Does face taping work?
Face tape holds skin flat while it is on and changes nothing once it comes off; lines return within hours. Mouth taping does not change adult facial bone, and it is dangerous if you have undiagnosed sleep apnea or cannot breathe freely through your nose. If you snore, wake gasping, or are sleepy in the day, get tested before you ever tape.

Do your facial analysis: Side profile analysis →Two different practices, often confused
Face taping means applying adhesive strips across the forehead, between the brows, or along the jaw and neck, usually overnight, to hold the skin flat and stop expression lines from folding. It is an old technique from film and theatre, where tape and thread lift the skin invisibly under a hairline for the length of a scene.
Mouth taping is unrelated in mechanism: a strip over the lips during sleep to force nasal breathing. It circulates in two versions, one framed around sleep quality, and one promising jaw definition and "facial gains" through nasal breathing and tongue posture. The two get discussed together, but they make different claims and carry very different risks.
What actually happens
Tape on the face works purely by holding position. While it is on, a fold is prevented from forming; when it comes off, the skin returns to where its underlying collagen and elastin hold it. Any smoothness in the morning is temporary, on the order of hours. There is no mechanism by which brief mechanical positioning rebuilds the dermal structure that determines where lines sit.
Mouth taping does not change bone. The jawline claims rest on the same assumption as mewing, that nasal breathing and tongue position remodel the adult face, and the same problem applies: the facial skeleton has finished growing, and no controlled study has measured a structural change. Nasal breathing during sleep has its own merits. A sharper jaw is not among the demonstrated ones.
The real risks
The serious one is mouth taping with undiagnosed obstructive sleep apnea. In apnea the airway collapses repeatedly during sleep, and the mouth is a fallback route for air. Taping it shut removes that route. Snoring, daytime sleepiness, waking gasping, or a partner noticing you stop breathing are all reasons to be tested before considering it, and if you have any of them, do not tape.
The same applies to anyone who cannot breathe comfortably through their nose: a deviated septum, chronic congestion, allergies, or a cold. Nausea and vomiting during sleep with a taped mouth is also a genuine hazard. Facial tape is milder but not free of cost, adhesive irritates skin, and repeated removal can damage a compromised barrier or pull at fragile skin around the eyes.
What is worth doing instead
If you mouth-breathe at night, treat that as a medical question rather than a cosmetic one. A doctor can check for nasal obstruction and screen for sleep apnea, and both have real treatments. Apnea in particular affects cardiovascular health, daytime function and mood, finding it is worth far more than any jawline outcome that prompted the search.
Tonight, do not tape your mouth if you snore, wake gasping, have daytime sleepiness, or a blocked nose; see a doctor about the airway instead, because apnea is a cardiovascular problem, not a cosmetic one. For lines, use sunscreen daily, a retinoid if tolerated, and sleep on your back if side-sleeping creases are the real issue. The side profile analysis measures your facial convexity and E-line from a photo, a better record than a before-and-after under tape. Adhesive irritation on the same spot nightly is a reason to stop.
FAQ
Common questions
Does mouth taping give you a jawline?+
There is no evidence that it does. The claim depends on nasal breathing and tongue posture remodeling adult facial bone, which has not been demonstrated. Any change people notice over the months they try it is more readily explained by body fat, age and photography.
Is mouth taping safe?+
Not for everyone, and the exceptions matter. If you have or might have sleep apnea, or you cannot breathe comfortably through your nose, taping removes your backup airway. Snoring, waking gasping, or daytime sleepiness are reasons to get tested first rather than to tape harder.
Does face tape get rid of wrinkles?+
Only while it is on, and for a short time afterward. It holds skin flat mechanically; it does not change the collagen and elastin that determine where lines form. Established lines return once the tape is removed.
Can face tape damage your skin?+
It can. Adhesive causes irritation and contact dermatitis in some people, and repeated pulling stresses the skin, particularly the thin skin around the eyes and any skin whose barrier is already compromised. Nightly use on the same area is the pattern most likely to cause problems.
