FAQ

How does it work?
Renvoir works by creating gentle suction that lifts the skin and tissue upward, opening up space in tight, compressed areas. That lifting action draws fresh blood flow to the spot, which is part of why it can feel looser and more relaxed afterwards. Add in soothing warmth and a calming red glow, and it becomes an easy few-minute ritual for everyday tension.

Who is this designed for?
It's designed for anyone who carries tension in their back, shoulders or neck — whether that's from sitting at a desk, long days on your feet, restless sleep, or just the body feeling stiffer than it used to. It's gentle enough for beginners and adjustable enough for those who like a deeper setting.

Does it actually help with tension?
Most people find it genuinely relaxing and use it as part of a wind-down or recovery routine. It's a wellness and relaxation device rather than a medical treatment, and how it feels varies from person to person — which is exactly why we back it with a 60-day guarantee, so you can try it for yourself with no risk.

How is this different from regular cupping or a massage tool?
Traditional cupping uses fire and glass cups; most massage tools just press down into the muscle. Renvoir does neither — it combines adjustable suction (which lifts rather than presses), soothing warmth and red light in one cordless, flameless device with 12 levels of control, so you get the benefits of cupping without the mess, the risk, or a trip to a clinic.

I've already tried other things for tension. Why try this?
A lot of options either need an appointment, cost money every single time, or are awkward to do on yourself. Renvoir is something you own once and can reach for any evening at home — and because it's genuinely easy and comfortable to use, it's the kind of thing you'll actually keep using.

Does it hurt?
It shouldn't. Start on a low suction level and work up only to what feels comfortable — you control both the suction and the heat the whole time, and the one-touch release lifts it off instantly.

Will it leave marks?
Cupping can leave temporary round marks or redness, especially at higher suction or if you hold it in one spot too long. These usually fade within a few hours to a few days. Lower suction and gliding (rather than holding still) keep any marking lighter.

How do I clean it?
Wipe the cup with a soft, slightly damp cloth after use and let it air dry. Don't submerge the device in water. The included filter cottons keep the suction chamber clean — just swap them as needed.

How long does the battery last?
A full charge gives roughly 3–6 hours of use, so it lasts many sessions between charges. It recharges over USB-C with the included cable.

Is there anyone who should be cautious?
Avoid broken, irritated or sunburned skin, and don't use over varicose veins. If you're pregnant, have a skin condition, take blood thinners, or are managing any medical condition, please check with a healthcare professional before use. Renvoir is a wellness and relaxation device, not a medical treatment.
