Our tape features a small center breathing hole to allow limited airflow if needed, offering peace of mind in case of temporary congestion. The body’s natural protective reflexes will wake you if breathing becomes uncomfortable.

Made with a gentle adhesive, oi tape™ is easy to remove at any time and creates a light seal, never a rigid hold.

For added comfort, we recommend trying the tape while awake before overnight use. If you have sleep apnea, significant breathing concerns, or a medical condition, consult your healthcare provider before use.

oi tape™ gently encourages lips to stay closed during sleep, helping promote nasal breathing instead of mouth breathing.

Here’s how it works:

Mouth breathing at night allows the jaw to fully relax, which can contribute to a softer, less defined appearance. By keeping the lips closed, oi tape™ helps maintain a more supported jaw position, encouraging healthier muscle engagement over time.

Nasal breathing naturally filters and humidifies the air you breathe, supporting better oxygen delivery throughout the body. Improved oxygen flow during sleep helps support the skin’s overnight renewal process, contributing to a fresher, more radiant look by morning.

Breathing through the nose also supports circulation and the body’s natural repair rhythms while helping reduce fluid retention and morning puffiness.

By changing how you breathe while you sleep, oi tape™ works with your body’s natural overnight restoration, so you can wake up looking more sculpted, refreshed, and glowing.

Most customers begin noticing subtle changes within the first 3–5 nights of consistent use, often including reduced morning puffiness and a more refreshed appearance.

With continued nightly use, more visible jawline definition may develop over the next 2–3 weeks, as breathing habits and facial muscle engagement begin to shift. By around 30 days, many users report a more sculpted look, improved facial contours, and a noticeably better morning appearance.

Results vary based on individual factors such as:

• Natural sleep breathing patterns
  
• Consistency of nightly use
  
• Age and skin elasticity
  
• Hydration and overall wellness
  

For best results, we recommend using oi tape™ nightly. Many customers find that benefits continue to improve over 2–3 months as the body fully adapts to nasal breathing during sleep.

And if you’re not seeing noticeable changes within 30 days, our money-back guarantee has you covered.

Many people with allergies find that mouth taping feels more comfortable over time. Nasal breathing naturally filters and humidifies the air, which may help reduce irritation during sleep.

If you experience temporary congestion, the small breathing hole allows for gentle airflow while your body adjusts. On nights when congestion feels too heavy, it’s best to skip mouth taping and resume once breathing feels clear again.

Many customers choose to use oi tape™ alongside their CPAP therapy. Some find it complements their routine by encouraging consistent nasal breathing during sleep.

If you have sleep apnea or use a CPAP, we recommend checking with your sleep specialist before introducing any changes to your nighttime routine.

It depends on the type of sleep apnea. If you have obstructive sleep apnea (OSA), it’s important to speak with your healthcare provider first. Mouth taping is not a replacement for medical treatment.

That said, some people with mild sleep apnea or those already using a CPAP choose to incorporate mouth taping into their routine. By helping reduce mouth air leaks and encouraging nasal breathing, oi tape™ may complement CPAP use for some individuals.

As always, any changes to your sleep routine should be discussed with your sleep specialist to ensure they’re appropriate for you.

Regular tape, such as medical or household tape, is not designed for overnight use on the face and may cause irritation, skin damage, or discomfort. It can also be difficult to remove and may interfere with comfortable breathing during sleep.

oi tape™ is made with a gentle, non-toxic, medical-grade adhesive specifically designed for delicate facial skin. Each strip includes a small safety breathing hole, uses a carefully balanced level of adhesion, and is shaped to comfortably fit the lips.

Unlike standard tapes, oi tape™ is designed for nightly use and easy removal, without harsh residue on sensitive skin.

Our guarantee is simple: try oi tape™ for 30 full nights. If you’re not satisfied with your experience, return any unused strips for a full refund—no questions asked.

Once your return is received, refunds are processed within 2–3 business days.

We’re able to offer this guarantee because the vast majority of customers who try oi tape™ choose to reorder. We’re confident you’ll love how it fits into your nightly routine.
