Nasolabial Fold (Smile Line) Fillers

What Are Nasolabial Folds and Why Do They Form?

Nasolabial folds are the natural grooves that run from the sides of the nose to the corners of the mouth. Over time, these lines can deepen as cheek volume descends with age or weight changes, creating visible creases and shadows around the lower face. Repeated facial expressions, sun exposure, and collagen loss can further etch these lines into the skin.

Treating the fold alone isn’t always the most effective approach. Often, adding subtle mid-face (cheek) support helps lift the tissue above the fold, softening it more naturally for balanced, long-lasting results.

How Smile Line Filler Treatment Works

Smile line (nasolabial fold) fillers use hyaluronic acid (HA) – a molecule naturally found in the skin – to restore gentle support and volume beneath the folds that run from the nose to the mouth. By replenishing structure in and around the crease, the treatment reduces depth and shadowing, giving the lower face a smoother, fresher appearance while maintaining your natural expression.

During your appointment, your clinician will place small, precise injections using a needle or micro-cannula, chosen according to your facial anatomy and comfort. In some cases, subtle mid-face (cheek) support may be added to enhance lift and balance. The procedure typically takes 15-30 minutes with minimal discomfort and no downtime; most patients return to normal activities the same day.

Who This Treatment Is For

• You’ve noticed deepening smile lines or persistent lower-face shadowing even at rest
• You want a non-surgical, subtle refresh with little to no recovery time
• You prefer a natural, proportion-led result that keeps your expression soft and genuine

Results are visible immediately and continue to refine over the following 10-14 days as the filler integrates with the skin. On average, results last 9-12 months depending on the product used, placement, and individual metabolism.

What to Expect and Aftercare

Your smile line filler treatment begins with a detailed consultation at Omniya Clinic in Knightsbridge, where your clinician will review your facial anatomy, medical history, and goals. Once a personalised plan is created, small amounts of hyaluronic acid filler are precisely injected into the nasolabial folds using either a fine needle or micro-cannula for accuracy and comfort. Most treatments take 15-30 minutes and are well tolerated.

Aftercare

• You can return to normal activities the same day.
• Avoid makeup for 24 hours and strenuous exercise, alcohol, or saunas for 48 hours.
• Mild swelling or bruising may appear and typically settles within a few days.
• Sleep on your back if possible and avoid pressure on treated areas.
• The most natural finish appears after 10–14 days once the filler has fully settled.

Results are visible immediately, though the area may look slightly fuller at first due to mild swelling. With time, the filler integrates seamlessly into the skin, creating a smooth, refreshed appearance that typically lasts 9-12 months. Maintenance sessions can be scheduled to preserve your results over time.
