CaHA Filler in Myeongdong, Seoul
Calcium hydroxylapatite (CaHA) filler does two jobs: it lifts and supports immediately, then prompts your skin to build its own collagen over the following months.
Quick answer
CaHA filler is made of tiny calcium hydroxylapatite microspheres in a gel. The gel gives immediate volume and lift; as it is absorbed, the microspheres stimulate collagen so support builds over months. It suits firm structural areas such as the jawline, chin, cheekbones and hands, usually 1.5–3 ml per session, and lasts about 12–18 months. Unlike hyaluronic acid filler, it cannot be dissolved with hyaluronidase, and it is not used in the lips or under the eyes.
How is CaHA different from HA filler?
Hyaluronic acid (HA) fillers add volume by holding water and can be dissolved if needed. CaHA is firmer, provides more lift per ml and adds a collagen-stimulating effect, similar in spirit to Juvelook. It is chosen when structure and longevity matter more than reversibility.
Who is it for?
- Jawline, chin and cheekbone contouring.
- Hand rejuvenation, see hand filler.
- Not for lips, under-eyes or areas where reversibility is important.
How Obliv plans CaHA filler
Your doctor decides whether CaHA or HA suits each area, then places CaHA deep on the bone for structure. Diluted CaHA can also be spread under thinner skin to improve firmness.
| Typical volume | Usually 1.5–3 ml per session |
|---|---|
| Technique | Deep on the bone; diluted for skin firmness |
| Pairs well with | Jawline filler, Thermage |
Results and recovery
Support is visible immediately; skin firmness continues to improve over the next few months.

Dermal fillers by area
Each area has different anatomy, depth and safety rules, so we plan it separately. Choose an area for a doctor-reviewed guide, or read the dermal fillers overview.
Lines caused by movement usually respond better to Botox by area; skin quality to skin boosters. Meet the doctors who plan every injection.

Frequently asked questions
Can CaHA filler be dissolved?
No, not with hyaluronidase. That is why we use it only in structural areas and plan placement carefully.
How long does CaHA filler last?
Usually 12–18 months, helped by the collagen it stimulates.
Can CaHA be used in the lips?
No. Lips and under-eyes need soft, reversible hyaluronic acid filler.
