Sophie Kazandjian, composer and founder of Skin Resonance, smiling in warm natural light The founder

A composer who felt it work first-hand.

Skin Resonance was created by Sophie Kazandjian, a piano composer in her late forties with three young children, the youngest four. She first came to frequencies for herself: certain tones, including the Schumann resonance, eased her migraines and helped her settle before sleep.

When her skin began to respond too, calmer, clearer, less reactive in the weeks she slept well, she started building the tool she wished existed. A full-time freelancer with three children has no spare hour for long routines or expensive treatments. Whatever helped her skin had to fit inside rest she was taking anyway: something careful and evidence-transparent, sitting quietly alongside the simple skincare she already trusted rather than replacing it.

The composing came first. Sophie writes quiet, cinematic solo piano, played by ear, with two records released and a third on the way. You can listen at sophiesmusic.com. Building routines from sound was less a leap than a return to material she already knew.

Why it's built the way it is

Evidence, transparently

The app never claims a frequency cures a skin condition. Where research is strong we say so; where it is preliminary, we say that too. The Science page cites every source.

Alongside, never instead

Skin Resonance is designed to work with the products, tools and professional care you already use, not to replace any of them.

Made in the south of France

Skin Resonance is made in Saint-Quentin-la-Poterie by Sophie Kazandjian EI, trading as Sophie's Bureau. It is a small, independent, self-funded project, made by one person with care, which is why it is a single, one-time €12 purchase rather than a subscription.
