HIFU Sessions in Madrid: How Many and When Results Show

There is no fixed number of HIFU sessions: published studies usually assess the effect of a single session, and the doctor decides whether to repeat it based on your age, the degree of laxity and the area treated. Results are not immediate, because they depend on your skin forming new collagen, and the studies we cite assess them two, three and six months after the session. In this guide we explain why the process is gradual, what marks each stage, how to judge your progress sensibly and how we plan follow-up at Santé Madrid.

Key points

HIFU heats specific points beneath the skin and starts a repair process that forms new collagen, which is why the change comes gradually.

The studies cited in this guide assess results 60, 90 and 180 days after the session, not the next day.

The number of sessions depends on age, laxity, sun damage and the area; the medical team decides after an assessment.

To track your progress, photos taken in the clinic with the same lighting and the same angle work, not the mirror every day.

Results vary from one skin to another and no specific result can be promised.

Why HIFU results arrive gradually

HIFU (high-intensity focused ultrasound) concentrates energy in very small points located below the surface, much like a magnifying glass concentrates light. A review published in Clinical, Cosmetic and Investigational Dermatology explains that this heat creates thermal coagulation points in the deep dermis and the supporting layers, while the skin surface stays intact. At those points, collagen fibres contract and, in addition, the formation of new collagen begins.

That second part is what sets the pace. Forming collagen is a biological repair process, similar to the one that follows a small injury, and the skin does it at its own pace. The manufacturer of the Ultraformer MPT, Classys, describes this sequence in phases: after heating, fibroblasts, the cells that produce collagen, are activated, and the skin's natural repair mechanism gradually remodels its structure to improve elasticity and firmness.

That is why the same review notes that the response depends partly on each person's healing capacity. Two people with the same session can progress differently, and that does not mean the treatment has failed.

What studies say about timing

Studies do not measure the result the next day, but weeks and months later. In the review on focused ultrasound, several of the studies included assess patients 90 days after the session, and some also at 180 days. In one of them, on the décolletage, the proportion of people with improvement in wrinkles was higher at 180 days than at 90. There is an important nuance: those studies were done with a different focused ultrasound device, not with the Ultraformer MPT.

With a device from the same family, a study with the Ultraformer III published in 2022 treated 12 people with a single session on the forehead, temples and cheekbones, and measured progress at 60 and 90 days with standardised photographs. Some measurements around the eyes had already changed at 60 days, while the brow lift only became significant at 90 days. The authors observed no serious side effects.

These are small studies, with selected patients, and they do not allow anyone to predict what will happen in your case. What they do show is a pattern: the change is assessed over months and can keep progressing after the first weeks.

How many sessions you need: what it depends on

The studies cited assess the effect of a single session, but there is no figure that is valid for everyone. The review on focused ultrasound indicates that the treatment is best suited to mild or moderate laxity, and that older people, or those with more sun damage or more laxity, may need more energy in one session or more than one session to get the maximum benefit. It also points out that not everyone obtains an aesthetic benefit, and that choosing well who is treated and explaining realistic expectations is part of the treatment.

These are the factors the doctor takes into account:

Age and skin quality. The response depends partly on the ability to form new collagen.
Degree of laxity. Mild laxity is not approached in the same way as more marked laxity.
Area. The eye contour is not the same as the jawline or the double chin.
Habits that affect healing, such as smoking.

Classys describes in its Ultraformer MPT product page that before treating, the area is assessed and the number of shots needed is decided according to individual factors such as asymmetry and the severity of sagging. The Santé Madrid medical team proposes a plan after the assessment and reviews it during follow-up, without committing in advance to a number of sessions.

An indicative HIFU timeline

This table summarises what usually happens at each stage. The timeframes in days come from the studies cited above; the rest are general descriptions without figures, because real progress depends on each person and on the area treated.

Moment	What may happen	What to do
Day of the session	The energy is applied and collagen contraction begins; the skin may look a little red	Follow the doctor's instructions and take reference photos in the clinic
First days	There may be temporary redness or swelling and, sometimes, a bruise	Do not judge the result yet; let us know if something does not improve
First weeks	The skin is forming new collagen; the change is usually subtle	Protect your skin from the sun and keep your usual routine
Around 60 days	In the Ultraformer III study, some measurements around the eyes had already changed	Assess progress with perspective, without comparing daily
Around 90 days	This is the point at which several of the cited studies are assessed	Review with photos taken under the same conditions
Around 180 days	Some studies still see improvement or see it maintained	Decide with the doctor whether to repeat and when

Redness, temporary swelling and occasional bruising are the effects most often described in the review on focused ultrasound. Less often, dark marks after inflammation, temporary numbness or linear marks on the skin have been described. If you notice something you did not expect, write to us so we can check it.

When it is better to wait before starting

HIFU works with heat beneath the skin, and there are situations in which the doctor prefers to wait, treat another area or consider another approach. The review on focused ultrasound lists several of them. This list does not replace a medical assessment.

Also tell the doctor if you smoke or have any healing problem, because the same review mentions these as factors that can alter the response. Waiting a few weeks for a flare-up or a lesion to settle does not change the final result, and it does reduce risks.

How to assess your progress without obsessing

The mirror every day is not a good tool for following a slow change. Bathroom lighting, the time of day, rest or fluid retention change a lot of what you see, and it is easy to think nothing has happened or, the other way round, that everything has changed at once. That is why studies compare standardised photographs, taken before treatment and at each check-up under the same conditions, as the Ultraformer III study does.

In practice, this is what helps:

Reference photos taken in the clinic on the day of the session, with the same lighting, distance and angle.
New photos at the review, repeating exactly those conditions.
A neutral expression and hair tied back, to see the contour clearly.
Comparing the photos with the doctor, who knows which changes are expected in your area.

These photos are for your clinical follow-up, not a promise of a result. Sometimes the change is subtle and is easier to see in the contour than in a specific wrinkle.

Maintenance and combining with other treatments

Facial ageing does not depend on laxity alone. The review on focused ultrasound points out that collagen loss, fat redistribution and bone changes also play a part, and that no single treatment corrects all of that. That is why it describes combining it with intense pulsed light and with poly-L-lactic acid, and advises doing the pulsed light before the ultrasound when they are combined on the same day, because the redness HIFU leaves could increase light absorption.

The Santé Madrid catalogue includes options that can complement HIFU depending on the case, always after a medical assessment:

AFT pulsed light from the Harmony XL Pro platform, for pigmentation and redness.
Sculptra, which is poly-L-lactic acid, to stimulate collagen in specific areas.
Skin boosters or polynucleotides, for skin quality.
INDIBA radiofrequency, as a complementary in-clinic treatment.

As for maintenance, there is no fixed schedule. The sensible approach is to review the results and decide with the doctor whether to repeat an area and when, depending on how your skin has responded.

How we work at Santé Madrid

Our clinic is at C. de Amador de los Ríos, 1, Chamberí, 28010 Madrid, and we work with Ultraformer MPT HIFU on face and body. On the face we treat the double chin, the eye contour, the mouth area, the upper third with the so-called ponytail effect and the full face. This is the usual pathway:

First consultation. You can start with an aesthetic assessment with a Beauty Coach, which is free, or with a medical consultation for €50 (the price of the consultation, not of the treatment).
Medical assessment. The Santé Madrid medical team reviews your laxity, your skin, your history and what you hope to achieve, and tells you clearly whether HIFU makes sense in your case.
Plan. We explain which areas to treat, whether one session is enough to begin with and when we will review your progress.
Session and reference photos. We take the photos in the clinic under controlled conditions so we can compare later.
Review. Together we assess the change using the photos and decide whether to repeat, combine or simply maintain.

If you would like to get to know the clinic before booking, we tell you about it in our introduction to Santé Madrid. Results vary from one skin to another and we do not promise a specific result.

Frequently asked questions

Is one HIFU session enough?

There is no fixed number. The studies cited assess the effect of a single session, and the plan is reviewed afterwards. If there is more laxity or more sun damage, the doctor may propose more energy or a second session. It is decided after the assessment and the review, not in advance.

When will I notice the HIFU result?

The change is gradual because it depends on your skin forming new collagen. The studies cited in this guide assess results at 60, 90 and 180 days. Results vary from person to person.

Is it normal not to see anything in the first weeks?

Yes. In the first weeks the skin is in the middle of its repair process and the change is usually subtle. That is why it is best to wait for the review and compare photos taken under the same conditions.

How often is HIFU repeated?

There is no fixed schedule. The doctor reviews how your skin has responded and decides with you whether to repeat an area and when.

Can I combine HIFU with other treatments?

Yes, in many cases, after a medical assessment. It can be combined with pulsed light, Sculptra, skin boosters, polynucleotides or INDIBA. The order and the interval between treatments are decided by the medical team.

What side effects can there be?

The most often described are redness, temporary swelling and an occasional bruise. Less often, dark marks, temporary numbness or linear marks have been described. If something does not improve, it is best to have the doctor check it.

Why do they take photos of me in the clinic?

Because the mirror is misleading with slow changes. Photos with the same lighting, distance and angle allow an objective comparison at the review. They are for your follow-up, not a promise of a result.

HIFU calls for patience: the result builds over months and is better judged with photos than with the mirror. The first step is an assessment with the Santé Madrid medical team, who will tell you whether the treatment suits you and how to follow your progress.
