The maintenance conversation happens at the end of a course, when a person has already paid, already seen whatever they are going to see, and is emotionally invested in the result. It is the worst possible moment to discover that the effect requires continuing payment.
This article moves that conversation to before you start.
Three kinds of effect
Banked. Something is destroyed or removed and does not return. Cryolipolysis injures fat cells that are then cleared. Injectable fat dissolving destroys fat cells directly. In both cases the cells do not regenerate in that place, and to that extent the change is durable.
Maintained. A response is provoked, and the response fades when the provocation stops. Radiofrequency and focused ultrasound provoke collagen remodelling, which is subject to ordinary ageing afterwards. Muscle stimulation provokes adaptation, which reverses when the stimulus stops, exactly as it does for anybody who stops training.
Temporary. Something is moved rather than changed. Wraps and drainage move interstitial fluid, which redistributes within hours to days.
The caveat on banked effects
Banked does not mean fixed, and this is the point clinics are least keen to make.
The appearance of a fat deposit depends mainly on the size of the fat cells within it, not only on how many there are. Fat cells enlarge and shrink substantially with energy balance. An area treated by a cell-destroying method has fewer cells afterwards, and those remaining cells still respond to weight change like any others.
So a person who gains weight after a treatment can find the treated area larger than it was immediately afterwards, without a single destroyed cell having returned. Both statements are true: the reduction was permanent, and the area got bigger. When you hear permanent, the correct mental translation is that the cells will not come back, not that the area is fixed.
“Permanent results after a single course.”
What would have to be true
- That the mechanism destroys tissue rather than stimulating a response, since only destruction is permanent.
- That permanence of a tissue change is the same as permanence of an appearance, which it is not.
- That the course being sold is the whole of what will be recommended.
What is actually established
- Where fat cells are destroyed, those cells do not return in that location.
- The appearance of an area depends mainly on the size of the fat cells present, which changes with weight.
- Effects produced by remodelling or adaptation fade without continued stimulus, which is ordinary physiology.
Permanent is usually defensible about the tissue and misleading about the outcome. The question that settles it is which mechanism is involved: destruction is banked, stimulation is rented, and fluid is neither.
The rebound question
People often ask whether stopping makes things worse than before. In general, no.
Collagen produced through remodelling ages at the normal rate; it does not disappear faster than it would otherwise have arrived. Muscle adaptation reverses towards baseline rather than below it. Fluid returns to normal distribution.
What can create the impression of a rebound is that a person's baseline was moving anyway. Ageing continues. Weight changes. Stopping a treatment at the same time as any of those is happening produces a change that gets attributed to the stopping.
The recognised complication that genuinely leaves an area worse is paradoxical adipose hyperplasia after cryolipolysis, in which the treated area enlarges. That is a complication of treatment, not a consequence of stopping it, and it is covered on the cryolipolysis page.
Establish which kind of effect you are buying
- Destruction of fat cells, as in cryolipolysis and injectable fat dissolving: banked, subject to weight change in the remaining cells.
- Collagen remodelling, as in radiofrequency and focused ultrasound: maintained, fading over months without further treatment.
- Muscle adaptation, as in stimulation devices: maintained, reversing as any training effect reverses.
- Fluid movement, as in wraps and drainage: temporary, resolving within hours to days.
- Combined devices: establish which mechanism the clinic is relying on for the result being promised.
- Any treatment sold with an indefinite maintenance plan: the maintenance is the product, and it should be priced as such.
The question to ask is short: if I stop after the course, what happens over the following year? A clinic that answers it precisely understands its own equipment. A clinic that says the results are permanent without qualification does not, or is choosing not to.
Seeing it as a subscription
For maintained effects, the clearest way to think about the purchase is as an annual subscription to a modest change in appearance.
That framing is not hostile. Plenty of things are worth paying for annually, and if a person values the effect and can afford it, that is a reasonable decision. What the framing does is put the decision in the right shape, because almost nobody agrees to an indefinite annual payment as readily as they agree to a one-off course, and the one-off course framing is doing work that the annual framing would not.
Work the number out using the method and decide against that figure rather than against the course price.
What to ask before you start
Ask whether the effect is produced by destroying tissue or by provoking a response. Ask what happens over the twelve months after the course if you have no further treatment. Ask what the maintenance recommendation is, in sessions per year. Ask whether the treated area will change if your weight changes, and by how much. Ask what they would expect to see if you returned in three years having done nothing.
Those five questions are not adversarial and they take two minutes. A practitioner who answers them precisely is demonstrating the understanding you want in somebody treating you, and a practitioner who deflects them is demonstrating something else.
