CO2 laser plays a very important role in aesthetic medicine. Its high absorption rate and diverse irradiation modes make it effective in treating various skin diseases. In this article, Dr. Yoko Yoshioka of Takanashi Clinic, Medical Corporation Yokokai, explains in detail the features, treatment techniques, and advantages EdgeONE CO2 laser, which she has been using for 12 years. Dr. Yoshioka says that the mole removal procedure she performs using EdgeONE is constantly booked, even though there is currently a two to three month waiting list. What is the secret behind its fame? Don’t miss Dr. Yoshioka’s explanation of the appeal of EdgeONE.

CO2 Laser EdgeONE Surgical Mode Features
EdgeONE Surgical Mode is a versatile laser with a high output power of 30W and five irradiation modes. This mode has high oscillation efficiency and can accommodate various pulse widths. In particular, the laser idling technology provides a minimally invasive yet highly effective result. Postoperative downtime is short and patient satisfaction is high. It is also cost-effective because it requires no consumables and has minimal breakdowns.
Treatment Techniques and Points to Note
Treatment with CO2 laser requires a precise technique. In mole treatment, first approach the area with Incision Mode, then use Ultra Pulse Mode to transpire the remaining pigment. Moving the hand quickly and not stopping at the same spot is important. Care must also be taken in how the local anesthesia is administered. Injection volume and pain can be reduced by following the travel of the sensory nerves. Postoperative moist therapy is necessary to prevent crusting.
Is a scanner function required for CO2 laser?
Lasers with a scanner can irradiate a wide area evenly, allowing for efficient treatment. However, types with lower continuous wave output should be used with caution because it increases the risk of thermal damage and scarring. Scanners should not be used when there are differences in thickness of the same lesion, as additional irradiation is required. When irradiating large areas, it is important to be aware of the risk of PIH and scarring.
Comparison with the Punch Excision Technique
The punch excision technique is a simple technique and causes little damage to the surrounding tissue. However, it has the downside of contraction due to the loss of the entire dermal layer. CO2 laser, in contrast, has less complete loss and less contraction, so it is possible to leave the dermis intact and aim for flattening. Dr. Yoshioka does not perform the punch excision but chooses CO2 laser to reduce the patient’s burden and optimize treatment results.
Fractional Mode Features and Treatments
Acne scars
Pigment spots
fine lines and wrinkles due to dryness
Scarring
Fractional Mode is characterized by causing tissue changes in a minute area and short downtime. It has a short downtime of about one week and is available in three beam sizes and five beam patterns, including Stacking Mode that allows for deeper transpiration. Indicated diseases include melasma, acne scars, wrinkles, and sagging skin; irradiation after the application of water enhances the effect. It has also been shown to be effective in the treatment of minor scarring.
Advantages and Disadvantages of CO2 Laser, and Non-applicable Diseases
The advantages of CO2 laser are minimally invasive and short postoperative downtime. Patient satisfaction is high, and it is cost-effective with no need for consumables. On the down side, it is generally not indicated for malignant tumors or blue nevus with pigmentation in the dermis. However, Dr. Yoshioka uses it effectively for intradermal hyperpigmentation through her technique and thorough postoperative care. With proper use and care, CO2 lasers can be a very effective treatment options.
Summary
CO2 laser is a very useful tool with its high efficacy and minimally invasive nature. In particular, EdgeONE offers a wide range of treatments in Surgical Mode and Fractional Mode. For clinics considering introducing it, it is a cost-effective option because it requires no consumables, has low running costs, and offers a wide variety of treatment options. We encourage you to consider introducing EdgeONE CO2 laser to improve patient satisfaction and achieve more effective treatments.
