Macro close-up of calm, clear skin, the result of lowering stress and cortisol so your skincare can work
€12 once · yours forever · not a subscription

The reason your skincare isn't working is in your nervous system.

The serum, the LED mask, the gua sha, all working on the surface of a problem that starts deeper, with stress and the cortisol it raises. Skin Resonance is sound-based routines that calm your nervous system, paired with the skincare you already do. Twenty minutes, headphones, and your face responds the way the products promised.

The Science

Your skin responds to what's happening inside.

Stress raises cortisol, and cortisol drives breakouts, breaks down collagen, and disrupts the sleep your skin needs to repair. Tension restricts circulation. The result shows up on your face: dullness, breakouts that won't settle, fine lines that seemed to arrive overnight.

Skin Resonance uses sound frequencies to calm the nervous system, so your skin gets the internal conditions it needs to do its own repair work.

Each of these connections is supported by peer-reviewed research, the International Journal of Stress Management, JMIR Mental Health, MDPI Dermatology Reports and others.

This isn’t a bare tone generator. The binaural beats and solfeggio tones are generated in real time by the same engine as the app, with a tuned brown-noise bed, per-frequency filtering and smooth fades in and out. Pause, resume and step changes are click-free, which most browser audio apps can’t say, so you can lie down with your eyes closed and never be jolted by a digital artefact.

Grounded in published research

We're careful about what we claim, and transparent about the evidence.

Our approach draws on peer-reviewed studies covering sound, stress, sleep and skin. We don't claim a specific frequency fixes a specific skin problem. We do claim that calming the nervous system creates better internal conditions for the skin you're already caring for.

The founder

Built by a composer who felt it work first-hand.

Skin Resonance was created by Sophie Kazandjian, a piano composer and mother of three, after she found that certain frequencies, including the Schumann resonance, eased her migraines and calmed her before sleep. When her skin started responding too, she built the routines she wished existed: careful, evidence-transparent, and designed to sit quietly alongside the skincare you already trust.

Made in Saint-Quentin-la-Poterie, France. Read Sophie's full story →
