Everything you need to know.

A web app of guided sound routines, built on binaural beats with solfeggio tones as the carrier, designed to calm your nervous system alongside the skincare you already do. It is a one-time €12 purchase with lifetime access, and it works on phone, tablet and desktop.

Yes, that is exactly what Skin Resonance is. Rather than a general relaxation app, it is built specifically around skin, using binaural beats and solfeggio tones to support the low-stress, deep-sleep states that research links to healthier skin.

Sound does not touch the skin directly. It works indirectly: certain frequencies help lower stress markers such as cortisol and support deeper sleep, and both reduced stress and better sleep are linked in peer-reviewed research to less inflammation and better skin repair.

The evidence is about the conditions your skin needs, not a direct cure. Frequencies can reduce stress and support sleep; lower stress and better sleep are associated with healthier skin. We do not claim a specific frequency fixes a specific skin problem.

Both are sounds with a job in a routine. Binaural beats play a slightly different tone in each ear, and the brain hears a slow beat between them, named for the brain rhythm it sits in: delta for deep sleep, theta for the edge of sleep, alpha for relaxed attention. They need headphones; on speakers the app plays them as pulsed tones. Solfeggio tones are single steady tones from a sound-healing tradition, each with a traditional meaning, such as 396 Hz for grounding and 528 Hz for restoration, and they sound the same on any speaker. In the research, binaural beats have trial evidence for easing anxiety and helping sleep; the solfeggio tones are earlier, with two small studies on 528 Hz, and the app uses them because they are restful to listen to. Every sound in the app and what it is used for is on The science.

It rests on three researched links: sound frequencies can reduce stress markers, stress hormones affect the skin, and deep sleep drives skin repair. Each link is supported by published studies, set out on our Science page, and how we read a study explains the standard every evidence section is held to.

No. Skin Resonance is not a medical device and does not diagnose, treat, cure or prevent any condition. If you have a diagnosed skin condition, please see a dermatologist. If you have epilepsy or a seizure disorder, consult a professional before using audio stimulation.

General meditation apps are built for the mind. Skin Resonance is built around skin: routines are organised by skin concern, can be layered with the skincare tools you own, and use a validated audio engine tuned specifically for this purpose.

No. Rife programmes come from 1930s claims that tuned frequencies can destroy microbes, which have never been reproduced, and his original device was electrical rather than audio. PEMF (pulsed electromagnetic field therapy) uses coils that generate a magnetic field; some devices are medically cleared for slow-healing fractures, but a phone or headphones cannot produce that field. 432 Hz and 528 Hz tracks are music tuned to those pitches, pleasant to rest to. Skin Resonance works through sound alone and makes a narrower claim: binaural beats, which have trial evidence for reducing anxiety, and guided slow breathing, used to settle the stress response that affects skin. The solfeggio tones are there because they are restful to listen to. The ideas behind each are compared in sound healing at home: what the research supports.

Fourteen: slow breathing, tired and dull skin, stress breakouts, puffiness, cellular restoration, pre-event glow, post-treatment recovery, tension and tightness, period week, perimenopause and menopause, ageing and elasticity, hormonal balance support, seasonal change and post-travel recovery.

Stress raises cortisol, which is linked to inflammation and excess oil. By supporting nervous-system calm and lower cortisol, the stress-breakout routine helps create the internal conditions for skin to settle. It complements, and does not replace, your usual skincare.

Deep, slow-wave sleep is when much of the body’s repair happens. Several routines are designed to support deeper sleep, which research links to better barrier recovery and skin appearance.

There are dedicated perimenopause and menopause routines with longer sessions focused on sleep, calm and collagen support during hormonal changes. It supports the conditions for healthier skin; it is not a hormone treatment.

Five optional ambient beds, rain, ocean, forest, fire and stream, that you can layer under any routine to deepen the sense of calm.

The Build tab lists every sound in the app, 22 of them in four groups (binaural beats, focus beats, solfeggio tones and rest), each with a line on what it does. Tap the ones you want, set the minutes for each, from one to sixty, drag them into order, choose a soundscape and a sleep-friendly ending if you like, then name the routine and start it or save it to the Saved tab. Up to ten steps.

Yes. After each session you can add a note on how you felt, building a session log over time, and you can print any routine for offline reference.

Headphones are best, because binaural beats only work when each ear hears a slightly different tone. If you would rather listen out loud, choose Speakers in the app and the binaural steps play as pulsed tones instead, an alternative rather than the same effect. Solfeggio tones and soundscapes sound the same either way. The With skincare level also lets you time any tools you already own.

Yes, this is a core feature. The With skincare level builds a routine around red light and LED devices, at-home lasers, microcurrent and radiofrequency, gua sha, rollers, masks and your evening products, and tells you when to use each during the session.

The free taster is 10 minutes. Slow breathing runs five, ten or twenty minutes, the thirteen concern routines run from 35 to 70 minutes including their silent rests, and a routine you build yourself can be any length, each step from one to sixty minutes.

Sound only uses frequencies alone, with no tools or products needed. With skincare builds the same routine around the tools and products you own, prompting you when to use each one.

Yes, that is the intention. It is designed to sit quietly alongside the products and tools you already trust, supporting the internal calm your skin needs to make the most of them.

On phone, tablet and desktop, in any modern browser. Once installed to your home screen it behaves like a native app and runs offline, generating the audio locally.

€12 (about £10) as a one-time purchase, with lifetime access to all 14 routines, the custom builder and every future update. It is not a subscription, and there are no recurring fees.

Yes. Payment is handled entirely by Stripe on their own secure checkout page. Your card details never touch Skin Resonance.

No. There’s nothing to register for and no password to remember. After you buy, you get a private access link by email.

No. There are no ads, no tracking and no analytics that identify you. Nothing about you is stored or sent anywhere, and any session notes stay on your own device.

Low enough that you could still hear someone speak to you across the room. The routines are quiet by design and there is nothing to gain from turning them up; start the volume at a quarter and leave it there. For reference, the World Health Organization and the International Telecommunication Union set the weekly sound allowance for adults at 80 decibels for 40 hours, and at 75 decibels for children, which a quiet routine at a comfortable level sits well inside.

A routine of 35 to 70 minutes at a comfortable volume is well within the weekly allowance above, and the stress and sleep trials used twenty to ninety minutes a day. The players stop when a routine ends. Take the headphones out when it finishes rather than leaving them in overnight, and give your ears quiet time between sessions, as you would with any headphone listening.

Not the rest routines, and never while driving or using machinery: binaural beats in the theta and delta range are made for lying down with your eyes closed, and the whole point of them is to make you drowsy. The focus beats in Build your own, from 14 to 40 Hz, are the exception and are meant for a desk. Solfeggio tones and the soundscapes are fine as background sound for quiet tasks.

If you have epilepsy or a seizure disorder, tinnitus, hyperacusis or any diagnosed hearing condition, or you are pregnant, ask the doctor, midwife or audiologist who looks after you before adding audio stimulation, as you would with any new wellness practice. The trials behind the app were run on adults without these conditions, so there is no evidence either way. If you wear hearing aids, use the Speakers setting rather than headphones.

It is built for adults, and the research behind it was done on adults. The soundscapes and the slow-breathing routine are gentle enough for anyone to listen to at a low volume with an adult present; the binaural routines are not designed for children, and there is no reason for a child to use them. The children’s allowance in the WHO standard is 75 decibels over a week, which is lower than the adult figure.

Stop. A small number of people find the pulse of a binaural beat unpleasant or faintly dizzying, usually at too high a volume. Turn the volume down first; if that does not settle it, switch to Speakers in the app, which plays the beats as pulsed tones, or choose a solfeggio step or the breathing routine, which have no beat. Nothing in the app needs to be endured, and the skin side runs through rest, not through tolerating a sound.
