Most of us have woken up with one at some point: a surprisingly deep line running across the cheek, a crease beside the eye or an imprint from the pillow that makes one side of the face look considerably more rumpled than the other.
Usually, it disappears somewhere between brushing your teeth and finishing breakfast. As skin becomes less elastic with age, however, those morning creases can take longer to settle, which raises an obvious question: if your face is pressed against a pillow for several hours every night, can your sleeping position eventually contribute to permanent wrinkles?
There is some science behind the idea of sleep wrinkles, although the answer is more nuanced than simply saying that side sleeping makes you age faster. Mechanical compression does distort the skin while we sleep, particularly when lying on the side or stomach, and repeated folding may contribute to certain lines over time. At the same time, sleep position is only one small part of facial ageing, alongside much more established influences such as UV exposure, genetics and the natural structural changes that occur in the skin as we get older.
So if you are a lifelong side sleeper, there is no need to start training yourself to lie rigidly on your back tonight. It is simply worth understanding what those morning lines are, why they become more noticeable with age and which habits are actually worth paying attention to.
About This Guide
This guide looks at what people commonly call pillow wrinkles or sleep lines, whether sleeping on your side or stomach can contribute to them, and what you can realistically do if they bother you.
It also separates some of the more exaggerated claims around sleep ageing from what we actually know. Your sleeping position may influence the way your face is compressed overnight, but it is not the sole reason wrinkles develop, and changing your pillowcase will not replace the basics of good skincare.
Who Is This Guide For?
You may find this particularly relevant if you regularly wake up with creases across the cheeks, around the eyes or along the lower face and have noticed that they no longer disappear as quickly as they once did.
It may also be useful if you are beginning to notice changes in skin elasticity, hydration or fine lines in your 30s, 40s and beyond and are wondering how much your everyday habits contribute.
Key Takeaways
Sleep lines are different from expression lines. They develop when the face is physically compressed or folded against a pillow rather than through repeated muscle movement such as smiling or frowning.
Side and stomach sleeping create more facial compression than sleeping on your back, and researchers have proposed that repeated mechanical stress may contribute to certain wrinkles over time. The evidence, however, is still relatively limited, and one study found no significant association between a person’s preferred sleeping side and the side showing more facial wrinkles.
More importantly, you should not sacrifice good-quality sleep simply to avoid a crease on your cheek. Poor sleep itself has been associated with poorer skin-barrier recovery and more visible signs of ageing, which makes a comfortable night’s sleep considerably more valuable than achieving the theoretically perfect sleeping position.

What Are Pillow Wrinkles?
Pillow wrinkles, more formally described as sleep lines or sleep wrinkles, are creases created when part of the face is compressed against a sleeping surface.
They do not necessarily follow the same pattern as the lines produced by facial expressions. A smile repeatedly folds the skin around the eyes and mouth in a particular direction; sleeping on your side can push, stretch and fold the cheek differently depending on your facial structure and the position of your head.
Researchers looking at the mechanics of sleep have described compression, tension and shear forces acting on the facial skin in side and stomach sleeping positions. These forces can produce quite dramatic temporary distortion while the face is against the pillow.
That does not mean every mark you see in the mirror after waking is becoming a permanent wrinkle. Temporary indentation is normal. The more interesting question is what happens after years of repeatedly folding the same areas of skin.
Why Do Sleep Lines Seem Worse as We Get Older?
One reason people suddenly become aware of pillow lines in their 30s or 40s is that the skin no longer behaves exactly as it did at 20.
As we age, structural changes occur throughout the skin. Collagen and elastin gradually change, skin becomes thinner and often drier, and the face also undergoes changes in volume and supporting tissues. These processes are part of normal intrinsic ageing and affect how readily the skin springs back after being folded or compressed.
A crease that disappeared quickly in younger skin may therefore remain visible for longer after waking. That does not necessarily mean the pillow created the entire line overnight; rather, mechanical folding may make an existing tendency more obvious.
This is also why dehydration can make fine lines look considerably more pronounced. Well-moisturised skin tends to look plumper and smoother on the surface, while dry or dehydrated skin can make every small crease more visible. Moisturiser can therefore improve the appearance of fine lines, even though it does not rebuild the deeper structures responsible for ageing.
Does Sleeping on Your Side Cause Wrinkles?
It can certainly create more compression of one side of the face.
When you sleep on your side, part of the cheek, eye area and lower face is pressed into the pillow for extended periods. Laboratory observations have demonstrated visible facial deformation in these positions, and a review published in the Aesthetic Surgery Journal proposed that repeated distortion may contribute to the development of sleep wrinkles.
But there is an important qualification here.
The scientific literature on sleep position and long-term facial ageing is relatively small. A 2013 study involving 100 women compared their preferred sleep side with the side of the face showing greater wrinkling or ptosis and found no significant relationship.
That means it is reasonable to say that side sleeping repeatedly compresses the skin and may contribute to certain lines, but it would be much too strong to say that sleeping on your side will inevitably give you wrinkles or make one side of your face sag.
What About Sleeping on Your Stomach?
Stomach sleeping generally places even more of the face in contact with the pillow, depending on how the head is positioned.
From a purely mechanical point of view, that creates plenty of opportunity for the forehead, cheeks and eye area to be pressed or folded. Earlier clinical observations of sleep lines also described patients who habitually slept prone with their faces pressed into pillows.
Again, though, this should be kept in perspective. Sleeping position is not remotely comparable with years of unprotected UV exposure when we talk about the major preventable contributors to visible skin ageing.
Is Sleeping on Your Back Better for Your Skin?
If preventing facial compression is your only consideration, yes. Sleeping on the back keeps most of the face away from the pillow, which is why dermatologists sometimes suggest it as a simple way to reduce repeated sleep creases for people who are comfortable in that position.
The phrase “if you are comfortable” matters.
There is little benefit in forcing yourself into a sleeping position that causes you to spend half the night awake. Sleep quality has its own relationship with skin health. A study comparing good and poor sleepers found that poorer sleep was associated with higher measures of intrinsic ageing and slower skin-barrier recovery. Another controlled study in Korean women found that restricting sleep to four hours a night reduced skin hydration and elasticity and worsened several skin measurements over the course of six nights.
If you sleep beautifully on your side and miserably on your back, getting enough good-quality sleep is likely to be the more sensible priority.
Will a Silk Pillowcase Prevent Wrinkles?
Silk pillowcases have become almost synonymous with anti-ageing sleep, but the marketing often gets ahead of the evidence.
A smooth fabric may create less friction against the skin than a rougher material and can certainly feel more comfortable, particularly for people whose skin is easily irritated. What has not been convincingly demonstrated is that an ordinary silk pillowcase will prevent facial ageing or permanently stop wrinkles from forming.
There have been small studies of specially designed pillows and even copper-containing pillowcases, but those findings cannot simply be transferred to every satin or silk pillowcase on the market.
If you enjoy sleeping on silk, there is nothing wrong with using it. Just think of it as a comfort choice that may reduce friction rather than an anti-ageing treatment in its own right.
Does Your Pillow Matter?
Potentially, although mostly because it influences how your face and neck are positioned.
A very firm pillow that pushes strongly into the face may create more obvious morning compression marks than one that allows your head to rest comfortably without pressing heavily against the cheek. There are also specially shaped pillows designed to reduce facial contact for side sleepers.
Some small studies have explored these designs, but the evidence is not strong enough to say that everyone needs an “anti-wrinkle pillow”.
Comfort, spinal support and good sleep should still come before beauty claims printed on the packaging.
Can Skincare Stop Pillow Wrinkles?
Skincare cannot stop the physical act of your cheek folding against a pillow, but keeping the skin well hydrated can make superficial lines look less obvious and support a healthier barrier.
A good evening routine does not need to be elaborate. Gentle cleansing, an appropriate moisturiser and any well-tolerated treatment products you already use consistently are generally more useful than buying something specifically marketed for “sleep wrinkles”.
During the day, sunscreen remains considerably more important for long-term wrinkle prevention than your pillowcase. UV radiation is one of the major modifiable contributors to premature skin ageing, which is why dermatologists consistently recommend daily broad-spectrum SPF 30 or higher.
If anti-ageing is the goal, that is where we would place the priority.
What Actually Matters Most for Preventing Premature Skin Ageing?
It is easy to become fixated on small habits once we start noticing fine lines. We begin analysing which side we sleep on, whether our pillow is too firm and whether our sheets contain the correct fibres, while overlooking the habits with much stronger evidence behind them.
Daily sun protection matters enormously. So does avoiding smoking, looking after a dry or compromised skin barrier, using appropriate skincare consistently and getting enough sleep.
Sleeping on your back may be an additional measure if it is comfortable for you, but it belongs much further down that list.
Can a Facial Get Rid of Pillow Wrinkles?
A facial cannot permanently remove a fixed wrinkle caused by structural changes in the skin, and it cannot stop your face from being compressed again the following night. What a good facial can do is improve hydration and surface smoothness, address dull or dehydrated skin and use massage and skincare to leave the complexion looking fresher and more rested.
Fine dehydration lines can appear softer when the skin is properly hydrated, which is quite different from claiming that a facial has rebuilt the skin or erased an established wrinkle.
Where BeKind Pro Fits In
At My Cozy Room, our BeKind Pro Anti-Aging Facial is designed for clients who are beginning to notice concerns such as dehydration, dullness, fine lines and reduced firmness and want a treatment that combines skincare with a deeply relaxing facial experience.
The 24-step, 120-minute treatment incorporates hydration-focused skincare alongside facial massage, our Royal Brass Comb ritual, Golden Contour Gua Sha, ultrasonic application and cooling steps. Rather than positioning it as something that can “reverse” sleep wrinkles, we see it as supportive care for skin that is becoming drier, less supple or more tired-looking with age.
The massage and gua sha elements can also make the face feel less tense and temporarily look fresher, while the hydrating stages help soften the appearance of fine dehydration lines.
For someone who regularly wakes with pillow creases that take longer to disappear than they once did, that may be a sign that it is worth paying more attention to overall hydration and skin resilience rather than blaming the pillow alone.
Frequently Asked Questions About Pillow Wrinkles
Are pillow wrinkles real?
Yes, in the sense that pressure from a pillow can visibly fold and distort the facial skin during sleep. Researchers have documented these mechanical forces and proposed that repeated compression may contribute to sleep lines over time. The amount that sleeping position contributes to permanent facial ageing, however, is less certain.
Are sleep wrinkles different from expression lines?
They can be. Expression lines develop along patterns created by repeated facial muscle movement, while sleep lines are associated with external compression and folding of the skin. Their direction and location can therefore look different.
Does sleeping on your side make one side of your face age faster?
Not necessarily. Although side sleeping creates more compression on the side touching the pillow, research has not consistently shown that a person’s preferred sleeping side corresponds with greater wrinkles or sagging on that side.
Is back sleeping best for preventing wrinkles?
Back sleeping removes much of the direct facial contact with the pillow and can therefore reduce overnight compression. If you find it comfortable, it is a reasonable option. There is no reason to sacrifice sleep quality simply to remain on your back, however.
Do silk pillowcases prevent wrinkles?
There is not strong evidence that a standard silk pillowcase prevents facial ageing. Its smoother surface may reduce friction and feel gentler against the skin, but it should not be regarded as a substitute for sunscreen, moisturising or other established anti-ageing habits.
Why do pillow marks take longer to disappear as I get older?
Ageing skin gradually becomes less elastic and often drier, so it may not rebound from temporary compression as quickly as younger skin. Existing fine lines can also make the morning crease look more obvious.
Can moisturiser help sleep lines?
Moisturiser can increase surface hydration and temporarily make fine lines appear softer or less noticeable. It does not permanently remove established wrinkles.
Can a facial prevent sleep wrinkles?
A facial cannot prevent your skin from being physically compressed while you sleep. What it can do is support hydration, comfort and the appearance of smoother, fresher skin, particularly when dehydration is making fine lines look more pronounced.
So, Should You Change the Way You Sleep?
If you already enjoy sleeping on your back, there is no harm in continuing. It reduces facial contact with the pillow and may help minimise the repeated folding that creates obvious sleep lines.
If you are a committed side sleeper, there is equally no need to panic.
The evidence does not support treating your sleeping position as one of the major causes of premature ageing, and maintaining good-quality sleep is important in its own right. A comfortable pillow, adequately hydrated skin and perhaps a smoother pillowcase can all make mornings a little kinder to the face, but they are supporting players rather than the foundation of an anti-ageing routine.
For long-term skin health, sunscreen, sensible skincare, adequate sleep and consistency still matter far more.
