Types of pore troubles that can be expected to be effective with pico laser treatment, risks and precautions

Pore becomes noticeable due to various causes such as clogging of sebum and sagging skin . There are various treatments such as laser treatment, IPL treatment, high frequency, hyphen, etc. for cosmetic medicine for conspicuous pores, and improvement can be aimed at by performing the treatment suitable for each cause.

Pico laser is one of the laser treatments and can be expected to be effective for conspicuous pores . By learning more about the characteristics of pico laser and the mechanism that leads to improvement of skin problems, you can understand whether it is a treatment that can be expected to be effective for your own pores.

In addition, by grasping the market price of the treatment fee and the downtime of the pico laser in advance, you can consider whether the treatment method can be received within your own budget, and you can perform the treatment with confidence while planning a specific treatment schedule. You can receive it.

Types of pore troubles classified by the cause of conspicuous pores

The pores become more noticeable as the pore funnel, which is the entrance to the pores, becomes larger . Depending on the cause of the enlargement of the pore funnel, it can be divided into four types: "open pores ", " blackhead pores ", " keratin plug pores ", and " sagging pores ".

Of these, slack pores can be expected to improve with pico laser alone , but other pore problems can be improved by using pico laser in combination with other treatments.

Open pores

Due to dry skin and an unbalanced diet with a lot of lipids, excess sebum is secreted and accumulated in the pores, and the pore funnel, which is the entrance to the pores, becomes larger and the pores become more noticeable . It is a state. Since the amount of sebum is large in the teens to 30s and decreases after the 40s, it can be said that open pores are the pores that occur frequently in the teens to 30s.

Sebum accumulates in the pores and the larger the pore funnel, the more noticeable it becomes. In addition, even if each one is not large enough to stand out, it is often felt that the number of large pores in the pore funnel is increasing.

It may be improved by frequent care such as moisturizing the skin and refraining from eating oily skin, but if left untreated, it may cause oily skin and acne, which makes the skin sticky .

Blackhead pores (strawberry nose)

It is a symptom of pores caused by the darkening of sebum as a result of the sebum accumulated in the pores being oxidized by exposure to ultraviolet rays, stress, and air. When there are many darkened pores in the nose, it looks like a strawberry seed, so it is sometimes called a strawberry nose.

Blackened pores become more noticeable as the pore funnel becomes larger, but not only that, even if the pore funnel is smaller, the more darkened sebum, the more noticeable it tends to be.

The pores are improved by removing the oxidized sebum, but if you try to remove it when the skin is dirty or try to push it out forcibly, it may cause skin troubles such as inflammation and leaving the pores open. Therefore, you need to be careful.

In rare cases, black hair growth, not sebum, may cause darkened pores, and if hair growth is the cause, hair removal can be expected to improve.

Horn plug pores

When the sebum accumulated in the pores and the keratin of the pore funnel are mixed and hardened in the pores, it becomes a keratin plug . The pores caused by these keratin plugs are called keratin plug pores.

The larger the keratin plugs that have accumulated in the pores, the larger the keratin plug pores will be, and the larger the pore funnel will be, making it more noticeable . If the keratin plug remains in the pores for a long period of time, the opening of the pore funnel part will be fixed, and the open and fixed pore funnel part will not shrink easily even if the keratin plug is discharged, and will remain widened. ..

Research results have shown that many keratin plugs occur in the teens to 20s and the pore funnel part suddenly expands and grows larger, and the pore funnel part gradually grows in the 20s to 30s.

As with darkened pores, removing the keratin plugs when the skin is dirty or forcibly removing them with a finger may cause inflammation or leave the pores open.

Sagging pores

Loose pores become noticeable when the skin loses its firmness and sags . From the outside, the skin consists of three layers: the epidermis layer, the dermis layer, and the subcutaneous tissue. The dermis layer is mainly made of collagen, elastin, and hyaluronic acid, and supports the epidermis.

However, as collagen, elastin, and hyaluronic acid decrease with age, elasticity and elasticity decrease, and the skin becomes more prone to sagging. There is data that the pores that increase after the 30s when collagen, elastin, and hyaluronic acid begin to decrease, increase rapidly from the 30s to the 40s, and gradually increase from the 40s to the 50s.

It is said that the improvement of sagging pores can be expected by increasing the growth of collagen, elastin, and hyaluronic acid by the pico laser treatment.

Pico laser characterized by laser irradiation time

Pico laser capable of laser irradiation in picoseconds

The irradiation time per shot when a laser is applied to a substance that causes skin problems such as melanin and hemoglobin is called the "pulse width". The shorter the pulse width, the higher the heat energy that is instantaneously given to the causative substance.

The pulse width is expressed in units such as milliseconds, microseconds, nanoseconds, and picoseconds, and the unit of the shortest pulse width of lasers currently (August 2020) used in aesthetic medicine is picoseconds . A machine that can irradiate a laser in picoseconds is called a "pico laser".

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

Destruction method of causative substances and effects on surrounding tissues, which differ depending on the pulse width

Irradiation with a laser can destroy causative substances such as melanin and hemoglobin, but how they are destroyed depends on the pulse width .

How lasers other than picoseconds destroy causative substances

When the laser is absorbed by the causative substance, the molecule of the causative substance becomes an excited state, which means that the molecule becomes unstable. The excited molecule tries to return to the stable state, and heat energy is generated at that time. The method of destroying the causative substance with this heat energy is called photothermal action, and it is the method of destroying the substance with a laser other than picoseconds .

As the pulse width becomes longer, the thermal energy tends to increase gradually, and as it increases, the thermal energy is diffused to the surrounding tissue and damages the surrounding tissue. The longer the pulse width, the more heat energy is diffused, so the damage to surrounding tissue is proportional to the pulse width . The greater the damage to surrounding tissue, the longer the downtime tends to be.

How pico lasers destroy causative substances

If the pulse width is shorter than picoseconds, the instantaneous thermal energy becomes high, and the causative substance undergoes thermal expansion before the excited molecule stabilizes. When the expanded substance collides with the surrounding tissue, a shock wave is generated in the causative substance , and this shock wave destroys the causative substance . This is called photoacoustic effect .

In the case of laser irradiation with a pulse width of nanoseconds or more, there is a high possibility that the surrounding tissue will be damaged by photothermal action, but in the case of photoacoustic action with a pulse width of picoseconds or less, the generated shock wave will be in the causative substance. Because it stays, it is said that it is unlikely to damage surrounding tissues . The short downtime of pico lasers is said to be due to the low likelihood of damaging surrounding tissues during the process of destroying the causative agent.

Three types of pico laser irradiation methods

Spot irradiation

Spot irradiation is a method of irradiating a laser in a narrow area . Irradiation is performed with the strongest output among the three types of irradiation methods .

By irradiating melanin and hemoglobin, which are the causative substances of skin troubles, with a pinpoint laser to destroy them, it leads to improvement of skin troubles.

Toning irradiation

Toning irradiation intentionally lowers the laser output to irradiate not only the causative substance but also the entire face .

It is said that it can be expected to be effective in improving dullness and tone-up of the skin, but since the output is weak, the destructive action on the causative substance is milder than in spot irradiation.

Fractional irradiation

The skin is roughly divided into the epidermis layer, dermis layer, and subcutaneous tissue from the outside. Fractional irradiation is an irradiation method that intentionally makes fine holes in the dermis layer with a shock wave from a laser, promotes the growth of collagen and elastin, and induces self-renewal of the skin, leading to improvement of skin problems .

In spot irradiation and toning irradiation, the laser is irradiated in a plane without gaps, but in fractional irradiation, a laser with an irradiation diameter smaller than that of the hair is irradiated in dots. When the trace of fractional irradiation is confirmed with a magnifying glass, fine holes are regularly opened in dots like the trace of a stamp injection (BCG injection).

Types and mechanisms of pores that can be expected to be effective with pico lasers

Pico laser treatment for pores is performed by fractional irradiation .

The skin consists of layers of epidermis layer, dermis layer, and subcutaneous tissue from the outside. Among them , the important layer that supports the epidermis is the dermis layer , and it is said that the thicker the dermis layer, the more elastic and elastic the skin is. I will. The dermis layer is made up of collagen, elastin, and hyaluronic acid, which are produced by the fibroblasts present in the dermis layer .

Fractional irradiation of pico laser can evenly make fine holes in the dermis layer to stimulate fibroblasts and promote the production of collagen, elastin, and hyaluronic acid . By adjusting the output of the pico laser that irradiates according to the degree of sagging of the skin, it stimulates fibroblasts, and by producing collagen, elastin, and hyaluronic acid, the skin becomes firm and elastic, and it is expected to be effective for sagging pores. It is said that it can be done.

In addition, it is said that the dermis layer becomes thicker by promoting the production of collagen, elastin, and hyaluronic acid in the dermis layer, and it is expected that the open pores will shrink after removing sebum, keratin plugs, and darkening.

Treatment that can be expected to have a synergistic effect when used together

Hydra Facial

Hydra Facial is a machine-based treatment that uses four types of agents containing beauty ingredients to lift sebum and dirt and cleanse deep into the pores .

The four types of drugs include ingredients that remove dirt and improve wrinkles, ingredients that remove dead skin cells, ingredients that remove keratin plugs and excess sebum to moisturize, and ingredients that soothe skin inflammation and oxidize. It contains ingredients that prevent (antioxidant effect), and can remove unnecessary sebum, keratin plugs, and darkening while moisturizing and soothing the skin .

After removing the sebum, keratin plugs, and darkened sebum that cause open pores, keratin plug pores, and darkened pores, you can aim to reduce the pores by irradiating with a pico laser .

In addition, the antioxidant ingredients used in Hydra Facial have the effect of suppressing skin oxidation that causes spots, wrinkles, sagging, and dullness, and can be expected to improve skin problems other than pores.

Chemical peeling

Chemical peeling is a treatment that promotes skin regeneration by applying the drug directly to the skin and peeling it off thinly . By peeling before the pico laser treatment, it is possible to remove sebum, keratin plugs, and darkened sebum from open pores, keratin plug pores, and darkened pores.

By irradiating with pico laser after removing sebum, keratin plugs, and darkening of sebum , pores are reduced, and improvement of open pores, keratin plug pores, and darkening pores can be expected.

In addition, since chemical peels contain a component that suppresses the secretion of sebum, it is said that the excess secretion of sebum can prevent the formation of keratin plugs again, and the accumulation of sebum that can be prevented from oxidizing and darkening .

What you need to know before receiving pico laser pore treatment

Pain during the procedure

When aiming to improve pores by pico laser treatment, it is said that the pain is repelled by rubber, although there are individual differences.

If you are worried that you are vulnerable to pain, you can relieve the pain by undergoing treatment at a medical institution that uses an anesthetic cream .

Downtime, risks and side effects

When the pico laser is fractionally irradiated for the treatment of the pores , redness appears at the treatment site . Although there are individual differences, it is said that the redness will be reduced from a few hours to the next day. If the skin is slack, the laser output may be increased, and if the output is increased, redness may remain for about a week, but it is said that there are almost no risks or side effects when applying pico laser to the pores.

Recommended number and frequency of treatments

When performing fractional irradiation with a pico laser, it is recommended to perform 1 to 5 times . When performing multiple treatments, it is recommended to leave a period of about one month before the next treatment .

Price quote

For fractional irradiation of pico laser, the market price for all facial treatments is about 30,000 to 45,000 yen .

Treatments aimed at improving pores are not covered by insurance for beauty purposes and are fully borne by you.

Those who cannot receive the treatment

  • Those who are tanned or plan to get tanned
  • Pregnant and lactating
  • Those with scars or herpes on the treatment site
  • Those with a history of epileptic seizures
  • Those with photosensitivity
  • Those with diabetes, heart disease, brain disease, malignant tumor

Treatments other than pico laser that can be expected to improve pores

Keratin plug removal

A treatment that can be received at cosmetology dermatology or dermatology, where the keratin plug can be removed without giving unnecessary irritation to the pores by sucking while applying steamer steam after applying a special solvent to soften the keratin plug. is.

In addition, it is possible to remove not only keratin plugs but also sebum that causes open pores and oxidized sebum that causes darkened pores, which can be expected to improve open pores, darkened pores, and keratinized pores .

HIFU treatment

Hythe treatment is a cosmetological treatment that irradiates the fascia that covers the facial muscles called the SMAS layer (superficial fascia group) under the skin with ultrasonic waves to contract it and pulls up the slack from under the skin . .. It is said that improving slack leads to improvement of slack pores caused by slack .

In hyphen treatment, not only slack pores but also lift-up (tightening) that raises slack can be expected to have a small face effect and a firming effect on the skin . In addition, since it can destroy the fat cells of subcutaneous fat, it is also possible to aim for partial thinning of the area of concern .

High frequency treatment

High-frequency treatment warms the dermis layer with a constant frequency (vibration of the waveform) irradiated from a dedicated machine and stimulates fibroblasts, which are cells that produce collagen, elastin, and hyaluronic acid, to stimulate collagen, elastin, and hyaluronic acid. It is a treatment that promotes the production of collagen .

By promoting the production of collagen, elastin, and hyaluronic acid, which are the foundations of the skin, slack is eliminated and slack pores can be expected to improve . In addition, by warming the deep part of the face and body, blood flow and lymphatic flow are promoted and waste products are discharged smoothly, which is said to increase metabolic power and have a slimming effect .

IPL (light) treatment

Laser therapy approaches the causative agent at one wavelength, but the light energy used in IPL (light) therapy has multiple wavelengths . The wavelength of light energy used in aesthetic medicine is around 500nm to 1200nmm, and the IPL treatment machine cuts unnecessary wavelengths that are not absorbed by the causative substance and irradiates the treatment site.

Irradiation with IPL stimulates the dermis layer to promote the production of collagen, elastin, and hyaluronic acid, and is said to be able to improve sagging, and is expected to have an effect on sagging pores .

In addition, since one machine can irradiate multiple wavelengths, it is possible to approach not only pores such as melanin, which causes dark spots and dull skin, but also other skin problems .

Dermapen 4

Treatment with Dermapen 4 is a treatment that causes the "natural healing power" that is inherent in humans, and is a treatment that intentionally makes fine needle holes on the skin surface with a needle as fine as a hair.

The skin with needle holes secretes growth factors that activate the activity of cells in an attempt to heal the wound. Growth factors promote the production of collagen, elastin, and hyaluronic acid, and by improving sagging, it can be expected to have an effect on sagging pores .

It also has the effect of activating turnover, which is the rebirth of skin cells. When the turnover cycle is disturbed, the keratin that is originally peeled off and discharged accumulates in the pores and mixes with sebum, causing keratin plugs. By activating the turnover and returning it to the normal cycle, it can be expected to suppress the cause of keratin plug formation and lead to skin where keratin plug pores are less likely to form.

How to choose a medical institution to receive pore treatment with pico laser

When performing a treatment with a pico laser, it is necessary to adjust the laser output according to the condition of the pores . In addition, if not only pores but also spots, freckles, chloasma, etc. are present, the irradiation method must be changed between the treatment for pores and the treatment for spots, freckles, chloasma, or pico laser irradiation is appropriate. It may not be.

Not only the desire to improve pores with pico laser, but also the optimal treatment method by examining the condition of the skin and confirming whether the pico laser treatment is really suitable and whether there is no problem with fractional irradiation. It is safe to consult with the medical institution where the doctor who proposes is enrolled.
