These 5 Wrinkles Get Deeper Every Night. Most Women Don't Know Why. A dermatologist explains what's really deepening your expression lines — and the ~$30 overnight fix that's going viral.
Here's what most women don't realize: your wrinkles aren't just forming during the day. They're getting reinforced — and deepened — while you sleep.
Not from your pillow. Not from your sleeping position. From your own muscles.
Your facial muscles contract thousands of times a day. Every frown, every squint at your phone, every raised eyebrow on a Zoom call, every laugh. That's how expression lines form — and that part, most women understand.
But here's what they don't: those same muscles don't fully relax when you fall asleep. They stay partially contracted, holding your skin in the same folds and creases for six to eight hours straight. Every single night.
This is why expression lines keep getting deeper even when your skincare routine is dialed in. Retinol resurfaces the top layer of skin. Hyaluronic acid plumps it temporarily. But neither one stops the muscle underneath from folding your skin back into the same groove for eight hours every night.
Here are the five wrinkles where this matters most — and what dermatologists are now recommending women do about it before reaching for Botox.

What causes them: Every time you raise your eyebrows — in surprise, emphasis, or just looking up — the frontalis muscle across your forehead contracts and folds the skin horizontally. Decades of this create the lines you see.
Why they get deeper at night: The frontalis is one of the most tension-prone muscles on the face. Even during sleep, it holds residual contraction — especially if you carry stress in your forehead (most women do without realizing it). That means six to eight hours of your skin sitting in the same horizontal folds, every single night, with nothing stopping it.
Why retinol alone can't fix it: Retinol accelerates cell turnover on the surface. But the crease isn't a surface problem — it's a fold being reinforced by a muscle underneath. You're resurfacing the top of the paper while the fold stays pressed in from below.
What works overnight
Medical-grade face tape placed across the forehead holds the frontalis muscle flat while you sleep. The skin can't fold into the crease because the muscle can't contract into it. Over weeks, the crease softens because it's no longer being reinforced eight hours a night.
97% of women using NapBae's Beauty Sleep Face Tape reported smoother foreheads with fewer visible fine lines.
2. The 11 Lines (Frown Lines Between Your Brows)
What causes them: The corrugator muscles — two small muscles between your eyebrows — pull your brows together every time you concentrate, squint at a screen, or feel frustrated. They're the most overworked muscles on your face, and they produce those two vertical lines that make you look angry or tired even when you're neither.
Why they get deeper at night: Here's the cruel part. The corrugators are especially active during sleep. Studies on facial muscle tension during REM sleep show these muscles fire during dreaming and emotional processing. You're literally frowning in your sleep. Every night. For hours.
And because the 11 lines are pressed into a very narrow groove between the brows, the crease deepens faster than wider expression lines. It's concentrated, repeated folding in the same tiny spot.
Why Botox works here — but isn't the only option: Botox paralyzes these muscles so they can't contract. That's effective, but it costs $300-$600 per session, lasts 3-4 months, and some women don't want to lose the ability to express that area of their face entirely. Face tape offers the same principle — holding the muscle flat — without the injection, the cost, or the frozen look.
3. Crow's Feet
What causes them: Every smile and every squint activates the orbicularis oculi — the ring muscle around your eye. Over years, the repeated contraction fans out fine lines from the outer corners. They're called crow's feet because the pattern radiates outward like a bird's footprint.
Why they deepen faster than other wrinkles: The skin around your eyes is the thinnest on your entire face — up to ten times thinner than the skin on your cheeks. That means less collagen, less elastin, and less structural support to bounce back from repeated folding. The same crease that takes twenty years to set on your forehead can set in half that time beside your eyes.
And at night, your eyes don't fully relax either. During REM sleep, rapid eye movement activates the surrounding muscles. The skin around your eyes is being pulled, folded, and creased for hours — on the thinnest, most vulnerable skin on your face.
4. Smile Lines (Nasolabial Folds)
What causes them: The lines running from the sides of your nose to the corners of your mouth are created by the zygomaticus and levator muscles — the muscles responsible for smiling, laughing, and talking. They're some of the most-used muscles on your face, which is why nasolabial folds are often the first deep lines women notice.
The cruel irony: The more you smile, the deeper they get. And unlike forehead lines or 11 lines, smile lines have gravity working against them too. As collagen production slows after your late thirties, the cheek tissue above the fold loses volume and sags slightly, making the crease look deeper than the muscle alone would create.
Why they keep deepening at night: Even in sleep, the muscles around your mouth hold residual tension — especially if you clench your jaw or grind your teeth (which roughly 30% of adults do). The fold stays pressed in all night. And because gravity pulls the cheek tissue down while you lie on your side, the crease gets reinforced from both directions: muscle from below and weight from above.
Face tape placed along the nasolabial fold holds the skin smooth and the muscle relaxed overnight. Women who use it consistently report that their smile lines look noticeably softer within the first few weeks — not because the muscle is paralyzed, but because it's finally getting a break.
5. The Fine Lines You're Just Starting to Notice
This is the window most women miss.
There's a stage between "I think I see something" and "that's definitely a wrinkle." It usually happens in your late thirties to mid forties. A faint line on your forehead that wasn't there last year. A slight crease beside your mouth that only shows in certain light. The beginning of the 11s when you furrow your brows.
At this stage, the lines are still reversible. The crease hasn't fully set into the skin yet. The collagen structure can still bounce back. But every night those muscles contract into the same position, the crease gets a little more defined. A little more permanent.
This is exactly where face tape makes the biggest difference. Not after the line has been carved in for a decade. Not as a last resort before Botox. Right now, while the crease is still shallow enough that giving the muscle a nightly rest can genuinely prevent it from deepening.
So what is face tape, exactly?
Medical-grade, hypoallergenic strips that you apply to targeted areas of your face before bed. They gently hold overactive facial muscles in a relaxed, flat position while you sleep. The skin can't fold into the crease, the muscle gets a full night of rest, and over time the lines soften because they're no longer being reinforced for eight hours every night.
It's the same mechanical principle behind Botox — stop the muscle from contracting into the crease — without the needle, the cost, or the frozen look. Dermatologists have been recommending it as a first step before injectables, and in the last year it's gone viral as women realize their nighttime skincare routine has a gap that no serum can fill.
The problem is that most face tapes on the market have frustrating tradeoffs. Some use stiff, paper-based patches that harden on your face and require water to activate. Others make you skip your retinol and serums on nights you tape because their adhesive can't handle oil-based products. A few have barely any reviews.
After testing the most popular options, one stood out.
NapBae's Beauty Sleep Face Tape solved every issue the others had:
- Works over your entire skincare routine — retinol, serums, facial oils, all of it. No skipped nights.
- 110 pre-cut strips in two sizes — no scissors, no measuring. Apply to forehead, 11 lines, crow's feet, or smile lines in under a minute.
- Medical-grade, latex-free, hypoallergenic adhesive — firm enough to hold all night, peels off clean in the morning. No oil needed for removal.
- Flexible, breathable material — not stiff paper patches that harden. Comfortable enough to wear every night.
- $29.95 — less than a single unit of Botox. Less than one facial. A month's supply for the price of a nice lunch.
Based on customer-reported survey results.
Your retinol is doing its job. Your sunscreen is doing its job. But for eight hours every night, your muscles are undoing their work — folding your skin into the same creases, over and over, with nothing to stop them.
This is the step that fills the gap.
