About us

Cutaneous was founded by doctors in aesthetic medicine, dermatology and radiology. We realised that combining our knowledge and experience would lead to better diagnoses as wel as safer and more effective treatments of our patients.

Our combined knowledge and experience has lead to strong synergy that we want to share with colleagues worldwide. That is the reason we founded Cutaneous.


Cutaneous is founded in 2019 by Dr. Peter Velthuis and Dr. Leonie Schelke. Our vision is to enhance your professional development in cosmetic treatment by deploying ultrasound in your daily practice. We have launched a series facial anatomy i.c.w. ultrasound courses around the globe. Online and Hands-on. We call it the Safe & Sound Learning Experience. ​


We are committed to teach dermatologists, aesthetic physicians and plastic surgeons the use of ultrasound and facial anatomy. To empower you to raise the bar in quality and safety for ultrasound guided injections. It is our mission to prevent complications in aesthetic dermatology.
