The purpose
Its whole purpose: better breathing
No medication, no trick. The strip gently lifts the sides of the nose, allowing more air to pass through the nose at night.
Well thought out
Built with intention
Henkel adhesive, sweat-proof and adapted for sensitive skin, combined with flexible splints that lift the nostrils instead of just resting on them.
How do I apply it
One strip, one handle
Dry the bridge of the nose, apply the strip to the center, press gently. In the morning, it slowly detaches without leaving any residue. No readjusting, no learning. One pack lasts you for 30 nights.

Do you have questions?
We have answers
Everything you need to know before you start. And if your question isn't here, we're just a message away.
Can I use the strips on sensitive skin?
The adhesive is hypoallergenic and suitable for sensitive skin. Do not use if the skin on your nose is irritated or injured.
Can I reuse a strip?
No, each strip is intended for one night. The package contains 30 pieces.
Does it detach at night?
The adhesive is sweat-resistant and holds during movement. It is important that the bridge of the nose is dry when applying it.
Does peeling it off hurt?
In the morning, slowly and carefully peel off from one side, preferably after showering when the skin is warm.
What differentiates them from simple nasal strips?
The spring action of the temples. They actively lift the nostrils instead of just resting on the nose.
