beauty treatment

As the skin ages, changes in pigmentation, such as age spots and dullness, as well as changes in shape and elasticity, such as sagging and wrinkles, occur. Medically based treatments are now available to address these age-related skin changes.
In our department,① Hair removal (laser treatment),② Skin beautifying treatment (laser treatment, phototherapy, mesoporation, chemical peeling)We strive to provide safe treatment tailored to each individual, taking into consideration social restrictions, etc.

① Hair removal

Medical hair removal device diode laser VECTUS™ LASER

How body hair works
ダイオードレーザーBody hair is divided into a hair shaft above the skin and a hair root below the skin, and the tissue surrounding the hair is called a hair follicle. The hair bulb is the swollen part of the hair follicle and contains a hair papilla that nourishes the hair matrix cells. Hair is produced and grows when the hair matrix cells in the hair bulb undergo cell division and keratinization.
Hair growth has a cycle that is divided into three phases: growth, catagen, and resting.
What is Diode Laser Hair Removal?
Diode lasers are lasers that are generated using semiconductors, and their wavelength of 800 nm, which reacts to black melanin pigment, is used for hair removal.
When the diode laser is irradiated, heat is transmitted to the black hair root, destroying the hair matrix cells in the hair root, as well as the hair follicle, hair papilla, and sebaceous gland that are adjacent to the hair root, resulting in hair removal.
However, as mentioned above, hair growth has a cycle, and hair follicles in the resting phase do not contain black melanin, so hair removal is not possible. Only hair in the growth phase can respond to laser irradiation and achieve hair removal, so several irradiations according to the hair growth cycle are required.
VECTUS™ Features
VECTUS™Compared to conventional medical laser hair removal, Cynosure's Vectus boasts a high hair removal effect regardless of hair color, thickness, or skin color. In addition, it has been approved by the FDA (Food and Drug Administration: U.S. Department of Health and Human Services) for its hair removal effect.http://www.accessdata.fda.gov/cdrh_docs/pdf12/k120622.pdf) and has been approved.

The use of a large, thick sapphire allows for uniform energy transmission across the treatment surface, as shown in the diagram below (the left is a conventional laser, the right is Vectus). Furthermore, the contact cooling function cools the skin surface as the laser is applied, minimizing the risk of burns and reducing pain during treatment.

In addition, Skintel™ (melanin reader) diagnoses skin tone and predicts the optimal energy value, enabling effective hair removal while preventing complications such as burns.

CO2 (carbon dioxide) laser AccuPulse

炭酸ガスレーザーThe 10,600nm wavelength emitted by the carbon dioxide laser is well absorbed by water, so it heats and vaporizes tissue containing water, thereby removing the tissue.This means that it is possible to treat raised lesions that are not colored, regardless of the color of the lesion.

Conventional carbon dioxide lasers cause thermal damage of over 200 microns to the surrounding tissue, resulting in the formation of a carbonized layer, but Lumenis's "AcuPulse" causes extremely little thermal damage to the surrounding tissue, at less than 50 microns, resulting in less postoperative inflammation and a lower risk of pigmentation.

皮膚断面図
1. Scan function included
Computer control makes it possible to achieve extremely thin and uniform evaporation.
To prevent pain during treatment, the affected area is cooled or locally anesthetized before laser treatment.
2. With fractional function
フラクショナル照射時This function splits the laser light into tiny dots and irradiates the skin, creating numerous cylindrical microscopic holes at a certain density, causing the skin to evaporate. There are two types of treatments: shallow abrasion with a 1.3mm diameter spot to evaporate the surface of the skin in dots, and deep abrasion with a very small 0.12mm diameter spot to evaporate deep into the skin (2), and these can be combined for treatment.

Target diseases
Elevated lesions such as nevus cytoides (mole), common warts, and seborrheic keratosis
When using fractional function: pores, fine lines, dullness, acne scars

CUTERA XEO series beauty equipment

This device is FDA approved as a cosmetic medical treatment device.
(http://www.accessdata.fda.gov/cdrh_docs/pdf13/K132185.pdf).
It can be equipped with several types of skin treatment handpieces, allowing you to treat a variety of skin problems by using different handpieces.

Handpiece Type
  1. Light therapy device (Limelight)
  2. Phototherapy device (AccuChip)
  3. Near-infrared therapy device (Titan)
  4. Long pulse Nd:YAG laser
  5. Er:YSGG laser (Pearl)
1. Light therapy device (Limelight)
ライムライトBy emitting light with wavelengths of 520 to 1100 nm, this device is effective for lesions that are difficult to treat with conventional phototherapy devices. The irradiation promotes epidermal turnover and excretes melanin, improving dullness, age spots, and freckles. It also acts on dilated blood vessels to improve telangiectasia, and the thermal effect on fibroblasts and dermal collagen improves skin texture and pores.
2. Phototherapy device (AccuChip)
By irradiating shorter wavelengths (500-635nm) that are highly absorbed by melanin and hemoglobin, it is more effective than Limelight for treating pigmented lesions and telangiectasias.
3. Near-infrared therapy device (Titan)
Light with a wavelength of 1100 to 1800 nm, which is absorbed by water, is irradiated to heat the inside of the dermis, promoting collagen contraction and growth, thereby improving wrinkles and sagging.
4. Long-pulse Nd:YAG laser
It emits a 1064nm wavelength that is absorbed by both melanin and hemoglobin, reducing redness and improving visible capillaries.
In addition, by irradiating the air away from the skin and heating the papillary dermis, it promotes collagen production and improves skin texture and firmness (Genesis).
5. Er:YSGG laser (Pearl)
Laser treatment to evaporate keratin (skin resurfacing) has been performed in the West for some time, but there was a risk of pigmentation in Asians. Pearl is a laser that significantly reduces this risk.
The laser, emitted from a YSGG (Yyottrium Scandium Gallium Garnet) crystal, has a wavelength of 2790 nm. The epidermis is stimulated to evaporate the stratum corneum, promoting the regeneration of new skin. The dermis is stimulated to shrink, regenerate, and restructure due to thermal denaturation of collagen, improving skin quality.

V-beam

This is a 595nm dye laser with a new function that allows adjustment of the laser pulse width (irradiation time).It is selectively absorbed by hemoglobin in the blood, so in lesions where capillaries have aggregated, the hemoglobin absorbs the laser energy and converts it into heat, which causes thermal destruction of the inner walls of the blood vessels, blocking the blood vessels and eliminating the red color.
Equipped with a function called a dynamic cooling device, it blows ice air just before laser irradiation, making it possible to irradiate the hemangioma while protecting the skin, thereby reducing the risk of burns.
It also stimulates fibroblasts, which is effective against fine wrinkles.
Insurance covers vascular lesions (hemangiomas and telangiectasias).

Mesoactis - Skin Electroporation

メソアクティスFor a substance to penetrate the skin, it must pass through the stratum corneum, the outermost layer of the skin. However, the stratum corneum has a barrier function that prevents substances from easily penetrating through the skin surface.
In this method, a high-voltage current is applied to the skin for a short period of time to create temporary holes that allow substances to pass through (electroporation), and a low-voltage current is then applied through these holes, allowing the drug to be introduced painlessly, regardless of the drug's charge or molecular size.
It is effective in improving age spots, wrinkles, skin texture, dry skin, post-inflammatory hyperpigmentation, and melasma.

Chemical peeling

Chemical peeling is a treatment that uses acid to remove dead skin cells and promote skin regeneration by stimulating cell turnover.
It helps improve skin texture, acne, and blemishes.

Treatment flow

After making a reservation and receiving the consultation, you will first undergo counseling (initial consultation).
A specialist will provide a detailed explanation of the treatment, including any risks, and will only begin treatment after obtaining fully informed consent.
If a malignant disease is suspected, a microscopic tissue examination is required, so surgery rather than laser treatment is indicated and the treatment is covered by insurance.
