Mouth tape basics
What is mouth tape?
Mouth tape is a small adhesive strip worn over the lips during sleep to keep the mouth closed, so you breathe through your nose. Most are made of skin-safe fabric or silicone tape, and some have a slit or vent in the middle. There are no official guidelines for using it [9].
What does mouth tape do?
Mechanically, it holds your lips together overnight. Claims that this improves sleep, breath or jawline come mostly from social media, and a 2025 systematic review found only a few small studies with mixed results [1]. A collagen mouth tape such as pretty sleepy. adds a hydrating gel, so it also works as an overnight lip treatment.
Why do people tape their mouths at night?
Most try it because they wake up with their mouth open or have seen it on TikTok. A 2025 review of TikTok videos found the most common claimed benefits were better sleep and oral health, most of which haven't been tested [2]. Some people simply like waking with their lips closed and less dried out.
What is collagen mouth tape?
Collagen mouth tape is a mouth strip with a gel layer, containing collagen and hyaluronic acid, on the side that touches your lips. It keeps your lips gently closed overnight like ordinary mouth tape while the gel acts as an overnight lip mask. pretty sleepy.'s version has a soft black stretch-fabric outer printed with periwinkle stars and a breathing vent in the centre.
Is collagen mouth tape worth it?
It depends on what you want. If you only want your lips held closed, plain tape is cheaper; if you also use a lip mask at night, a collagen tape does both jobs. Hydrolysed collagen and hyaluronic acid are established skincare moisturisers [8][7], but no study has tested collagen mouth tape itself, so judge it by how your lips look and feel after a few weeks.
How is mouth tape different from an overnight lip mask?
A lip mask is a balm or gel you leave on overnight: it moisturises but doesn't keep your mouth closed and can rub off on the pillow. Plain mouth tape keeps your lips closed but does nothing for the skin. Collagen mouth tape combines the two, with the gel held in place by the strip.
Does the collagen in mouth tape actually do anything?
On skin, collagen works at the surface: hydrolysed collagen is a moisturiser that helps the outer layer of skin hold water [8]. It doesn't add collagen to your lips or replace the collagen your body makes. Expect softer, more hydrated-looking lips, not structural change.
Safety
Is mouth taping safe?
For a healthy adult who breathes easily through the nose, the side effects most often reported are skin irritation, discomfort and anxiety [10]. It isn't safe for everyone: a 2025 systematic review warned of a potentially serious risk of harm for people who tape indiscriminately, and of asphyxiation risk when the nose is blocked [1]. Try it while awake first, and talk to your doctor if you snore loudly or have a breathing condition.
Is mouth taping dangerous?
It can be for some people. If your nose is blocked, sealing your mouth restricts your only airway, and studies in the 2025 review raised the risk of asphyxiation in the presence of nasal obstruction [1]. Australian sleep physician Dr Chris Seton (Woolcock Institute) has warned that taping can worsen breathing problems in people with sleep apnoea [11].
Can mouth taping kill you?
Researchers flag a risk of asphyxiation if your nose is blocked while your mouth is taped [1]. That is why mouth tape should never be used with a cold or congestion, after heavy drinking, if you might vomit in your sleep, or on children [9]. A vent and an easy-peel edge reduce the sealed feeling, but they don't make mouth tape safe for a blocked nose.
Who should not use mouth tape?
Skip it if your nose is blocked (cold, allergies, deviated septum), if you have untreated sleep apnoea, if you have asthma or COPD without medical advice, if you have anxiety or panic disorder, or if you might vomit during sleep, and never use it on children [9][10]. Skip it after heavy drinking too. If you snore loudly, gasp or stop breathing in your sleep, see a GP first.
Do doctors and dentists recommend mouth taping?
Not as a routine practice. Sleep and ENT specialists say the evidence is thin and want anyone who snores or might have sleep apnoea assessed first [1][11]. Some dental and breathing clinics publish how-to guides for patients who mouth-breathe by habit, but there is no clinical guideline [9].
Can I use mouth tape with a blocked nose or a cold?
No. Mouth tape is only for people who can breathe comfortably through the nose, so skip it whenever you're congested [9][10].
Can children use mouth tape?
Not without a doctor's supervision: the Sleep Foundation advises against mouth taping children unless it is medically supervised [9]. A child who breathes through the mouth at night should see a GP, since problems such as enlarged tonsils make taping unsafe [10]. pretty sleepy. is made for adults only.
Can I mouth tape while pregnant?
There's no research on mouth taping in pregnancy. Don't use it if your nose is stuffy [9], and ask your GP or midwife first, particularly if you've started snoring.
Can I use mouth tape with sleep apnoea or a CPAP machine?
Only if your sleep physician suggests it. Two small studies found improvements in mild sleep apnoea [3][4], but a 2025 systematic review judged the evidence insufficient and flagged risks [1]. Mouth tape is not a replacement for prescribed treatment such as CPAP, and pretty sleepy. is not intended for sleep apnoea.
Can I still breathe if I need to?
pretty sleepy. has a breathing vent in the centre, so the patch never fully seals your mouth, and it peels off in one movement. Even so, mouth tape is only for people who breathe easily through the nose; if your nose blocks during the night, take it off.
Will mouth tape irritate my skin?
Redness, irritation and allergic reactions are among the most common side effects [10]. Test the patch while you're awake, don't apply it over broken or irritated skin, and stop if you react. pretty sleepy. uses a gentle, latex-free adhesive with a cushioning gel layer, but no adhesive suits everyone.
Does it work?
Does mouth tape work?
It reliably keeps your lips closed; whether that improves health is unproven. A 2025 systematic review found only 10 studies with 213 patients in total: two showed improvements in sleep apnoea measures and the rest found no difference [1]. A separate 2025 scoping review described the research as "markedly heterogeneous" with "little consensus" [2].
Does mouth tape stop snoring?
The evidence is limited. Two small, uncontrolled studies of mouth-breathers with mild sleep apnoea reported lower snoring scores with mouth taping or porous oral patches [3][4], but the 2025 review judged the overall evidence weak [1]. Loud snoring can be a sign of sleep apnoea, so see a GP. pretty sleepy. is a cosmetic product and is not intended to reduce snoring.
Does mouth tape help sleep apnoea?
Not reliably. One study of 20 people with mild sleep apnoea [3] and one of 30 [4] found improvements, but reviewers warn of harm when people tape without assessment [1]. If you might have sleep apnoea, get assessed before trying any mouth tape.
What are the benefits of mouth taping?
The claimed benefits are nose breathing, less dry mouth, quieter sleep and fresher breath. The Sleep Foundation's review says most reported benefits remain anecdotal; the limited research support is for snoring and apnoea measures in people with mild sleep apnoea [9]. pretty sleepy.'s benefits are cosmetic: lips held closed overnight and softer, more hydrated-looking lips by morning.
Does mouth tape help your jawline?
No. There's no scientific evidence that mouth taping changes jawline shape, which depends on factors such as genetics and body fat [9].
Does mouth taping help dry mouth?
It hasn't been studied directly, and the Sleep Foundation lists dry mouth among the anecdotal claims [9]. One small lab study found that forced mouth breathing during sleep lowered the mouth's pH compared with nose breathing [5]. Dry mouth often has other causes, including medicines [12], so talk to your GP or dentist if it persists; pretty sleepy. is not a treatment for dry mouth.
Can mouth tape help with teeth grinding or TMJ?
There's no good evidence that it does. Grinding and jaw pain need a dentist's assessment.
Is nose breathing better than mouth breathing?
Your nose filters, warms and humidifies air before it reaches your lungs and your mouth doesn't, as Australian allergist Professor Connie Katelaris explained to the ABC [11]. That's the reasoning behind mouth taping. It doesn't follow that taping improves health, and anyone who can't breathe comfortably through the nose shouldn't tape.
Can you still snore with mouth tape on?
Yes. Snoring isn't only an open-mouth problem, and one study found some people kept breathing through the mouth around the tape ("mouth puffing") [10]. Loud or regular snoring is worth a GP visit.
Using mouth tape
How do you use mouth tape?
Check you can breathe easily through your nose and try the tape while awake first [9]. Apply it to clean, dry lips with your mouth gently closed, pressing from the centre outwards. In the morning, peel it off slowly from one corner. Skip it on any night your nose is blocked.
Should I try mouth tape during the day first?
Yes. Wearing it for a while when you're awake shows whether you can breathe comfortably through your nose and whether your skin tolerates the adhesive [9].
Can I wear lip balm under mouth tape?
Oils and balms stop adhesive sticking, so apply mouth tape to clean, dry skin. With pretty sleepy., the gel layer does the moisturising, so you don't need balm underneath.
Does mouth tape work with a beard or moustache?
It's harder, because adhesive sticks to skin, not hair, and removal can pull. Trim the hair just above the lip so the edges sit on skin, press firmly, and peel slowly. Very full moustaches may stop any mouth tape sticking well.
Does it hurt to take off?
It shouldn't. Peel slowly from one corner, keeping the patch low and close to the skin rather than pulling straight out. A little warm water on the edge helps if it's stubborn.
What if mouth tape comes off during the night?
It's common in the first few nights, usually because of skin oils, facial hair or moving your mouth in your sleep. Apply to clean, dry skin and hold the edges down for a few seconds.
Can I use normal tape (like Micropore) as mouth tape?
If you use tape, choose one made for skin: the Sleep Foundation suggests hypoallergenic, surgical or athletic tape and warns against masking tape and other non-body tapes [9]. One study used 3M silicone hypoallergenic tape [3]. Purpose-made strips add an easy-peel edge and often a vent.
Should mouth tape have a hole or vent?
Many people find a vent or slit less claustrophobic because the mouth isn't fully sealed. A vent doesn't make mouth tape suitable for a blocked nose, though. Every pretty sleepy. patch has a breathing vent in the centre.
Should I use mouth tape every night?
There are no guidelines on how often to use it [9]. Use it on nights your nose is clear, skip nights you're congested or unwell, and give your skin a break if it gets irritated.
Can I use mouth tape after lip filler?
Ask your injector first, and wait until any swelling or tenderness has settled before putting adhesive on your lips.

Lips
Does mouth tape dry out your lips?
Plain tape adds no moisture, and peeling adhesive off dry lips can leave them flaky. Lips lose water about three times faster than cheek skin [6], so they dry out easily overnight. A gel-lined collagen tape covers the lips with a hydrating layer instead of bare fabric.
Why are my lips dry in the morning?
Lip skin has a weaker barrier than the rest of the face: in a study of 303 women, water loss through the lips was almost three times that of the cheek and surface hydration about a third [6]. Sleeping with your mouth open and dry air add to it. If cracking or soreness persists, see a GP or dermatologist.
Does hyaluronic acid help dry lips?
Hyaluronic acid binds water. In a 60-day trial on the skin around the eyes, 0.1% hyaluronic acid creams improved hydration and elasticity compared with placebo [7]. It hasn't been studied on lips specifically, but it's common in lip care for the same reason.
How do I make lip lines look smoother?
Keep lips hydrated, wear sunscreen or SPF lip balm by day and avoid smoking: sun damage and tobacco smoke are the main causes of fine lines [14]. Overnight lip care such as a lip mask or collagen mouth tape keeps lips hydrated so lines look smoother. For deeper lines, a dermatologist can talk you through in-clinic options [14].
