Nasolabial folds are the smile lines running from the sides of the nose to the corners of the mouth. Learn what causes them, how to slow them, and the filler, biostimulator, and thread options that soften them.
Nasolabial folds are the creases running from the sides of your nose to the corners of your mouth, often called smile lines or laugh lines. They deepen with midface volume loss, collagen decline, cheek sagging, and repeated smiling. Hyaluronic acid fillers are the most common treatment, restoring lost support.
FDA status, stated plainly: hyaluronic acid dermal fillers such as Juvederm and Restylane are FDA-approved to correct moderate to severe nasolabial folds, and poly-L-lactic acid (Sculptra) and calcium hydroxylapatite (Radiesse) are also FDA-approved for this area. Botox is not FDA-approved for nasolabial folds, and using it there is off-label. This guide is educational and is not a substitute for a consultation with a licensed provider.
Nasolabial folds are one of the most searched aesthetic concerns because nearly everyone develops them, yet they are not a flaw or a disease. They are normal facial anatomy that becomes more visible as the midface changes with age. The realistic goal of treatment is to soften a fold, not to erase a natural feature of the face, and the right approach depends on whether your folds come mainly from lost volume, sagging tissue, or a deep static crease.
Nasolabial folds are the two creases that run from the sides of the nose down to the outer corners of the mouth. They mark the boundary between the cheek and the upper lip, and clinicians consider them part of normal facial architecture rather than a problem to be fixed. In everyday language people call them smile lines or laugh lines because they deepen when you smile, laugh, or talk. They are present in almost everyone to some degree, become more noticeable with facial expression, and are absent only in the newborn face and the fully relaxed or paralyzed face.
It helps to separate two things that often get grouped together. The fold itself is the crease, and the nasolabial region is the pad of cheek tissue that sits above and outside it. As that cheek pad loses volume and drifts downward, it presses against the fixed line of the fold and makes the crease look deeper. Nasolabial folds are also distinct from marionette lines, which run from the corners of the mouth toward the chin, and from perioral lip lines. Understanding which crease bothers you matters because the treatment and the injection target differ for each.
Nasolabial folds form from a combination of anatomy, aging, and lifestyle, not from a single cause. Anatomically, the fold sits where dense fibrous tissue and small muscle fibers anchor the skin to deeper structures, so a faint line exists even in young faces. Peer-reviewed anatomical studies describe three overlapping drivers: volume deficiency, tissue laxity, and muscular attachment. That is why one person can have a shallow fold from mild volume loss while another has a deep, set crease from heavier sagging.
Aging is the dominant factor. From the mid twenties onward the skin steadily loses collagen and elastin, so it becomes thinner and less springy and holds a crease more readily. At the same time the cheekbones and the facial fat pads change: the malar fat descends, the underlying bone remodels and flattens slightly, and gravity pulls loose tissue downward. This sagging of the upper cheek is a well documented contributor to nasolabial fold formation, because the descending cheek stacks on top of the fixed fold line.
Lifestyle and environment accelerate the process. Ultraviolet exposure is the single largest preventable cause because it breaks down collagen and elastin through photoaging. Smoking destroys the same fibers and starves the skin of oxygen, deepening folds earlier. Repeated expression, sleeping position, significant weight loss that leaves loose skin, weight gain that enlarges the cheeks, and genetics all shape how early and how deeply the folds appear. Most people carry several of these factors at once, which is why folds usually reflect a mix of causes rather than one.
Nearly everyone develops nasolabial folds because they are built into normal facial anatomy. A soft version is visible in childhood whenever a person smiles, and a faint resting line is common by the late twenties. Around the ages of 25 to 30, many people first notice that the crease lingers slightly even when their face is at rest, which reflects the earliest collagen decline rather than advanced aging. This is a normal timeline, not a sign that something is wrong.
The folds typically become more defined through the thirties and forties as midface volume loss and skin laxity add up, and they often deepen further in the fifties and beyond. Timing varies widely from person to person. People with fair, sun-exposed skin, smokers, those who have lost significant weight, and those with a genetic tendency toward earlier volume loss tend to see deeper folds sooner. Bone structure also matters: flatter cheekbones or a more forward-projecting midface can make the same crease look more prominent. Because the pattern is so individual, the age a fold appears says little about a person's overall skin health.
You cannot prevent nasolabial folds entirely because they are part of facial anatomy, but you can meaningfully slow how quickly they deepen by protecting collagen. Daily broad-spectrum sunscreen is the most effective single habit, since ultraviolet light is the leading preventable driver of collagen breakdown. Reapplying sunscreen, wearing a hat, and avoiding tanning all reduce photoaging over the years, and this protection compounds the earlier you start.
A consistent skincare routine adds modest but real benefit. Topical retinoids are the best-studied ingredient for building collagen over months and thickening the skin so it creases less readily, and antioxidants such as vitamin C help defend against daily oxidative damage. Keeping the skin barrier hydrated makes fine lines look softer, though moisturizer alone does not reverse an established fold. Not smoking preserves the collagen and elastin that smoking actively destroys, and stable body weight avoids the loose skin that follows large swings.
Be realistic about what prevention can do. These habits slow the trajectory and keep early folds shallow, but they will not erase a deep, set crease, and no cream, facial exercise, or massage has strong evidence for eliminating an established nasolabial fold. Treat prevention as long-term maintenance that protects your results if you later choose an in-office treatment, rather than as a cure.
Because nasolabial folds come from volume loss, laxity, and a fixed crease, the best treatment depends on which of those dominates. Injectable treatments address the volume and support that most folds need, while energy devices and surgery address skin quality and heavier sagging. A skilled provider often treats the cheek that sits above the fold rather than only the crease itself, because lifting and supporting the midface reduces the pressure that deepens the line.
Hyaluronic acid fillers such as Juvederm and Restylane are the most common option and are FDA-approved for moderate to severe nasolabial folds. They add immediate, reversible volume that can be dissolved with hyaluronidase if needed, and results typically last several months to well over a year. Poly-L-lactic acid (Sculptra) is a biostimulator that is FDA-approved for this area and works gradually over a series of sessions by prompting your own collagen, with effects that can last up to two years. Calcium hydroxylapatite (Radiesse) is also FDA-approved for nasolabial folds and adds volume while stimulating collagen. Botox is not FDA-approved for nasolabial folds; injecting it into this area to relax muscle is off-label and generally a supporting role at most, not a primary fix. For heavy folds driven by sagging skin, energy-based skin tightening, thread lifts, or a surgical facelift may be more appropriate than filler alone, and those are procedures to discuss with a qualified provider.
Treatment options at a glance:
| Treatment | How it works | FDA status for nasolabial folds | Typical duration |
|---|---|---|---|
| Hyaluronic acid filler (Juvederm, Restylane) | Adds reversible volume to lift the fold | FDA-approved | Several months to 18+ months |
| Poly-L-lactic acid (Sculptra) | Stimulates your own collagen over a series | FDA-approved | Up to about 2 years |
| Calcium hydroxylapatite (Radiesse) | Adds volume plus collagen stimulation | FDA-approved | About 12 to 18 months |
| Botox in the fold | Relaxes nearby muscle, limited effect | Off-label (not approved here) | 3 to 4 months |
| Energy devices, threads, facelift | Tighten or reposition sagging skin | Varies by device or procedure | Months to years |
With hyaluronic acid filler, the change is visible immediately: the fold looks softer and the cheek looks more supported as soon as the product is placed. Mild swelling and firmness are common for the first few days and settle within a week or two, so the true result is best judged around two weeks out. Fillers soften a fold rather than erase it, and a natural-looking correction usually leaves a faint line rather than a completely flat area, which is the honest and safer goal.
Biostimulators behave differently. Sculptra and Radiesse build results gradually, so you should expect improvement to appear over several weeks and to deepen across a series of sessions rather than all at once. That slower timeline suits people who want a subtle, collagen-driven change, but it requires patience and usually more than one appointment. No injectable is permanent, and no honest provider can guarantee a specific outcome, because results depend on your anatomy, the severity of the fold, the product used, and the injector's technique.
Longevity varies. Thinner hyaluronic acid products used for fine correction tend to fade sooner than robust products placed for structural support, and factors such as metabolism, the treated area's movement, and how much product was used all affect how long results last. Most people return for maintenance, and planning for repeat treatment rather than expecting a one-time fix leads to more realistic satisfaction.
Dermal fillers are prescription medical devices, and while serious problems are uncommon in trained hands, real risks exist and deserve plain description. Common, expected side effects include redness, swelling, tenderness, bruising, and small lumps at the injection site, which usually resolve within days to a couple of weeks. Firmness or visible product can occur if too much is placed or the filler sits too superficially, and with hyaluronic acid this can often be corrected by dissolving it with hyaluronidase.
The most serious risk specific to the nasolabial region is vascular occlusion, where filler is inadvertently injected into or compresses a blood vessel. The nasolabial and nearby areas contain vessels connected to the eye, so an occlusion can, rarely, cause skin death (necrosis) or, very rarely, vision loss. This is why injector training and anatomical knowledge matter so much, and why fillers should be placed only by a licensed, experienced medical provider who can recognize and manage a complication immediately. Warning signs during or after treatment include severe or increasing pain, blanching or dusky skin color, and any vision change, all of which are medical emergencies.
Other considerations include infection, allergic reaction, delayed inflammatory nodules, and the movement or asymmetry of product over time. The FDA warns against fillers bought or injected outside a licensed medical setting and against needle-free filler devices sold online. Choosing a qualified provider, disclosing your full medical history and medications, and following aftercare instructions are the strongest ways to keep the procedure safe.
The cost of treating nasolabial folds varies widely, and injectables are elective cosmetic procedures that health insurance does not cover. Rather than quote a single number, it is more useful to understand what drives the price so you can judge a quote fairly. Hyaluronic acid filler is commonly priced per syringe, and the total depends on how many syringes your correction needs, which relates directly to how deep your folds are and whether the cheek above them also needs support.
Several factors move the price. The type of product matters, since biostimulators like Sculptra and Radiesse are often priced per vial or per session and typically require a series, while hyaluronic acid is priced per syringe. Geographic location and the cost of living in your city influence rates, as does the injector's credentials and experience, with board-certified physicians and highly experienced injectors often charging more. Because results are temporary, the honest way to think about cost is as an ongoing maintenance expense over the years, not a one-time purchase.
Be cautious of prices that seem far below the local norm, because unusually cheap filler can signal diluted product, an untrained injector, or an unlicensed setting, all of which raise safety risk. A transparent consultation should give you a written plan and a clear estimate before anything is injected.
You never need to treat nasolabial folds for medical reasons, since they are a normal feature of the face. Seeing a provider makes sense when the folds bother you enough that you want to understand your options, when you are unsure whether your folds come mainly from volume loss or from sagging skin, or when at-home skincare is no longer giving you the result you want. A consultation is also the right step if you have tried filler before and were unhappy, because technique and product choice vary a great deal between injectors.
Choose a licensed medical provider who injects regularly, such as a board-certified dermatologist, plastic surgeon, or a qualified nurse or physician assistant working under medical supervision. Ask about their training, how they will treat the cheek as well as the fold, which product they recommend and why, and how they manage complications like vascular occlusion. Bring your medical history and a list of medications and supplements. A trustworthy provider will set realistic expectations, explain that the goal is to soften rather than erase, and never pressure you into more product than you need.
If you are ready to explore treatment, the next step is a consultation with a qualified injector who can assess your face in person and recommend the safest approach for your anatomy.
You can soften nasolabial folds significantly, but you cannot fully erase them, because they are part of normal facial anatomy. Hyaluronic acid fillers reduce their depth by restoring lost cheek volume, and biostimulators like Sculptra build collagen over time. Deep folds from sagging skin may need energy devices or surgery instead.
Filler is the better choice for most nasolabial folds. The folds come mainly from lost volume and sagging, which hyaluronic acid fillers directly restore, and fillers are FDA-approved for this area. Botox is not FDA-approved here and only relaxes muscle, so its off-label use plays a limited supporting role at most, not a primary fix.
A faint nasolabial line is normal at any age when you smile, and many people first notice the crease lingering at rest around ages 25 to 30 as collagen begins to decline. The folds usually become more defined through the thirties and forties. Timing varies with sun exposure, smoking, weight changes, and genetics.
Natural steps slow rather than fix folds. Daily sunscreen, not smoking, a stable weight, and topical retinoids and antioxidants protect collagen and keep early folds shallow. No cream, facial exercise, or massage has strong evidence for erasing an established fold, so natural methods work best as prevention and maintenance.
Nasolabial fold before-and-afters show softening, not erasure, using about 1 to 2 mL across both folds. Complete removal is not the goal and looks unnatural, since everyone has nasolabial folds. Many of the best results come from filling the cheek above the fold rather than the fold itself.
The fold deepens largely because the midface fat pad descends, so injecting only the crease can produce a heavy, overfilled upper lip area while the underlying cause remains. Experienced injectors often treat the cheeks first, reassess at four weeks, then place a smaller amount directly in the fold. Deep folds may need 1.5 to 2 mL plus cheek support, and even then a residual line usually remains, particularly if there is significant skin laxity or sun damage. Swelling and bruising resolve over 7 to 10 days; assess at four weeks. This zone sits near the angular artery and is one of the higher-risk areas for vascular occlusion, so choose an injector who keeps hyaluronidase on site.
Nasolabial folds are the two creases running from each side of the nose to the corners of the mouth. Everyone has them, from infancy, and they appear whenever you smile. They only become a cosmetic concern when age-related volume loss makes them visible at rest.
The fold sits where facial muscles attach to overlying skin, so it is a fixed anatomical boundary, not a wrinkle. It deepens with age because the malar fat pad descends and orbital and maxillary bone resorbs, so tissue from the cheek gathers above the crease. Sun damage, smoking, genetics and significant weight loss accelerate the process. Nasolabial folds are not the same as marionette lines, which run downward from the mouth corners to the jaw. Treatment usually combines filler placed in the cheek to restore midface support with a conservative amount in the fold itself, plus skin-quality treatments. Complete erasure is neither achievable nor desirable, since a face without any nasolabial fold looks unnatural.
Nasolabial fold filler typically costs $600-$1,800 per session: usually 1-2 syringes at roughly $600-$900 each. Deeper folds that also need cheek support cost more. Results last 9-18 months depending on the product, so most people re-treat about once a year.
By product: hyaluronic acid fillers (Juvederm Vollure or Ultra XC, Restylane Refyne or Defyne) run $600-$900 per syringe; Radiesse is $700-$900; Sculptra is $800-$1,000 per vial across two to three sessions, so $1,600-$3,000 for a course, though it can last 2+ years. Cost also depends on whether your injector treats the cheek as well: nasolabial folds are frequently a symptom of midface volume loss, and filling the crease alone can disappoint. One caution specific to this area: the facial artery runs alongside the fold, making it one of the recognized facial danger zones, so bargain pricing is a poor trade. Note that Radiesse and Sculptra cannot be dissolved.
Juvederm Vollure XC is the most commonly chosen filler for nasolabial folds and lasts up to 18 months. Other FDA-approved options include Juvederm Ultra XC (6-12 months), Restylane Lyft (the first filler FDA-approved for this area), Restylane Defyne for deeper folds, and Radiesse for lift plus collagen stimulation.
There is no single best filler; the right choice depends on fold depth, skin thickness, and how much the area moves. Vollure and the Restylane Refyne/Defyne line use flexible cross-linking that moves naturally with smiling, which matters in a highly mobile zone. Deep, structural folds often respond better to indirect treatment, restoring midface and cheek volume rather than injecting the fold itself, because filling a deep fold directly with a heavy product can look bulky. Radiesse and Sculptra last longer (12-24 months and 2+ years) but cannot be dissolved with hyaluronidase. The nasolabial area sits near the facial and angular arteries, where vascular occlusion is a real risk, so injector skill and anatomy knowledge matter more than the brand on the syringe.
Microneedling helps mildly, and mainly for early folds. It stimulates collagen that thickens and firms the skin around the fold, which can soften a shallow nasolabial line over a series of three to six sessions. It does not replace lost volume, so it will not erase a deep, established fold.
Nasolabial folds are mostly a volume and structural problem: midface fat pads descend, the underlying bone resorbs, and skin creases where tissue folds over. Microneedling only addresses the skin layer. Radiofrequency microneedling (Morpheus8, Genius, Vivace) reaches deeper and produces more tightening than traditional microneedling, and is a reasonable option for mild folds or for someone who does not want filler. Expect gradual change over three to six months, with maintenance roughly annually. For moderate-to-severe folds, filler, biostimulators, or surgery give far more visible improvement, and the published evidence for microneedling on deep folds specifically is limited. Combining approaches is common: filler for volume, microneedling for skin quality, spaced at least two weeks apart.
