Quick answer
What are smile line fillers?
Smile line fillers use a soft, flexible hyaluronic acid filler to soften laugh lines — the creases that frame the mouth and deepen when you smile. A flexible gel is chosen so the area still moves naturally with every expression.
Smile lines overlap with nasolabial folds, but the focus here is on finer, expression-driven creases rather than deep structural folds. For deep folds caused by volume loss, see nasolabial fold fillers.
