Sinnonhyeon dermatology, Onda lifting effects? Cycle? All about it | Gangnam Seoul, Korea Dermatology Clinic Guide

Key summary: Onda Lifting is neither a treatment everyone with facial fat should get nor a routine to repeat mechanically every four weeks. The key is to first distinguish fat that can be reduced from volume that should be kept, and then judge the next session and interval while checking the changes after each treatment.

The two questions people ask first about Onda Lifting

Questions from people looking into Onda Lifting usually come down to two. Does it really help with a double chin or a full face, and if one session went well, is it fine to keep getting it every four weeks?

In reviews, you often see people say their jawline became sharper or that they chose Onda Lifting because of a double chin. So some people think of Onda Lifting first whenever they feel their face is full or their jawline is blurred.

Onda Lifting is indeed a device whose suitability is reviewed by looking at facial fat distribution and skin condition together. However, what I weigh first in the clinic is whether this face really needs Onda Lifting right now. Not every face looks large because of fat, and the reasons a jawline looks collapsed differ from person to person.

Before judging the effect: what Onda Lifting does

If you think of Onda Lifting as a treatment that pulls the whole face up strongly, that is some distance from reality. The areas where I consider Onda Lifting are places like under the chin and the lower face, where a lot of fat has gathered and the skin also looks looser than before.

Even when the concern is in the same area, not everyone is treated the same way. The strength of Onda Lifting is that it can work both toward reducing localized fat and toward firming and refining the skin, and how much weight to give each side differs from face to face.

Looking full is not the same as having fat to reduce

Before expecting results from Onda Lifting, there is one distinction to make. A face that looks full and a face that actually has a lot of fat that can be reduced are two different things.

Take a face where the area under the cheekbones and the side cheeks are already hollow, while volume has gathered only around the jaw. If volume is reduced across the whole face, the jawline may become lighter but the hollowness of the midface can become more noticeable.

On the other hand, for someone with ample fat under the chin, the treatment area can be reviewed with that area at the center. The degree of skin laxity also needs to be considered: a face with little fat where only the skin has thinned and stretched, and a face where the weight of fat has blurred the jawline, call for different approaches.

The criteria I check before treatment

That is why I do not decide on Onda Lifting based only on body weight or face size. I estimate the thickness of the fat layer by palpation, holding the area under the chin with my hand, and also check whether any area has lost volume and where the face actually looks heavy from the front and the side.

Going through this process, there are also cases where I end up not recommending Onda Lifting. For someone who naturally has little facial fat and very hollow cheeks, a different kind of elasticity care may suit better than reducing fat.

It is like a famous pair of shoes being useless if they do not fit your feet. With Onda Lifting too, what comes first is not whether the device is good but whether there is clearly something in your face that needs reducing.

Should you simply follow a four-week interval?

When you look into Onda Lifting, you often come across the phrase four-week interval. But it does not mean every face should repeat the same number of sessions every month.

The actual interval is better decided after checking your current skin condition, your reaction to the previous treatment, and the treatment area. When judging the interval, what matters more than the date is what changed in the face after the last session.

For example, if concern about lower-face volume has decreased after the first treatment but skin elasticity now bothers you a little more, it is worth reconsidering whether to repeat the same approach as the first time. Conversely, if areas that need treatment clearly remain, whether an additional session is needed can be checked step by step.

This means the treatment area and goals can change from session to session, even for the same person. Rather than setting the number of sessions and the period from the start, such as three sessions four weeks apart, I tend to look at fat distribution and skin elasticity and check the changes from the previous session to gauge whether another one is needed.

Avoid thinking that more sessions mean a smaller face

Onda Lifting should not be planned on the idea that the more you get, the smaller your face becomes. If the plan is to reduce volume, carefully deciding how far to apply it is an essential step.

You also do not need to decide on the next session right away based only on how you look immediately after treatment. The time it takes for skin condition and the face line to look different varies from person to person, so deciding after a few days that nothing has changed and booking another session right away can be a premature judgment.

When judging the interval, you need to look at the face rather than the calendar. Which areas have shrunk, how much skin texture and elasticity have been refined, and whether any volume should now be left untouched are compared side by side with the pre-treatment appearance and used as the criteria.

Recovery and precautions

After Onda Lifting, temporary reactions such as redness, warmth, and tenderness may appear depending on the person. The changes you notice and the number of sessions needed also vary with skin condition, amount of fat, and treatment area.

Onda Lifting cannot be declared finished after one session, nor can it be fixed as care that comes back every set month. If you consult a dermatology clinic near Sinnonhyeon about Onda Lifting, I recommend hearing not only how many weeks apart to come, but also which areas of your face are meant to be reduced and what will be used to judge whether a next session is needed.

Frequently asked questions

Fat has gathered only under my chin. Do I need to treat the whole face?

Not necessarily. If the concern is concentrated under the chin, you can consider proceeding with Onda Lifting centered on that area while leaving volume elsewhere intact.

I have little facial fat, but my jawline is unusually blurred.

A blurred jawline is not always caused by fat. If skin elasticity or other structures play a bigger role, a different lifting method may suit better than reducing fat.

If I am satisfied after one session, do I need more?

If the change you aimed for is sufficient, you do not have to get additional sessions. After some time, you can look again at fat distribution and skin, and plan the next session when it becomes necessary.

Can I get it again before four weeks have passed?

Rather than repeating the same area at too short an interval, it is important to watch the changes after the last treatment sufficiently before judging the interval.
