The basics

What is smile line filler?

Smile lines deepen as the mid-face loses volume and the cheeks descend. They can make the face look tired even when skin quality is good.

We restore support beneath the line and, where needed, in the cheek above it, so the crease softens while your smile stays natural.

Who is a good candidate?

  • Noticeable smile lines or deep folds
  • Mid-face volume loss with aging
  • A tired look despite good skincare
  • Natural, youthful refresh without surgery

Your visit

How the treatment works

Consultation

Your doctor assesses your smile lines and mid-face volume, facial balance and goals in English, and agrees a plan with you.

Numbing

Topical anesthetic is applied for comfort; most HA fillers also contain lidocaine.

Injection

Small, precise amounts are placed with a fine needle or cannula — about 20–30 minutes.

Check and aftercare

We review the result with you in the mirror and give written aftercare. A follow-up check is recommended.

Aftercare and recovery

  • Mild swelling or bruising usually settles within a few days
  • Avoid heavy exercise, alcohol and saunas for 24–48 hours
  • Do not press or massage the treated area unless your doctor advises it
  • A follow-up check helps fine-tune the result

How to choose the right clinic

  • Doctors who specialize in injectables perform your treatment
  • Certified, traceable products and sterile technique

FAQ

Smile Line Filler questions, answered

Are smile lines and nasolabial folds the same?

Yes — "smile lines" is the everyday name for nasolabial folds.

How long does smile line filler last?

Usually 9–12 months.

Will my smile look stiff?

No. We place filler to support the area, not to block movement.

Is cheek filler needed too?

Sometimes. Lifting the cheek reduces the fold and often gives a more natural result.

How much does smile line filler cost at Nest Clinic?

Cost depends on the product and amount needed. See our filler price list or message us on WhatsApp for a personal quote.
