What is Volnewmer?

Volnewmer is a monopolar radiofrequency (RF) device made by CLASSYS, a Korean medical device company, and it works at a frequency of 6.78 MHz. It heats the dermis, the collagen-rich layer under the skin surface, through a tip that is cooled with circulating water while the energy is delivered. Nothing breaks the skin: there are no needles and no incisions.

At SkinRev Lab, Volnewmer is the device behind VF Lift, a medical lifting treatment that Dr Sin Yong, our medical adviser, performs himself at CityLink Mall, by City Hall MRT. VF Lift is priced at consultation, so this page carries no price.

This guide explains the device rather than the treatment plan. It covers:

  • what the maker publishes about the frequency, the cooling, the pulse and the four tips;
  • how radiofrequency heating differs from focused ultrasound (HIFU);
  • how Volnewmer is used at SkinRev Lab, as our VF Lift page describes it;
  • what the published research on this device has and has not measured;
  • who is usually asked to wait or choose something else.

Where a fact comes from the maker or from a journal, the source is listed under References at the end of the page. Where SkinRev Lab's own practice is described, it is taken from our treatment pages and nothing is added to it.

How does 6.78 MHz monopolar radiofrequency work?

Monopolar radiofrequency warms tissue by passing an alternating electrical current through it; the tissue resists the current, and that resistance turns into heat. The maker describes Volnewmer as a monopolar system in which a single electrode in the tip delivers the energy into the skin, at a radio frequency of 6.78 MHz.

Three points explain how this behaves in the skin:

  • Heat spreads through a volume. Radiofrequency does not focus to a point. It warms a block of tissue under the tip, which is why it is often described as bulk or volumetric heating.
  • The target is the dermis. CLASSYS states that Volnewmer targets the papillary and reticular dermis, the upper and lower parts of the dermis, while the surface is protected by contact cooling. The maker does not publish a depth in millimetres, so this page does not give one.
  • Collagen responds to heat. Warmed collagen fibres tighten, and the skin then lays down new collagen as part of its repair response over the following weeks. The maker lists firming and tightening lax skin and stimulating collagen in the dermis as the purpose of the device.

Before any treatment there is an assessment: skin thickness, the amount of fat under the skin and the degree of laxity all shape the plan, and your doctor will advise whether RF is the right energy for your face at all.

What does CLASSYS publish about the Volnewmer device?

CLASSYS publishes the frequency, the cooling method, the pulse type and four tip sizes for Volnewmer on its product page. The table below repeats those published specifications and nothing else.

FeatureWhat the maker states
Energy typeMonopolar radiofrequency, single electrode
Frequency6.78 MHz
Power115 W
CoolingContinuous water cooling through the tip, in contact with the skin
PulseSingle pulse, with an impedance check by the tip before energy is delivered
Target layerPapillary and reticular dermis
I Tip, 0.25 cm²Small areas such as around the eyes, the nose and the marionette lines
F Tip, 3.0 cm²Jawline and chin
V Tip, 4.0 cm²Main tip for the face
S Tip, 16.0 cm²Body areas: abdomen, arms and thighs
HandpiecesTwo

The maker also describes a curved, tilted tip head for the contours of the face, and a design in which the electrode edges sit inside the tip so that they do not rest on the skin.

Several things are not published on the maker's product page: the number of pulses in a session, the pulse length, the temperature reached in the skin and a depth in millimetres. Our own VF Lift page does not state which tips are used for which zone either. Those are decisions the doctor makes for each face, and they are explained at consultation.

How is Volnewmer used at SkinRev Lab?

At SkinRev Lab, Volnewmer is used for VF Lift, and Dr Sin Yong performs the treatment himself. Our VF Lift page describes it as a radiofrequency-only protocol: there is no focused ultrasound in VF Lift.

The page sets out the method in these terms:

  • Vertical vectors. The water-cooled tip is moved along vertical lines planned for the face, instead of being stamped in a uniform grid.
  • Settings by zone. Energy settings are adjusted zone by zone under three headings the protocol uses: Lift, Reduce and Restore.
  • Time in the chair. A session for the face and neck takes around 60 to 90 minutes, depending on the plan.
  • A planned course. The number of sessions is set at consultation, with review visits.
  • Price. VF Lift is priced at consultation.

Our technology page lists the same pairing: Volnewmer for VF Lift, 6.78 MHz monopolar radiofrequency through a water-cooled tip, performed by Dr Sin Yong.

Dr Sin Yong also teaches this protocol. According to our conference record, he was an invited trainer at the CLASSYS Academy in São Paulo, Brazil, in September 2026, where he taught doctors his VF Lift protocol on Volnewmer, and he presented a talk on Volnewmer and the VF Lift at the 7th CLASSYS APAC Symposium in Bangkok in June 2026.

One honest limit belongs here. The VF Lift page states that no peer-reviewed study has yet tested this exact protocol. The research below concerns the device and the energy type, not the VF Lift method.

How is Volnewmer different from HIFU?

Volnewmer uses radiofrequency, which is electrical energy that heats a volume of dermis; HIFU uses focused ultrasound, which is sound energy that places small points of heat at set depths. They are different tools, and one does not replace the other.

  • Energy. Radiofrequency is an electrical current. Ultrasound is a sound wave focused in the way a lens focuses light.
  • Shape of the heat. RF warms tissue in bulk beneath the tip. Focused ultrasound makes separate small coagulation points in rows.
  • Layer. The maker states that Volnewmer targets the dermis. HIFU cartridges are named by focal depth; on the face, our HIFU page lists 1.5 mm, 3.0 mm and 4.5 mm, the last reaching the SMAS, the fibrous layer over the facial muscles.
  • At SkinRev Lab. Both are medical treatments performed by Dr Sin Yong: VF Lift on Volnewmer, and HIFU on a separate ultrasound device named on that page.

Which energy fits depends on what is causing the concern: loose, thin skin, descent of the deeper layers, or fullness under the chin. That is decided by examination, and some faces are advised to have neither.

People often ask about other monopolar RF devices too. Thermage and Oligio are monopolar radiofrequency devices from other makers. SkinRev Lab does not offer Thermage or Oligio; our Thermage guide and Oligio guide describe those devices by their published specifications.

What happens during and after a Volnewmer session?

A session involves a consultation and skin check, then the doctor passing the cooled tip over the planned zones, with warmth felt at each pulse. Our VF Lift page gives around 60 to 90 minutes for the face and neck.

During the session

  • The tip checks skin impedance before energy is delivered, as the maker describes, and the water cooling runs throughout.
  • Each pulse is felt as heat that builds and fades. Tell the doctor how each zone feels, because settings can be lowered. In one published study of this device, the energy level was reduced for participants who reported heat discomfort.

Afterwards

Our VF Lift page describes downtime as usually minimal:

  • redness and warmth on the day of treatment;
  • swelling or tenderness along the jawline or under the chin that can last one to three days;
  • gentle skincare and daily sunscreen while the skin settles;
  • no saunas, hot workouts or intense exercise until the skin has settled.

Contact the clinic if you notice blistering, a crust, a firm lump, a dent in the skin, or pain or swelling that is increasing instead of easing. These are uncommon, and they should be examined promptly. Your doctor will advise on anything specific to your skin and medical history before you leave.

What does the research on Volnewmer show?

Published research on this device is early: the peer-reviewed clinical studies that name it are few, small and short. It is worth knowing exactly what was measured.

One device study. A February 2024 paper in Plastic and Reconstructive Surgery Global Open studied the Volnewmer device. Fifty people enrolled and 45 completed a one-month follow-up. Each received 200 to 300 pulses with the 4 cm² tip. Skin surface roughness was measured from three-dimensional scans before treatment, straight afterwards and at one month. The study had no comparison group, a cosmetic product was applied under plastic wrap after the procedure, and the author called for larger and more diverse groups. It does not show how long any change lasts.

The energy type. Monopolar radiofrequency has a longer record on an earlier device from another maker. A retrospective review of more than 600 treatments, published in 2006, reported temporary side effects in about 2.7% of treatments. Redness and swelling lasting less than a day were described as common straight after treatment; the recorded side effects included swelling for up to a week, small bumps, a surface crust, small lumps under the skin, tenderness of the neck and, in one case, a slight depression in the cheek. That review concerned a different device and older settings, so it describes the class of treatment, not Volnewmer.

What is missing: long-term follow-up, controlled comparisons, and any trial of the VF Lift protocol itself. For that reason this page makes no claim about results, and a consultation will not promise one.

Who is Volnewmer suited to, and who should wait?

Radiofrequency skin tightening is generally considered for mild to moderate skin laxity in adults who want a treatment without needles or incisions; it is not a substitute for surgery where there is heavy sagging with excess skin. Suitability is decided by Dr Sin Yong at consultation, after examining the skin and taking a medical history.

Our VF Lift page lists these reasons not to have the treatment:

  • pregnancy;
  • a pacemaker or another implanted electronic device;
  • metal implants in the treatment area;
  • infected or inflamed skin in the area.

Tell the doctor about anything else that could matter:

  • recent injectable treatments, threads or surgery in the area;
  • a history of keloids or slow healing;
  • skin conditions that flare with heat;
  • medicines that thin the blood or affect healing;
  • dental work, braces or implants near the area to be treated.

Concerns that RF does not address are named plainly at consultation. Heavy laxity with excess folds of skin, and hollowing where the hollow is bony, may be better served in other ways, and the doctor may suggest a different treatment or none. If a non-medical option is closer to what you want, SKINLIFT® and SKINTIGHT® are performed by our Aesthetic Therapists and are separate from the medical treatments described here.

How do I ask about Volnewmer at SkinRev Lab?

Ask for a VF Lift consultation with Dr Sin Yong; VF Lift is the facial treatment at SkinRev Lab that uses Volnewmer. The consultation is where suitability, the number of sessions and the price are set out, since medical treatments here are priced at consultation.

Useful questions to bring, here or anywhere you are considering a monopolar RF treatment:

  • Which device will be used, and who will hold the handpiece?
  • Which zones will be treated, and with which tip?
  • What will it feel like, and can settings be lowered during the session?
  • What should I expect in the first three days?
  • What would make you advise against this treatment for me?
  • What does the published evidence cover, and what does it not?

SkinRev Lab is at #B1-28 CityLink Mall, 1 Raffles Link, by City Hall MRT, and is open daily from 11am to 8pm. You can message us on WhatsApp at +65 8266 9585 to arrange a time.

Common questions

Your questions,
answered

What is Volnewmer?

Volnewmer is a monopolar radiofrequency device made by CLASSYS. It works at 6.78 MHz and delivers energy through a water-cooled tip to warm the dermis, the collagen-rich layer of the skin. It involves no needles or incisions. At SkinRev Lab it is the device used for VF Lift, performed by Dr Sin Yong.

Does SkinRev Lab offer Volnewmer in Singapore?

Yes. SkinRev Lab at CityLink Mall, City Hall, uses Volnewmer for VF Lift, a medical lifting treatment that Dr Sin Yong, medical adviser, performs himself. It is described on our VF Lift treatment page as a radiofrequency-only protocol planned along vertical lines of the face, and it is priced at consultation.

How much does Volnewmer cost at SkinRev Lab?

VF Lift, the facial treatment that uses Volnewmer at SkinRev Lab, is priced at consultation, so we do not publish a figure. The price depends on the zones treated and the plan Dr Sin Yong sets after examining your skin. You can arrange a consultation by WhatsApp on +65 8266 9585.

Is Volnewmer the same as Thermage?

No. They are separate devices from different makers. Both are monopolar radiofrequency devices, but their tips, cooling methods and pulse designs are each maker's own. SkinRev Lab offers VF Lift on Volnewmer and does not offer Thermage. Our Thermage guide describes that device by its published specifications.

Is Volnewmer a type of HIFU?

No. Volnewmer uses radiofrequency, an electrical current that warms a volume of dermis. HIFU uses focused ultrasound, which places small points of heat at set depths. At SkinRev Lab the two are separate medical treatments, VF Lift and HIFU, each performed by Dr Sin Yong after a consultation.

How long does a Volnewmer session take?

Our VF Lift page gives around 60 to 90 minutes for the face and neck, depending on the plan. That includes moving the cooled tip along the planned lines zone by zone. The consultation and skin check come first, so allow extra time on a first visit.

What is the downtime after Volnewmer?

Downtime is usually minimal. Redness and warmth on the day are expected, and swelling or tenderness along the jawline or under the chin can last one to three days. Gentle skincare and sunscreen are advised, and saunas, hot workouts and intense exercise are avoided until the skin settles.

Who should not have a Volnewmer treatment?

Our VF Lift page lists pregnancy, a pacemaker or other implanted electronic device, metal implants in the treatment area, and infected or inflamed skin as reasons not to have it. Other conditions and medicines are reviewed at consultation, and your doctor will advise whether the treatment is appropriate for you.
