At what stage of jawline or neck sagging does Renuvion make sense?
Renuvion is generally discussed once sagging has gone beyond what surface-level devices address, but before it is pronounced enough to need surgery — a stage where the jawline edge has started to blur rather than just soften. Earlier stages are usually better matched to energy-based lifting or filler support, and more advanced sagging is usually discussed alongside, or instead of, Renuvion.

Sagging starts beneath the skin, not on it
Underneath facial skin sits a layer of fat, a sheet of fascia, and thin fibrous septa that hold the two together. With age or weight loss, those septa loosen, fat and skin slide downward, and the jawline edge blurs. Treatments that only act on the skin's surface have a natural limit, because the change they're responding to is happening underneath it.
This is also why the same word — 'sagging' — covers a wide range of what's actually going on beneath two different faces. Matching the treatment to the stage matters more than matching it to the word.
A rough way to think about stage
AUVEL Clinic uses a four-stage way of talking about jawline and neck sagging with patients, as a starting point for conversation rather than a diagnosis made from a description alone.
- Stage 1 — slight loss of firmness: energy-based lifting such as Ulthera, Thermage or Onda is often enough on its own
- Stage 2 — jawline softening: building support first with filler-based ligament lifting is often discussed before anything beneath the skin
- Stage 3 — a blurred jawline edge: this is where Renuvion is usually raised as a consultation topic, often planned together with ligament lifting
- Stage 4 — clear, pronounced sagging: the honest conversation is usually Renuvion combined with ligament lifting, or a surgical facelift, decided at consultation
Why depth is the real difference between treatments
Ulthera and Thermage send energy inward from the skin's surface, reaching the dermis or the fascia layer depending on the device. Thread lifts place threads in the fat layer and pull. Renuvion is different again: a thin cannula is placed beneath the skin through a small entry point, and heat is delivered directly to the fibrous septa that have loosened.
None of this makes one treatment better than another in the abstract — they're reaching different layers, which is exactly why stage matters more than preference when deciding between them.
At AUVEL Clinic, Renuvion is cleared in Korea and three handpiece sizes are available, chosen by area and stage at the consultation rather than by request.
What the device is actually cleared for
Renuvion uses helium plasma combined with radiofrequency energy, manufactured by Apyx Medical (USA). It is US FDA-cleared specifically for improving the appearance of loose skin of the neck and under the chin, based on a multicenter clinical study with blinded evaluators.
Jawline and double chin are also areas AUVEL Clinic treats with Renuvion, but it's worth being precise here: the device's FDA clearance is for the neck and submental (under-chin) area specifically. For other areas, the decision and expectations are set at consultation rather than by extending that specific clearance.
When it usually is not the right fit
At stage 1, where firmness has only mildly declined, Renuvion is generally not recommended — a surface-level device is usually enough, and starting with Renuvion would be treating a stage that hasn't arrived yet.
At the other end, where sagging is already pronounced, Renuvion alone tends to under-deliver. The clinic's honest recommendation at that stage is usually Renuvion combined with ligament lifting for support, or a conversation about surgical facelift, rather than Renuvion by itself.
A face that is only tightened without also addressing support and volume where it's needed tends to look pulled rather than natural, and tends to slip back over time — which is why AUVEL's doctors plan contraction, support and volume together rather than treating Renuvion as a complete plan on its own.
What to tell the clinic before you book
A side-profile photo can give a general sense of stage, but the assessment itself — including skin thickness and exactly where the sagging is coming from — is done in person.
The points below are worth raising when you first make contact.
- Whether you've had thread lifts, fillers or energy-based devices in the treatment area, and when
- Any bleeding disorder or blood-thinning medication
- Pregnancy, or thinking you may be pregnant
- Any event or deadline you're planning around, since Renuvion is not a same-day transformation

Frequently asked questions
How is Renuvion different from Ulthera or Thermage?
Ulthera and Thermage send energy inward from the skin's surface to the dermis or fascia. Renuvion enters beneath the skin through a small entry point and delivers heat directly to the loosened fibrous septa. They're generally matched to different stages of sagging rather than being interchangeable options.
Who should not get Renuvion?
People at a very early stage of sagging, where a surface-level device is usually enough, and people whose main concern is volume loss rather than loose tissue, are generally not good matches. This is confirmed at an in-person assessment.
Is Renuvion FDA-cleared?
Yes, specifically for improving the appearance of loose skin of the neck and under the chin. For other treated areas such as the jawline, the clinic's recommendation is based on assessment and experience rather than that specific clearance.
Can Renuvion be combined with ligament lifting?
Often, yes. Depending on your stage, contraction (Renuvion) and support (filler-based ligament lifting) are frequently planned together, since tightening alone can look unsupported if the underlying structure also needs it.
What if I'm actually at a more advanced stage than I think?
That's one of the main reasons the assessment happens in person rather than from a description. At a more pronounced stage, the honest recommendation may be Renuvion combined with ligament lifting, or a conversation about surgical facelift instead.
Can I send a photo before flying to Seoul?
A side-profile photo over WhatsApp in English or Chinese can give a general first read and help plan the visit. The confirmed assessment of stage and treatment plan happens in person.
