Nasolabial folds — the lines that run from the sides of the nose down to the corners of the mouth — are one of the most common reasons people first consider dermal filler. They're also one of the most misunderstood treatments. Done well, the result is natural and refreshed; overdone, and it creates the heavy, stuffed look that puts people off filler entirely. Here's how nasolabial fold filler actually works, what realistic results look like, and when a different approach might serve you better.
What are nasolabial folds?
Nasolabial folds are a normal part of facial anatomy — everyone has them to some degree, and they become more visible with age as the cheeks lose volume and the overlying skin loses elasticity. When the midface deflates, the skin that used to sit high on full cheeks folds down and the crease deepens.
This matters for treatment: a nasolabial fold is often a symptom of midface volume loss, not just a wrinkle in the fold itself.
How nasolabial fold filler works — and the mistake many clinics make
The straightforward approach is to inject filler directly into the fold to fill it. This works for moderate folds, but it has a limit: injecting too much directly into the crease creates a heavy, unnatural look — the "pillow face" result people fear. The reason is that you're adding volume to a symptom, not the cause.
The better approach, especially for deeper folds, is to restore midface (cheek) volume first. Lifting the cheek reduces the fold from above, so less direct injection is needed — or sometimes none at all. A skilled injector assesses the whole face first, not just the fold. This is the principle behind full-face filler planning — you can read more on that in our cheek, jawline and chin filler guide.
What product is right for nasolabial folds?
Nasolabial folds need a filler with enough body to support the fold from within, but not so firm that it creates a hard ridge under the skin. The standard choice is a mid-density HA gel injected into the mid-to-deep dermis — soft enough to integrate naturally, firm enough to provide lift.
AOMA's facial filler range includes Deep Lines and Deep Lines Plus grades specifically suited to nasolabial folds, marionette lines, and other moderate-to-deep creases — with 20–25mg/ml cross-linked HA in 1ml and 2ml volumes, with or without lidocaine for comfort.
For deeper or more structural folds, a firmer gel or a PLLA biostimulator may be appropriate — see our types of dermal fillers guide for a full comparison.
Results and longevity
Results from nasolabial fold filler are immediate, settling fully over one to two weeks. Because this area has moderate movement (speaking, eating, smiling), HA typically lasts 9–12 months here — in line with the pattern we cover in how long dermal fillers last.
Realistic expectations: filler softens and reduces the fold — it doesn't erase it entirely. A natural result means the fold is still present (as it should be — it's a facial structure) but no longer dominates the face. A completely flat result often means over-filling.
When filler isn't the answer: PLLA and PDRN
For patients who want longer-lasting results or prefer a more gradual approach, PLLA biostimulators can stimulate collagen in and around the fold over months — with results lasting up to two years. For patients where the issue is more about skin quality (fine lines, surface texture) around the fold than depth, PDRN mesotherapy can improve the skin itself rather than adding volume. Neither replaces filler for a deep fold, but they're often better choices for early-stage lines or as maintenance.
Safety
Nasolabial folds are among the oldest and most established filler indications — they appear in the FDA's list of approved dermal filler uses for moderate-to-severe facial wrinkles and skin folds. As with all HA filler, use an FDA-approved product, a trained injector, and confirm the product is properly labeled and sealed.
Sourcing nasolabial fold fillers
For clinics and brands, the nasolabial fold category demands a reliable mid-density HA with smooth extrusion and consistent gel structure. AOMA's HA dermal filler range covers Derm Lines, Deep Lines, and Deep Lines Plus grades suited to this indication, all produced to medical standard with CE, ISO 13485, and SGS certification. Private-label customization — formula, packaging, concentration, lidocaine option — is available for distributors and brands.

FAQ
Does filler get rid of nasolabial folds completely? No — and it shouldn't. Nasolabial folds are a normal facial structure. The goal is to soften and reduce them to a natural degree, not flatten them entirely. Over-filling is what creates an unnatural result.
Is filler or Botox better for nasolabial folds? Filler. Botox relaxes muscles but doesn't add volume — nasolabial folds are a volume and structural issue, not a muscle-movement one. Botox won't soften a nasolabial fold the way filler can.
How long does nasolabial fold filler last? Typically 9–12 months with HA filler. PLLA biostimulators used in this area can last up to two years.
How much filler do I need for nasolabial folds? Usually 1–2ml total, sometimes alongside cheek filler to address midface volume loss at the same time. A thorough consultation should assess the whole face, not just the fold.
Can nasolabial fold filler look natural? Yes — when the amount is appropriate and, where needed, combined with cheek support. The natural-looking result softens the fold without creating a heavy or over-filled appearance.
