ONDA lifting for a sagging double chin

ONDA lifting is noninvasive body contouring that delivers 2.45GHz microwave energy to subcutaneous fat, targeting both fat-cell breakdown and dermal collagen remodeling.

The key principle is selective heating of the underlying fat layer while continuous cooling protects the skin surface.

It is used for localized fat under the chin, on the abdomen and flanks; the double-chin area has a relatively substantial body of brand-specific clinical research.

It is more accurate to view it as improving localized volume and firmness, rather than completely removing fat.

Even among lifting treatments, the layers reached by the energy differ.

Radiofrequency broadly heats the dermis to improve firmness, while focused ultrasound concentrates energy point by point as deep as the fascial layer.

ONDA differs in its target layer: microwaves reach subcutaneous fat and impose metabolic stress on fat cells themselves.

The choice therefore depends on whether jawline firmness alone is the issue or fat is also present under the chin.

ONDA is considered first when fat and sagging coexist; radiofrequency or ultrasound may also be considered when loss of firmness is prominent.

Double chins broadly arise from fat accumulation or skin sagging.

According to criteria proposed by an international advisory board, the most suitable candidates are non-obese people with localized fat and mild to moderate laxity.

If sagging originates in muscle itself or deeper structures beneath the fascia rather than the skin, ONDA alone may not deliver the expected change.

In such cases, it is realistic to discuss other approaches during consultation.

A clinical report using 6 ten-minute submental sessions at 2-week intervals found a significant improvement in laxity scores from baseline; around 70% rated themselves satisfied or better at 12 weeks.

More recently, a small study using a new handpiece for just 2 ten-minute sessions one month apart also found improved laxity scores.

However, this involved only around 10 participants, and no comparative study has yet established superiority.

Noticeable changes often develop gradually from around 4 weeks, with individual variation.

Clinical reports describe possible temporary erythema, tenderness, warmth and, rarely, palpable nodules.

Nodules are thought to arise during fat breakdown and usually settle naturally within several months, but very rarely persist longer, making follow-up necessary.

A thorough prior consultation is needed for people taking anticoagulants, those with scars, tattoos or structural abnormalities in the treatment area, and those with thyroid disease.

All three clinical studies reported few adverse effects, but these were short-term follow-ups involving only 10–48 participants.

I prioritize ONDA for people with localized under-chin fat and some laxity who find procedures requiring recovery time burdensome.

Although liposuction remains a standard for localized fat reduction, ONDA can be a practical alternative for those who do not want surgery.

If fat volume is substantial or the primary cause is structural sagging, results may fall short, so I also discuss other approaches.

Recommending treatment unconditionally may be easier for a clinic, but explaining when it does not fit is ultimately more helpful to patients.

We assess fat volume, skin elasticity and the desired degree of change together during consultation (individual results vary).
