Best Treatments for Nasolabial Folds: Filler, Biostimulators, and Energy Devices Compared

Nasolabial folds are the two creases that run from the sides of your nose down to the corners of your mouth. Almost everyone has them, and almost no single treatment erases them, because the fold is the product of several different aging processes happening at once. This guide walks through what actually causes the fold, then grades the real evidence behind fillers, biostimulators, energy devices, and threads so you can match a treatment to the part of the problem you actually have.

What Nasolabial Folds Actually Are

The nasolabial fold is not a wrinkle in the usual sense. It is the boundary line where the cheek tissue ends and the upper lip begins. You are born with a faint version of it. It deepens with age for reasons that have little to do with the crease itself.

Three changes stack up over time. First, the deep fat pads in the midface deflate, so the cheek loses its forward projection and the tissue above the fold sags down toward it. Second, the retaining ligaments that anchor the skin to deeper structures stretch and weaken, letting the cheek slide down and pile against the fold line. Third, the bone of the upper jaw and the rim around the eye socket lose volume, removing the scaffold that once held everything up. Skin changes pile on top: less collagen, fragmented elastin, less of the skin's own hyaluronic acid.

Why does this matter for treatment? Because a fold driven mostly by cheek descent needs different work than a fold driven mostly by a sharp surface crease. The most common mistake is dumping filler straight into the crease when the real problem sits an inch higher, in the cheek. A good injector treats the cause, not just the line.

There is also a static-versus-dynamic distinction worth understanding. Some of the depth of a nasolabial fold is there even when your face is at rest — that is the static component, mostly volume and skin. Some of it appears only when you smile or talk, as the muscles around the mouth pull the cheek tissue and crease the line — that is the dynamic component. Treatments that add or rebuild volume help the static part. They do little for the dynamic part, which is one reason a heavily animated face keeps a visible fold no matter how much filler goes in. This is also why neuromodulators like botulinum toxin sometimes get added to a plan: not to fill the fold, but to soften the muscle pull that deepens it. On their own, though, neuromodulators are a weak tool for the nasolabial fold and are not a primary treatment.

One more reality check: photographs lie a little. Lighting from above casts a shadow into the fold and makes it look deeper than it feels in person. Before spending money chasing a number on a severity scale, it helps to look at yourself in flat, even light and decide how much the fold actually bothers you in normal life.

The grading system used here

Throughout this guide, evidence is graded honestly:

• Strong: multiple randomized controlled trials (RCTs) plus regulatory approval for this exact use.
• Moderate: at least one good RCT or consistent comparative studies, but gaps remain.
• Weak/Mixed: small studies, no blinding, short follow-up, or conflicting results.

A treatment can be popular and still sit at "weak." Popularity is not proof.

Treatment Options Compared

Here is the short version before the deep dives. Read the rest of the article before acting on any single row.

Prices vary widely by city and provider. Treat these as ballpark figures, not quotes.

Dermal Fillers (Hyaluronic Acid)

How it works

Hyaluronic acid is a sugar molecule your body already makes. Injected as a gel, it physically fills space and draws in water, lifting the crease or, more often, restoring the cheek volume above it. It is the default first-line treatment for a reason: it works immediately, it is adjustable, and it can be dissolved with an enzyme called hyaluronidase if you don't like the result or if something goes wrong.

The evidence

This is the most studied option, and the evidence is strong. Multiple randomized, blinded trials show meaningful, reproducible improvement on the Wrinkle Severity Rating Scale (WSRS), a 5-point scale where lower is better.

In one randomized, evaluator-blinded split-face study, a novel HA filler matched the established product Restylane SubQ, with mean WSRS improvement from baseline at week 24 of 1.85 versus 1.88 — essentially identical — and that benefit held through week 48 (Hong et al., Dermatol Surg 2018, PMID 29543617). Other randomized, double-blind, self-controlled trials report similar safety and efficacy over 24 to 52 weeks (Wu et al., J Dermatolog Treat 2023, PMID 37694979; Dermatol Surg 2024, PMID 38713883).

It is worth knowing why split-face designs show up so often in this research. Each person serves as their own control: one fold gets product A, the other gets product B or stays untreated, and blinded evaluators score photos without knowing which side is which. That design controls for the huge person-to-person variation in skin and aging, which is why these trials are more trustworthy than before-and-after galleries. The flip side is that most of them run 6 to 12 months, so they tell you the product works in the short term but say less about how it ages at two years.

Honest limits

HA does not last forever. Real-world duration in the nasolabial area runs roughly 6 to 12 months for many patients, sometimes longer with newer thicker gels. Heavy folds may need one to two syringes. And filler corrects volume — it does not tighten loose skin. Pump too much directly into a deep fold and you can get a heavy, overfilled look that ages poorly.

There is also a less obvious limit. HA filler draws water, so it can swell, and in thin-skinned areas near the fold that can read as puffiness rather than correction. Repeated overfilling year after year is how some people end up with the heavy, distorted midface that gets mocked online. The fix is restraint: treat the cheek support first, add a small amount along the fold only if needed, and stop. A conservative result that you maintain beats an aggressive one you regret. Because HA is reversible, an honest provider should be willing to dissolve and start over if the proportions look off.

Biostimulators (Sculptra and Radiesse)

Biostimulators don't just fill space. They prompt your own fibroblasts to lay down new collagen, so the result builds over months and, in theory, lasts longer.

Poly-L-lactic acid (Sculptra)

Sculptra is poly-L-lactic acid (PLLA), a material that triggers a slow, controlled collagen response. It is FDA-approved for nasolabial fold correction (approved in 2009 for this aesthetic use). You typically need two to three sessions spaced weeks apart, and results appear gradually rather than the same day.

The evidence here got noticeably stronger recently. A 2026 multicenter, double-blind, randomized trial in 252 patients compared PLLA microspheres head-to-head against HA filler for moderate-to-severe folds. At 48 weeks, PLLA produced a significantly higher effective correction rate than HA (92.4% versus 59.3%). The honest nuance: HA worked better at week 4 because of its immediate fill, while PLLA only pulled ahead from about week 36 onward as collagen built up. PLLA also needed more early sessions (Wang et al., Aesthet Surg J Open Forum 2026, PMID 41694326). That trade-off — slower start, more durable finish — is the real story, not "Sculptra beats filler."

Calcium hydroxylapatite (Radiesse)

Radiesse is calcium hydroxylapatite (CaHA) microspheres suspended in a gel. It is FDA-approved for moderate-to-severe nasolabial folds (approved 2006). Unlike Sculptra, it gives an immediate lift from the gel carrier, then stimulates collagen as the microspheres dissolve. Evidence is moderate: it has regulatory backing and supportive studies, but fewer high-quality head-to-head trials in the fold specifically.

A 2026 systematic review of both PLLA and CaHA biostimulators in the face concluded they are effective and durable with acceptable safety, while noting that study quality and direct comparisons remain limited (Aesthetic Plast Surg 2026, PMID 41184662). That is a fair summary: the category works, but the literature is thinner and messier than the marketing suggests.

One practical difference between the two: Radiesse can be diluted or "hyperdiluted" to behave more like a collagen-stimulating treatment spread over a broad area, rather than a focused volumizer. That technique is popular but rests on more clinical experience than rigorous trial data, so file it under "promising and widely used" rather than "proven by RCT." Both biostimulators also depend on your own biology — younger patients with more responsive fibroblasts tend to build more collagen than older patients, which is part of why results vary so much person to person.

Honest limits

Biostimulators are not reversible the way HA is — there is no quick dissolve. Results depend heavily on injector technique. Sculptra carries a known risk of small bumps or nodules if not massaged and diluted properly. And the "lasts years" claims you see online outrun the rigorous data, which mostly tops out around 18 to 24 months of measured follow-up.

Energy Devices (Radiofrequency, Ultrasound, Lasers)

Energy devices heat the deeper skin to tighten existing collagen and trigger new collagen. They are marketed hard as a "no-needle" or "no-filler" fix for folds. The evidence does not fully support that framing.

Radiofrequency

RF and microneedling RF deliver heat into the dermis. For the nasolabial fold specifically, the evidence is weak to moderate. One randomized single-blind trial of non-ablative RF (with or without low-level laser) found significant aesthetic improvement in facial wrinkles immediately and at follow-up, but several measured endpoints did not change throughout the study — a mixed result, not a clean win (Pinheiro et al., J Cosmet Laser Ther 2017, PMID 27997267).

Where RF is more convincing is for skin laxity and texture, and as a combination with filler rather than a standalone fold eraser. If your fold is driven by a sharp crease and good volume, RF may help. If it is driven by descended cheek volume, RF alone will disappoint.

Lasers

A small study of an "endolift" fiber laser reported reduced depth and area of nasolabial wrinkles with measurable increases in skin density on ultrasound (Efficacy of endolift laser, PMC10523256). Promising, but it is a small, lower-tier study. Resurfacing lasers improve the skin's surface and fine lines, not the underlying volume loss that creates a deep fold.

Ultrasound (Ultherapy)

Microfocused ultrasound lifts mild tissue laxity. It can soften an early fold by lifting the cheek, but it is not a strong fold treatment on its own and results are subtle. For a deeper analysis of the ultrasound evidence, see our Ultherapy evidence review. If you want the broader picture on heat-based skin tightening, our radiofrequency skin tightening guide covers how these devices are supposed to work and where they fall short.

Threads

Thread lifts use dissolvable sutures (often PDO) with tiny barbs or cogs to physically reposition sagging cheek tissue and trigger some collagen. For the nasolabial fold, the evidence is weak to moderate: studies show real but often modest and short-lived improvement, and effects are best when combined with other treatments.

A prospective study found that adding botulinum toxin to PDO cog threads enhanced and prolonged fold correction. That is informative — but it also tells you threads alone were not enough. Thread complication rates (asymmetry, visible threads, dimpling) are non-trivial, which is why this stays a second-tier option for most folds. You can review the broader rejuvenation evidence in the PDO thread lift literature on PubMed.

Surgery: The Honest Benchmark

For folds driven mainly by significant cheek descent and loose skin, no injectable or device matches what a facelift does, because surgery physically repositions the tissue and removes the excess. It is the one option with decades of strong outcomes for true laxity. It is also the most expensive, the most invasive, and the slowest to recover from. Most people with mild to moderate folds do not need it. People with heavy jowling and deep folds who keep chasing the result with filler often would have been better served by surgery.

Matching the Treatment to the Cause

The takeaway: the fold is usually a cheek problem, not a crease problem. Treating the cheek is more natural-looking and more durable than packing the line.

A realistic combination plan

In practice, the best results often come from combining tools rather than betting everything on one. A common sensible sequence looks like this: restore midface support first (cheek filler or a biostimulator), reassess the fold after the swelling settles, then add a conservative touch directly along the crease only if it is still bothersome. If skin laxity is part of the picture, an energy device can be layered in for skin quality. The order matters — lifting the cheek often shrinks the fold enough that you need far less product in the line itself, which saves money and looks more natural. Beware the provider who reaches straight for the syringe at the fold without ever examining your cheek. That is treating the symptom.

Combination care also means spacing things out. There is no prize for doing everything in one visit. Letting filler settle, or letting a biostimulator build collagen over a few months, gives you a true baseline before you decide whether more is needed. Patience is cheaper than corrections.

The Evidence, Side by Side

To keep the grading honest, here is the bottom line on what the research actually supports versus what the marketing claims.

Notice the pattern. The treatments with the strongest, most reproducible evidence — HA filler and PLLA — are the ones that directly address volume, which is the main driver of most folds. The energy and thread options have weaker fold-specific evidence and shine mainly as supporting players for skin quality and mild laxity. That does not make them useless. It makes them poorly matched to a deep, volume-driven fold, which is exactly the situation most people are trying to fix.

Safety: What to Take Seriously

The nasolabial fold sits near the angular artery, and this is the part of cosmetic injecting that deserves genuine respect. Filler accidentally injected into or compressing a blood vessel can cause skin death (necrosis) and, in rare but documented cases, vision loss or blindness when filler travels backward into vessels connected to the eye (Vascular complications review, MDPI Diagnostics 2024, PMC11276034).

These events are rare. They are also catastrophic and can be permanent. This is exactly why provider choice matters more than product choice. Practical safety rules:

• Choose an experienced, licensed injector (physician, NP, or PA) who knows facial vascular anatomy.
• Make sure hyaluronidase is on-site to reverse HA filler in an emergency.
• Know the warning signs: severe pain out of proportion, sudden blanching or dusky/white skin, vision changes — all require immediate attention.
• Biostimulators cannot be dissolved, so injector skill matters even more with Sculptra and Radiesse.

Common, milder side effects across injectables include bruising, swelling, tenderness, and occasional lumps. Energy devices can cause redness, swelling, and rarely burns or temporary numbness.

A word on where you get treated. The same product injected by a rushed, undertrained provider in a non-medical setting carries far more risk than it does in a properly run medical practice. Ask who is actually performing the injection and what their training is. Ask whether a physician is on-site or reachable. Ask what happens if there is a complication after hours. Cheap injectables are not a bargain if the safety net underneath them is missing. Price-shopping makes sense for a haircut; it is a poor strategy for something injected millimeters from the arteries that feed your eye.

It also helps to set expectations for the first 48 hours. Bruising and swelling are normal and usually peak the day after, then fade over several days to two weeks. Arnica and cold compresses may help with bruising, and avoiding alcohol, blood thinners, and strenuous exercise right before and after reduces it. What is not normal — and warrants an urgent call — is pain that keeps climbing, skin that turns white or mottled blue, or any change in vision.

Who Each Option Is For

• You want fast, reversible, predictable results: HA filler.
• You want gradual, longer-lasting volume and don't mind multiple sessions: Sculptra (PLLA).
• You want lift with some immediate effect: Radiesse (CaHA).
• Your main issue is mild skin laxity or texture, not volume: RF or RF microneedling.
• You have heavy sagging and loose skin: talk to a facial plastic surgeon before spending thousands on injectables that can't fix laxity.

If you are weighing biostimulators against standard filler more broadly, our biostimulator vs filler comparison breaks down the trade-offs, and the Sculptra vs Radiesse comparison digs into the two main biostimulators side by side. For folds that overlap with cheek hollowing, the cheek filler cost and placement guide explains why injecting the cheek often fixes the fold better than injecting the fold itself.

Frequently Asked Questions

Can fillers completely get rid of nasolabial folds?

No, and a provider promising that is overselling. Fillers soften and reduce the fold, often dramatically, but the crease is a normal facial landmark that everyone has. Erasing it entirely usually means overfilling, which looks unnatural and ages badly. Realistic goal: a softer, less shadowed fold, not a flat face.

How long do the results last?

It depends on the treatment. HA filler typically lasts about 6 to 12 months in the fold area. Biostimulators like Sculptra can last up to roughly two years but build slowly and need multiple sessions. Energy devices and threads give shorter, more variable results and usually need repeating. The 2026 head-to-head trial found PLLA outlasted HA by 48 weeks, but HA worked faster early on.

Are biostimulators better than regular filler?

Not universally — it's a trade-off. The strongest recent trial showed PLLA (Sculptra) produced more durable correction than HA at 48 weeks (92.4% vs 59.3% effective correction), but HA worked better in the first month and is reversible. Biostimulators can't be dissolved if you dislike the result, so they demand a more skilled injector.

Do at-home radiofrequency or "lifting" devices work on folds?

Barely, if at all, for a true fold. At-home RF can mildly improve skin texture and very mild laxity over months of consistent use, but it cannot replace lost cheek volume, which is the main driver of most folds. The evidence for at-home devices on deep folds specifically is weak. Manage expectations accordingly.

What is the safest option?

HA filler is generally considered the most forgiving because it is reversible with hyaluronidase if a problem occurs. But safety depends far more on the injector than the product. The nasolabial area carries a rare risk of vascular complications including skin necrosis and, in extreme cases, vision loss — which is why an experienced, medically qualified provider with emergency reversal on hand matters most.
