The limit, before anything else
There are three sentences this device cannot deliver, and promising them is the most common way to cheat a patient without quite lying:
That said, within its range PrimeX is very good — and the range is wide: a great many people do not need theatre, and do need more than a cream.
- "It will get rid of your belly." No. Where there is genuine fat volume, the result liposuction gives is of a different order. PrimeX refines; it does not empty.
- "It will tighten your excess skin." No. Radiofrequency improves moderate laxity. A skin apron after pregnancy or major weight loss is cut: that is an abdominoplasty. No energy substitutes for a scalpel when skin genuinely is excess.
- "You will lose weight." No. It is contour, not scales. If body mass index is high, weight comes first; contour is worked afterwards, and worked better.
How it works: two mechanisms, one session
This is the logic of the device, and why it combines two technologies rather than one:
The combination matters because the two problems usually arrive together: almost nobody has localised fat with no laxity at all. Treating only the fat in skin that has already lost tone can leave the area laxer than before — the classic failure of single-mechanism platforms.
- UltraWave — transverse ultrasound. It acts on the adipocyte in the treated area. Released contents are progressively reabsorbed over the following weeks, by the normal metabolic route.
- UniPolar — radiofrequency. It heats the dermis in a controlled way and stimulates neocollagenesis. This is the tightening component, and it is slow: collagen remodelling builds across months, not sessions.
- Patented rotational massage, built into the handpiece, improving tolerance and evenness of treatment.
Areas, sessions and what it feels like
It treats the abdomen, flanks, thighs, buttocks, arms and chin. Sessions are short — 8 to 30 minutes depending on the area — and need no recovery: you leave and carry on with your day. It is felt as warmth and a deep massage. It does not hurt.
It is not a one-off session, and anyone selling it as one is selling smoke: it is worked in a series, and the number is defined at the consultation according to area and starting point.
The effect on fat begins to show over the following weeks. The tightening component takes months, because it depends on new collagen. And it holds with stable weight: the device reduces fat in an area; it does not prevent gaining new fat. Results may vary.
Where it sits against the alternatives
The useful question is not "is PrimeX good?" but "is it what I need?". The honest answer is usually one of these:
That this conversation is had with a plastic surgeon rather than a seller of sessions is the only real guarantee you have that a problem solvable by an operation will not be put into a ten-session course — or the reverse.
- Moderate localised fat + some laxity → PrimeX. This is its indication.
- Fat only, in a well-defined area, and you do not want a course → cryolipolysis.
- Missing muscle, not excess fat → StarFormer.
- Moderate fat + laxity, and you accept a fibre under the skin → body endolift, which is stronger and genuinely a procedure.
- Genuine fat volume → liposuction or HD liposculpture.
- Excess skin → abdominoplasty. There is no shortcut.
The equipment
The Alma PrimeX (Alma, Israel) is used: body contouring with transverse UltraWave ultrasound against fat and UniPolar radiofrequency for collagen, with a patented rotational massage. Abdomen, flanks, thighs, buttocks, arms and chin, in sessions of 8 to 30 minutes.
Cost is defined at the consultation, according to area and the number of sessions in the series. See the price list.
Dr. Arístides Arellano is a plastic surgeon holding a specialty licence: he practises under a Mexican medical licence (D.G.P. 1125959) and a specialty licence in Plastic & Reconstructive Surgery (0002008), both issued by the Directorate General of Professions (DGP), which reissued his certificate of professional standing in 2025. His career began before Mexico’s present-day specialty-board system existed: he belongs to the founding generation of plastic surgery in Puebla, the second generation of a surgical tradition started in 1971 by Dr. Francisco Arellano Ocampo. Trust is verified, not promised: both licences are public and anyone can look them up in the DGP’s National Registry of Professionals.
Trust is verified, not promised. All 210 scanned documents —degree, licences, diplomas, publications and certificates, from 1977 to 2025— are open in Dr. Arístides Arellano’s credential archive, alongside an explanation of the difference between a specialty licence and a board certification.

The plan · the series and the result
- The session (8–30 min)Warmth and a deep-massage sensation. No pain and no recovery: you leave and carry on with your day. No anaesthesia, no stitches, no time off.
- Weeks 1–4Contents released from the fat cell are progressively reabsorbed by the normal metabolic route. The contour change begins to show.
- During the seriesWorked across successive sessions. Anyone selling a single session as the solution is selling smoke.
- Months 2–6Tightening builds. Neocollagenesis is slow by definition: it is the part of the result that demands patience.
- MaintenanceThe result holds with stable weight. The device reduces fat in an area; it does not prevent gaining new fat. Results may vary.
Frequently asked questions
Does PrimeX replace liposuction?
No. Where there is genuine fat volume, liposuction gives a result of a different order and will look better. PrimeX refines moderate localised fat and adds a tightening component; it does not empty an area. At the consultation you are told which of the two you are — even though a course of sessions is easier to sell than theatre.
I have hanging skin. Will radiofrequency tighten it?
Radiofrequency improves moderate laxity: skin that has lost tone but does not hang. A skin apron after pregnancy or major weight loss is tightened by no energy device — it is cut, and that is an abdominoplasty. Promising otherwise would be selling you a course that will not solve your problem.
Will I lose weight?
No. It is a contour treatment, not a scales treatment. And if body mass index is high to begin with, weight comes first: contour is worked afterwards, and worked better. Starting the other way round is paying for a result you are going to lose.
Does it hurt? How much recovery?
It does not hurt: it is felt as warmth and a deep-massage sensation, thanks to the handpiece’s rotational massage. No anaesthesia, no stitches and no recovery. Sessions last 8 to 30 minutes depending on the area.
Is one session enough?
No, and anyone selling it that way is selling smoke. It is worked in a series and the number is defined at the consultation, according to area and starting point. Besides, the tightening component depends on new collagen, which builds across months.
Why combine ultrasound and radiofrequency?
Because the two problems almost always arrive together: virtually nobody has localised fat with no laxity at all. Treating only the fat in skin that has already lost tone can leave the area laxer than before — the classic failure of single-mechanism platforms.
