Onda Laser: Microwave Principle Simultaneously Addressing Fat and Sagging



Onda Laser is a treatment that uses microwave (2.45GHz) energy to directly destroy fat cells and simultaneously stimulate collagen in the dermal layer to improve sagging. It is distinguished from existing lifting treatments in that it addresses two goals – fat reduction and lifting – with a single device.







Microwave Principle — Why it Addresses Fat and Dermal Layer Simultaneously



The core technology of Onda Laser is 'Coolwaves'. This method selectively delivers microwave energy deep into the subcutaneous fat layer and dermal layer while cooling the skin surface. This structure minimizes epidermal damage and concentrates thermal energy on the target tissue.



Fat cells absorb microwave energy approximately 2-3 times better than collagen tissue or surrounding blood vessels. Thanks to this selectivity, heat is concentrated in fat cells even with the same energy delivery, damaging the fat cell membrane and inducing fat cell death (apoptosis). The dead fat cells are then processed by the body's macrophages and naturally expelled.







Simultaneously, thermal stimulation applied to collagen fibers within the dermis induces collagen contraction and neocollagenesis. Because these two processes occur together during a single treatment, Onda Laser offers a dual effect of 'fat decomposition + improved skin elasticity'. Its depth of action and mechanism differ from simple RF lifting, which focuses on heating the skin surface.







Indications — Onda Laser is Suitable for These Concerns



Onda Laser is suitable for the following situations: typically, when there is noticeable fat volume, such as a double chin or submental fat, accompanied by sagging due to reduced skin elasticity, or when facial contours are compromised by sagging fat below the cheeks. Even if there isn't a lot of fat, stimulating dermal collagen alone can be an indication for treatment.



The ability to directly access the fat layer without incision and the possibility of returning to daily life immediately after treatment are key reasons for choosing Onda Laser. Unlike surgical fat removal, the recovery period is short, and among non-incisional lifting treatments, the energy depth reaching the fat layer is relatively deep.







Number of Treatments and Cycle



The effects of Onda Laser become more pronounced when approached as cumulative treatments rather than a single session. Generally, 3 to 5 sessions are performed at intervals of 4 to 6 weeks, with the number of sessions adjusted based on the individual's fat volume and degree of sagging. Since it takes several weeks for dead fat to be expelled from the body, it is more accurate to evaluate results 4 to 8 weeks after treatment rather than immediately after.



Collagen regeneration effects continue for up to 3 months after treatment. Therefore, it is appropriate to evaluate the final results 3 months after the last treatment, and this point should be the basis for deciding on additional treatments.







Pain and Downtime



During Onda Laser treatment, you may experience warmth and a slight tingling sensation. While it can be performed without anesthetic cream, discomfort increases with higher energy output. Temporary redness and warmth after the treatment subside within a few hours, and most people can return to daily life on the same day. Severe bruising or swelling is rare, so downtime is short.



For 1-2 days after the treatment, it is recommended to strictly avoid sun exposure and refrain from activities that raise facial temperature, such as saunas, strenuous exercise, or alcohol consumption. Adequate hydration helps with fat cell expulsion.







Frequently Asked Questions



Q. Is the primary goal of Onda Laser fat removal or lifting?


A. Onda Laser targets both fat cell death and collagen regeneration through its microwave principle. If you have both fat volume and sagging, you can expect both effects simultaneously, and even with less fat, it can be used alone for dermal stimulation. At Kkeut Oriental Medicine Clinic, we confirm the emphasis on these two goals during consultation before designing the treatment plan.



Q. When do Onda Laser effects appear?


A. It takes several weeks for dead fat to be expelled from the body, and collagen regeneration continues for 3 months. The final results of Onda Laser are accurately evaluated 3 months after the last treatment.



Q. Is Onda Laser treatment very painful?


A. The sensation of warmth is manageable even without anesthesia. Kkeut Oriental Medicine Clinic manages pain by initially raising deep tissue temperature with high output and slow movement, then switching to standard output and fast movement. This method reduces discomfort while maintaining effectiveness.



Q. How many Onda Laser sessions are needed to see results?


A. Collagen stimulation and fat cell death begin even with a single treatment. However, significant changes become more pronounced after 3-5 cumulative treatments. A regular, cumulative approach is more effective than a single session.







Kkeut Oriental Medicine Clinic's Commitment



Kkeut Oriental Medicine Clinic always performs Onda Laser treatment design while the patient is in a seated position. Designing in a lying position can alter the position of the skin and fat, risking energy delivery to hollowed cheek areas. Seated design accurately identifies the position of sagging fat in a real-life standing or sitting posture to target treatment, and it is Kkeut Oriental Medicine Clinic's principle to prevent side effects like hollowed cheeks.



Kkeut Oriental Medicine Clinic applies a two-stage operation method during treatment: first delivering sufficient thermal energy to the deep layers with high output and slow movement speed, then switching to standard output and fast movement. This method is Kkeut Oriental Medicine Clinic's treatment know-how for minimizing pain while maximizing energy delivery efficiency.



Kkeut Oriental Medicine Clinic provides a lifting card after Onda Laser treatment. It records and shares the treated area, concentrated target areas, and energy settings with the patient. This integrated care system ensures consistency, allowing subsequent treatments to follow the same standards regardless of which branch is visited.
