Nasolabial fold filler is a hyaluronic-acid filler treatment that softens the natural lines running from the side of your nose down to the corner of your mouth. The product adds gentle volume above and around the line, supports the cheek tissue that has descended over time, and reduces the depth of the fold. Results are immediate, last 9 to 18 months, and look natural when the filler is placed conservatively.
I am Cristina Pardo, an NMC-registered aesthetic nurse practitioner in Norwich. This post walks through who is a good candidate for nasolabial fold filler, what the treatment actually involves, and the cases where I would steer a client toward a different treatment instead.
What nasolabial folds actually are
Everyone has nasolabial folds. They are the natural boundary between the cheek and the area around the mouth. In a younger face they tend to be invisible because the cheek tissue sits high and the surrounding skin is taut. As we age, the cheek tissue descends, the area around the mouth loses volume, and the boundary between the two becomes more visible. The result is the lines most clients call smile lines.
The folds usually deepen unevenly. Most people see one side become more pronounced than the other, often correlating with the side they sleep on. Smokers and people who spend significant time outdoors tend to see deeper folds earlier.
It is worth being honest about something here: the nasolabial folds are an anatomical feature, not a flaw. Eliminating them entirely creates an unnatural, slightly tight look. The goal of filler is to soften the depth, not to remove the structure.
Who suits nasolabial fold filler
Clients with moderate folds where the surrounding skin still has reasonable elasticity. The product needs structure to integrate with, and very lax skin does not give the filler enough support to work well.
Clients who have already considered cheek filler. In many cases, restoring volume to the cheek itself partially lifts the nasolabial fold from above, reducing the need for filler in the fold area. I often recommend treating the cheek first and reassessing the fold afterwards.
Clients who want a natural, conservative result and are open to a small amount of product (typically 1ml across both sides). One ml of filler placed correctly does more than 2ml placed aggressively.
Who does not suit it
Clients with very deep folds and significant skin laxity. Filler alone in these cases tends to look heavy and uneven. A combination approach (Profhilo or polynucleotides to improve skin quality, then a small amount of filler) usually works better.
Clients whose primary concern is the marionette lines (the lines running down from the corner of the mouth) rather than the nasolabial folds themselves. The two get confused often. Marionette lines need a different treatment approach.
Clients who have had aggressive filler in the area previously. Old product can migrate, accumulate, and create a heavy appearance. In these cases I usually recommend dissolving the existing filler with hyaluronidase first and reassessing.
What the treatment actually involves
After the consultation, the in-person treatment runs around 30 to 45 minutes. I apply numbing cream first and let it work for 15 minutes while we go through the final consent and the plan. I mark the injection points carefully with a sterile pen.
Most nasolabial fold treatments use a small cannula rather than a needle. The cannula is a single-use, blunt-tipped instrument that reduces the risk of bruising and gives smoother product distribution. The entry point is a single small puncture near the corner of each mouth, and the cannula moves the product into the area beneath the fold.
You will see the result immediately, though some clients have slight asymmetry from swelling for the first 24 hours. Final result settles by day 7. I review by photo at 14 days.
What it looks like at 6 months and at 18 months
At 6 months: most of the result is still visible. The product integrates with surrounding tissue and the visual improvement holds.
At 12 months: gradual softening. The fold becomes more visible again but rarely returns fully to baseline.
At 18 months: most clients schedule a top-up. A smaller amount of filler (typically 0.5ml) maintains the result going forward.
Across multiple treatments over years, most clients find the cumulative effect is gentler than they expected. The face does not become heavier or fuller looking. The improvement is just maintained.
Frequently Asked Questions
Most clients need 1ml total across both sides for a first treatment. Sometimes 0.5ml is enough for very subtle softening. Anything over 2ml is rarely needed and starts to look heavy.
Mild discomfort, comparable to a pinch. I use numbing cream beforehand and the filler itself contains lidocaine. Most clients describe it as easy.
Typically 9 to 18 months depending on the product, the area, and your metabolism. The first treatment in a new area often integrates well and can last toward the longer end.
Not if dosed correctly. The goal is softening, not elimination. Conservative volume gives a natural improvement. Excessive volume creates a heavy upper lip area that looks treated.
Yes, with timing. I recommend 4 to 6 weeks before the date to allow swelling to settle and final result to show. Not less than 3 weeks.
Often yes. Cheek filler can lift the nasolabial area indirectly. I will assess and tell you honestly during the consultation. If cheek filler is the better answer, we start there.
