Smile Lines: When a Skin Booster Works Better Than Filler

October 19, 2026
Smile line treatment at YAAN Clinic Gangnam, Seoul

Quick answer: Fine, shallow smile lines often respond well to a skin booster that improves the skin around them. Deeper folds caused by volume loss usually need a filler, and folds caused by sagging cheeks may improve more with lifting. YAAN Clinic offers smile line filler, boosters and lifting after assessing the cause.

Filling a fold that is really caused by sagging can make the face look heavy. Identifying the cause first gives a more natural result.

What causes smile lines?

  • Skin thinning and fine creasing
  • Volume loss in the mid-face
  • Cheek descent with age
  • Expression and genetics

When a booster is the better choice

  • Lines are shallow or mainly visible when smiling
  • The skin around the mouth looks thin or dehydrated
  • You want subtle improvement without added volume

When filler or lifting helps more

A typical combined plan

Many patients start with a booster such as Hilo Wave or Skinvive to improve skin quality around the mouth, then reassess. If a fold is still visible at rest, a small amount of filler is added. When the fold is mainly caused by sagging cheeks, lifting comes first so less filler is needed.
