Smile lines get a bad rap.

One day you’re laughing in the mirror, and the next you’re wondering if your face aged overnight. Whether you’re 22 or 52, those creases can stir up panic.

But here’s the truth, deep smile lines are normal, common, and totally manageable. In this guide, we’ll break down what causes them, when to worry (or not), and what actually works to treat them, from at-home skincare to expert-backed procedures.

Deep smile lines are not a flaw. They’re part of how your face moves, expresses, and connects.

Clinically, we call them nasolabial folds, those creases that run from the sides of your nose down to the corners of your mouth. They deepen when you smile, laugh, or speak, which is why they’re sometimes affectionately (and sometimes not-so-affectionately) called smile lines.

But here’s where things get misunderstood. There are two kinds of smile lines:

• Dynamic lines, which only show up when you’re using your facial muscles, smiling, laughing, frowning, even chewing.
• Static lines, which are visible even when your face is at rest. These tend to develop over time as your skin loses collagen, or when volume shifts in the midface.

The truth is, you don’t have to be “old” to have them.

I’ve seen teens with smile lines and women in their 20s whisper, “I thought I was broken.” You’re not. What you’re seeing could be structure, early collagen loss, or just lighting.

Yes, lighting makes a huge difference. Overhead lighting (think: office fluorescents or Zoom calls) casts shadows that deepen those folds. Side lighting, or natural diffused light, tends to be much more forgiving.

Sometimes, the “wrinkle” you’re seeing is just a shadow caused by a dip in facial volume, not a line at all.

Here’s what I want you to remember: smile lines are normal. And in many cases, they’re a sign of a face that moves, laughs, and feels deeply.

We don’t erase that, we honor it, and if you choose, we enhance it in a way that keeps you recognizable in the mirror.

Let’s bust the biggest myth first: deep smile lines aren’t just about getting older.

Yes, time plays a role, but it’s only one piece of the puzzle. I’ve seen women in their 40s with smooth skin and 20-somethings worried about “premature aging.” But smile lines aren’t just about age, many other factors are at play.

As we get older, our skin naturally produces less collagen and elastin. These are the proteins that keep skin firm, springy, and resilient.

Without them, skin starts to thin and sag, and those creases that used to show up only when you smiled? They start sticking around even when you’re not.

Let’s talk about muscle memory.

Every time you smile, laugh, frown, or clench your jaw when you’re stressed, you’re creating little muscle contractions. Over time, those repeated movements etch into the skin. That’s how dynamic lines turn into static ones.

I love expressive faces. But if you’re someone who smiles big and often (and I hope you are), it’s normal for those folds to appear sooner.

This one is often overlooked but so important: what you’re seeing may not be a line, it might be a shadow.

When we lose volume in our midface (especially the apple of the cheek), the skin has less support. That hollowing causes light to fall differently, creating a deeper-looking fold. It’s not necessarily the skin folding, sometimes it’s the structure underneath changing.

If you’ve ever noticed your lines look deeper after a beach day or a night out with little water, it’s not your imagination. Dehydrated skin collapses more easily, making folds appear worse.

Sun damage doesn’t help either, UV rays break down collagen and elastin at a cellular level, speeding up everything we’re trying to slow down.

Some people are simply born with more prominent folds. If your cheekbones sit lower, or your midface is naturally flatter, you might notice smile lines earlier, even if your skin is plump and healthy.

This is about structure, not neglect.

Smoking is a big one. It reduces oxygen to the skin, impairs healing, and degrades collagen. But even high stress, lack of sleep, and poor nutrition can fast-track volume loss and skin aging.

You are your habits, and your skin will absolutely tell the story.

Here’s the question I hear all the time: “Why do my smile lines look so much deeper than my friend’s, and we’re the same age?”

The answer? It’s rarely just about age. In fact, most of what makes smile lines more or less noticeable has to do with structure, hydration, and perception, not how “old” your skin is.

Flatter cheekbones mean less midface support, making smile lines appear earlier, even with healthy skin. It’s not premature aging; it’s just how your face is built.

As we age, cheek fat pads subtly shift downward, reducing midface support and deepening smile lines. Midface filler helps restore balance, not add bulk, by softening the contrast between high and low points.

Dehydrated skin folds more easily, making smile lines appear deeper.

Once clients start using hydrating products like our Nourishing HA Peptide Serum, their lines often look softer, sometimes before any in-office treatment. Moisturized skin reflects light better, creating a visibly smoother look.

Social media skews reality, filters hide texture, movement, and smile lines. But everyone has them, even celebrities. The difference? Good lighting, subtle edits, and thoughtful aesthetic care that enhances, not erases, natural beauty.

Too often, I see amazing women in their 20s feel like they’ve “failed” at youth because of a few lines. That anxiety is real, but misplaced. Your face is doing what it’s meant to do. The goal isn’t erasure, it’s understanding, and making informed choices with clarity and support.

No, deep smile lines at a young age are not a red flag. They’re not a failure of skincare, a sign you’re “aging wrong,” or proof you’ve done something wrong.

In fact, for many people, especially those with expressive faces, they’re completely normal.

I’ve seen 14-year-olds with nasolabial folds. I’ve treated women in their twenties who’ve been hyper-focused on them since their teen years.

And I’ve personally reassured clients, “This is your face doing what it’s built to do.” Some of the most joyful, engaging people I know have had smile lines their entire lives.

Smile lines form where the face folds most often, and for people who smile easily, laugh freely, or have naturally animated expressions, those folds show up sooner.

Even toddlers have nasolabial folds if you look closely! What we consider “deep” is often just the way the muscles and fat pads beneath the skin are structured.

If you’ve ever looked in the mirror and panicked, “I’m only 22, how do I already have these?”, you’re not alone. And you’re not broken. You’re simply human.

That said, there are a few situations where smile lines might signal something more than just movement or structure:

• Sudden deepening over a short period of time could be a sign of rapid volume loss, often from extreme weight loss, dehydration, or hormonal shifts.
• Asymmetry, if one side looks dramatically deeper than the other, it could be tied to your sleep posture, side-sleeping habits, or even how you rest your hand on your face during the day.

In these cases, it’s worth a consult, not because you’re in danger, but because we can help you understand what’s really happening beneath the surface.

If you’re looking to soften, or even eliminate, the look of deep smile lines, the key isn’t just picking one magic product. It’s about stacking strategies that work together.

Some of the best results I’ve seen come not from aggressive intervention, but from intentional, layered care. Here’s what I recommend, and what to skip.

If your skin is dehydrated, smile lines will always look worse. Period.

• Drink more water. Yes, it sounds basic, but it matters. Internal hydration supports plumpness from within.
• Use humectants like hyaluronic acid. These ingredients pull moisture into the skin, giving it that glassy, bounce-back quality.
• Never skip SPF. Sun damage is the #1 collagen killer. UVA rays penetrate deep into your dermis, even through clouds and windows, and accelerate the structural changes that deepen folds.

Skincare won’t erase smile lines, but it will make your skin healthier, thicker, and more elastic, making those folds softer and less etched.

• Retinol or Retinoids: These vitamin A derivatives speed up cell turnover and thicken the dermis over time.
• Vitamin C + Peptides: These antioxidants help fight free radical damage and support new collagen formation.

My personal product recommendations from the Maria Kane line:

• Brightening CE Ferulic Serum: High-potency vitamin C with ferulic acid to brighten and defend.

• Triple Action Antioxidant Cream: Combats oxidative stress, hydrates deeply, and repairs the barrier.
  

• Overnight Youth Booster: Designed to work while you sleep, because that’s when your skin is in repair mode.
  

• Nourishing HA Peptide Serum: Hydration and firmness in one. Especially good for smile line areas that tend to collapse during the day.
  

Here’s where I’ll save you time and money:

• Drugstore wrinkle creams may smell nice and feel moisturizing, but most lack the ingredient concentration or delivery system to penetrate where changes happen.
• Spot-treating with Botox near the mouth is a common request, but it’s not always the right tool for this area. Botox relaxes muscles; smile lines usually need volume and lift, not paralysis.
• Too much filler directly in the fold can create that dreaded “chipmunk cheek” look. At The Skin Company, we believe in balance. The goal is harmony, not heaviness.

When done thoughtfully, professional treatments can significantly reduce deep smile lines without making you look frozen or puffy.

Midface Filler: Instead of dumping product into the line, we restore lost volume to the cheek area, which gently lifts and smooths the fold.

SkinVive: This revolutionary microdroplet HA injection improves skin quality. It works like hydration from the inside out, increasing glow and elasticity.

Microneedling (Collagen Induction Therapy): By creating controlled micro-injuries, your skin goes into healing mode and produces new collagen. It’s subtle but builds over time.

IPL (Intense Pulsed Light): This light-based treatment stimulates collagen while evening skin tone and texture. When used in a series, it gives skin a firmer, more youthful appearance.

Our Approach At The Skin Company:

We don’t chase fads or one-size-fits-all solutions. We combine high-level injectables, skin treatments, and skincare to give you long-lasting, natural results, without overfilling or overpromising.

We believe in subtle restoration, not transformation. Because when your skin is well-supported, the lines soften, but you still look like you.

Treating deep smile lines should never feel like guesswork or pressure. It starts with understanding what’s really happening beneath the surface.

Are your folds due to volume loss? Natural structure? Static wrinkles that have settled over time? We help you figure that out, with clarity, not sales scripts.

Our team builds gentle, layered treatment plans that might include SkinVive for hydration, IPL to stimulate collagen, and medical-grade skincare to support your results at home.

We don’t oversell. We don’t overfill. And we’ll never suggest a treatment you don’t truly need.
