One of the most common questions in my practice: "How long does the result last?" The answer is more nuanced than the often-quoted "6–12 months" — and current research reveals some surprising findings.
What the research shows
For a long time, it was assumed that hyaluronic acid fillers break down completely after 6–12 months. However, more recent MRI studies paint a more differentiated picture: in some tissue areas, hyaluronic acid can still be detected years after injection.
This does not mean that the visible result lasts that long — but it does explain why many patients report that top-ups require less product over time.
Factors that influence longevity
1. Treatment area
Areas with a lot of movement (lips, nasolabial folds) break down filler faster than more static zones (cheeks, temples). The lips are the most "demanding" area — a touch-up after 6–9 months is perfectly normal here.
2. Product choice
Not all hyaluronic acid fillers are the same. The cross-linking technology significantly determines the longevity. More highly cross-linked products last longer, but they are also firmer and not suitable for every area.
3. Metabolism
I have patients who run five times a week and come back for top-ups every four months. And others who get a single session and it lasts a full year. Metabolism, exercise, sauna — it all plays a role, but ultimately it is very individual.
4. Technique and volume
The injection technique and the amount used play an important role. "Less is more" sometimes also means shorter longevity — but more natural results.
Realistic expectations
Here is my honest assessment based on my clinical experience:
- Lips: 6–9 months of visible result
- Nasolabial folds: 9–12 months
- Cheeks/midface: 12–18 months
- Jawline/chin: 12–18 months
- Tear trough: 12–24 months
The cumulative effect
What many people do not realise: with regular top-ups, a "baseline" builds up. After 2–3 years of consistent treatment, most patients need less product and longer intervals between appointments.
My advice
Do not be misled by claims like "lasts 2 years". Longevity is individual and depends on many factors. By the way: if you are wondering whether Profhilo or a traditional hyaluronic acid filler is better suited for you, our comparison Profhilo vs. hyaluronic acid filler may help. What matters more than maximum longevity is a natural result that you feel good about.
Plan for top-ups from the start — they are part of the treatment. This way, we can maintain the result optimally and adjust as needed.
