The Stella Center

Our dear Rosa Sigrist led an international multicenter study on Doppler findings in vascular occlusion.
The manuscript is now available as a preprint while awaiting peer review.
Grateful to be part of this collaboration and looking forward to the final publication.

Do you know what is under your patient’s skin surface?

Can you avoid the blood vessels? Can you dissolve old filler and treat other complications?

Next ultrasound training - July 2026. Most of my training courses are now private, do this is the only one for the year. We do one- and two-day courses.

Hope to see you there!

This is what healed scars from a facelift are supposed to look like. I take my time so it could look like this.

IMCAS 2026 in Paris is coming!
I’m excited to see my friends and colleagues, learn and teach.
I’ll be presenting several topics at the Thinkin pre-meeting, then Ultrasonography summit, and then the main meeting. Join me to explore the future of aesthetic medicine and aesthetic ultrasound!

Is this toxin resistance?

Same masseter muscle.
Different tissue.

Long-term (Bo)tox can change muscle architecture, replacing contractile fibers with denser, fibrotic tissue.
If the tissue is different, should it really be treated the same way?

Let me know what you think.

So… is filler good or bad?

The answer isn’t as simple as it’s often made out to be.

As many of you know, I run an ultrasound-based complications clinic and regularly see the full spectrum of aesthetic outcomes. I also see the issues with fillers. In most cases, the true problem isn’t the filler itself, but the placement or amount.

Occasionally, changes in structure over time can create issues as well. And every once in a while an inflammatory response or infection is to blame.

Here’s an example where we removed AND added filler for optimal outcome.

This patient came in with persistent under-eye puffiness from filler placed elsewhere. Using ultrasound, we identified the issue and were able to treat it in a single session. One session isn’t always enough, but in this case, it was.

Once the tissue settled, the puffiness resolved, and she didn’t need any refill in that area. Subtle, restrained treatment of the chin and lips improved her overall facial balance.

Before anyone puts words in my mouth:

I stand by my belief that filler is not the villain.
Overfilling and poor technique are.
And with the right approach, most of these issues can be fixed.
