Expression check
The doctor watches you frown, smile and raise your brows to map which muscles create each line.
A forehead line and a smile line are caused by different things, so they rarely share the same best treatment. Use our area-by-area table to see what suits each wrinkle, then learn how combining options and planned top-ups keep results steady.

Wrinkles are best treated according to where they are and what causes them. Expression lines on the forehead, frown area and around the eyes usually respond best to wrinkle-relaxing injections; smile and marionette lines linked to volume loss often suit filler; and crepey or neck lines benefit from skin-quality care. In Gangnam, Seoul our doctors frequently combine two approaches for a smoother, natural result.
The best option changes with location, because some areas crease from muscle movement while others fold from volume loss or thinning skin.
| Area | Usual cause | Best first option | Helpful add-on |
|---|---|---|---|
| Forehead | Lifting the brows | Wrinkle-relaxing injection | Skin booster for etched lines |
| Frown lines (glabella) | Frowning muscles | Wrinkle-relaxing injection | Fine filler if deeply etched |
| Around the eyes | Smiling, thin skin | Wrinkle-relaxing injection | Rejuran Eye for crepey skin |
| Smile lines (nasolabial) | Mid-face volume loss | Filler or volume support | Lifting device for laxity |
| Mouth corners and chin | Muscle pull, volume loss | Injection plus filler | Collagen-supporting booster |
| Neck | Thin skin, repeated bending | Neck wrinkle filler | Lifting for loose skin |

A dynamic wrinkle appears only when you make an expression; a static wrinkle stays visible when your face is relaxed. Look in a mirror with a neutral face, then raise your brows or smile.
Visible only with expression. Wrinkle-relaxing injections that reduce excess muscle activity are usually the most effective option.
Present at rest because the skin has creased over years. They often need filler, boosters or collagen support in addition to injections.
Deeper grooves such as smile lines are usually driven by volume loss and sagging, not just skin creasing.
Combining treatments often gives a softer, more balanced result because each one handles a different cause, so no single product has to be overused. Relaxing a muscle while improving the skin above it, for example, can reduce how hard each step needs to work.

Wrinkle results last longest with regular, lighter top-ups rather than waiting until lines fully return. Wrinkle-relaxing injections are listed by the clinic at around 3 to 6 months, while filler and skin boosters follow their own schedules.

Suitability is a medical decision made by your doctor after an in-person consultation and review of your health history.
The doctor watches you frown, smile and raise your brows to map which muscles create each line.
Each zone is matched to an option, and you agree on the areas and the degree of softening you prefer.
Wrinkle-relaxing injections take about 5 minutes; filler areas are numbed first.
Effects of relaxing injections develop over several days, so a short check before you fly can be arranged if possible.
You leave with written aftercare and a maintenance schedule that fits your future visits to Korea.

Most wrinkle injections are listed with same-day recovery, so they fit easily into a city break. Relaxing injections take several days to show their effect, so treatment on day one or two of your stay lets you see early changes before flying home. Avoid lying flat, heavy exercise and saunas for the rest of the treatment day. Many patients align top-ups with return trips, and the clinic offers a free 3-month follow-up after you leave.

Lines caused by repeated muscle movement respond best, such as forehead lines, frown lines and crow's feet. The clinic also lists the nose bridge, mouth corners and chin for wrinkle-relaxing injections. Lines from volume loss usually need another approach.
That is the aim. Doses and injection points are planned around your own muscle movement so you keep natural expression. Our doctors prefer softening lines rather than freezing the face, and they adjust the plan to your preferences.
Usually not. Smile lines are mainly caused by mid-face volume loss and laxity, so relaxing injections rarely help them. Filler, collagen stimulation or lifting are more often used, sometimes together.
Most people notice softening within a few days, with the full effect usually after about two weeks. Results vary, and the clinic lists a typical maintenance period of around 3 to 6 months before a top-up.
Treating expression lines before they become deeply etched may make them easier to manage. Early care is often lighter, but the decision depends on your skin and goals, and the doctor will not recommend treatment you do not need.
