Nasolabial folds

It is the junction where the cheek's fat compartments meet the tissue of the upper lip, held by a ligament. On a young face the cheek sits high and full above that junction and the fold is a soft crease. As the cheek fat descends and the bone behind it resorbs, tissue piles up against the junction from above and the crease becomes a fold.

So the depth of the fold is largely a measure of how much has come down from above, not of anything happening in the fold itself.

If you inject product into the fold while the tissue above it is still descending, you have added weight to a heavy area. The fold may look shallower immediately, but the lower face reads as fuller and more pulled-down, and the effect tends to look worse in photographs than in a mirror.

It is also the treatment most likely to produce the look people are actively trying to avoid — the slightly swollen, slightly changed lower face that reads as work having been done.

This is one of the most common corrections I am asked about, and it is usually solved by dissolving and replanning rather than by adding more.

Placing structural support higher — over the cheekbone and in the midface, where bone and ligament support has been lost — lifts the tissue away from the fold and softens it at source. Very often that is all that is needed, and it uses less product than filling the fold would have.

It also improves several things at once: the fold, the flattening across the cheek, and often the hollow under the eye, all of which have the same underlying cause.

Sometimes, in small amounts, and afterwards. Where midface support has been restored and a residual crease remains — because it has been etched into the skin over decades — a very small amount of a soft product placed correctly can refine it.

The order matters. As a refinement it works. As a first move it usually does not.

If a clinic offers to treat your nasolabial folds without assessing your midface, that tells you something about how they plan treatment.

Where the fold has become a fixed line in the skin as well as a structural fold, skin-quality treatment improves the etched part. Microneedling and skin boosters both help.

Structure first, then skin, is generally the right sequence — improving the skin over tissue that is still unsupported gives a smaller return.

Five things drive the change, they usually run together, and only one of them has its answer in the fold itself. Working out which is dominant for you is most of what a consultation is for — it decides whether the treatment goes in the cheek, in the skin, or nowhere at all.

Why this is a high-risk region

The facial artery and its branches run close to the nasolabial fold, and the vessels above it connect toward the blood supply of the eye. This is one of the two areas of the face where a vascular occlusion carries the most serious consequences, which is why depth, technique and knowing when not to inject matter more here than almost anywhere else.

That is a reason to ask directly what training the person holds and whether hyaluronidase is kept on site — not a reason to avoid the area, which is treated safely and routinely by people who know it well.

What good practice looks like

Aspiration or a cannula where the technique calls for it, slow placement, small volumes, and a practitioner willing to stop and reassess rather than finish the syringe. Anyone treating this area briskly is treating it as though it were the cheek.

The third row is the one that needs saying out loud at consultation. Where laxity is the dominant problem, more product produces a heavier face rather than a smoother one, and the honest conversation is about skin tightening or a surgical opinion instead.
