Lysiwave is microwave body and face sculpting that heats every layer — not just the deep fat. No needles, no gel, no downtime.
Fat cells break down
Heat at 55–60 °C shatters the fat inside each cell into droplets. Your lymphatic system clears them over the following month. Gradual, natural, permanent.
Skin tightens
Your dermis is held at 40–42 °C — the exact temperature that switches fibroblasts into collagen production. Instant contraction, then new collagen for 12 weeks.
Cellulite releases
Cellulite isn’t fat — it’s tight fibrous bands pulling your skin down. Heat dissolves those stiff bands so the dimples flatten. A structural fix, not a temporary blur.
Fat: dielectric heating at 2.45 GHz; adipocyte lipid release and macrophage clearance.
Skin: 40–42 °C upregulates type I collagen synthesis in human dermal fibroblasts via HSP47 — in vitro plus 31-subject clinical arm, 2006; corroborated J Clin Med 2022.
Cellulite: MMP-mediated digestion of type I septal collagen, replaced by more elastic type III collagen — picrosirius red histology, Zerbinati, cited J Clin Med 2022;11:515.
Every microwave sculpting device uses the same 2.45 GHz frequency. The difference is what happens to your skin on the way down.
Thermal profile at depth. Based on manufacturer thermal mapping. Individual tissue response varies.
An ice-cold plate can’t chill your skin without chilling the layer underneath it — and that layer, your dermis, is where every bit of your tightening result is made.
Lysiwave cools with oxygen instead. So the dermis stays warm enough to rebuild.
Others give you fat loss.
Lysiwave gives you fat loss + tightening + smoother cellulite — in the same 30 minutes.
At OZ Aesthetic, we use a tiered medical approach to fat reduction.

At OZ Aesthetic, we use a tiered medical approach to fat reduction. We match the technology to your specific body goals:
| Other microwave devices | LYSIWAVE | |
|---|---|---|
| Skin cooling | Ice-cold plate pressed on your skin (~5 °C) | Cushion of chilled pure oxygen (~38 °C) |
| Layers treated | Deep fat only | Dermis + cellulite bands + deep fat |
| Skin tightening | Indirect — heat has to travel up | Direct dermal heating at 40–42 °C |
| Cellulite | Deep bands only | Surface + deep bands in one pass |
| Gel or oil | Required — messy, adds nothing | None. Oxygen is the medium |
| Bonus for your skin | — | 90%+ oxygen boosts circulation, hydration and glow |
| Consumables | Coolant, gel, oil | Zero |
| Safety cut-off | Cooling plate | Live sensor stops output above 41 °C |
| Face-capable | Limited | Yes — 3 mm applicator for chin & jawline |
No gel, no oil, no residue. Dress and go.
A pleasant breeze on top while the depth does the work.
Boosts microcirculation, hydration and skin permeability.
The whole reason you get tightening, not just fat loss.
The small 3 mm applicator is built for the submental area and lower face — where the fat pad is shallow and the skin is thin. Jawline definition, double chin, and that soft undefined lower face stuck between “needs fat reduction” and “needs tightening.”
Submental: 10 women with moderate–severe submental laxity, two 10-minute 2.45 GHz sessions 30 days apart — graded improvement at 12 weeks, no adverse events. Lasers in Medical Science, 2025. Small study.
Fat freezing alone has one classic problem: a smaller area that still looks loose.
Take volume out from under skin that has no plan to shrink, and you trade a bulge for a sag.
So we do both.
Cooltech Define — removes the volume
Freezes and destroys fat cells permanently. Best for a pinchable bulge.
Lysiwave — rebuilds the envelope
Tightens skin and releases the cellulite bands the cold can’t reach.
28.5%: highest mean caliper-measured fat reduction across a systematic review of 19 cryolipolysis studies (range 14.67–28.5%; by ultrasound 10.3–25.5%).

better overall improvement with the combination
In our experience at OZ, clients running both treatments together see distinctly better skin tightening and clearer cellulite improvement than either treatment on its own.
Cold and heat target different tissue — they don’t overlap, so nothing is wasted.
Timing — Lysiwave goes in about two weeks after freezing, so the tightening stimulus lands exactly while fat volume is falling.
Faster clearance — heat boosts circulation and lymphatic flow, the same route your body uses to clear the frozen fat cells.
Your 100-minute session is a customized, treatment-grade procedure—not a standard facial.
4–8 sessions, two to four per month, then maintenance every 6 months.
We reassess at session four rather than locking you into a package up front.
For stubborn fat, visible cellulite and skin that has lost its tone.

Lysiwave is not a weight-loss treatment and won’t fix significant loose skin after major weight loss or pregnancy. We’ll tell you that at assessment rather than sell you eight sessions.
You have a pacemaker or cardiac implant, metal implants in the area, a deep brain stimulator, active or recent cancer within 5 years, significant kidney or liver disease, active phlebitis, a clotting disorder, a transplanted organ, uncontrolled diabetes, or you’re pregnant or breastfeeding.

Same frequency, different skin interface. Machines that press an ice-cold plate onto you protect your skin
by chilling everything underneath it — including the dermis, the layer that produces your tightening result. LysiWave cools with oxygen instead, keeping the dermis at 40–42 °C where fibroblasts build new collagen. More layers treated means better tightening and cellulite improvement per session.
RF loses most of its energy in the top layer of skin, so it works mainly on the surface and takes a long time to heat deep tissue. Microwaves pass through skin easily and concentrate in fat, reaching working temperature within minutes. Fewer sessions, and genuine fat reduction rather than tightening alone.
No. Deep warmth with a cool draught on the surface. No numbing cream, no needles. Most clients work or scroll through it.
Skin often looks tighter straight away as existing collagen contracts. Fat reduction is gradual over about a month as your lymphatic system clears it. New collagen keeps forming for 8–12 weeks after your last session.
4–8 for tightening or cellulite, two to four per month. Fat reduction starts at four and continues to target. We review at session four.
Yes — the 3 mm applicator is designed for the submental area and lower face.
For most people, yes — that’s OZ FREEZE:FIRM. Cooltech Define removes the fat volume; LysiWave tightens the skin over it and releases the cellulite bands. We start LysiWave about two weeks after the freezing session.
Cells cleared by the process don’t come back. The remaining cells in the area can still enlarge if your weight goes up, so results hold best with stable weight.
None at all. The cooled oxygen cushion is the coupling medium — nothing goes on your skin and nothing needs wiping off.
A sensor in the emission window watches your skin continuously and cuts the microwave output above 41 °C. Published microwave studies report no severe adverse events, with histology showing intact skin and inflammation fully resolved at two months. We screen you for contraindications first.
