1. What is Filler?
Filler treatments inject hyaluronic acid (HA) and other biocompatible materials beneath the skin to restore volume and soften wrinkles — a non-surgical option.
HA is a substance that naturally exists in the body, attracting moisture to provide skin elasticity and volume. As HA naturally decreases with age, replenishing it helps restore a youthful, healthy look.
Key Characteristics of Filler
Results are visible right after treatment.
HA is a safe material naturally absorbed by the body.
Hyaluronidase can dissolve the filler if needed.
2. Treatment Areas
Filler can be applied to many areas of the face to create natural volume and refined contours.
Nasolabial Folds
Naturally fills the deep folds running from the corner of the mouth to the nose, restoring a more youthful look.
Cheeks & Temples
Adds volume to flattened cheeks and temples for a fuller, healthier facial shape.
Lips
Adds natural volume to thin lips and defines the lip border more clearly.
Chin
Adds chin projection to refine the side-profile line for a more polished look.
Tear Trough
Fills hollows under the eye to improve a tired, shadowed appearance.
Nose Filler
Small adjustments to nasal tip or bridge improve nose shape without surgery.

4. Our Filler Principles
Natural Volume — Never Overdone
We restore volume so naturally that filler is not detectable — preserving the patient's original look. We aim for the result: "I can't tell what they did, but they look better."
Safe Injection Based on Anatomy
Major blood vessels and nerves run through the face in a complex pattern. Based on the precise anatomic knowledge of a board-certified plastic surgeon, we perform injection techniques that minimize vascular-injury risk.
Personalized to Facial Proportion
We analyze your facial proportions and balance holistically — not just filling wrinkles, but designing a tailored treatment that considers overall harmony.
5. Aftercare
Important guidelines for the best result
No Massage at the Treatment Site
Rubbing or pressing the treatment area before the filler settles can cause it to migrate. Do not touch the treatment area for at least 2 weeks.
Avoid Alcohol & Sauna on Day-of
Avoid alcohol, saunas, jjimjilbangs, and strenuous exercise on the day of treatment. Increased circulation can worsen swelling.
Results Last 6 Months to 1 Year
Depending on the product and treatment area, results last 6 months to 1 year. For sustained effect, maintenance treatments are recommended.
Notice: Mild swelling or bruising after treatment is normal and typically resolves naturally within 2–3 days.
