Treatment of freckles with Photofacial M22 with little downtime

Photofacial M22 is a medical device that has been approved by the Ministry of Health, Labor and Welfare for its safety and efficacy, and is an IPL (light) treatment machine that can be expected to improve various skin problems. It is said to be effective in improving freckles, and some treatments can be expected to have a synergistic effect when taken with Photofacial M22.

There are treatment methods other than Photofacial M22 for improving freckles, so by knowing the difference in the progress after receiving the treatment, downtime symptoms, fees, etc., you can improve freckles with the optimal treatment method that suits you. You can aim.

Definition of freckles

Freckles are fine spots that form from the nose to the cheeks, and are also called freckles because they resemble the color of sparrow eggs.

Freckles are often inherited and develop in childhood and tend to increase and thicken during puberty . It is generally said that freckles tend to decrease or become thinner after puberty, but changes such as freckles decreasing or becoming thinner vary greatly from person to person, and the amount and thickness of freckles varies from person to person.

Mechanism for freckles

Mechanism for freckles Freckles are caused by the excessive accumulation of melanin in the epidermis .

Melanin is produced to protect the skin from stimuli such as ultraviolet rays, but when the amount of melanin increases, it is normally excreted from the body by turnover, which is the metabolism of the skin, so it looks like freckles. Will not be.

However, for those who have freckles, melanin is likely to be excessively produced by stimuli such as ultraviolet rays, and the excessively produced melanin is accumulated in the epidermis. If the amount of melanin increases too much, it will exceed the amount that can be excreted by turnover, and melanin will accumulate and become visible as freckles .

Spots can be created by the same mechanism, but unlike freckles, they develop with age, so they become more noticeable after the 30s. It is also larger than freckles and has the difference that it is more likely to form in front of your ears or on your temples.

Photofacial M22 mechanism for freckles

Photofacial M22 is a machine that uses the energy of light called IPL (Intense Pulsed Light) to damage skin problems such as melanin and hemoglobin and improve skin problems such as spots, freckles, and acne scars .

Can irradiate with wavelengths that thin freckles

Light has a wave-like property, and the length from the peak to the peak (valley to valley) of the wave is called the wavelength. There are names such as ultraviolet rays, visible rays, and infrared rays depending on the wavelength, and they are expressed in units of nanometers (nm), which is one billionth of a meter.

Melanin and hemoglobin, which are the causative substances of skin problems, have the property of absorbing the wavelength of light. When the causative substance absorbs light, heat energy is generated, and the generated heat energy damages the causative substance and is discharged to the outside of the body, leading to improvement of skin problems.

Like IPL, lasers that can damage the causative substances of skin troubles with the energy of light have only a single wavelength such as 694 nm and 1064 nm, but the IPL treatment machine Photofacial M22 has visible light and infrared rays. It has a wide range of wavelengths from 515 nm to 1200 nm, which corresponds to this.

wavelength

Photofacial M22 has nine types of filters that cut unnecessary wavelengths so that wavelengths are easily absorbed by substances that cause skin problems such as melanin and hemoglobin.

When performing treatment on freckles, select a filter with a wavelength that is easily absorbed by the causative substance, melanin. Also, depending on whether the melanin is in the shallow or deep part of the skin, the filter is selected and the treatment is performed.

Dedicated filter Corresponding symptom freckles
515nm Spots near the surface of the skin
560nm Spots, pores, wrinkles, acne, etc. near the surface of the skin
590nm Red face (telangiectasia), acne scars, etc.
615nm Stain that could not be removed at 515 nm or 560 nm
640nm Stain that could not be removed at 515 nm or 560 nm
695nm Blemishes and hair loss in deep skin
755nm Blemishes and hair loss in deep skin
Vascular (filter for blood vessels)
530-650nm, 900-1200nm
Specializing in vascular lesions such as red face, telangiectasia, and internal bleeding
Acne (acne filter)
400-600nm, 800-1200nm
Specializing in acne treatment that suppresses inflammation and kills P. acnes

Effect on skin problems other than freckles that can be expected by having multiple wavelengths

Since Photofacial M22 has multiple wavelengths, it can be expected to be effective for skin problems other than freckles, such as spots, pores, wrinkles, acne, and reddish face .

After irradiating the entire face with a filter that can be expected to be effective for freckles, replace it with a filter suitable for other problems and irradiate again, so that you can treat multiple skin problems with one treatment without changing the machine. An approach is possible.

Irradiation time and output related to the heat energy given to freckles

The irradiation time and output of Photofacial M22 are related to increasing or decreasing the heat energy given to melanin, which is the causative agent of freckles.

Irradiation time called pulse width

The time required to irradiate one light wavelength such as IPL is called the pulse width, and is expressed in units such as milliseconds, microseconds, nanoseconds, and picoseconds.

Picoseconds (ps) 1 / 1,000,000,000,000s (1/1 trillion seconds)
Nanoseconds (ns) 1 / 1,000,000,000s (1 billionth of a second)
Microseconds (μs) 1 / 1,000,000s (1 / 1,000,000 second)
Milliseconds (ms) 1 / 1,000s: Long pulse

About pulse width

The pulse width that can be set differs depending on the IPL machine, but the shorter the pulse width , the stronger the instantaneous thermal energy generated after melanin absorbs the wavelength of light . The pulse width that can be set with Photofacial M22 is 4 ms to 20 ms.

The higher the output of the IPL to be irradiated, the stronger the effect on freckles.

The strength of the heat energy acting on melanin changes depending on how much output the IPL is applied to melanin, which is the causative agent of freckles. The output of IPL is the density of energy of IPL irradiated per square centimeter, and is expressed in the unit of J (joule) / ㎠.

On IPL treatment machines other than Photofacial M22, increasing the output increases the pulse width per shot and reduces the instantaneous thermal energy (peak power) generated after melanin absorbs the wavelength of light.

On the other hand, in the case of Photofacial M22, it is said that the pulse width does not become long even if the output is increased, and the peak power can be maintained, so the action on melanin is not weakened. The output that can be set with Photofacial M22 is 10 J / cm2 to 35 J / cm2.

However, if the output is increased too much, the heat energy is too strong and there is a risk of inflammation and pigmentation after inflammation , so to improve freckles, it is necessary to damage melanin with an appropriate wavelength, pulse width, and output. There is.

It is possible to thin a wide range of freckles

Since freckles are spread over a wide area and there are many, it takes time to irradiate each one, but with Photofacial M22, you can irradiate a wide area at once. The entire face treatment takes as little as 10 to 15 minutes .

The Photo Facial M22 has three types of light guides that come into direct contact with the skin, allowing you to change the range of irradiation. Use a 15 mm x 35 mm square type for wide areas such as the forehead and cheeks, an 8 mm x 15 mm square type for small areas such as the eyes and mouth, and a 6 mm diameter round shape for narrow areas. To prevent.

Effective treatment when used in combination with Photofacial M22

  • Chemical peeling
  • Iontophoresis
  • laser
  • Internal / external medicine

Chemical peeling that promotes turnover

Chemical peels, which peel off the skin by applying the drug directly to the skin, can promote turnover, which is the metabolism of the skin.

The overproduced melanin is pushed up to the stratum corneum by turnover and excreted from the body. However, there is no immediate visible change and it gradually fades, so trying to treat freckles with chemical peels alone tends to take months to years.

However, in the photofacial M22 treatment, after damaging melanin, it appears in the stratum corneum as a microcrust within 1 to 2 days. It takes about 3 days to 1 week to remove all the microcrusts, but if you use chemical peels together, it will be easier to remove the microcrusts than when you only use Photofacial M22, and melanin will be discharged more smoothly .

Iontophoresis that penetrates beauty ingredients deep into the skin

Iontophoresis is a treatment that allows beauty ingredients to penetrate deep into the skin with a weak electric current. Photofacial M22 treatment makes it easier for the skin to dry, but iontophoresis of moisturizing beauty ingredients such as vitamins can prevent dryness after the treatment. In addition, iontophoresis of beauty ingredients with whitening effects such as tranexamic acid can suppress the excessive production of melanin.

By discharging the existing melanin in Photofacial M22 and suppressing the melanin that will be produced by iontophoresis, a synergistic effect on freckles can be expected .

Laser that destroys melanin

Lasers are used to treat freckles, but each freckle must be irradiated. Basically, laser treatment fees are often calculated per location, so it takes time and money to treat the myriad of freckles.

Photofacial M22 treatments work on a wide variety of freckles, but if the amount of melanin is high or the epidermis layer where melanin is present is different, freckles may remain depending on the number of treatments. It costs money and time to increase the number of treatments in search of the treatment effect.

Laser treatment is expected to be effective in improving freckles remaining after Photofacial M22 treatment, and it is generally said that one treatment works on freckles .

The combined use of Photofacial M22 and laser treatment may be a treatment for sobakasu that reduces the financial and time burden.

Internal and external medicines that can be easily used at home

When freckles are treated with internal or topical drugs, the freckles gradually become thinner over a period of six months to a year, so the visible changes are small and the satisfaction with the treatment tends to be low.

However, more effective freckle treatment can be expected by using Photofacial M22 in combination with internal and external medicines.

The melanin that has come out to the stratum corneum due to the effect of Photofacial M22 is further promoted to be excreted from the body by using a drug such as L-cysteine that promotes turnover. In addition, drugs such as tranexamic acid and vitamin C can suppress the excessive production of melanin, which can reduce the probability of excessive production of melanin and recurrence of freckles after the treatment of Photofacial M22.

Compare with freckle treatments other than Photofacial M22

Difference from pico toning

Pico toning is a treatment that uses a pico laser, and it is a treatment method that makes it possible to irradiate the entire face by irradiating the laser that had to be struck one by one with a low output.

It is recommended to perform 5 to 10 treatments in a cycle of 1 to 2 weeks, and the average treatment fee is 15,000 to 25,000 yen . The pain of the treatment is the same as that of Photofacial M22, and it is said to be a small pain that seems to be repelled by rubber. However, some people find it more painful than Photofacial M22 depending on the output. It is said that the pain can be tolerated without anesthesia, but since there are individual differences in how the pain is felt, cream anesthesia may be used for those who are vulnerable to pain.

Photofacial M22 Pico toning
Frequency of treatment Every 3-4 weeks Every 2-4 weeks
Number of treatments Around 5 times 5 to 10 times
pain Less pain Less pain
downtime Almost none Almost none
Average treatment fee 30,000 yen to 35,000 yen 15,000-50,000 yen

Precautions for freckle treatment with Photofacial M22

Pain of treatment with Photofacial M22

Photofacial M22 is equipped with a function called contact cooling that can irradiate IPL while cooling the skin. In addition, the part that comes into contact with the skin is made of sapphire glass, which has an excellent cooling function, and it is said that pain is less likely to be felt during the procedure by cooling the heat generated by irradiation.

Photofacial M22 downtime

There is almost no downtime in the treatment with Photo Facial M22, and you can make up immediately after the treatment .

Progress of freckles after treatment

Redness occurs

Although there are individual differences, the redness will appear in the part that responds to the IPL wavelength, and it will settle down after a few hours .

The thin scab will come off in about 3 days to 1 week

Image of skin layer

Normally, melanin is present in the basal layer, stratum spinosum, and stratum granulosum of the epidermis, so it is not excreted from the body until it is pushed up to the stratum corneum by turnover.

However, giving heat energy to melanin by irradiating it with IPL light with Photofacial M22 can not only damage melanin, but also damage the melanocytes that produce melanin at the same time.

Melanin and melanocytes damaged by the Photofacial M22 treatment are pushed up to the stratum corneum in 1 to 2 days and become a thin scab called microcrust, which peels off and freckles at the same time as the stratum corneum in about 3 days to 1 week. It will be thinner .

Even if you have redness or micro crust, you can make up as usual .

Frequency and frequency of treatment with Photofacial M22

Attempting to damage all of the melanin and melanocytes in a single procedure puts a lot of strain on the skin, causing inflammation and the risk of post-inflammation pigmentation . Therefore, it is recommended to gradually thin the freckles with about 5 treatments in a cycle of 3 to 4 weeks .

Photo Facial M22 Price Market

The market price of Photo Facial M22 is 30,000 to 35,000 yen for all facial treatments .

If the first treatment is cheaper or cheaper than the market price, the number of irradiations (shots) tends to be small. In addition, if the price is higher than the market price, there may be a set of treatments that can be expected to have a synergistic effect when used in combination with chemical peeling and iontophoresis. There are medical institutions that post the set contents on the HP, but although there is no description of the set contents, there are cases where the price is set higher than the market price, so if you are concerned, is it the treatment fee only for Photofacial M22? , It may be good to check with the medical institution whether the fee is a set of other treatments.

Photofacial M22 is a medical device approved by the Ministry of Health, Labor and Welfare.

Photofacial M22 (including filters 560,590,615,640,695) has been approved by the Japanese Ministry of Health, Labor and Welfare for its safety and efficacy as a medical device. Therefore, the treatment with Photofacial M22 is a medical practice, and only medical institutions can receive the treatment.

How to choose a medical institution when treating freckles with Photofacial M22

For freckle treatment of Facial M22, it is said that it is important to adjust the irradiation output and wavelength according to the skin condition and skin troubles . In addition, the number of irradiations (number of shots) in one treatment is also important, and when irradiating the entire face, 100 to 150 shots is the average number of shots. It is often thought that the more shots there are, the more effective the treatment will be, but too many shots can put a strain on the skin .

In order to realize the effect more, it is recommended to have about 5 treatments, but it seems that there are medical institutions where the doctor examines only the first time and then the nurse performs the treatment. However, since the condition of the skin changes each time the treatment is performed, it is important to determine the output, wavelength, number of shots, etc. to be irradiated each time, and a doctor's examination is required to determine the condition of the skin. In addition, it is said that the treatment effect will differ depending on the doctor's experience.

You can check whether you have a doctor's consultation before each treatment or whether the doctor will perform the treatment on the website of each medical institution or by receiving counseling. The more case photos of Photofacial M22, the more experience you have in the procedure . Also, at the time of counseling, it is safe to choose a doctor who will answer your anxiety, such as whether your symptoms will improve with Photofacial M22.
