Hello. I'm Dr. Jung Huh, Chief Director of Ruby Dermatology Clinic, where we focus on the skin's naturally healthy structure and anatomically layered treatment.

"My double chin and deep cheek fat are so thick that they hide my jawline, but I hesitate because conventional laser lifting causes intense burning heat and pain. Is there a treatment that reduces just the fat and lifts the skin without bruising or swelling?"

This is a question I often hear from people who hesitate to get a lifting treatment because they worry about pain and downtime.

You need to move beyond the surface heat and deep, aching pain that conventional radiofrequency (RF) and high-intensity focused ultrasound (HIFU) devices cause as they deliver heat through the epidermis. ONDA lifting, which uses special microwave energy to minimize molecular vibration in the epidermis while focusing energy on the subcutaneous fat and dermal layers, has become an efficient alternative for fat reduction and tightening.

💡 [3-Point Summary]

How ONDA lifting works: Special 2.45 GHz microwave energy passes straight through the epidermis to the subcutaneous fat and dermal layers without conduction loss, inducing fat cell death (apoptosis) and collagen remodeling.

Epidermal protection and a low-pain mechanism: A contact compact cooling system (Coolwaves™) keeps the skin surface cool and protected, so there is little pain, burning, bruising, swelling or other downtime during treatment.

Customized handpieces: The 3 mm handpiece tightens the dermis and improves fine lines, while the 7 mm handpiece selectively destroys the thick fat layers of the double chin and deep cheeks to create a sleek V-line.

A. The Anatomical Energy Delivery Mechanism of ONDA Microwave

ONDA lifting differs from conventional heat-delivery methods in the very medium that the energy reacts with.

2.45 GHz microwaves and fat cell selectivity:

The 2.45 GHz frequency has the physical property of being absorbed by fat cells in the subcutaneous layer rather than by water molecules in the epidermis, with about 80% or more of the energy concentrated in the adipocytes; as a result, no energy is wasted as unnecessary heat in the epidermis, and it reaches its destination, the fat layer, intact.

Fat cell death (apoptosis) and immediate collagen contraction:

Thermal stimulation of the fat cell membrane induces natural cell death, and the cells are then cleared from the body through the lymphatic vessels. At the same time, it immediately contracts aged collagen fibers in the dermis and stimulates new collagen production, so the skin stays snug rather than sagging where the fat has been reduced.

B. Is ONDA Lifting Right for Me? Who It's Recommended For

1) Strongly recommended for:

People with a double chin, a thick jawline or deep cheek fat that makes the facial contour look dull

People who are afraid of the pain, burning heat and bruising that come with conventional lifting treatments such as Ulthera or INMODE

People who need to return to daily life and important events right after treatment, without bruising or swelling

C. Conventional Radiofrequency (RF) / Ultrasound (HIFU) vs. ONDA

D. Treatment Schedule and Duration of Results

Recommended schedule: Depending on the amount of accumulated fat and the degree of laxity, we recommend 3 sessions at 3–4 week intervals.

Duration of results: Destroyed fat cells are eliminated from the body and permanently reduced, and the elasticity from remodeled collagen is maintained for a year or more.

E. 🔥 Completing a Sleek Contour: the 'ONDA Dual Fit' Synergy Combination

ONDA Lifting + Jawline Botox:

ONDA lifting destroys the double-chin fat, while Botox reduces an overdeveloped masseter muscle (square jaw), completing a smooth, slim jawline contour.

ONDA Lifting + Juvelook / Skin Booster:

After smoothly sculpting the deep cheek and double-chin fat, placing Juvelook in the dermis gives the best firming synergy, so the face looks smaller while the skin surface stays snug and taut.

F. Dr. Jung Huh's Practical Know-How & Clinical Insights

ONDA lifting is not simply a matter of pressing and gliding an energy device over the skin. It is a precise thermal-calorie calculation that distributes the number of joules and the depth handpiece differently according to fat thickness and dermal density in each area.

Before treatment, I use a precision ultrasound diagnostic device to measure each patient's double-chin fat thickness and fascia position in real time. In thick areas of fat, I concentrate energy with the 7 mm handpiece to induce fat destruction, and along the jawline and sides of the cheeks I switch to the 3 mm handpiece to make the skin snug. This approach, which I call 'Custom Dual Depth Mapping,' creates a smooth, well-defined V-line with minimal pain and few side effects.

📌 [Final Notes] Pre- and Post-Treatment Precautions

Drink plenty of water: Drink at least 1.5 L of water a day so the destroyed fat cells and waste products are cleared quickly through lymphatic circulation.

Gentle lymphatic massage and warm care: Wash your face with lukewarm water after treatment and gently massage along the jawline to help waste clear smoothly.

Sun protection and avoiding irritation: Apply sunscreen to support skin regeneration, and avoid heavy drinking and vigorous exercise on the day of treatment.
