IPL (light) treatment has been used since the 1990s for skin treatments such as tattoos, hair loss, and pigmented lesions with excess melanin and hemoglobin such as bruises. It is a treatment method that attracted attention in cosmetology in the latter half of the 1990s and has been reported to have various clinical effects since around 2000. It is said that Intense Pulsed Light, an energy with multiple wavelengths, acts on melanin and hemoglobin, and can be expected to rejuvenate the skin .
However, one treatment does not dramatically rejuvenate the skin, and it is recommended that you take multiple treatments to see the effect. This time, I will explain the definition of the case where the IPL treatment is stopped in the middle, assuming that the recommended number of treatments are not completed and the treatment is stopped.
Some people think that if they stop IPL treatment in the middle, their skin will become extremely old, but that is not the case. If you stop IPL treatment in the middle, you can receive treatment without anxiety by knowing exactly what kind of effect it will have on your skin .

For skin problems that can be expected to be effective with IPL treatment, laser treatment can also be expected to be effective, but in the case of laser treatment, unlike IPL treatment where multiple treatments are recommended, one treatment can be expected to be effective. ..
Laser treatment that is effective for the same skin troubles with one treatment has already been developed, but the reason why IPL treatment was developed is because of the change of mind of those who want to improve skin troubles . In recent cosmetology, not only the effect on skin problems but also the quality of life is becoming more important, such as the problem of not being able to make up immediately after the procedure due to work. ..
In the case of laser treatment, the downtime after the treatment is relatively long, it is not possible to make up on the treatment site, and it is necessary to apply tape to protect the laser-irradiated area until the scab is removed. You can't live the street life. There is also the risk of post-inflammatory hyperpigmentation, which causes the laser-irradiated area to become pigmented like spots after downtime.
On the other hand, in the case of IPL treatment, it is possible to perform treatment according to recent needs, such as make-up immediately after treatment, not damaging the skin as much as applying post-treatment tape, and low risk of post-inflammatory hyperpigmentation . As a result, it has been selected as a treatment for skin problems, and clinical results have increased, and it has been established as an improvement treatment for skin problems along with laser treatment.
IPL (Intense Pulsed Light) is a type of electromagnetic wave like a laser. Electromagnetic waves are classified into gamma rays, X-rays, ultraviolet rays, visible rays, infrared rays, microwaves, and high frequencies according to the difference in wavelength. Wavelength is the length of a wave that repeats peaks and valleys, from peak to peak (or valley to valley), and is expressed in units of nanometers (nm).
The longer the wavelength, the deeper the skin can deliver the energy of electromagnetic waves. Energy is absorbed by target substances such as melanin and hemoglobin and converted into heat energy . The converted thermal energy can damage or denature the target substance . This is called thermal action .
There is only one type of laser wavelength, and the name of the laser is determined for each wavelength, but the IPL wavelength used in cosmetology has multiple wavelengths, around 500nm to 1200nmm.
The target substance must be irradiated with the optimum wavelength to absorb energy and cause thermal action. The IPL treatment machine is equipped with a filter that cuts off unwanted wavelengths in order to irradiate the target substance with the appropriate wavelength .
Filters that cut unnecessary wavelengths include machines that are embedded in the handpiece that irradiates the IPL, and machines that are removable. The type embedded in the handpiece can irradiate one type of wavelength, and the removable type has multiple wavelengths that can be irradiated depending on the number of filters.
In IPL treatment, the strength of the heat effect on the target substance changes depending on the pulse width , which is the length of each IPL irradiation, and the output, which is the energy density of the IPL emitted per square centimeter .
The pulse width is expressed in ms (milliseconds), which is 1/1000 second. The shorter the pulse width, the higher the instantaneous heat energy (peak power), and the stronger the thermal effect on the target substance. I will.
The output of IPL is expressed in units of J (joules) / ㎠, and the higher the output, the higher the density of energy emitted per unit area, and the stronger the thermal effect on the target substance.
The stronger the heat action, the more damage and degeneration of the target substances will cause a big change in the skin troubles, but if the heat action is too strong, the risk of skin burns increases. The pulse width and output are set in consideration of both the effect and risk for skin problems, and the treatment is performed.
Spots, freckles, and chloasma are called photoaging, and the colors of spots, freckles, and chloasma are darkened mainly by ultraviolet rays . In IPL treatment, melanin, which is the cause of color, is damaged by heat and excreted from the body, which can be expected to have the effect of lightening the color.
However, it is known that liver spots become darker not only with ultraviolet rays but also with rubbing of the skin or treatment with a laser that has a strong thermal effect in cosmetology . Therefore, even during IPL treatment, the treatment is performed while adjusting the output so that the color of the chloasma does not become dark.
Post-inflammatory hyperpigmentation is the process of hyperpigmentation, like age spots, after the skin is injured and healed. It occurs when more melanin is produced in an attempt to protect damaged skin cells . It is known to occur after acne and abrasions, but it can also occur with cosmetological treatments that have a strong thermal effect, such as lasers.
Post-inflammatory hyperpigmentation is the so-called scar, which is a condition in which the barrier function of the skin is reduced and water is easily lost, and various substances such as allergens easily enter the body through the skin. Highly irritating treatments can cause more damage to the skin and worsen post-inflammatory hyperpigmentation, so be careful not to irritate the pigmented area more than necessary during IPL treatment. The output is weakened and the treatment is performed carefully.
The above four types of skin problems are mainly caused by hemoglobin, which is the red pigment of red blood cells contained in the blood . Hemoglobin increases due to the dilation and proliferation of capillaries, which is a visible symptom. IPL treatment causes a thermal effect on hemoglobin and constricts blood vessels, which can be improved.
Rosacea not only makes the face red due to the dilation and proliferation of capillaries, but also causes small pimples on the skin. Rosacea is divided into four stages according to the symptoms, and it is the first stage of rosacea that can be expected to be effective with IPL treatment.
Stage 1: The skin on the cheeks and nose may become red and tingling. It is also called the rosacea progenitor period.
Stage 2: The skin becomes red and swollen, and small blood vessels can be seen just below the epidermis. Also called the vascular phase.
Stage 3: Also called the inflammatory stage, which is a condition in which not only redness of the skin but also small pimples occur. The pimple may also contain a small amount of pus.
Stage 4: The skin around the nose becomes thick and red and looks like a dumpling nose. It is also called the advanced stage, and improvement requires surgery to scrape off the outer layer of the skin with a metallic instrument or surgery to scrape off excess tissue.
The treatment to improve the above skin problems is called Skin Rejuvenation. Skin Rejuvenation is "skin rejuvenation treatment" in Japanese.
Opening of pores, loss of skin elasticity, irregular texture, and wrinkles (very shallow) are mainly due to a decrease in collagen and elastin, which are proteins that support the skin . Another cause is that the turnover cycle is disturbed by lifestyle-related habits such as an unbalanced diet and lack of sleep.
In IPL treatment, the heat action on the dermis, which has the function of producing collagen, can promote the production of collagen, and the heat action on the epidermis can also promote turnover at the same time, so that skin problems can be improved. Can be expected.
IPL treatment is said to have a weaker thermal effect on the target substance than laser treatment, and the effect of one treatment is small, and multiple treatments are recommended . Although it depends on the type of skin trouble, it is recommended to perform the treatment about 5 times every 3 to 4 weeks, and the more times the treatment is performed, the more effective the treatment tends to be.
However, clinical results have been reported that when the treatment is performed every 3 to 4 weeks, the peak effect is reached after about 10 consecutive treatments . If the recommended number of treatments for skin problems is exceeded after every 3 to 4 weeks, the skin maintenance effect can be expected by performing the treatment again after 3 months to 6 months before the next treatment. It is said.
It is recommended to perform 3 to 5 treatments every 3 to 4 weeks to improve age spots, freckles, pores, decreased skin elasticity, irregular texture, and wrinkles (very shallow ones).
If you stop the procedure in the middle, there is a high possibility that you will not get the expected effects such as thinning of spots and freckles, tightening of pores, and elasticity of the skin.
Since the color of chloasma becomes darker when the skin is rubbed or when it receives strong stimuli such as cosmetological treatment, treatment using external or internal medicine was originally recommended. However, with the evolution of the IPL treatment machine, it has become possible to perform the treatment with a very weak output, and the risk of darkening of the liver spots due to the treatment has decreased, so IPL treatment has also been used. It was.
However, IPL treatment alone does not aim to improve chloasma, and it is recommended to use it in combination with topical and oral medications. When IPL treatment is performed in combination with topical or internal medicine, the effect of thinning liver spots can be expected by IPL irradiation about 3 times.
If you stop the IPL treatment in the middle, there is a disadvantage that it takes time to improve the chloasma.
For post-inflammatory hyperpigmentation, as with chloasma, treatment with topical or oral medications was recommended, but IPL treatment with a very weak output can be expected to have the effect of reducing pigmentation. ..
It is said that a synergistic effect can be expected by using both external and internal medicines during IPL treatment, and post-inflammatory hyperpigmentation can be improved in a shorter period of time than when only one treatment is performed.
Depending on the degree of skin damage, it is necessary to carefully adjust the wavelength, pulse width, and output, so the number of treatments varies from person to person. The doctor's diagnosis will determine the recommended number of treatments, but if you stop halfway through, it is more likely that the pigmentation will not diminish .
In addition, if you stop IPL treatment and continue treatment with only topical or internal medicine, the period until improvement may be longer .
IPL treatment has less heat and less downtime than laser treatment. Makeup is possible immediately after the procedure, and there is no need to apply tape .
IPL treatment and laser treatment lead to improvement of skin troubles due to heat action, but if the heat action is strong, there is a risk of damaging the skin around the treatment site.
Clinical results have shown that IPL treatment has a lower risk of heat burns and post-inflammatory hyperpigmentation than laser treatment because it can irradiate the output weakly.
There are treatments that can be expected to have a synergistic effect on skin problems when used in combination with IPL treatment. Peeling, iontophoresis, laser treatment, internal and external medicines are often used in combination, and some medical institutions have a set of IPL treatment and combined treatment.
In laser treatment, which is expected to improve skin problems similar to IPL treatment, irradiation is performed using one type of wavelength. Therefore, in most cases, there is only one type of skin problem that can be expected to improve.
On the other hand, IPL treatment can improve multiple skin problems with a single treatment using multiple wavelengths. For example, when the treatment is performed for the purpose of improving the spots, first irradiate with a wavelength that damages the melanin that causes the spots. Next, replace the filter that cuts unnecessary wavelengths and irradiate the wavelengths that work on the dermis. As a result, you can expect not only the effect of thinning the spots, but also the effect of promoting the production of collagen, adjusting the texture, and improving the firmness of the skin with one treatment.
There are various types of treatments to improve skin problems, such as laser treatment, high-frequency treatment, and HIFU treatment, in addition to IPL treatment, just by irradiation treatment . Depending on the treatment, the fee, the period until improvement, and the risk differ, so many people may not be able to decide which treatment to perform.
The number of treatments and fees required to improve skin problems, the period until improvement, and the risks vary from person to person depending on the person's physical condition, skin type, and the cause of the skin problems. If you are uncertain about which treatment to perform , consult a medical institution to examine the condition of your skin and propose the most suitable treatment according to your wishes, such as wanting to do it cheaply or quickly. you can get.
