Thank you for visiting the website of Jeisys Medical Japan.
A single pimple can bother a person. A large pigmented nevus in a noticeable facial area can be even more depressing. This is especially true for young women.
For such patients, many clinics have adopted the carbon dioxide gas laser (CO2) Edge ONE.
Dr. Aya Yakabe, Director of the Miyabi Clinic, will introduce cases using Edge ONE that she performs on a daily basis.

Principles and features of carbon dioxide laser (0:44-)

CO2 laser is a gaseous laser with 10,600 nm wavelength. Thermal energy is generated in the moisture in the skin, shaving off targeted lesion tissue by heat as the moisture evaporates.
A benefit of treatment with CO2 laser is that it is surgical in nature, with no use of a scalpel. Only the lesion tissue can be removed without damaging the skin.
Short irradiation exerts minor thermal coagulation/thermal denaturation effect on the tissue. Longer, stronger effects exerted.
This adjustability allows Edge ONE to perform sensitive procedures.
Edge ONE is equipped with Surgical Mode and Fractional Mode. I ‘ll introduce here the treatment using the Surgical Mode.

Actual applications of Edge ONE(03:40~)

The use of a lower frequency setting is preferable for patients who are not familiar with it.
Cooling or local anesthesia is required before irradiation. Simultaneous use of an inhaler is advisable as viruses and bacteria could remain in the smoke produced during evaporation.

Lesions in the periocular area and nasal wings requiring caution can also be removed without disrupting the line.

The CO2 laser can perform delicate transpiration in cases where surgery would leave scars. Mastering the technique with the CO2 laser will give you a wider treatment options and a new tool in your arsenal.

Summary|Advantages of Edge ONE Surgical Mode/Ultra Mode(07:00~)

Edge ONE’s Surgical/Ultra Mode can change the pulse width, preventing such problems as hyperpigmentation.
As the frequency is changeable, we use high frequency for transpiration, then lower it for a more delicate procedure as a finishing touch. Because of this feature, this is the machine we use most often.
When treatment is successful, patients are eager to share their joy with those around them. In this way, we can expect to attract more patients.
