Water light injection is a treatment that aims to improve skin quality by directly injecting a drug containing beauty ingredients such as hyaluronic acid, vitamins, and antioxidants into the skin .
In South Korea, moisturized and youthful skin with firmness and luster is called "water light skin (Murguanpib)". That is the origin, and it came to be called "water light injection" in Japan.
Depending on the drug used , water light injection has different expected effects such as hydration of the skin, elimination of dullness, improvement of elasticity, improvement of wrinkles and fine wrinkles, and by receiving it regularly and repeatedly, the youth of skin cells can be reduced. It is also effective for maintenance .
Knowing the effects of each drug and the recommended number of treatments, and choosing the drug that suits you will lead to a satisfactory treatment effect.
In addition, by knowing in advance the downtime, side effects, and cost quotes of water light injection, you can receive the treatment with peace of mind.
Table of contents
The skin of the human face is about 2 mm thick and is composed of three layers, the epidermis layer, the dermis layer, and the subcutaneous tissue, from the outside. Just below the epidermis layer, which is about 0.2 mm, is a layer called the dermis layer, which occupies most of the skin and is rich in collagen.
The skin has a synergistic structure consisting of the stratum corneum, epidermis, dermis, and deeper subcutaneous tissue of Tokoro from the outside. Excluding subcutaneous fat, the average thickness is about 2 mm, and in adults, when the entire skin is spread out, it has an area of about one tatami mat, and the weight is about 16% of the body weight including the subcutaneous tissue. ..
In the dermis layer, collagen, which is a strong fibrous protein, elastin, which is an elastic fibrous protein, and hyaluronic acid, which can store abundant water, are present.
Elastin bundles the reticulated collagen together to give elasticity to the dermis layer with a spring-like structure, and hyaluronic acid fills the gap between collagen and elastin while holding water, acting like a cushion. I will. Therefore, the thicker the dermis layer, the more elastic and fresh the skin is.
However, with age, the ability to produce collagen, elastin, and hyaluronic acid declines, and when the mesh-like, spring-like structure loosens, the skin loses elasticity and wrinkles and sagging are thought to occur.
Even if you use basic cosmetics containing these ingredients in anticipation of the growth of collagen, elastin, and hyaluronic acid, the barrier function works on human skin, so beauty ingredients such as lotion and serum are on the dermis. It stays on the surface of the layer and does not penetrate into the dermis layer.
In addition, hyaluronic acid supplemented with food and supplements is said to be difficult to be absorbed in the intestine due to its large molecule.
Therefore, by injecting a drug containing beauty ingredients such as hyaluronic acid into the inner part of the epidermis layer to the dermis layer evenly and finely by water light injection, the beauty component of the drug that originally does not penetrate by just applying it is deep in the epidermis layer. -Can penetrate firmly into the dermis layer .
Water light injection uses a needle to inject not only hyaluronic acid but also various highly effective skin-beautifying agents directly into the deep to dermis layer, such as spots, wrinkles, fine wrinkles, acne, and rough skin. It is a treatment method that leads to improvement .
By performing the water light injection with a dedicated machine, it is possible to inject without leaking the drug solution from the skin while significantly reducing the pain during the treatment compared to the case of manual injection.
Originally, the human body has a natural healing power to heal wounds and injuries. For example, when injured, Casabuta is formed over several days, and when it comes off, new skin is regenerated.
Wound healing is a physiological process, involving three successive and overlapping phases—hemostasis / inflammation, proliferation, and remodeling—to maintain the integrity of skin after trauma, either by accident or by procedure.
Also, when you get injured, your wound may become purulent and pus may come out. Pus is the mark of white blood cells fighting bacteria to prevent them from entering the body. White blood cells work to prevent the transmission of diseases by eating bacteria that try to enter the body.
These are due to the natural healing power of humans. Water light injection also has the effect of promoting skin regeneration due to such natural healing power.
When a needle hole is made in the skin with an extra-fine needle, the natural healing power works to repair the needle hole, and a growth factor that activates cell activity is secreted to regenerate the skin .
Growth factors activate the function of fibroblasts that produce collagen, elastin, and hyaluronic acid, which are involved in skin firmness, elasticity, and moisturization, so the skin that has been reborn with increased elasticity has firmness, and fine wrinkles and pores open. You can expect improvement in sagging .
In the conventional manual injection method called Napage method, it is difficult to keep the injection range and injection amount of the drug uniform, so the injected drug may not be fully effective. In addition, the depth of the needle was not constant, so I sometimes felt a strong pain in some areas.
However, with the machine-based injection method, you can inject one shot at a time while applying suction pressure. By injecting while inhaling, you will be more aware of the stimulation of suction, which has the advantage of making it less likely that you will feel the pain of needle sticks . In addition, the needle length and injection amount can be set in detail, so the drug can be injected evenly.
The needle used for water light injection is a very thin needle of 31G (gauge). G (gauge) is a unit of the thickness of the injection needle, and the larger the number, the smaller the outer diameter of the injection needle. 16G-27G is mainly used in hospitals, and the thinner it is, the less pain you feel at the moment of stinging.
With water light injection, you can inject 5 to 9 needles in one shot with a very thin 31G needle . By setting the needle length, injection amount, skin suction pressure, and suction timing, you can inject a wide range at a uniform speed like a stamp, so it can be said that the procedure is faster than the manual injection that injects one by one. I will.
Machines used for water light injection have different characteristics depending on the manufacturer, and each has its own merits.
Dermashine Balance of Korea HOUNS is an automatic subcutaneous injection system that has spread from Korea, a beauty powerhouse.
Since one shot is injected simultaneously with nine needles, it is possible to perform a full face treatment in a short time of about 20 minutes. In addition, since it is possible to set the needle length, suction pressure, and suction timing, it is said that it is possible to accurately inject from a shallow layer of about 1 mm to a deeper layer, which is difficult to do manually.
In addition, since it can be injected vertically into the skin, the distance that the needle can enter is the shortest, and bleeding during the procedure and internal bleeding after the procedure are also reduced, so downtime is said to be short . Since the injection is performed while sucking the skin, the pain during the procedure is less likely to be felt by focusing on the suction.
The Dermashine Balance is a highly safe device approved by the Korean Ministry of Health, Labor and Welfare, Korea MFDS (Ministry of Food and Drug Safety).
The vital injector developed by Eunsung Global of Korea can inject with 5 needles per shot. Since the depth of needle sticking can be adjusted with the touch panel of the main unit instead of manually, there is no error in the depth.
The tip part has a structure that prevents the backflow of the drug and blood to be injected, which enables safe and reliable injection, and this backflow prevention structure is patented.
In addition, since the tip of the needle of the vital injector is square, the probability of missed shots and double hits is reduced compared to the round type. In addition, the suction and shot functions are separated, and suction pressure is always applied even before injection, so the drug is injected with the skin evenly attached to the needle, so the drug is accurately and uniformly deeply applied to the dermis layer. It is said that it can be injected .
Hyaluronic acid, which exists in the dermis layer in the skin, acts like a cushion that fills the gap between collagen and elastin and supports the flexibility and elasticity of the skin.
However, it is said that hyaluronic acid begins to lose its ability to produce with age, and as a result, the entire skin loses its freshness and elasticity, and wrinkles and sagging are likely to occur.
Hyaluronic acid has the ability to attract water as much as 200 times its own molecular weight, so hyaluronic acid that is widely and finely injected into the dermis layer by water light injection can be expected to have the effect of glossing the entire face by holding water. I will.
In addition, the injected hyaluronic acid holds water so that it fills the gaps between fibers such as collagen and elastin in the dermis layer, so it rejuvenates the skin, improves wrinkles and sagging, and leads to plump and elastic skin . I will.
Some hyaluronic acids used in aesthetic medicine are processed into a structure that is difficult to absorb by binding hyaluronic acids together in order to maintain their effects. This is called "crosslinking". The hardness of hyaluronic acid differs depending on the method of cross-linking, and the sustainability and intended use also change.
In addition to cross-linked products, there are also non-cross-linked products, and the hyaluronic acid mainly used for hydrophotoinjection is the latter non-cross-linked hyaluronic acid.
Cross-linked hyaluronic acid is a little hard and gel-like, so it is suitable for increasing volume such as raising the height, but non-cross-linked hyaluronic acid is a smooth and soft hyaluronic acid, so it is injected evenly over the entire face. Suitable for
Botulinum injection is a muscle relaxant containing type A botulinum toxin, which is a type of protein extracted from botulinum bacteria, as an active ingredient. Botulinum injection is a drug that can be expected to loosen facial muscles and make facial wrinkles less noticeable by suppressing the secretion of the neurotransmitter acetylcholine.
The well-known botulinum injection is a deep injection into the facial muscle layer to treat facial wrinkles by suppressing muscle contraction.
On the other hand, with water light injection, a very small amount of Clostridium botulinum injected into the dermis layer spreads throughout the face and weakens the function of only the surface fibers of the muscles, thereby tightening the skin and improving fine wrinkles while maintaining a natural facial expression. You can expect the effect.
One of the causes of conspicuous pores is a large amount of sebum secretion, but botulinum injection is said to have the effect of making the pores inconspicuous because it can suppress the secretion of sebum by suppressing the development of sebaceous glands . ..
It also works on the nerves of the sweat glands and suppresses sweat secretion, so you can expect the effect of making makeup less likely to collapse .
Glutathione is a substance in which three amino acids "glutamic acid + cysteine + glycine" are bound, and since it is originally present in most cells in the body, it is a safe component that does not easily cause an allergic reaction. Glutathione has a strong antioxidant effect.
When humans breathe, they take in oxygen into the body, but at the same time, active oxygen is generated inside the cells. Reactive oxygen is a substance that increases not only with respiration but also with aging, and is said to oxidize (age) cells and cause spots and wrinkles.
Glutathione is said to be able to prevent blemishes and wrinkles because it has an antioxidant effect that removes active oxygen generated inside cells .
In addition, glutathione is said to have a function of suppressing the deposition of melanin, which is a pigment formed by sunburn. By uniformly injecting glutathione into the epidermal layer where melanocytes, which are cells that produce melanin, are present by water light injection, it can be expected to prevent skin pigmentation.
The B vitamins are vitamins B1, B2, B6, B12, niacin, pantothenic acid, folic acid, and biotin, for a total of eight types. B vitamins have the function of supporting the metabolism of proteins that make skin, nails, hair, etc., and are important nutrients for normalizing skin metabolism, so if they are deficient, they are prone to rough skin.
By injecting B vitamins into the entire face by water light injection, it can be expected to have the effect of improving rough skin, acne, and acne scars . In particular, in the case of red acne and yellow acne caused by the growth of P. acnes due to a large amount of sebum, improvement can be expected due to the effect of suppressing the amount of sebum secreted by the B vitamins.
Vitamin C is one of the water-soluble vitamins and is also called ascorbic acid.
Collagen, which is necessary to give elasticity to the skin and maintain capillaries, has a spiral three-dimensional structure, and two types of amino acids, "pidroxypurine" and "hydroxydiline", are required to maintain the structure. Become.
Vitamin C is required to produce the two amino acids, and without vitamin C, the helical structure of collagen cannot be maintained, causing wrinkles and sagging. By incorporating Vitamin C, it supports the production of collagen, aiming for firm and elastic skin .
In addition, it inhibits the activity of the enzyme (tyrosinase) that works when melanin, which is the source of blemishes, is produced, and suppresses the production of melanin, so a whitening effect can be expected.
Vitamin C has an antioxidant effect, so it removes active oxygen and is said to suppress skin aging such as age spots and wrinkles .
Furthermore, by suppressing sebum secretion, it is said to be effective in improving acne because it has the effect of suppressing the growth of P. acnes that nourishes sebum and soothing inflammation .
It is thought that one of the causes of spots and wrinkles is an increase in active oxygen, but the antioxidant action has the function of removing active oxygen.
Pine spinner star is a pine bark extract that is said to have 50 times stronger antioxidant activity than vitamin E, and can be expected to suppress skin aging and prevent spots and wrinkles .
Resveratrol is a polyphenolic compound found in grapes, red wine, purple grape juice, peanuts, and certain berries. Resveratrol is said to have the function of normalizing the turnover cycle .
The rebirth of cells in the epidermis is called turnover. It is said that the ideal turnover cycle is about 28 days until the cells born in the epidermis layer are pushed up to the surface and finally become dirt and peel off.
If the turnover cycle is disturbed due to aging, lack of sleep, disorder of lifestyle such as eating habits, stress, etc., old keratinocytes will not peel off forever and will remain on the surface of the epidermis layer and widen the pores. Moisturizing ingredients such as intercellular lipids that fill the space between cells in the stratum corneum above the epidermis may be difficult to make.
In addition, when the skin becomes inflamed due to exposure to ultraviolet rays, degrading enzymes such as collagenase, elastase, and hyaluronidase are activated, and each of them decomposes collagen, elastin, and hyaluronic acid. If it is disassembled and the balance is lost, the skin will lose its moisture and elasticity, causing wrinkles and sagging.
Resveratrol has the effect of suppressing the activity of these degrading enzymes, and can be expected to have the effect of moisturizing the skin, maintaining elasticity, and preventing wrinkles .
Furthermore, it is said to have the effect of suppressing the growth of acne bacteria, which are involved in the onset and exacerbation of acne, and removing active oxygen with a strong antioxidant effect, thereby suppressing skin aging.
PRP treatment is a skin regeneration treatment born from regenerative medicine using PRP (plasma containing a large amount of platelets) extracted by centrifuging the blood collected from itself.
Platelets, which are abundant in PRP, are one of the cellular components contained in blood, and when a blood vessel is damaged, they collect in the wound and stick to and aggregate to close the wound and stop bleeding. At that time, platelets release growth factors. Growth factors are said to proliferate and activate cells to repair damaged tissue and support skin regeneration.
PRP taken from your own blood contains a number of growth factors. Growth factors activate collagen, hyaluronic acid, and elastin that maintain the firmness and elasticity of the skin by activating turnover, which is the renewal of the skin in the epidermis layer, and proliferating and activating fibroblasts in the dermis layer. Because it works, it can be expected to improve wrinkles, sagging pores, acne / acne scars, and crater skin .
Since it uses its own blood, there is less concern about side effects such as infectious diseases, allergies, and rejection reactions, and you can receive it with confidence.
By injecting PRP together with non-crosslinked hyaluronic acid, it promotes the regeneration of skin cells, and even with the effects of hyaluronic acid, it leads to firm, fresh and healthy skin.
Placenta is "placenta", and placenta handled by medical institutions is a placenta extract obtained by extracting the active ingredient from human placenta. We use only human placenta that has been confirmed to be free of infectious diseases such as hepatitis B and AIDS in human placenta born by normal delivery in Japan.
Placenta is rich in growth factors and proliferates and activates cells to promote skin cell regeneration. It is said that it increases collagen by activating fibroblasts and improves wrinkles and fine wrinkles such as nasolabial folds .
Furthermore, by promoting the turnover, which is the metabolism of the skin, and promoting the excretion of melanin, which causes blemishes, it improves blemishes, freckles, and dullness , leading to clear skin.
In addition to the three major nutrients such as proteins, lipids and sugars, it also contains abundant ingredients such as vitamins, minerals, nucleic acids and enzymes that are the raw materials for making skin cells.
Chloasma is thought to occur when cells called melanocytes are activated, and there is a substance called plasmin as a substance that promotes the activation of melanocytes.
Tranexamic acid, which has an antiplasmin effect, suppresses the activity of melanocytes and is thought to be effective in improving chloasma .
In addition, melanocytes produce melanin pigment, which is the source of dark spots and dullness, when exposed to ultraviolet rays. Tranexamic acid can suppress the generation of substances such as prostaglandins necessary for making melanin pigments, so it is also effective in preventing dark spots and dullness .
The recommended number of treatments varies depending on the purpose of treatment and the drug used , but if you want to increase the elasticity of the skin, first receive 2 to 3 treatments every 2 weeks for a turnover cycle. It is said that the effect of increasing the elasticity of the skin can be maintained for a longer period of time by preparing it and then performing it 5 times in total every 3 months to 6 months .
There are individual differences in the actual feeling of the effect, and it depends on the drug used, but in the case of hyaluronic acid, the effect is felt quickly because it holds water so as to fill the gaps between fibers such as collagen and elastin in the dermis layer. The effect appears about 1 week after the downtime, and lasts for about 1 to 3 months .
On average, other drugs begin to show their effects about 1 to 3 months after injection, and are said to last for 6 months to 1 year. Please consult your healthcare provider for more information, as the duration varies depending on the drug.
The fee varies depending on the medical institution, but it is about 50,000 to 100,000 yen for all faces . There are also differences depending on the type of drug used.
1) Medical examination
Since the effect of water light injection differs depending on the drug used, it is necessary to select the drug according to the worries of the recipient. Therefore, it is important to consult with the doctor about skin quality and wishes during pretreatment consultation and counseling.
2) Face wash
If sunscreen or foundation remains on the skin, it will be difficult for the drug to penetrate, so cleanse and wash your face thoroughly before the procedure.
After washing your face, apply an anesthetic cream. Wait about 30 minutes for the anesthesia to be effective. After confirming that the anesthesia is working, the beauty ingredients are evenly injected into the face like a stamp with a special machine set according to the patient's skin.
4) After treatment
If you wish, you can use a pack containing active ingredients such as growth factors.
It is said that you will feel almost no pain during the procedure because the procedure is performed after applying the anesthetic cream first, but there are individual differences in how you feel the pain. Due to surface anesthesia with anesthesia cream, it takes about 30 minutes until the pain becomes less noticeable.
There is basically no downtime. Although there are individual differences , if redness appears, it is often removed in 3 to 4 days, and you can cover it with makeup from the next day. The skin may become uneven 2 to 3 days after the procedure, but it will subside in 1 to 2 weeks .
Since it is a treatment that pierces the skin with a needle, bacteria may enter from the puncture site and cause infection in rare cases .
In addition, if you have had an allergic reaction after injecting hyaluronic acid in the past, or if you are allergic to anesthetics, please consult with your doctor at the time of counseling / examination.
Needleless water light injection is the mainstream in beauty treatment salons. There is no downtime because the beauty essence is infiltrated by wind pressure without using a needle, but the effect is low compared to medical institutions .
Water light injections for home use are also available, but because the same needle is used several times, it is difficult to keep them clean and the risk of infection is high .
Depending on the symptoms and requests of skin troubles, there are treatments that can be expected to have a higher skin-beautifying effect when used in combination with water light injection. Water light injection is a needle stick treatment, so if you want to perform other treatments on the same day, basically add another treatment before water light injection .
|IPL treatment||high frequency||Laser treatment||Hyphen||peeling|
|Pore (sagging pore)||△||○||○||△||○|
IPL treatment such as photo facial uses light called IPL (Intense Pulsed Light). IPL represents light with a wide range of wavelengths that cuts off harmful ultraviolet rays.
Wavelength represents the distance between peaks (valleys) of light fluctuation width. The shorter the wavelength, the more it affects the surface of the skin, and the longer the wavelength, the deeper the skin. For example, ultraviolet rays are also a type of light, but because of their short wavelength, they affect the surface of the skin and cause stains.
The IPL has multiple wavelengths, while the laser has only one wavelength, so it targets only one color. For example, a laser that targets black can destroy melanin, but not the hemoglobin that causes the reddish face.
On the other hand, IPL has multiple wavelengths of light and can work on different symptoms, so skin problems such as "blemishes", "freckles", "small wrinkles", "acne scars", "redness", and "tension" You can aim for improvement at the same time. Instead of irradiating spots and moles locally like a laser, it irradiates the entire face with a flash.
Combining IPL treatment before water light injection may accelerate the improvement of skin problems.
When the skin is irradiated with high frequencies, which are radio waves, the collagen fibers in the dermis layer contract due to the heat of the high frequencies, and a tightening effect can be expected.
In addition, new collagen proliferates in the process of repairing contracted collagen fibers. Therefore, not only the initial tightening effect, but also the growth of collagen over several months can be expected, and the effect of continuously improving the firmness of the skin can be expected. A synergistic effect can be expected to improve sagging by using water light injection and high-frequency treatment together.
Laser is one of the treatments that can be expected to have the effect of thinning spots, and the melanin pigment that causes spots can be destroyed by the light of the laser . The melanin pigment destroyed by the laser is preyed on by phagocytic cells called macrophages, which have the function of eating and digesting foreign substances such as bacteria that have invaded the body, and are decomposed and digested.
In addition, melanin that has not been phagocytosed by macrophages is pushed out to the epidermis by the action of turnover, becoming keratin and peeling off. By promoting turnover with water light injection, synergistic effect can be expected for spots by promoting the excretion of melanin that was not phagocytosed by macrophages .
The official name of HIFU is High Intensity Focused Ultrasound, and the abbreviation for HIFU is called HIFU.
By concentrating ultrasonic waves on the SMAS fascia, which is the membrane between the fat layer and the fascia, and tightening the sagging fascia with heat, it improves the sagging of the skin without burning the surface skin. This is the treatment you are aiming for.
By combining HIFU before water light injection, a synergistic effect can be expected to improve wrinkles and sagging.
Chemical peeling is a procedure in which an acidic drug is applied to the surface of the skin to loosen the bonds of the stratum corneum at the top of the epidermis layer with disturbed turnover, thereby naturally removing old keratin .
Since the penetration of the drug used in water light injection is higher when the old keratin is removed, a synergistic effect can be expected by incorporating chemical peeling before water light injection .
Dermapen 4 is an example of a cosmetological device that uses multiple needles. Dermapen 4 is a pen-type device with 16 thin needles attached to the tip.
It is a treatment that aims to regenerate skin cells by intentionally making fine needle holes in the skin by applying high-speed vibration to the skin and utilizing the natural healing power to repair the needle holes .
At the same time as or after the treatment of Dermapen 4, by applying a drug containing beauty ingredients with fine needle holes in the skin, it penetrates deep into the skin and enhances the effect of the drug.
|Water light injection||Dermapen 4|
|depth||1.0-2.0 mm||0.2 mm to 3.0 mm|
|pain||Using anesthesia, almost no pain||Use anesthesia to reduce pain|
|downtime||3-5 days||3-5 days|
|Single injection volume||Accurate for automatic||There is a difference in the amount because it is applied before and after the needle is stabbed.|
|Small parts||Accurate injection is difficult in areas where suction is difficult, such as the nose||Can be used for small areas such as the nose and eyes|
|Purpose||Gives firmness and elasticity by injecting the drug directly into the dermis layer||Increases collagen by repair ability by making wounds|
In water light injection, the drug is injected directly into the epidermis layer to the dermis layer of the skin using an injection needle to deliver beauty ingredients, but Dermapen 4 makes a needle hole in the skin by piercing the needle and repairs the needle hole. It is a treatment that uses the natural healing power to increase collagen and regenerate skin cells .
Since the expected effects of water-light injection differ depending on the action of the drug used, it is recommended to check the website etc. before consulting whether the drug you want to use is available at a medical institution.
In addition, since water light injection is a procedure that pierces the skin with a needle, there is a risk of bacterial infection if hygiene is not managed . To prevent infection, it is safe to choose a medical institution that you can trust in hygiene management .
