In short. Nasolabial folds run from the nose to the mouth corners, and everyone has them. They deepen as the midface loses volume and skin descends, so the fold is often a symptom rather than the problem. A dissolvable gel filler can soften it, but filling the fold directly without restoring cheek support can produce a heavy, shelf-like look. Support first, line second.
Key points
- The fold is often a symptom of midface volume loss.
- Restore cheek support first, then reassess the fold.
- Direct overfilling creates a shelf or distorts the smile.
- The area moves constantly, so results last about 6–12 months.
- The angular artery is nearby; occlusion is a recognised risk.
Why do the folds deepen?
With age, the fat compartments of the cheek shrink and descend, bone support subtly reduces, and skin loses elasticity. The fold is where the descended cheek tissue meets the relatively fixed area around the mouth. Smiling and speaking keep the crease active, which is why filler here breaks down faster than in quieter areas.
Fill the fold or the cheek?
| Direct fold filling | Indirect midface support | |
|---|---|---|
| Target | The crease itself | Cheek volume and support |
| Effect | Softens the line | Lifts tissue that presses into the fold |
| Risk | Shelf-like ridge, smile distortion | Overfilling the midface |
| Product | Small amounts of soft gel | Deeper, firmer gel |
| Typical plan | Small top-up after support | First step, then reassess |
Many patients benefit most from the indirect approach, sometimes with a small direct top-up. A face that looks natural at rest and in motion usually needs both cause and symptom considered together.
Who is it for?
Good candidates have moderate folds driven by volume loss, with reasonable skin quality. Very deep folds with significant skin laxity may respond better to a combination approach, or may need surgical consultation for honest expectations. Skin-tightening devices and collagen-stimulating injectables are sometimes discussed as part of a wider plan.
What is recovery like?
Injection takes minutes; swelling and possible bruising settle over several days. Because the area moves constantly when you speak and smile, the gel integrates gradually and the final result is judged at about two weeks. Avoid pressing or massaging the area unless instructed.
What can go wrong?
Temporary swelling, tenderness, and bruising are common. Overfilling directly can create a shelf-like ridge or distort the smile, which is why restraint matters. The nasolabial region lies near the angular artery, so vascular occlusion is a recognised risk: practitioners use careful technique and keep the dissolving enzyme and emergency protocols ready.
When is urgent review needed?
- Severe pain or whitening, duskiness, or net-like mottling near the nose or upper lip.
- Any visual symptom after treatment.
- The area becomes increasingly firm, red, or tender days later.

Frequently asked questions
Why do nasolabial folds keep coming back after filler?
The area moves constantly when you speak and smile, so filler here breaks down faster than in quieter areas, typically over six to twelve months. The fold is also often a symptom of midface volume loss rather than the problem itself.
Is it better to fill the fold directly or restore the cheek?
Many patients do best with the indirect approach: restoring midface support first, then reassessing the fold. Often it softens enough that only a small superficial refinement is needed, giving less product, better movement and a more natural result.
What can go wrong with fold treatment?
Overfilling directly can create a shelf-like ridge or distort the smile, which is why restraint matters. The nasolabial region also lies near the angular artery, so vascular occlusion is a recognised risk, and practitioners keep hyaluronidase and emergency protocols ready.
Risks & Limitations
- Vascular occlusion — a time-critical emergency in which filler blocks a blood vessel. It can cause skin loss and, rarely, blindness.
- Nodules, lumps or granuloma formation, which may need treatment or dissolution.
- Infection at the injection site.
- Asymmetry or over-correction; over-treatment is harder to correct than under-treatment.
- Migration of filler away from the intended area.
- Temporary brow or eyelid droop after botulinum toxin, which resolves as the effect wears off.
- Bruising and swelling. All injectable results are temporary and maintenance is required.
When to Seek Care
- Severe pain out of proportion to the procedure, or skin turning white, grey, mottled or dusky — this is a vascular emergency; seek care immediately.
- Any change in vision — seek emergency care immediately.
- Fever, spreading redness, warmth or pus at an injection site.
- A hard, painful lump that is growing.
- Drooping eyelid, difficulty swallowing, or difficulty breathing after botulinum toxin.
