, and actively cooperate with the doctor to deal with them in a timely manner, and strive for early recovery after surgery.
Advantages of wrinkle reduction
