Yes, you absolutely can use Botox for smile lines. It’s a fantastic way to soften those little creases that appear around your mouth when you smile or laugh. The goal isn’t to erase your expression but to relax the specific muscles causing the skin to fold, giving you a smoother, more refreshed look while keeping your smile as natural as ever.
How Botox Softens Smile Lines for a Natural Look

Smile lines, which we often call nasolabial folds, are a completely normal part of a life well-lived. Think of it like this: imagine folding a piece of paper repeatedly in the same spot. At first, it smooths out easily. But after thousands of folds, a permanent crease begins to set in. Our skin behaves in much the same way after years of smiling, laughing, and expressing ourselves.
It’s these repetitive muscle movements that create the lines running from the side of your nose down to the corners of your mouth. Knowing this helps us understand how we can treat them effectively.
Dynamic vs Static Lines
When we look at smile lines, we see two different types, and knowing which you have helps us choose the right approach.
- Dynamic Lines: These are the lines that show up only when you’re actively smiling or laughing. As soon as your face rests, they vanish.
- Static Lines: These are the lines that stick around, even when your face is completely still. They’ve formed over years from those repeated dynamic movements, combined with a natural loss of skin elasticity and collagen.
Botox is a superstar when it comes to treating dynamic lines. By relaxing the muscles that create the crease, it stops the lines from forming so deeply when you smile.
By gently interrupting the signals that tell certain facial muscles to contract, Botox allows the skin’s surface to smooth out. It’s not about freezing your smile, but simply softening its impact on your skin over time.
How Botox Is Different From Dermal Fillers
Many people think Botox "fills" wrinkles, but that’s actually the job of dermal fillers. Botox works on a totally different principle—it’s a neuromodulator.
Its purpose is to relax the small muscles around your mouth that pull the skin inward when you express yourself. With less muscle activity, the skin doesn't fold as intensely, which visibly softens those dynamic smile lines. As a bonus, this also helps prevent static lines from getting deeper over the years.
Here at Switch Dental in Lower Hutt, our dental professionals have an intimate knowledge of facial anatomy. This specialised expertise means we can place Botox with incredible precision, ensuring you get a subtle, natural-looking result that refreshes your whole appearance without ever compromising your beautiful smile.
Is Botox the Right Treatment for Your Smile Lines?
Figuring out the best way to treat your smile lines comes down to understanding what’s causing them in the first place. Is it the way your face moves when you laugh, or is it a line that’s there all the time? Answering that question is the key to deciding if Botox is the right fit for you.
Simply put, Botox for smile lines works wonders on dynamic lines. These are the creases that pop up when you express yourself—like when you smile or laugh—but mostly vanish when your face is relaxed. If your main concern is the lines that appear with movement, Botox can give you a fantastic, natural-looking result by gently relaxing the muscles that cause the skin to fold.
Who Is the Ideal Candidate for Botox?
The best candidates are usually people who want to soften those expression lines around their mouth. It’s a popular choice for anyone who’s started to notice their smile lines are becoming a bit more defined and wants to keep them from getting deeper. Think of it as a proactive step to prevent those temporary, dynamic creases from setting into permanent, static lines.
You’re likely a great candidate for smile line Botox if:
- Your lines are most noticeable when you’re actively smiling.
- You want to stop existing expression lines from etching deeper into the skin.
- You’re after a subtle refresh that looks natural, not a drastic change.
We’re also seeing a lot more younger people in New Zealand opting for preventative Botox. They might not have any real lines yet, but they use the treatment to stop them from forming in the first place. At Switch Dental, we follow the ethical guidelines set by the New Zealand Society of Cosmetic Medicine, which means we only offer cosmetic Botox to patients 18 years and older.
When Another Treatment Might Be Better
While Botox is a game-changer for dynamic lines, it can’t do everything. If your smile lines are quite deep and stick around even when your face is completely still, we’d call those static lines. For these, a different approach often yields much better results.
Botox works by relaxing muscles; it doesn't add volume. For deep-set static lines, which are caused by a loss of collagen and facial volume over time, dermal fillers are usually the more effective choice.
Here’s a helpful way to think about it: Botox is like an iron, smoothing out a temporary crease in a shirt caused by folding (muscle movement). Dermal fillers, on the other hand, are like spackle, filling in a crack that’s already formed in the wall (volume loss). In many cases, the ultimate solution is actually a combination of both, giving a truly comprehensive and natural-looking result.
This is exactly why a proper, one-on-one consultation is so critical. Here at our Lower Hutt clinic, we guide, we don’t lecture. We’ll have a good look at your unique facial structure and have a chat about what you’d like to achieve. From there, we’ll give you our honest, professional advice so you can make an informed choice. Sometimes, that means recommending another of our cosmetic services, like our Botox for jaw clenching, which can also help create a softer overall facial appearance.
Your Botox Appointment Journey at Switch Dental

We get it—walking into a clinic for a cosmetic treatment can feel a bit intimidating, especially if it’s your first time. That’s why we’ve made our Botox appointments at our Lower Hutt practice genuinely welcoming and straightforward. Our whole approach is about listening to you and making sure you feel informed and in control, never rushed.
Everything starts with a relaxed, friendly chat. You’ll sit down with one of our highly skilled dental professionals who will take the time to really understand what you’re hoping to achieve. This is your time to ask anything and everything about using Botox for your smile lines. We'll talk through your goals to make sure the final result is exactly the natural, subtle look you have in mind.
Mapping and Preparation
Once we’re on the same page, we get down to the technical side of things. Your clinician will ask you to smile, laugh, and make a few other faces. It might feel a little silly, but it’s a crucial step that allows us to see precisely how your facial muscles move.
This mapping is where our expertise in facial anatomy comes into play. By seeing exactly which muscles create your smile lines, we can choose the perfect spots to treat—softening the lines without ever freezing your natural expression.
With the plan set, we’ll gently clean the area around your mouth and nose. Then, we apply a strong topical numbing cream to make sure you’re comfortable. It takes a few minutes to work its magic, but it makes the actual treatment a breeze.
The Quick and Gentle Treatment
Now for the treatment itself, which is over before you know it. Using an incredibly fine, hair-like needle, your clinician will make a few small, precise injections into the mapped-out muscles. Honestly, the whole injection part usually takes just a couple of minutes.
Most people tell us it feels like a tiny, quick pinch—if they feel anything at all. Between our gentle touch and the numbing cream, the experience is surprisingly comfortable.
The best part? The entire appointment, from our initial chat to the finished treatment, is usually done in under 30 minutes. It’s so quick you can easily pop in on your lunch break. We’ll walk you through every single step, so you can leave our clinic feeling confident and excited.

What to Expect After Your Botox Treatment

Knowing what happens after your appointment is just as important as the treatment itself. One of the first things I tell my patients is that Botox doesn't work instantly. The process is gradual, which is actually a good thing—it means your results will look refreshed and completely natural, not like you've had "work done."
You can expect to see the first hints of change within about 3 to 5 days. This is when you might notice a subtle softening of the lines around your mouth as the product starts to relax those specific muscles. It’s the first sign that the magic is beginning.
The Full Result and Longevity
Your final, beautifully smooth result will settle in at around the two-week mark. By this point, the muscles responsible for those deeper smile lines will be fully relaxed. Your skin will look noticeably smoother when you laugh and express yourself, but you'll still look like you.
Think of it like this: your results don't just appear overnight. It's a gradual reveal, ensuring the final look is refreshed and subtle, never frozen.
So, how long will it last? Most people find their newly softened smile lines stick around for about 3 to 4 months. This can change a little depending on things like your metabolism and how strong your facial muscles are. As the effects slowly fade, you'll see your original muscle movement and lines gradually return, which is simply your cue to book in for your next appointment. For a deeper dive, check out our guide on how long you can expect Botox results to last.
Maintaining Your Results and Planning Ahead
To keep that smooth, refreshed appearance long-term, consistency is your best friend. The good news is that the results are incredibly reliable. Clinical data from New Zealand shows a 95% treatment responder rate just one week after treatment. Better yet, 82% of patients were still responding well at 16 weeks post-treatment.
For most of my patients, this means scheduling follow-up sessions about three times a year to maintain their results seamlessly. In New Zealand, you can typically expect the annual cost for treating areas like smile lines and the forehead to be between $1,500 and $2,000, which covers these regular maintenance appointments.
Botox Compared to Dermal Fillers for Smile Lines

One of the most common questions we get is, "Should I get Botox or fillers for my smile lines?" It's a great question, and the answer isn't always straightforward. While both treatments are fantastic for refreshing your appearance, they work in completely different ways, and the right choice really depends on the kind of lines you have.
Here’s a simple analogy I like to use with my clients. Think of Botox for smile lines like an iron smoothing a creased shirt. It's designed to work on dynamic lines – the ones that form when your facial muscles contract, just like a shirt creases when it's folded. Botox gently relaxes those tiny muscles, preventing the skin from bunching up and forming lines when you smile or laugh.
Dermal fillers, on the other hand, are more like using spackle to fix a crack in the wall. They’re built for static lines and volume loss. These are the deeper folds that are visible even when your face is completely at rest. Fillers, usually made from a substance called hyaluronic acid, literally "fill in" those areas, restoring lost volume from underneath to plump the skin and smooth everything out.
Botox vs Dermal Fillers for Treating Smile Lines
To help you get a clearer picture, this table breaks down the key differences between these two popular cosmetic treatments for smile lines.
| Feature | Botox | Dermal Fillers |
|---|---|---|
| Primary Use | Treats dynamic lines caused by muscle movement. | Fills in static lines caused by volume loss. |
| How It Works | Temporarily relaxes muscles to stop creasing. | Adds volume to plump and lift the skin. |
| Best For | Softening expression lines that appear with smiles. | Correcting deep folds that are always present. |
| Results Timeline | Appears over 3-14 days. | Visible immediately. |
| How Long It Lasts | Typically 3 to 4 months. | Can last 6 to 18 months. |
Ultimately, choosing between Botox and fillers isn't always an either-or situation.
For many people, the best and most natural-looking outcome comes from a combination of both treatments. Using Botox to relax the muscle and a filler to restore volume can create a beautifully seamless result.
This is why a proper consultation is so important. When you come into Switch Dental, we don’t just look at the lines themselves; we assess your unique facial structure and talk about what you’re hoping to achieve. This personalised strategy ensures you get a fantastic, natural-looking result that makes you feel amazing.
Your Aftercare Plan and Potential Side Effects
Once your treatment is finished, the next 24 to 48 hours are all about letting the Botox for smile lines settle in and get to work. Think of it as a quiet period to ensure the product stays exactly where we so carefully placed it.
The main goal is to prevent the Botox from moving, or "migrating," to nearby muscles. A little bit of mindfulness right after your appointment helps guarantee the precise, natural-looking results we’re aiming for.
Post-Treatment Dos and Don’ts
We’ll walk you through everything in person, but here are the most important guidelines to follow after you leave our clinic:
- Do try to stay upright for the first 4-6 hours. This just means no napping or lying down flat straight away.
- Don’t hit the gym or do any strenuous exercise for at least 24 hours. A gentle walk is perfectly fine, but anything that gets you hot and sweaty should wait a day.
- Don’t rub, massage, or apply any firm pressure to the treated areas. When you wash your face, be extra gentle.
- Do skip the sauna, spa pool, or sunbathing for the first 48 hours, as high heat can interfere with the results.
Following these simple tips is the best way to protect your investment and let the treatment work beautifully.
A Transparent Look at Side Effects
Your safety and comfort are our top priorities, and that includes being completely open about any potential side effects. Thankfully, for the vast majority of our patients, any side effects from Botox are very minor and don't last long. It’s fairly common to see a little bit of redness, slight swelling, or even a small bruise at the injection sites, but this typically disappears within a day or two.
While serious complications are extremely rare, we make sure you're fully informed about every possibility. Our highly trained dental professionals take every precaution, from meticulous injection techniques to using only premium, approved products, to minimise all risks.
In very uncommon situations where the product might migrate, it could cause a slightly uneven smile or affect certain expressions. This is precisely why choosing an injector with an expert understanding of facial anatomy is non-negotiable. You can rest easy knowing our team has the experience and skill to deliver safe, predictable outcomes, and we're always here to answer your questions before and after your treatment.
Of course, it’s only natural to have a few questions before trying a new cosmetic treatment. To help put your mind at ease, we’ve answered some of the questions we hear most often about using Botox for smile lines.
How Many Units of Botox Will I Need for Smile Lines?
This is a classic "how long is a piece of string" question, as the answer is completely unique to you. The exact amount we use really depends on things like how strong your facial muscles are and the depth of your lines when you smile.
As a general guide, we're often looking at a very small, precise dose—typically between 2 to 5 units on each side. We always start with a "less is more" philosophy, especially around the mouth. Over-treating this area can interfere with your natural expression, so a skilled practitioner will always begin with the lowest effective dose to give you a soft, refreshed result.
Is the Treatment Painful?
Most of our clients say it feels like a tiny, quick pinch—a bit like a mosquito bite that’s over in a second. We use incredibly fine needles for this, and to make sure you’re comfortable, we apply a strong topical numbing cream before we begin.
The actual injection part of the appointment is very fast, usually taking just a few minutes. Any mild discomfort you might feel is gone almost instantly.
We prioritise your comfort at every step. Our gentle technique and the use of numbing cream ensure that the experience is far more comfortable than most people anticipate.
How Popular Is Botox in New Zealand?
Aesthetic treatments have become incredibly mainstream here in Aotearoa. The market for aesthetic injectables in New Zealand, which includes popular treatments like Botox for smile lines, was valued at an impressive $15.8 million in 2023. It’s clear that Kiwis are more open to and interested in these procedures than ever before.
Looking at the numbers from large clinic networks, almost 40% of their clients are regulars for anti-wrinkle injections. In dedicated cosmetic practices, women make up about 95% of the clientele, and the most common age for starting treatment is between 50 and 54. You can read more about these New Zealand trends over at Medical Device Network.
Will I Still Be Able to Smile Naturally?
Absolutely. This is our number one priority and a question we get all the time. The goal is never to "freeze" your smile, but simply to soften the way the skin creases when you do.
A carefully trained injector targets only the tiny, specific muscles that pull the corners of your mouth down. By relaxing them just the right amount, your smile stays beautifully full and expressive, but the skin doesn't fold quite as deeply. The result is a smoother, more rested look, without ever taking away your ability to show happiness and warmth.
