Korean Wrinkle Fillers: Fine Lines Need a Different Filler From Deep Folds, and Some Wrinkles Need No Filler at All

I'm Dr. Hyunji Kim, director of Delphic Clinic in Gangnam, one minute from Sinnonhyeon Station. I trained through Korea University Medical Center and I am a member of the Korean Filler Society and the Korean Academy of Aesthetic Surgery & Laser Medicine, among others. Lifting, laser and anti-aging are the core of my practice, and much of my filler work is about lines rather than volume.

Korean wrinkle fillers come up in my consultation room several times a week, usually from patients who point at two very different things in the same breath: a fine line on the cheek and a deep fold beside the mouth. They expect one syringe to handle both. It rarely does, and sometimes neither line is a filler problem. This page explains how I tell them apart and what I use for each.

Etched line or deep fold: a pinch test in the mirror

My overview of Korean filler areas and products covers the face as a whole. For wrinkles specifically, start with this quick check. Gently stretch the skin on either side of the line with two fingers and watch what happens.

Thin gels for fine lines: the wrinkle-specific options

Fine lines sit in thin skin close to the surface. A firm gel placed there can look lumpy or catch the light, so I prefer options made for the job. Our menu lists Belotero 1cc as a wrinkle-specific filler, and Rejuviel 1cc in a wrinkle version made by the Rejuran maker.

With fine lines I use small amounts and spread them thinly, then review. If a line is part of generally thin, crepey skin, I often suggest a booster for skin quality alongside or instead of filler.

Structural support for nasolabial and marionette folds

Deeper folds beside the nose and mouth are a different job. Our Juvederm and Rejuviel options list the nasolabial folds and marionette lines among their areas, alongside the cheeks and chin. The point is not to fill the crease itself to the brim; it is to restore support so the crease softens.

I compared these two brands in my post on Korean filler brands and how to ask which one is in the syringe. For wrinkles, the brand matters less than matching the gel and depth to the line in front of me.

A wrinkle is a symptom. If I only fill the line without asking why it formed, I am treating the shadow and missing the cause.— Dr. Hyunji Kim, Delphic Clinic

Wrinkles a filler can't fix

• Lines that appear only when you smile, frown or raise your brows; filling them at rest does not stop the movement
• Folds caused mainly by sagging, where lifting the tissue does more than adding volume
• Crepey, sun-damaged skin covered in fine crinkles; skin quality treatments suit it better
• Lines in an area that has already been filled several times, where adding more risks a heavy look

That last point is common. Faces often drift into looking overfilled one wrinkle at a time, which I explain in my post on pillow face filler and how I avoid it.

For folds driven by sagging, the honest answer is often a lifting consultation rather than filler. I discuss when cheek support helps and when it does not in my post on filler in cheeks to lift jowls.

Who I would turn away from wrinkle filler this week

• Anyone with active infection, a cold sore or irritated skin in the area
• Patients expecting every line to vanish, which tends to lead to too much product
• Faces with old filler that has not been assessed first
• Travellers with an important event the next day, before swelling has had time to settle

Planning wrinkle filler around a short trip

1. 1

   Early in the trip

   Consult and, if suitable, treat in the first days, so swelling and any bruising can settle before you leave.

2. 2

   Keep it simple

   One or two priority lines on the first visit. More can be added later; removing too much is harder.

3. 3

   A short check

   If you can, see the result a few days later before deciding whether anything else is needed.

4. 4

   Know the exit

   Hyaluronic acid filler can be dissolved with hyaluronidase if needed, which is part of why I start conservatively.

If you are not sure whether your wrinkles need filler, a booster or a lifting approach, come in for a free one-to-one consultation. I will check each line and tell you honestly which ones filler can help and which it cannot. English and Chinese interpreters are on site, you pay the same price as a Korean patient, and we are one minute from Sinnonhyeon Station Exit 3.
