Quick answer · What is Smile Line Fillers?
Smile line fillers are hyaluronic acid injections that soften the laugh lines around the mouth, mainly the nasolabial folds. A flexible gel is placed beneath the line so it softens at rest and still moves naturally when you smile. A session takes about 20–30 minutes, with mild swelling or bruising for a day or two, and results usually last 9–12 months.

How it works
Flexible gel that moves when you smile
Smile lines deepen as the cheeks lose volume and the skin loses elasticity. A flexible, medium-density hyaluronic acid gel is placed beneath the line, sometimes with support higher in the cheek, so the line softens without stiffness. This area has important blood vessels, so careful technique matters.
-
Assessment & numbing
Your doctor looks at the lines at rest and when you smile, then applies numbing cream.
-
Gentle injection
Filler is placed slowly in small amounts, often by cannula, to soften the line evenly.
-
Natural movement
Lines look softer straight away, and your smile stays natural as swelling settles.

FAQ
Smile Line Fillers questions we hear every day
Do smile line fillers hurt?
Most patients feel only pressure and brief stinging. Numbing cream and lidocaine in the filler keep it comfortable.
Will my smile look stiff?
Not with a flexible gel placed conservatively. Your doctor checks your expression during treatment.
How long do smile line fillers last?
Results typically last about 9–12 months, depending on the product and how deep the lines are.
Are there risks?
Bruising and swelling are common. A rare but serious risk is filler entering a blood vessel; careful technique reduces this, and hyaluronic acid filler can be dissolved with hyaluronidase if needed.
Smile line filler or botox?
Filler softens folds caused by volume loss, while smile line botox can help with lines driven by muscle movement. Your doctor will explain which suits you.
How much do smile line fillers cost in Myeongdong?
Price depends on the number of syringes needed. The same price list applies to every nationality and is given to you in writing before treatment. See our filler and botox price list.
