What are hyaluronic acid injections?
Hyaluronic acid is a sugar molecule that occurs naturally in the skin, where it binds water and keeps tissue plump and supple. Levels fall with age and sun exposure. In aesthetic medicine, HA is used in two main ways. Cross-linked HA forms a firmer gel used as a filler to add volume to the cheeks, lips, chin or under-eyes and to soften folds.
Non-cross-linked or lightly cross-linked HA is injected in tiny amounts across the face as a skin booster to improve hydration, fine lines and glow, as in our Water Glow injections. A major advantage of HA products is that they can be dissolved with hyaluronidase if needed.
Who is a good candidate?
- Volume loss in the cheeks, temples or under the eyes
- Smile lines, marionette lines or thin lips
- Dry, dull or dehydrated skin
- Fine lines and rough texture
- First-time patients who want a reversible option
HA injections should be postponed during pregnancy or breastfeeding, with active infection, acne flare or cold sores in the area, and around dental treatment. People with a history of filler complications or certain autoimmune conditions need a careful review first. The doctor will explain whether a filler, a booster or another treatment is the better fit.

HA filler or HA booster: what's the difference?
A filler is placed deeper and in specific spots to change shape and volume, with results visible immediately that often last around 6–18 months. A booster is spread in small droplets across a wider area to hydrate the skin rather than reshape it, usually as a course of sessions a few weeks apart with effects lasting a few months. Many people combine both. The doctor recommends the right product and amount at consultation, and results vary from person to person.
How the treatment works
-
Consultation
The doctor assesses your skin and face shape and decides whether a filler, booster or combination fits your goals.
-
Comfort
The skin is cleansed and numbing cream is applied.
-
Injection
HA is injected with a fine needle or cannula, either at precise points (filler) or across the area (booster).
-
Aftercare
Avoid makeup for the rest of the day, and skip saunas, alcohol and intense exercise for a day or two.
Tips for international patients
- Bring photos of the look you want, or explain your goals clearly at consultation.
- Allow a day or two before important photos for swelling or small bumps to settle.
- Ask about combining an HA booster with Botox in the same visit.

Frequently asked questions
How long do hyaluronic acid injections last?
HA fillers typically last around 6–18 months depending on the area and product. HA boosters usually last a few months and work well as a course.
Are hyaluronic acid injections safe?
HA is naturally found in the skin and the injections are widely used, but side effects such as swelling, bruising and rarely more serious complications can occur, so treatment should be done by a doctor.
Can hyaluronic acid filler be removed?
Yes. HA filler can be dissolved with hyaluronidase ( Hyalase) if needed.
Do HA injections hurt?
Numbing cream is used, and many fillers contain lidocaine, so most people feel only mild discomfort.
What is the difference between HA injections and Botox?
HA adds volume or hydration, while Botox relaxes muscles to soften expression lines. They are often used together.
How much do hyaluronic acid injections cost in Seoul?
The price depends on whether you need a filler or booster and how much, so the doctor confirms it at consultation. See the Water Glow injection price page for booster prices.
