Direct answer: HArmonyCa contains cross-linked hyaluronic acid (HA) and calcium hydroxylapatite (CaHA) microspheres. Hyaluronidase acts on HA; it should not be presented as a way to completely remove the CaHA component or make the treatment fully reversible.
Medical review: Dr. Liu Wei-chung · Reviewed September 1, 2026
Two materials require a more careful conversation
The HA component provides early support, while the CaHA component has different material characteristics and tissue interactions. Before treatment, confirm the exact product, treatment area, planned layer, amount and what the clinic can do if the early appearance differs from expectations.
Do not judge the final result too early
Swelling, bruising, tenderness and temporary asymmetry may affect the early appearance. Do not massage, inject another product or seek unverified “dissolving” treatment on your own. Contact the treating clinic and document the product, date, area, symptoms and their progression.
When urgent assessment is needed
- Increasing or severe pain
- Blanching, mottling or an unusual colour change
- Visual symptoms, severe headache or neurological symptoms
- Rapidly worsening swelling, fever or signs of infection
What to prepare for a second opinion
- Product name, lot information if available and amount used
- Injection date, location and treatment plane if known
- Clear photographs taken in consistent lighting
- Current symptoms, medication and relevant medical history
Frequently asked questions
Can hyaluronidase remove HArmonyCa completely?
No. It may act on the HA component when medically indicated, but it is not a complete reversal method for CaHA.
Should I wait or seek help?
Routine swelling can be observed according to the clinic’s instructions, but any warning sign or rapid worsening requires prompt medical assessment.
