Frequently Asked Questions

Everything you need to feel confident before your first reset.

Using Your Tape

How do I apply the tape correctly?

Start with clean, dry lips and the skin around your mouth. Avoid applying lip balm or moisturiser beforehand, even a small amount of moisture can affect how well the tape holds.

Place the strip gently across your lips without stretching it. Press firmly along the full edge for around 10 seconds and let the adhesive settle. It should feel comfortable and secure, not tight.

If you're new to mouth tape, try it during a short nap or your evening wind-down before using it overnight.

The tape isn't staying on overnight. What should I try?

This is almost always a moisture issue and it's an easy fix.

Make sure your lips are completely clean and dry before applying. No lip balm, no moisturiser, no water. Press along the full edge firmly for 10 seconds before sleep and let the adhesive settle properly.

If you're still finding it isn't holding, reach out. We'll make it right.

How does the tape feel to remove in the morning?

Gently. The adhesive is designed to be skin-safe and easy to remove without pulling or discomfort.

Peel slowly from one corner. There's no need to rush. If it feels like it's catching, dampen the edge slightly and it will release easily.

Can I use it every night?

Yes. Deep Sleep tape is designed for consistent nightly use. The adhesive is breathable, gentle, and suitable for sensitive skin.

Replace each strip after a single use for best comfort and hygiene. If any irritation occurs, discontinue use and reach out to us.

Will it work if I have a beard?

Yes. Deep Sleep tape features an inclusive beard-safe design. The strip is applied across the lips rather than the surrounding skin, so facial hair doesn't affect how it works or how it holds.


What if the strip feels too tight or claustrophobic? This is completely normal, especially in the first few nights. Try the fold-and-cut method: fold the strip in half lengthwise, then cut a small triangle from the centre fold. The small opening this creates allows natural airflow and removes the sensation of restriction without affecting how the strip works overnight. Most people find they no longer need the modification after the first week, but it is there whenever you need it. If at any point you feel uncomfortable or find it difficult to breathe through your nose, remove the strip immediately.
How many nights a week do I need to use it? You do not need to use it every single night to notice a difference. Starting with three nights in your first week is enough for your body to begin responding to the signal. Rest does not require perfection — building a gentle, consistent habit over time matters more than nightly use.
What if I have too many strips building up? If you are travelling, in a busy season, or simply not getting through your strips, you can login to your account and pause your subscription for up to 3 months and resume whenever you are ready. OR email us at care@whyslp.com and we will sort it immediately. No questions, no hassle.

The Product

What is the collagen infusion for?

Each strip is infused with collagen to support overnight lip hydration. Whilst the tape encourages calm, closed-mouth rest, the collagen works quietly in the background, so you wake up with softer, more nourished lips rather than the dry, uncomfortable feeling that often comes with mouth breathing overnight.

It's a considered detail. Rest and hydration, at the same time.

What's included in each pack?

Each pack contains 30 collagen-infused mouth tape strips, a one-month supply, in a resealable pouch designed to keep strips fresh and easy to store or travel with.

What makes WHYSLP different to other mouth tapes?

Most mouth tapes are purely functional. WHYSLP is designed as a considered sleep signal, with a medical-grade adhesive selected for skin safety, collagen infusion for overnight hydration, and a beard-safe fit designed for every sleeper.

It's not just about keeping your mouth closed. It's about giving your body a small, deliberate cue that the day is finished and rest can begin.

Safety

Is mouth taping safe?

Yes, when used correctly. Deep Sleep tape is dermatologist-tested and designed with a gentle, skin-safe adhesive for nightly wear.

As with any new product, we recommend speaking with your healthcare provider before use if you have any concerns about your breathing, sleep, or skin.

Who should not use mouth tape?

Please avoid use if you:

  • Have diagnosed sleep apnoea or a known nasal or airway obstruction
  • Experience ongoing nasal congestion, sinus issues, or breathing difficulties
  • Have medical conditions that affect breathing during sleep
  • Have known sensitivities or reactions to adhesives

Not sure if it's right for you? Check with your healthcare provider before use.

I'm noticing skin sensitivity or irritation. What should I do?

Please stop using the tape straight away.

Your comfort and safety always come first. Deep Sleep tape is dermatologist-tested and designed to be skin-safe, but everyone's skin is different. If something doesn't feel right, we want to know.

We offer a full refund, no questions asked. Reach out with your order number and we'll take care of it promptly.

Can I use it if I'm pregnant?

We recommend speaking with your healthcare provider or midwife before use during pregnancy. Your rest matters deeply, and so does doing this safely with the right guidance for your situation.
