'Is swelling after Onda Lifting

not a side effect?'

Many people ask whether the swelling that occurs after Onda Lifting is a side effect.

Since your skin will inevitably be different from its usual state, feeling anxious is only natural.

Today, we will look at the principles of Onda Lifting and explain in detail why swelling after the procedure is not a side effect but a normal recovery process, as well as in what situations it may last longer than the usual period.

Onda Lifting is a procedure that selectively concentrates microwave energy in the dermis or subcutaneous fat layer.

Microwave energy is the same type of energy used in microwaves. Because it has a long wavelength and low frequency, it passes through the surface and efficiently delivers heat only to the required depth.

Onda Lifting uses two handpieces.

The 3mm handpiece improves elasticity through collagen regeneration in the dermis, while the 7mm handpiece reaches the deeper subcutaneous fat layer and breaks down fat cells.

It has a built-in cooling system (Coolwaves™) and real-time temperature sensors, so it can effectively deliver energy to the target layer while protecting the skin’s surface.

Onda Lifting Why Does Swelling Occur?

Swelling after Onda Lifting is a normal reaction that occurs as the skin tissue responds to heat.

It can be said to be a natural physiological phenomenon that appears during the process in which the skin tissue recovers and regenerates on its own.

To explain more specifically, when microwave energy delivers heat to the dermis or subcutaneous fat layer, the process of collagen fibers contracting and fat cells breaking down begins.

At this time, blood flow increases, cells move, and lymph fluid temporarily stagnates in order to repair the microscopic damage in the tissue.

Swelling is the response that occurs when moisture in the skin tissue temporarily increases during this recovery process.

Even if the cooling system works to protect the skin’s surface, sufficient heat is still needed in the deeper layers for the procedure’s effect, so this swelling can actually be considered a normal result.

Onda Lifting Swelling How Long Does Swelling Usually Last?

In most cases, swelling naturally goes away within 1 to 3 days.

Of course, depending on individual skin sensitivity, the treatment area, and the intensity of the procedure, slight swelling may remain for up to about a week.

I saw an online review saying that the swelling lasted more than 2 weeks and they were worried about it. Of course, cases like that are rare.

In such cases, it is usually due to constitutional factors, or because the skin is very thin and sensitive.

There are also variables related to the procedure itself, and if the energy intensity was set too high or energy was delivered multiple times to the same area (overlapping exposure), the tissue reaction may be greater.

Aftercare can also affect how long swelling lasts. Drinking alcohol, smoking, and exposure to high-temperature environments such as saunas or Korean steam rooms (jjimjilbang) can all contribute to prolonged swelling.

However, there are cases that require observation and caution.

If the swelling gradually gets worse, pain increases, or only one side becomes unevenly swollen, infection or an excessive inflammatory response cannot be ruled out.

In such cases, it is best to contact the clinic where you received the procedure and have your condition checked.

Swelling after Onda Lifting is not a side effect, but a normal signal that appears as the skin regenerates and remodels itself.

Trying to force the swelling down with ice or washing your face with cold water may actually reduce the procedure’s effect, so it is better to let it settle naturally and simply follow the aftercare instructions you were given.

What I shared today is something you should actually know in advance through the medical staff before getting the procedure, so while consulting, it would be good to check whether they explain these things clearly.
