Smile line filler softens nasolabial folds, the lines that run from the nose to the corners of the mouth, for a smoother, more rested look. At Cosmetica Med Spa in Boca Raton, we plan every treatment to keep your smile natural and expressive.

What smile line filler treats

  • Nasolabial folds
  • Marionette lines at the corners of the mouth
  • Deep creases around the lower face

How it works

A flexible hyaluronic acid filler is placed beneath the fold to lift and smooth it. Because smile lines are often linked to cheek volume loss, your injector looks at the whole mid-face.

What to expect at your appointment

Treatment takes about 30 minutes. You may have mild swelling or bruising for a few days.

Results

Lines look softer right away, with final results in about two weeks. Individual results vary.

Smile line filler cost in Boca Raton

Smile line filler starts at $699 per syringe.

Frequently asked questions

How long does smile line filler last?

Results usually last 6 to 12 months, depending on the filler and how expressive your face is.

Is it better to treat the cheeks instead?

Sometimes. Smile lines often deepen because the cheeks lose volume. Your injector may recommend cheek filler to lift the area, alongside or instead of filling the lines directly.

Will it look natural when I smile?

Yes, when the right filler and amount are used. Softer, flexible fillers move with your expressions.
