How It Works
Cupping 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.

Common FAQs

Does it actually work?

Renvoir brings together three things in one device — adjustable suction, gentle warming heat, and a soothing red light — to help relax muscles and ease everyday tension. It's a wellness and recovery tool rather than a medical treatment, and how it feels varies from person to person. Most people use it as part of a wind-down or post-workout routine.

Does it hurt?

It shouldn't. Cupping can feel unusual at first, but most people find it relaxing. Start on a low suction level (1–4) and work up only to what feels good. You're in control of suction and heat the whole time, and the release button lifts it off instantly.

Will it leave bruises or marks?

It can leave temporary redness or round marks, especially at higher suction or if you hold it in one spot too long. This is normal with cupping and usually fades within a few hours to a few days. Lower suction, and gliding with a little oil instead of staying put, will reduce it.

Is it safe for beginners? Do I need a professional's help?

Yes — the 12 adjustable levels and 20-minute auto-shutoff make it easy to ease in on your own, no professional needed. Avoid broken or irritated skin, and as a general precaution anyone considering cupping should check with a healthcare professional first, especially if pregnant or managing a medical condition.

"My frozen shoulder had made everyday things like getting dressed and doing my hair so uncomfortable. After using Renvoir consistently, my shoulder started feeling looser and much easier to move. I'm finally able to reach higher without the zingers."

Why It Works

It Lifts, It Doesn't Press

Cupping 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.

Targets The Right Spots

Good To Know

Frequently Asked Questions

How often can I use it?
Most people use it for a few minutes per area, a few times a week, as part of a wind-down routine. Start gently and see what feels good for you. Give an area a rest between sessions rather than working the same spot repeatedly.
Can I use it with oil or lotion?
Yes — a little body oil or lotion helps the cup glide smoothly across the skin, which is ideal for moving along the back and shoulders. To hold it in one spot instead, you can use it on clean, dry skin.
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 replacement filter cottons keep the suction chamber clean — 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.
Will it leave marks?
Cupping can leave temporary round marks or redness that usually fade within a few hours to a few days. Lower suction and gliding (rather than holding still) keep marking lighter.
Who should be cautious about using it?
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, check with a healthcare professional before use. Renvoir is a wellness and relaxation device, not a medical treatment.
