Photofacial M22 is an IPL (light) treatment machine that can be expected to improve various skin problems. Generally, it is known as a machine that improves skin quality such as age spots, freckles, reddish face, pore shrinkage, and skin texture, but it is also expected to be effective in soothing acne and improving acne scars . ..
There are various treatment methods for acne, but in the case of acne treatment with Photofacial M22, it is possible to aim not only for acne but also for improving skin quality . However, Photofacial M22 is not a treatment that can improve all acne symptoms. Therefore, it is important to know in advance the types of acne that can be expected to be effective with Photofacial M22 and the types of acne that cannot be expected to be effective .
In addition, by understanding the treatment methods for acne other than Photofacial M22, you can aim to improve the symptoms with the treatment method that suits your own acne symptoms.

The pores are clogged and sebum accumulates in the hair follicles, causing acne.
The cause of pore clogging is that the turnover cycle, which is the metabolism of the skin, is disturbed by lifestyle-related habits such as an unbalanced diet and lack of sleep. When the turnover cycle is disturbed and stagnant, old keratin accumulates on the inner upper part of the pores and clogs the pores .
Normally, sebum is secreted from the pores, but when the pores are clogged , sebum accumulates around the hair follicles of the hair growth tissue that surrounds the roots, creating a small bulge on the skin . This small swelling is the early stage of acne.
Using the sebum accumulated in the hair follicles as a nutrient source, P. acnes, which is an indigenous bacterium on the skin, proliferates, and an enzyme called porphyrin, which is generated by the metabolism of the P. acnes, decomposes the sebum accumulated in the pores and free fatty acids Is generated. Free fatty acids are one of the fatty acids that are constituents of lipids such as sebum, and have the property of stimulating hair follicles and causing inflammation. Inflammation also occurs when neutrophils and lymphocytes, which are one of the white blood cells, kill and attack P. acnes.
When inflammation is caused by free fatty acids and neutrophils / lymphocytes , acne becomes red and pus (pus) appears. If the inflammation continues, the hair follicles may be destroyed and the surrounding dermis may be damaged, resulting in severe acne.
There are several types of acne depending on the symptom, and in addition to the fact that each has a medical name and a general name, the appearance of the acne also differs depending on the symptom.
When the turnover cycle, which is the metabolism of the skin, is disturbed due to irregular lifestyles, the pores are clogged and sebum accumulates in the hair follicles, causing a small swelling on the skin. Small pimples on the skin are pimples that are commonly referred to as "white pimples" or medically called "closed comedones".
White acne tends to improve by removing dead skin cells that have accumulated in the pores and clearing the clogging of the pores .
As white acne progresses and the amount of sebum in the hair follicles increases, the keratin that caused the clogging of the pores is expanded and the pores expand. As the pores expand, the keratin and sebum in the pores react with oxygen in the air and oxidize, turning black. The condition in which the pores are opened and blackened is generally called "black comedone", and medically called "comedone open".
When the dead skin cells and sebum in the pores are drained, the black acne will soothe .
When the pores are clogged and sebum accumulates, P. acnes, which is an indigenous bacterium on the skin, grows using sebum as a nutrient source. Proliferated P. acnes excretes an enzyme called porphyrin by metabolism, and when this porphyrin breaks down sebum, it produces free fatty acid, which is one of the fatty acids.
Free fatty acids have the property of stimulating hair follicles and causing inflammation, so "red papules", which are acne with redness on the skin due to inflammation, are medically "red papules". Causes acne called. Inflammation may also occur when neutrophils and lymphocytes, which are one of the white blood cells, kill and attack P. acnes that have grown inside the pores, and may progress to red acne.
If the inflammation caused by free fatty acids and neutrophils / lymphocytes subsides, the symptoms will not become severe .
When red acne progresses and a large amount of P. acnes killed by neutrophils and lymphocytes and neutrophils and lymphocytes that have collapsed due to the fight against P. acnes are generated, pus is produced in addition to redness due to inflammation. It will be accompanied by acne. The condition in which the pus that collects at the top of the acne becomes visible is the acne that is generally called "yellow acne" or medically called "pustules". The area where the pus has accumulated looks yellow, but the acne itself is reddish due to inflammation.
If the accumulated pus is drained and the inflammation caused by free fatty acids and neutrophils / lymphocytes subsides, the yellow acne will subside , but it may become acne scars .
If inflammation continues from the state of yellow acne, free fatty acids damage the walls of hair follicles and tear them, and sebum, pus, and blood accumulated in the pores from the torn part enter the dermis and form a bag. .. It is generally called "purple acne" and is medically called "cyst".
In addition, sebum, pus, and blood that collect in a bag may solidify, causing the acne area to become lumpy. A lumpy acne is also commonly referred to as purple acne, but medically it is called "induration".
If the condition is not inflamed, such as white or black acne, or if the symptoms are minor, such as red acne, there are few acne scars. However, when the inflammation becomes severe, such as yellow and purple , acne scars are more likely to remain .
There are five types of acne scars .
Photofacial M22 is one of the medical machines that irradiate the energy of electromagnetic waves called IPL (Intense Pulsed Light). By irradiating and damaging IPL that acts only on specific substances such as melanin and hemoglobin, it leads to improvement of skin problems such as age spots, freckles, reddish face, pores, skin texture, and acne.
The IPL contains multiple wavelengths. Energy such as IPL has the property of a waveform, and the length of a waveform that repeats peaks and valleys (or valley to valley) is called the wavelength, and the unit of wavelength is nanometers, which is one billionth of a meter. Notated as meters (nm).
The wavelengths used in Photofacial M22 range from 515nm to 1200nm, and the longer the wavelength, the deeper the skin can be delivered. In addition, by using 9 types of filters properly, it is possible to cut wavelengths that are unnecessary for the treatment and irradiate wavelengths suitable for each skin problem that you want to improve, such as acne and age spots, so you can expect improvement of various skin problems.
With Photofacial M22, it is possible to treat the following acne symptoms.
By using a 400nm-600nm acne filter, it is possible to deliver the energy of IPL that acts on the enzyme porphyrin excreted by the metabolism of P. acnes. Porphyrins that receive the energy of IPL have the property of producing singlet oxygen (Ichijukousanso), which is one of the active oxygens, and singlet oxygen has the function of killing acne bacteria .
By reducing P. acnes, neutrophils and lymphocytes are reduced from the inside of the hair follicle, and inflammation is suppressed . When the amount of porphyrin excreted from P. acnes decreases, the amount of free fatty acids produced by the decomposition of sebum by porphyrins also decreases, so inflammation caused by free fatty acids is suppressed and red acne can be expected to improve .
In addition, by using a filter for acne of 800 nm to 1200 nm, it can be expected to have the effect of constricting deep blood vessels that have the role of feeding nutrients to the sebaceous glands, suppressing the secretion of sebum, and preventing the recurrence and renewal of sebum . ..
The acne scars that can be improved by Photofacial M22 are post-inflammatory erythema (enshogokouhan), which has redness after the inflammation has subsided, and inflammation that has become pigmented and becomes like spots after the inflammation has subsided. Post-inflammatory hyperpigmentation (enshogoshikisochinchaku).
Post-inflammatory erythema can be expected to have the effect of making redness less noticeable by contracting the expanded capillaries with the IPL energy emitted from Photofacial M22. Since the wavelength to be used is selected according to the depth of the skin where the widened capillaries that cause redness are present, a filter other than that for acne may be used.
For post-inflammatory hyperpigmentation, the IPL energy of Photofacial M22 is absorbed by melanin, which is the cause of pigmentation, to generate heat energy, which damages melanin and promotes its excretion to the outside of the body . I will guide you. As with post-inflammatory erythema, the wavelength used in the procedure depends on the depth of the skin where the melanin that causes pigmentation is present.
Photofacial M22 (including filters 560,590,615,640,695) is a medical device that has been approved by the Ministry of Health, Labor and Welfare for its safety and efficacy. Therefore, the treatment with Photofacial M22 is a medical practice and can only be taken at a medical institution.
|Approval in Japan||22500BZX00469000|
Photofacial M22 is equipped with a function called contact cooling that can irradiate IPL while cooling the treatment site. In addition, the part that comes into contact with the skin when irradiating the IPL is made of sapphire glass, which has an excellent cooling function, and the heat generated by the irradiation of the IPL can be cooled and relieved, so it is difficult to feel pain during the procedure. It has been.
Treatment of acne with Photofacial M22 is a treatment with almost no downtime, and it is possible to apply makeup immediately after the treatment .
The number of treatments required to treat acne with Photofacial M22 varies from person to person depending on the degree of inflammation of the acne, the depth of the skin where the melanin that causes acne scars is present, and the amount of melanin that remains. ..
The treatment of acne with Photofacial M22 is not covered by insurance, so you will have to pay the full cost. In the case of full-face treatment, the market price per treatment is 15,000 to 30,000 yen .
In addition, if there are few acne or acne scars, an irradiation method called "spot irradiation" that irradiates the IPL in a narrow area is suitable, and you may be able to receive the treatment at a relatively low fee. If you wish to have spot irradiation, please check with your medical institution in advance if there is an applicator dedicated to spot irradiation.
|Types of acne treatment||Types of acne that can be expected to improve|
|Internal / external medicine||All acne, acne scars (post-inflammatory erythema, post-inflammatory hyperpigmentation, hypertrophic scars)|
|Chemical peeling||White / black / red acne, acne scars (atrophic scars)|
|Laser treatment||Red acne, acne scars (post-inflammatory hyperpigmentation, post-inflammatory erythema, atrophic scars)|
|injection||Purple acne (cyst), acne scar (atrophic scar, hypertrophic scar, keloid)|
Internal and external medicines are often used in the treatment of acne. There are a wide variety of medicines, and each ingredient has different effects such as antibacterial, bactericidal, and exfoliation of keratin. By using it according to the symptoms of acne, it suppresses inflammation of acne and eliminates clogging of pores. You can expect effects such as
The main types of internal and external medicines used in the treatment of acne are as follows.
・ Doxycycline ・ Kinocycline ・ Roxithromycin ・ Faropenem ・ Tetracycline ・ Erythromycin ・ Clarithromycin ・ Lepofloxacin ・ Tosufloxacin ・ Ciprofloxacin ・ Lomefloxacin ・ Sefloxim axetyl ・ Tranilast ・ Low-dose estrogen, spironolactone ・ Vitamin Oral medication
・ Clindamycin ・ Benzoyl peroxide ・ Adapalene ・ Nadifloxacin ・ Ozenoxacin ・ Ibuprofen piconol cream ・ Azelaic acid external use ・ Vitamin C external use ・ Sulfur preparation external use
All medicines are covered by insurance and can be prescribed by a dermatologist .
However, if you use the same drug for a long period of time , the effect may be diminished due to the resistance of P. acnes to the drug . In addition, since internal and external medicines have side effects such as dryness, discomfort, irritation, skin exfoliation, erythema, pruritus, and contact dermatitis , the use of internal and external medicines may be discontinued if side effects occur. There is.
Even if you wish to receive treatment with internal or external medicine, other treatments may be indicated if you are not fit for your constitution due to side effects.
Chemical peeling, which is a treatment that promotes skin regeneration by applying the drug directly to the skin and peeling it off thinly, is applied to acne other than purple acne and atrophic scars, which are acne scars with dented skin. You can expect the effect.
To eliminate the clogging of the pores by chemical peeling, by prompting the discharge of accumulated have sebum and pus, there is action to suppress the growth of acne bacteria inhibiting the progression of acne.
For atrophic scars, after peeling the skin thinly with chemical peeling, the skin surface becomes flat and the dents are reduced in the process of skin regeneration .
When aiming to treat acne with chemical peels, drugs such as glycolic acid, macrogol salicylate, and ethanol salicylate are used, but the thickness of the skin that can be peeled off depends on the drug. Therefore, the drug used in the procedure depends on the depth of the skin where the symptoms of acne are present.
In addition, since the treatment is not covered by insurance, you will be responsible for all costs.
Laser, which is one of the electromagnetic waves, is energy that has the property of artificially extracting a specific wavelength from various wavelengths of light and amplifying it so that it travels sharper and in a straight line than light. The IPL contains multiple wavelengths, but each laser has a specific wavelength, and the name of the laser differs depending on the wavelength.
When a laser is absorbed by a target substance such as melanin or hemoglobin, it becomes heat energy and has the effect of denaturing or destroying the target substance .
What kind of acne can be expected to be effective depends on the wavelength of the laser to be irradiated as follows.
|wavelength||Laser name||Types of acne that can be expected to improve|
|1064nm||Nd: YAG laser||Red / yellow acne, acne scars (post-inflammatory hyperpigmentation / atrophic scars)|
|532nm||KTP laser||Red / yellow acne|
|585nm ~ 595nm||Pulse die laser||Red / yellow acne, acne scars (post-inflammatory erythema)|
|810nm ~ 1450nm||Diode laser||Acne scars (atrophic scars)|
Laser treatment for acne is not covered by insurance, so you will be responsible for all costs.
When the wavelength of the laser is absorbed by the porphyrin excreted by the metabolism of P. acnes, it produces singlet oxygen, which is one of the active oxygen, and the generated singlet oxygen kills P. acnes . By reducing P. acnes, improvement of red and yellow acne accompanied by inflammation can be expected.
Post-inflammatory hyperpigmentation, which is pigmented and looks like spots, and post-inflammatory erythema, which is reddish, are caused by melanin and hemoglobin. The wavelength of the laser is absorbed by melanin and hemoglobin, which are the causes of acne scars, and becomes heat energy, which destroys melanin and hemoglobin , leading to improvement of acne scars .
In addition, for atrophic scars, which are acne scars with a dented skin, irradiating the dermis with a laser to generate heat energy has the effect of promoting collagen production and promoting the reconstruction of skin tissue. It can be expected to improve by flattening the dents on the skin surface .
By injecting a drug into purple acne (cyst) and acne scars, it can be expected to suppress inflammation of acne and improve atrophic scars, which are acne scars with dented skin.
It is possible to reduce the size of cysts by injecting steroids, which are said to have an anti- inflammatory effect , on purple acne. In addition, hypertrophic scars and keloids can be improved by injecting steroids.
For atrophic scars, injection of collagen or hyaluronic acid can be expected to reduce dents on the skin surface . However, collagen and hyaluronic acid injections for acne treatment are not covered by insurance, so you will be responsible for all costs.
The Photo Facial M22 has 9 types of filters, including a filter for acne, but there are also multiple types of light guides for the parts that come into contact with the skin when irradiating. There are three types: a 15 mm x 35 mm square type used for wide areas such as the forehead and cheeks, an 8 mm x 15 mm square type used for small areas such as the eyes and mouth, and a 6 mm diameter round type that can spot-irradiate narrow areas.
However, the types of filters and light guides handled by medical institutions differ . Therefore, it is important to check in advance whether there is a filter dedicated to acne and a light guide that can perform the optimal treatment for the area where acne is a concern. Please check the homepage of each medical institution or the contact information for the types of filters and light guides that we handle.
In addition, as a general rule, a doctor's examination is required before the treatment, but if you contract for Photofacial M22 treatment in multiple sets, the second and subsequent treatments will not be examined by the doctor, and the nurse will see the symptoms. However, there are also medical institutions that perform treatments. Even if you have contracted for multiple sets of treatments, you can aim for more effective treatment by choosing a medical institution that has a doctor's consultation before each treatment .
