Nose Strips vs Nasal Dilators: Which Works Better?
Both products support the narrow front section of the nasal airway, but they work from opposite directions. Nose strips lift the nose externally, while internal nasal dilators sit inside the nostrils and support them from within.
External Nose Strip
Adhesive support applied across the outside of the nose.
Internal Nasal Dilator
A device positioned inside the nostrils.
Are nose strips or internal nasal dilators better?
Neither is best for everyone. Nose strips are usually easier for first-time users, do not enter the nostrils and are convenient for sleep and sport. Internal nasal dilators are often reusable and avoid facial adhesive, but some people dislike the feeling of a device inside the nose. Research suggests both can improve nasal patency, while particular internal devices have outperformed particular strips in some direct comparisons.
The key differences
External vs internal
Nose strips pull the flexible nasal walls outward. Internal dilators hold the nostrils open from within.
Comfort is personal
Some people prefer no internal contact, while others prefer avoiding facial adhesive.
Neither treats sleep apnoea
Both may improve nasal breathing but are not standalone treatments for obstructive sleep apnoea.
Nose strips vs internal nasal dilators comparison
| Feature | External nose strips | Internal nasal dilators |
|---|---|---|
| Position | Across the outside of the nose. | Inside the nostrils. |
| Action | Flexible bands lift the sidewalls outward. | Loops, cones or stents support the nostrils internally. |
| First use | Usually simple. | May require sizing and adjustment. |
| Adhesive | Yes for traditional strips. | Usually no. |
| Reusable | Usually single-use. | Many are reusable. |
| Skin sensitivity | Adhesive may irritate sensitive skin. | Avoids facial adhesive. |
| Nostril sensitivity | No internal contact. | May cause pressure or rubbing. |
| Sleep | Easy external overnight support. | Effective when the size remains comfortable and secure. |
| Sport | Convenient, but sweat can weaken adhesion. | No adhesive, but fit and movement matter. |
| Cleaning | No cleaning after single use. | Reusable devices require washing and drying. |
| Best suited to | People who dislike objects inside the nose. | People who dislike adhesive or want reusable support. |
How do they work?
How nose strips work
Traditional adhesive nose strips contain flexible bands. Once applied across the lower bridge, the bands create outward tension that may support the nasal sidewalls and increase space near the nasal valve.
- Nothing sits inside the nostrils.
- Easy to apply and remove.
- Available for sleep and sport.
- Flat and easy to travel with.
How internal dilators work
Internal devices use loops, wings, cones or connected stents to support the nasal entrance from within. Their effectiveness and comfort depend heavily on design and sizing.
- Many are reusable.
- No facial adhesive.
- May provide strong direct support.
- Requires cleaning and correct sizing.
What does the research say?
Research generally indicates that both external and internal nasal dilators can improve nasal patency for some users. Direct comparisons have found that certain internal devices can produce larger changes in peak nasal inspiratory flow than certain external strips, but this does not mean every internal product is better than every nose strip.
A study comparing internal Max-Air Nose Cones with external Breathe Right strips reported a stronger peak-flow effect from the internal device tested. Another study involving people who snored found improvements with an internal dilator and a participant preference for that device over an external strip.
These findings must be interpreted carefully. Device shape, firmness, size, anatomy and comfort all affect outcomes. A device that creates a large measured opening is not useful if it causes pressure, falls out or disrupts sleep.
| Question | Evidence | Limitation |
|---|---|---|
| Can both improve nasal breathing? | Yes, both may improve nasal patency. | Response varies by anatomy and product. |
| Can internal devices be stronger? | Some direct studies favour particular internal devices. | Not generalisable to all brands. |
| Can either reduce snoring? | Some selected users report or demonstrate improvement. | Snoring may originate outside the nose. |
| Can either treat sleep apnoea? | No reliable overall OSA benefit has been established. | Do not replace prescribed therapy. |
| Can either improve sports performance? | They may improve nasal openness or comfort. | No consistent VO₂ max or performance gain. |
Which is better for sleep and snoring?
Choose a nose strip when
You want simple external support and do not want anything placed inside your nose.
Choose an internal dilator when
You want reusable, adhesive-free support and tolerate a device inside the nostrils.
Fit matters most
A poorly fitted internal device or incorrectly positioned strip may provide little benefit and disturb sleep.
Either format may reduce snoring when nasal resistance contributes. Neither addresses every cause of snoring, including vibration or narrowing around the tongue, soft palate or throat.
Which is better for running and sport?
Nose strips are popular for running, cycling, football, rugby, HYROX and gym training because they are easy to apply and do not create pressure inside the nostrils. Internal dilators avoid adhesive and may remain effective when the skin becomes sweaty, but they need a secure fit.
Nose-strip advantages
- No device moving inside the nose.
- Easy removal after training.
- Sport-focused adhesive options.
- Comfortable during forceful breathing for many users.
Internal-dilator advantages
- No adhesive affected by facial oil.
- Reusable designs may cost less over time.
- Often less visible from a distance.
- Direct internal support.
Both may make nasal breathing feel less restricted, but current research does not consistently show improved VO₂ max, speed, heart rate or endurance in healthy athletes.
Which is more comfortable?
| Concern | Suggested starting point | Reason |
|---|---|---|
| I hate objects inside my nose | Nose strip | All support remains external. |
| Adhesive irritates my skin | Internal dilator | No facial adhesive is usually required. |
| My nostrils are sensitive | Nose strip | Avoids internal pressure and rubbing. |
| I sweat heavily | Internal dilator or sport-grade strip | Sweat can weaken standard adhesive. |
| I move a lot during sleep | Depends on fit | A secure strip or correctly sized device may work. |
Which costs less over time?
Internal dilators are often reusable, which may reduce cost per use. Traditional adhesive strips are single-use, but many users prefer the convenience and hygiene of applying a fresh strip without cleaning a device.
Magnetic external systems sit between the two formats: they use a reusable bridge with fresh adhesive side tabs. Read Magnetic vs Adhesive Nose Strips.
Which is better for a deviated septum?
Neither option can straighten or permanently correct a deviated septum. Both may temporarily support airflow when narrowing around the nasal valve contributes to obstruction. The location and severity of the deviation determine whether either product helps.

Can you wear both together?
It is possible to combine external and internal support, but most people do not need both. Test each product separately first. Stop if combined use creates excessive pressure, skin irritation, dryness, pain or nosebleeds.

Our recommendation
For most first-time users, an external nose strip is the easiest place to start. It requires no internal fitting, can be removed immediately and makes it simple to judge whether nasal-valve support changes how breathing feels.
An internal dilator may be the better choice when you dislike adhesive, want a reusable device or find that a well-fitted internal product provides stronger support without discomfort.
Final verdict
Nose strips and internal nasal dilators share the same broad purpose: supporting the narrow front section of the nasal airway. Choose nose strips for simple external use and no inside-nose sensation. Choose an internal dilator when reusable, adhesive-free support matters more and you tolerate the internal fit.
Neither treats allergies, permanently corrects structural obstruction or replaces assessment for persistent blockage, heavy snoring or suspected sleep apnoea.
