You’ve done it. Your skin hasn’t quite caught up yet.
Whether following weight loss, pregnancy or simply as we get older — sagging skin is not a question of discipline, but of elasticity. And that can be specifically improved.

Perhaps you've been there:
You’ve lost weight and you’re proud of it — but the skin on your tummy or upper arms is sagging and won’t tighten up.
After the pregnancy, the skin on my tummy remained soft and loose, even though I’d long since lost the weight.
You lose weight with a GLP-1 medication; the weight comes off quickly — but your skin doesn’t keep up.
Creams and oils promised to firm the skin; you used them every day — but deep down, where it really matters, nothing has changed.
You pinch your skin, and it doesn’t spring back like it used to.
You don’t want surgery or scars — but you’d like your skin to look firmer again.
Why the skin doesn’t keep up on its own
Skin is elastic, but not infinitely so. If it is stretched over a long period of time — due to weight, pregnancy or the passage of time — the collagen and elastin fibres in the connective tissue lose their elasticity. If the underlying volume then decreases rapidly, the skin lacks the structure to contract. It remains saggy. This is not a sign of a lack of discipline, but a question of skin elasticity.
This is particularly evident in cases of rapid weight loss with GLP-1 medicines such as semaglutide or tirzepatide. Subcutaneous fat supports the skin from within — if it is lost rapidly, the skin cannot keep up quickly enough. This is particularly noticeable on the upper arms, stomach and inner thighs.
What matters
- Elasticity, not weight — Loose skin often remains, even long after you’ve reached your ideal weight.
- Rebuilding collagen and elastin — it is only deep down, in the dermis, that elasticity can be restored.
- The earlier, the better — the sooner you start looking after your skin, the better it will cope.
- Stay honest — Mild to moderate sagging can be treated effectively, but significant sagging cannot be treated without surgery.
What really tightens the skin – and what doesn’t
Creams, oils and „firming" serums remain on the surface. However, sagging skin originates deeper down, in the dermis, where collagen and elastin are found — no cream can penetrate to that depth in sufficient quantities to be effective. They nourish the surface, but do not build up connective tissue.
Exercise builds muscle and can improve your figure — but it does not change the quality of your skin itself. And losing more weight often makes sagging skin more visible rather than firmer, as even more of the supporting tissue is lost.
What really firms the skin works deep down: it delivers a targeted stimulus to which the body responds by producing new collagen and elastin. This is exactly what RF microneedling and radiofrequency do — and this is exactly what we use.
Honest and important: When there is a great deal of excess skin — for example, following significant weight loss — non-surgical methods reach their limits. In such cases, a skin-tightening operation is the more honest solution. For mild to moderate sagging, however, targeted collagen stimulation is exactly the right approach.
How to tackle sagging skin
We stimulate the skin to regenerate — and support the surrounding tissue so that it can regenerate whilst being well nourished. Step by step, over several months.
Core treatments
Vivace® Body
Fine needles deliver radiofrequency energy precisely into the dermis — the most powerful stimulus for new collagen and elastin. Thanks to the patented needle technology, it is more comfortable to use than comparable devices. For the stomach, upper arms, thighs, knees and bottom.
Find out more →BTL Exilis® Body
Monopolar RF combined with ultrasound heats the dermis over a wide area and stimulates collagen contraction — providing complementary, extensive skin tightening to complement the Vivace® treatment.
Find out more →Accompanying
- Icoone® Laser Med — stimulates the tissue, promotes blood and lymph circulation, and supports skin regeneration.
- Endospheres® Therapy — Microvibration for microcirculation and tissue regeneration, gentle and kind to the veins.
Typical procedure: Vivace® Body stimulates collagen production, Exilis® provides comprehensive treatment, and Icoone® or Endospheres® support the regeneration process — following the Vivace® treatment after a short interval. Which areas and which procedure are best suited to you is part of our Body systems.

Free body consultation + skin check
30 minutes at the clinic. We’ll assess the extent of the sagging and whether it can be treated specifically — and we’ll be honest if another solution is more suitable. No pressure to buy.
Collagen treatment + support
Vivace® Body and Exilis® stimulate the production of new collagen, whilst Icoone® or Endospheres® support the regeneration process. This usually involves several sessions.
Structure + Results
Over the coming months, the skin will build up new collagen — the results will become apparent gradually, so a little patience is required.
Skin tightening using a systematic approach, not a machine.
Specialisation
Focus on pre-ageing, V-NISSG-certified team of women — with a genuine emphasis on skin quality, collagen production and tissue regeneration.
A system rather than a single device
Results come from the interplay — applying stimulation, supporting the tissue — not from a single machine.
Honest advice
We’ll tell you what can be tightened up and what can’t — and whether surgery would be the more honest answer for you. Even if you don’t book anything today.
You might be wondering
Is it really possible to tighten sagging skin without surgery?
For mild to moderate sagging, yes. RF microneedling and radiofrequency stimulate the dermis, prompting the body to produce new collagen and elastin — the skin visibly tightens over a period of months (RF Microneedling Review, Facial Plastic Surgery & Aesthetic Medicine 2022). Where there is a great deal of excess, sagging skin, this method reaches its limits — in such cases, a skin-tightening operation is a more realistic option.
I’m losing weight with Ozempic / a GLP-1 — when should I start?
Ideally, start early and do both at the same time. Rapid weight loss with GLP-1 medicines often happens faster than the skin can retract, leading to sagging on the arms, stomach and thighs (Haykal et al., Journal of Cosmetic Dermatology 2025). We do not prescribe these medicines — we support the skin: if you start stimulating collagen production whilst losing weight or shortly afterwards, you give your skin the best chance of keeping up.
Does it still help after significant weight loss?
For moderate sagging, yes. A case study showed that RF microneedling can improve skin sagging on the thighs following weight loss (Journal of Clinical and Aesthetic Dermatology 2019). In cases of very large amounts of excess skin, for example following significant weight loss, surgery remains the more effective solution — we will assess this together during the consultation.
Loose skin on the tummy after pregnancy — when can I start?
This is very common; the skin has been stretched considerably over a period of months. We can start treatment no earlier than about six months after the birth, and once you have stopped breastfeeding, so that your body and hormone levels have stabilised. At that point, we can specifically stimulate collagen production.
What is the difference between Vivace® Body and Exilis® Body?
Vivace® Body is RF microneedling: fine needles deliver energy with pinpoint accuracy deep into the dermis — the most powerful stimulus for new collagen. Exilis® Body uses radiofrequency and ultrasound to treat large areas from the outside, resulting in firming over a wide area. We often combine the two because they work in different ways.
Does Vivace® Body hurt?
Before the treatment, we apply an anaesthetic cream, which makes it quite bearable. The patented needle technology makes Vivace® more comfortable than many similar devices. Afterwards, the skin may be red for one or two days, similar to a mild sunburn.
How many sessions will I need, and when will I see results?
That depends on the degree of sagging — it usually involves a course of several sessions spaced a few weeks apart. The collagen then builds up slowly: the first changes become apparent after a few weeks, with the full results becoming visible over two to three months or longer.
How much does a treatment for sagging skin cost?
Vivace® Body is priced per treated area; BTL Exilis® Body costs CHF 250 per area; Icoone® and Endospheres® cost CHF 250 each. You can find all prices on the Price list — We’ll discuss the right plan and the number of sessions during the free consultation.

30 minutes at the clinic. CHF 0. We’ll take a look at your skin, give you an honest assessment of whether the sagging can be specifically treated — and you’ll go home with a clear plan. No treatment, no pressure to buy.

Katia, Antonia and Alex are incredibly caring, knowledgeable and professional. You never feel like 'just another customer'."
