You catch it in the mirror while brushing your teeth. The lines from the sides of your nose toward the corners of your mouth look deeper than they did last year. Maybe makeup settles there now. Maybe your face looks a little tired even when you feel fine. That moment sends many people searching for laugh lines treatment, but the answer usually isn't as simple as “fill the crease.”
Some laugh lines are mostly about volume loss in the cheeks. Others are driven by skin laxity, thinner skin, or the way the midface has shifted downward over time. In some people, the fold is part anatomy, part expression, and part skin quality. Two patients can point to the same line and need very different plans.
That's where people often get confused. A syringe can help, but not every fold should be treated the same way, and not every patient needs more volume placed directly into the line. Sometimes the better correction comes from lifting support above the fold. Sometimes it comes from improving the skin so the fold doesn't cast as much of a shadow. Often, the most natural result comes from combining approaches rather than asking one treatment to do everything.
A physician-led approach looks at the fold in context. How much cheek support have you lost? Is the lower face beginning to sag? Is the skin etched, crepey, or dehydrated? Do you want something reversible, something longer lasting, or something regenerative that builds gradually? Those questions matter more than the name of any single product.

Introduction to Laugh Lines and Why Treatment Choice Matters
A common scenario goes like this. A patient comes in asking for filler in the “smile lines,” but when they sit upright and smile, the deeper issue is easy to see. The cheek has flattened, the tissue has drifted lower, and the fold is only the visible endpoint of a broader structural change.
That distinction matters because laugh lines aren't just lines. They're often folds created by shadow, support loss, and skin aging together. If you only treat the crease, you can soften it, but you may not address what's making it deepen in the first place.
What most people notice first
For many adults, nasolabial folds start as lines that show mainly with expression. Later, they remain visible at rest. That shift is what usually changes the question from “Is this normal?” to “What can I do about it?”
Three treatment goals tend to come up:
- Soften the fold directly: Useful when the crease itself needs support.
- Lift the tissue above it: Helpful when descent in the midface or lower face is pushing more weight into the fold.
- Improve the skin around it: Important when etched texture and thinning skin make the area look older even after structure is corrected.
Practical rule: The deeper the fold looks at rest, the less useful it is to think of it as “just a wrinkle.”
Why one-size-fits-all treatment often disappoints
A natural result usually comes from matching the treatment to the cause. If the main issue is lost volume, filler may help most. If the tissue is sagging, a lifting treatment such as threads may reduce how much direct filling is needed. If the skin is dull, creased, or less elastic, regenerative and resurfacing treatments can improve the overall finish.
That cause-based approach also helps avoid overfilling. Laugh lines are part of normal facial anatomy. The goal usually isn't to erase them completely. It's to make them less dominant, so your face still looks like you.
What Causes Nasolabial Folds and How Treatments Target Them
Nasolabial folds form where the cheek meets the upper lip. Everyone has that boundary. What changes with age is how much it casts a shadow, how much the surrounding tissue descends, and how well the skin can rebound.
A simple way to picture it is a hammock tied between support posts. If the posts weaken and the fabric stretches, the middle sags. Your midface works in a similar way. Bone support changes, fat pads shift, collagen declines, and repeated facial movement keeps folding the same zone.
The four big contributors
Midface volume loss
When the upper cheek loses support, more weight settles toward the fold. That can make the line look heavier even if the fold itself hasn't changed much.Skin laxity and collagen loss
The skin becomes thinner and less springy. Instead of snapping back, it creases more easily and holds the fold longer.Underlying structural change
The face doesn't age only in the skin. Support below the skin changes too, which can make the fold look more fixed.Repeated expression
Smiling, talking, and facial movement don't “cause” all laugh lines, but they do repeatedly bend the same area.
Dynamic lines versus static folds
Many treatment conversations go off track. Dynamic lines are caused mainly by muscle movement. Static folds remain visible even at rest because structure and skin support have changed.
Botulinum toxin became part of cosmetic medicine on April 12, 2002, when the FDA approved botulinum toxin type A for temporary improvement of moderate to severe glabellar lines in adults under 65, following randomized placebo-controlled trials involving 405 patients and building on the earlier 1989 medical approval for blepharospasm and strabismus, as documented in the FDA approval letter for Botox. That history matters because it established the modern pathway for injectable wrinkle treatment, but it also helps explain why toxin alone usually isn't the main answer for nasolabial folds. These folds are usually more about support and volume than muscle pull alone.
A line that appears when you smile may respond to wrinkle-softening approaches. A fold that stays when your face is relaxed usually needs structural thinking.
Matching cause to treatment category
A practical map looks like this:
- Volume loss: often points toward filler
- Tissue descent: often points toward lift, including PDO threads
- Skin thinning or etched texture: often points toward regenerative or surface treatments
- Mixed causes: often benefit from combining more than one method
That's why a good laugh lines treatment plan starts with anatomy, not just product choice.
Dermal Fillers for Laugh Lines and How Formulation Affects Results
Dermal fillers are often the first treatment people consider for laugh lines because they can provide visible softening relatively quickly. But “filler” is a category, not a single thing. Product type, formulation, and placement all affect how the fold responds.
For a broad overview of filler types and treatment basics, this guide on dermal fillers and how they work is a useful starting point.
What hyaluronic acid fillers do well
Hyaluronic acid, or HA, fillers are commonly used when the goal is direct correction and reversibility. They add support where the fold dips and can also be used strategically in the midface when cheek support is part of the problem.
Clinical evidence for nasolabial folds is strong. In a prospective multicenter trial, success rates were 98.4% immediately after injection and 91% at 18 months, with mean nasolabial fold scores improving from 4.9 ± 0.4 at baseline to 2.2 ± 1.0 at 3 weeks and remaining improved at 2.9 ± 0.9 at 18 months, according to the clinical review of filler treatment for nasolabial folds.
That said, product selection isn't interchangeable. A 2024 systematic review and meta-analysis of 14 randomized clinical trials involving 1,190 patients found that monophasic HA outperformed biphasic HA for wrinkle improvement in nasolabial folds, with the biphasic group showing a smaller WSRS improvement of 0.18 with a 95% confidence interval of 0.16 to 0.20 and p < 0.00001, while adverse-event rates were similar, as reported in the 2024 HA filler formulation meta-analysis.
When collagen-stimulating fillers fit better
Some patients want more than immediate softening. They want a product that supports longer-term structural improvement. In that setting, collagen-stimulating fillers may be part of the discussion.
A 2024 systematic review and meta-analysis found that polycaprolactone, or PCL, showed greater 12-month GAIS improvement than HA, with RR 3.14, 95% CI 2.29 to 4.30, and p < 0.001, along with better WSRS improvement of 0.71, 95% CI 0.36 to 1.06, p < 0.001, according to the meta-analysis comparing PCL and HA in nasolabial folds.
That doesn't make one category universally “better.” It means the choice depends on whether you prioritize reversibility, speed, or durability.
Filler Options for Nasolabial Folds at a Glance
| Filler Type | How It Works | Durability Signal | Best When |
|---|---|---|---|
| Hyaluronic acid | Adds immediate support and volume | Durable correction shown through long follow-up in clinical study | You want direct softening and a reversible option |
| Monophasic HA | HA formulation associated with stronger wrinkle-severity improvement | Outperformed biphasic HA on wrinkle improvement in meta-analysis | Fold correction is the main goal |
| Biphasic HA | HA formulation with different gel structure | Improved folds, but less WSRS improvement than monophasic HA in meta-analysis | Selected when tissue behavior and injector preference fit |
| PCL | Supports collagen stimulation over time | Stronger 12-month improvement signal than HA in meta-analysis | You want longer-acting structural support |
Clinical takeaway: If two fillers are both “for smile lines,” that doesn't mean they'll behave the same in the tissue.
A separate 20-RCT network meta-analysis found that CaHA, PDLLA, and HA outperformed collagen at 6 to 9 months, and a 2026 equivalency trial reported that a new HA filler matched Juvéderm Ultra 4 for moderate to severe folds, as summarized in the network meta-analysis of injectable classes for nasolabial folds. For patients, that supports a practical point. The question usually isn't just what fills the line. It's what kind of correction you want over time.
PDO Thread Lifts for Lower Face Laxity That Deepens Laugh Lines
Some laugh lines deepen because the lower face and midface have started to descend. In that setting, adding volume into the fold alone can miss the main mechanical issue. PDO thread lifts approach the problem from another angle by helping reposition tissue and supporting collagen formation.
If you want a focused explanation of technique and candidacy, this overview of the PDO thread lift procedure explains the basics.
How threads help when the fold is being pushed from above
Threads don't “fill” a laugh line the way a gel filler does. They work more like internal support sutures. Depending on the thread design and placement, they can provide a lifting effect, improve contour, and stimulate collagen as the material gradually dissolves.
That difference matters. A patient with early jowling, cheek descent, or lower-face laxity may get a more balanced result when support is restored above the fold instead of repeatedly placing more volume directly into the crease.
The basic thread types in plain language
Different thread designs do different jobs:
- Smooth threads add subtle support and collagen stimulation.
- Twist threads provide a bit more structure in small areas that need localized reinforcement.
- Barbed threads grip tissue and are often used when lift is the priority.
- Molded threads can be selected when stronger structural engagement is needed.
At Medical Aesthetics and Lasers, thread choice can include smooth, twist, barbed, and molded options depending on anatomy and treatment goals. That matters because a patient with mild fold deepening and thin skin may need a different thread plan than someone with lower-face heaviness and early jowl formation.
When threads make sense
Threads may fit best when you notice signs like these:
- The cheeks look lower: The fold seems tied to heaviness above it.
- The jawline is less defined: Lower-face laxity is part of the picture.
- You want lift without surgery: You're looking for an office-based option with short downtime.
- You want to reduce filler demand: A lifting plan may decrease how much product needs to go into the fold itself.
Threads and fillers often complement each other. Lift can reduce the burden on the fold. Filler can refine what lift alone won't fully smooth.
What threads don't do
Threads can improve support and contour, but they don't replace surgery for advanced laxity, and they don't directly treat surface texture the way regenerative or resurfacing procedures can. They work best when used for the right problem. In laugh lines treatment, that problem is often descent, not just a crease.
Regenerative and Surface Treatments That Improve Skin Quality Around Folds
A fold can be structurally improved and still look older than it should if the skin around it is thin, etched, rough, or dull. That's why good laugh lines treatment often includes skin-quality work, not just volume or lift.
PRP and PRF for regenerative support
PRP and PRF aim to improve the tissue environment rather than occupy space. In facial rejuvenation, they're often used to support texture, tone, and overall skin quality.
For PRP, one clinical trial reported that 14 of 17 patients with nasolabial folds achieved more than 25% improvement in appearance, and the review noted no documented severe adverse events, according to the review of PRP in facial rejuvenation. A randomized clinical trial of PRP for photoaged facial skin also found it effective for facial rejuvenation, especially textural improvement, and reported no adverse events at 12 months in the JAMA Dermatology PRP trial.
PRF has a similar regenerative role. Injectable PRF significantly improved multiple FACE-Q outcomes, including satisfaction with skin, facial appearance, cheeks, lower face and jawline, and lips, with no major adverse effects reported, as shown in the injectable PRF facial rejuvenation study.
Surface treatments that improve the canvas
When folds look worse because of texture and laxity, surface treatments can help the area reflect light more smoothly.
A few examples include:
- Microneedling and RF microneedling: Useful when crepey texture, acne scarring, or reduced firmness are making folds stand out more. This overview of microneedling for loose skin explains where it fits.
- Chemical peels: Can improve tone and superficial texture around the lower face.
- Glass Skin Rejuvenation and Hydrafacial: These don't lift tissue, but they can improve brightness, hydration, and surface smoothness.
- Plasma Pen treatments: May help selected areas where targeted tightening is appropriate.
How to think about regenerative care
Regenerative and surface treatments usually work best as quality boosters. They don't replace volume when support is missing, and they don't replace lift when tissue descent is the issue.
Better skin quality doesn't erase a fold, but it can make every structural treatment look more natural.
Candidacy Downtime Safety and What to Expect From Consultation
Most patients don't need a long checklist. They need a clear way to sort which category fits their face and what trade-offs come with it.
A practical consultation focuses on what you see in the mirror, what's causing it, and how much downtime and reversibility matter to you.
A simple candidacy checklist
You may lean toward filler if the fold is the main issue, volume loss is noticeable, and you want a treatment that can be adjusted or reversed.
You may lean toward threads if the fold seems tied to sagging cheeks, lower-face heaviness, or a softer jawline.
You may lean toward regenerative or surface treatments if the area looks etched, thin, or rough, even when the fold itself isn't extremely deep.
Some people should pause and seek individualized guidance first. That includes patients with active skin infection in the area, uncontrolled inflammation, or medical issues that may affect healing. A consultation can also determine whether your goals are realistic for a nonsurgical approach.
Downtime tends to be manageable, but not identical
Most injectable and thread-based treatments involve some degree of swelling, tenderness, or bruising. The exact pattern depends on the treatment type, the product used, the area treated, and individual healing tendencies.
A few practical preparation points help:
- Arrive with clean skin: It makes treatment planning and skin assessment easier.
- Review medications and supplements: Your injector needs a full safety picture.
- Plan social timing: Even mild swelling matters if you have a major event.
- Follow aftercare closely: Pressure, heat, and strenuous activity may need temporary limits depending on treatment.
Safety literacy matters more in this area than many people realize
The nasolabial fold area appears frequently in complication datasets, which is one reason injector technique and product choice matter so much. One retrospective study of dermal filler complications found that nasolabial folds were the most common complication site at 37%, ahead of the nose at 22.2% and chin at 14.8%, according to the review of filler complications and PCL safety.
For hyaluronic acid fillers used in this area, a pooled review found an overall complication incidence of 58%, with commonly reported issues including lumpiness 43%, tenderness 41%, swelling 34%, bruising 29%, pain 28%, and redness 26%, while pooled infection and vascular adverse event rates were both 1%, as detailed in the meta-analysis of HA filler complications in nasolabial folds.
That doesn't mean treatment is unsafe. It means patients should understand that “complication” often includes mild, temporary effects, and that this anatomic area deserves careful planning.
Ask not only “Will this soften the line?” but also “Why is this the safest match for my anatomy?”
Combining Treatments for Natural Lasting Improvement in Laugh Lines
The best laugh lines treatment often looks less dramatic on paper than on the face. That's because natural improvement usually comes from stacking small corrections in the right order instead of pushing one treatment too far.
A common sequence is to restore support first, then improve the surface. If cheek flattening or tissue descent is driving the fold, treating lift or volume before chasing fine texture usually makes more sense. Once the structure is improved, PRP, PRF, microneedling, or skin-focused treatments can refine the result.
Examples of combination logic
- Midface support plus fold refinement: Useful when the fold is partly a cheek problem and partly a crease problem.
- PDO threads plus conservative filler: Helpful when tissue descent is making the fold look heavier.
- Filler plus PRP or PRF: A good match when you want both structural improvement and better skin quality.
- Threads plus microneedling or RF microneedling: Often chosen when laxity and texture are showing up together.
Results also appear on different timelines. Fillers can soften quickly. Threads may show an early lifting effect with gradual collagen support. Regenerative treatments usually ask for more patience because skin quality changes tend to build over time.
That's why maintenance should be planned, not improvised. If you know whether your main goal is reversibility, durability, lift, or skin improvement, your treatment plan becomes much easier to design and adjust. For many adults in Williamsport, the most satisfying result isn't a perfectly erased laugh line. It's a face that looks less heavy, less tired, and still natural.
Medical Aesthetics And Lasers in Williamsport offers physician-led evaluation for laugh lines treatment using options such as dermal fillers, PDO thread lifts, PRP, PRF, microneedling, and other skin-rejuvenation approaches matched to facial anatomy and treatment goals. If your folds seem deeper because of volume loss, laxity, or changing skin quality, a personalized plan can help you choose the right combination rather than over-treating one line.
