Nasolabial Fold Filler: Why the Answer Is Often Higher Up the Face

The nasolabial folds are the creases that run from the sides of the nose down to the corners of the mouth. Everyone has them, and they are part of a natural smile. With age they tend to deepen, and many people start to feel they look tired or older than they are.

Filler can soften these lines. But the most important thing to understand about nasolabial fold filler is that the fold is usually a symptom, not the cause. Treating the crease directly is sometimes right. Often the better result comes from treating somewhere else.

Why the folds deepen

Several things happen at once as the face ages:

Volume loss in the cheek. The fat pads of the mid-face thin and descend, so the cheek flattens and the tissue above the fold slides down against it.
Laxity. Skin and supporting tissue loosen, and gravity does the rest.
Skin quality. Collagen and elasticity decline, so creases form more easily and stay visible.
Bone changes. The bones of the mid-face gradually lose projection, reducing support for the soft tissue above them.

Genetics, sun exposure, smoking and weight changes all influence how early and how deeply the folds form. Weight loss in particular can make them look deeper by removing volume from the face.

Filling the fold, or supporting it from above

There are two broad ways to use filler for smile lines.

Treating the fold directly. A small amount of filler is placed along or beneath the crease to soften it. This can work well for a defined, relatively isolated line in someone whose cheeks still have good volume. The risk is that adding volume beside the mouth, where the face should be relatively slim, can make the lower face look heavy, particularly if the amount grows over repeated treatments.

Treating the cheek. For many people the more natural result comes from restoring lost volume in the mid-face. Supporting the cheek lifts the tissue that is folding over, and the nasolabial fold softens as a result. Cheek filler explains how that works and why it shows first when it is overdone.

Often a small amount in both places gives the best balance. The right plan depends on your anatomy, which is why an assessment of the whole face matters more than the fold itself.

What the treatment involves

A consultation comes first, looking at the face at rest and in motion. If filler is right for you, the skin is cleaned and often numbed, and a hyaluronic acid filler is placed with a fine needle or a blunt cannula. The treatment is usually short. Conservative amounts, reviewed after the swelling settles, look more natural than trying to erase the line entirely. A face with no smile lines at all looks unusual.

Recovery

Most people return to normal activities the same day. Swelling, tenderness and bruising are common and usually settle over several days. Avoiding strenuous exercise and pressure on the area for a short time afterwards helps, and your injector will give you specific aftercare instructions.

Risks worth knowing about

Bruising and swelling are the most common and usually temporary.

Lumps, unevenness or asymmetry can occur and can often be massaged or corrected.

Over-correction, a heavy or puffy look beside the mouth, is the most common aesthetic problem, and it often builds up gradually over repeated treatments.

Blockage of a blood vessel is rare but serious. The area beside the nose has an important blood supply. Sudden pain, blanching, mottled or darkening skin, or any change in vision after an injection needs immediate medical attention.

Hyaluronic acid filler can usually be dissolved with an enzyme called hyaluronidase if there is a problem.

Marionette lines

The lines that run down from the corners of the mouth toward the chin, called marionette lines, often appear alongside deep nasolabial folds and have similar causes. They can be softened with filler too, and are often treated in the same session. The same principle applies: support the structure around them rather than simply filling the crease.

When surgery is the better answer

If the folds are mainly caused by sagging tissue rather than lost volume, filler cannot lift what has descended, and adding more of it to compensate tends to look heavy. In that case a facelift or mid-face lift repositions the tissue itself. Deep plane facelift explains how that works, and facelift vs mini facelift covers the difference in scope. Longer-acting volume can also come from Sculptra or fat transfer, depending on your goals.

The short version

Nasolabial fold filler can soften smile lines, but the fold is usually a sign of volume loss or descent higher on the face. For many people, restoring the cheek gives a more natural result than filling the crease, and a small amount in both places often works best. Keep the amounts conservative, choose an experienced injector who assesses the whole face, and consider surgery when sagging rather than volume is the main problem.

Find out what is deepening the fold

A consultation looks at whether your smile lines come from lost cheek volume, skin quality or sagging, and whether filler, a treatment higher on the face, or surgery is the right answer for you.

Request a Consultation

The creases that run from the sides of the nose to the corners of the mouth, often called smile lines or laugh lines. Everyone has them to some degree, and they tend to deepen with age.

It can soften them. For many people, though, restoring volume in the cheek above the fold gives a more natural improvement than filling the crease itself. A consultation is the way to find out which suits you.

Because the fold is often caused by volume loss and descent higher on the face. Adding filler directly into the crease can make the area beside the mouth look heavy or puffy, especially if too much is used.

Most people feel pressure and some stinging. Numbing cream is commonly used and many fillers contain a local anesthetic. The appointment is usually short.

It varies with the product, the amount used and the person. Your injector can tell you what to expect for the product they recommend.

Bruising, swelling and tenderness are common. Lumps and asymmetry can occur. Rarely, filler can block a blood vessel, which is a medical emergency; the area beside the nose has important vessels, so experience matters. Hyaluronic acid filler can usually be dissolved if needed.
