Painless Onda laser lifting, what does Onda KJ mean?

Even though we’re all getting older at the same pace, there are friends who take good care of themselves. When you meet someone who looks much younger than you, it naturally makes you want to start taking care of yourself too. Stop just envying your friends’ firm skin and jawline. Now it’s your turn to be the main character!

I also kept thinking, “I should start taking care of myself,” but honestly, I hesitated because of the pain. The “Onda lifting” introduced today is a method that passes energy through the skin’s surface and delivers it directly to the target layers, the dermis and fat layer.

Onda lifting:

  • 2.45GHz microwave: keeps the skin surface cool while heating the inside!

  • Cooling system: because it keeps the skin surface cool throughout the procedure, you can barely feel any heat or pain.

Two key handpieces of Onda lifting

Onda lifting strategically uses two tips depending on the area of concern.

3mm handpiece (elasticity & tightening)

It focuses energy on the upper and middle dermis. By contracting collagen fibers and inducing new collagen production, it helps make the skin firmer. It’s excellent for fine lines and improving skin texture!

7mm handpiece (fat destruction & contour refinement)

It penetrates into the deeper layer where fat cells are located. It helps target areas where unnecessary fat has built up, such as a double chin or jowls. This is where the effect of making the face look smaller can be achieved.

Three key advantages of Onda lifting

① The biggest barrier to lifting procedures is pain. Onda lifting protects the skin with cooling energy throughout the procedure, so it feels more like a cool massage. It’s so comfortable you may wonder, “Is this really lifting?”

② The most representative effect of Onda lifting is improved skin elasticity. Even immediately after the procedure, you can see the facial line looking more defined, and as time passes, collagen is remodeled and elasticity gradually builds up. Usually, it looks best after about 3–4 weeks.

③ There is almost no bruising or swelling, making it ideal for busy office workers! There may be slight redness after the procedure, but it disappears within a few hours, so you can return to daily life right away.

What is Onda lifting’s KJ (kilojoule)?

Usually, when people think of lifting, they are familiar with the term number of shots. (For example: Shurink 300 shots, Ulthera 400 shots.) But Onda lifting works a little differently.

  • Shot: the number of times it is fired once, with a quick tap! (stamp-like method)

  • KJ (Energy): the total amount of heat energy accumulated in the skin during the procedure (rubbing method)

Because Onda delivers energy continuously while the handpiece is moved over the skin (rubbing), what matters is not how many times it is fired, but “how much heat energy has been steadily accumulated in the skin.” That is why the unit used is kJ.

A higher kJ value is not always better! Depending on your skin thickness and amount of fat, the appropriate kJ should be determined so that you can expect safe, smooth contour results without risk.

  • Partial treatment (double chin, etc.): around 40–50 KJ

  • Full facial contouring: around 80–100 KJ or more

If skin elasticity has started to decline, it is important to begin care early. Once elasticity drops, it takes a long time to recover! If you are considering your first laser lifting procedure, we recommend Onda lifting, which you can start without a heavy burden.

Since everyone has different skin thickness, fat volume, and degrees of sagging, choosing the right lifting treatment is important, but choosing a trustworthy, verified clinic is equally important! Wooa Plastic Surgery provides each visiting patient with enough time for consultation, and the procedure is carried out with careful attention.
