❄️ The Secret of the 'Cooling System' That Defies the Common Sense of Lifting

Natural Beauty Bellevue Clinic

Hello, this is Bellevue Clinic, where we explore the scientific essence of lifting. The first questions people considering lifting procedures usually ask are two things: “How much lifting does it provide?” and “How painful is it?” In fact, these two questions have always been conflicting challenges in the history of lifting devices. That is because when energy is delivered powerfully, the effect is good but the pain is severe, and when energy is lowered to reduce pain, the effect is weakened.

But the recently hottest topic in the lifting market, ONDA, completely goes against this formula. While the procedure itself feels “cold and refreshing,” the result you see in the mirror afterward is a surprisingly tighter jawline. These days, ONDA is the device most recommended for people with fuller or puffier faces, both for the face and body. Today, I’ll explain the core principle behind it: the relationship between “Contact Cooling” and “Microwave.”

  1. ONDA’s Cooling System and What Makes It Special

Many people think of the cooling system attached to lifting devices as something like an “ice pack” that simply soothes the hot pain generated during treatment. Of course, pain relief is one purpose, but in ONDA lifting, cooling is on a different level because it acts as both a guide for energy delivery and a pathway.

1> Selective Energy Penetration

The 2.45GHz microwave used by ONDA has a unique property. It passes through low-temperature tissue without resistance and generates heat only in the deep fat layer where energy is concentrated. To put it simply, this is due to the physical properties of microwaves called “dielectric loss” and “impedance matching.”

(Impedance Matching)

The epidermis, the outermost layer of skin, has a lot of moisture and therefore high conductivity. Ordinary radiofrequency energy reacts immediately when it encounters this moisture and generates heat. But when ONDA’s cooling system lowers the temperature of the epidermis, the electrical resistance (impedance) of the epidermal tissue changes. Cooled epidermis = like a transparent window!!! From the microwave’s point of view, the cooled epidermis no longer feels like something to react to, but rather like a passageway. As resistance decreases, energy does not bounce off the surface or dissipate as heat; it passes through as is.

(Reduced Dielectric Loss)

The way microwaves generate heat is by vibrating water molecules. But when the epidermis is strongly cooled, the energy of the water molecules in the epidermis drops and their activity decreases. It’s the same principle as ice not melting easily in a microwave. You may have seen frozen meat that is rock solid on the outside but cooked on the inside in a microwave. In the same way, water molecules in cooled tissue do not react violently to microwaves. Thanks to this, the energy passes over the cold surface and only then reaches the fat layer, which is relatively warmer and absorbs energy well, where it finally generates strong frictional heat.

Fat has a low moisture content and low conductivity. Paradoxically, microwaves penetrate more deeply and concentrate energy better in tissue with moderate resistance, such as fat, than in tissue with more water. Let’s summarize it as cooled epidermis (low resistance) → fat layer (appropriate resistance). Thanks to cooling, the epidermis becomes a “no-resistance pass,” and only when the energy reaches the target fat pocket does dielectric heating begin.

2> More Than Just Epidermal Protection

ONDA’s handpiece keeps the skin surface cool at around 15°C throughout the procedure. By cooling the outer skin this way, microwave energy is not wasted in the epidermis and instead passes through smoothly, like going through a transparent window, directly reaching the fat layer and the lower dermis we are targeting.

  1. “Cold Outside, Hot Inside”: Hot Energy Hidden Beneath a Cool Surface

Clients receiving ONDA treatment often say it feels like “rubbing an ice pack.” But beneath that cold sensation, strong heat energy above 50°C is being generated deep within the skin. This is ONDA’s unique method of “intelligent energy delivery.”

1> Overcoming Moisture Resistance

Conventional radiofrequency (RF) often meets resistance in the moisture-rich epidermal layer, making heat spread outward more easily. In contrast, ONDA’s microwaves, with the help of the cooling system, pass through the moisture-rich epidermis comfortably and then concentrate energy in the “fat pockets” where fat cells are densely packed.

2> High-Density Energy Accumulation

Because the energy is not lost on the surface and is accurately delivered to the target area, the tissue-contraction remodeling effect is maximized while the discomfort felt by the patient is minimized. A cool outside and hot inside environment is the core technical strength of ONDA lifting.

  1. Why Does It Feel Different from Other Devices? (Comparison with Titanium and Thermage)

One of the questions clients often ask is, “Titanium and Thermage also have cooling—what’s the difference?” Yes, let’s clearly organize what makes them different.

Difference from TitaniumSoprano Titanium also has excellent sapphire cooling, but it mainly works to suppress pain caused when laser light reacts with melanin pigment.
Difference from ThermageThermage sprays cooling gas to disrupt the pain signals sent to the brain.
ONDA’s distinctionONDA’s cooling is an engineering design that optimizes the very “pathway” through which energy enters. Its purpose is to make the treatment less painful while creating an environment where energy can reach the deep tissue as quickly and safely as possible.

  1. Bellevue’s Focus: ONDA’s “Safety Sensor”

ONDA’s smart design can also be seen in more than just cooling. Its synergy comes from a “contact detection automatic sensor.” In most devices, if the handpiece lifts even slightly off the skin, the energy may remain on the surface and create a burn risk. But ONDA is equipped with an intelligent sensor that delivers energy only when it is in firm contact with the skin and stops immediately when contact is lost. Through Return Electrode technology, it tightly controls the energy so it does not leak sideways, allowing the energy to concentrate only on the targeted area.

  1. For These People, ONDA Lifting Is the Best Choice

★ For those who are afraid of pain

If you wanted lifting but could not try it because of the pain from Ulthera or Thermage, ONDA opens a new world.

★ For those who need definition of a double chin and deep cheek fat

Microwaves selectively target fat cells and smoothly refine unnecessary volume.

★ For those who value returning to daily life immediately after treatment

Thanks to the cooling system, there is almost no redness or swelling on the skin surface, so it is fine to schedule important appointments right after the procedure.

It is important how strongly the energy is delivered. But even more important is how accurately that energy is delivered deep inside without loss. ONDA lifting is a device that awakens the elasticity sleeping deep within your skin through a smart cooling guide. Bellevue Clinic’s medical staff fully understand ONDA’s mechanism and will accurately target the areas that need energy based on your facial shape and fat distribution. Not painful, yet with clear results. Experience the science of ONDA lifting for yourself at Bellevue.
