Natural-Looking Volume with Built-In Collagen Boost
HarmonyCa is a next-generation treatment designed to lift and support facial structure while encouraging long-term skin regeneration.
We assess your facial structure, ageing concerns, and suitability for a collagen-stimulating approach.
Topical anaesthetic is applied to ensure a comfortable experience before injection.
HarmonyCa is injected into targeted areas — usually the cheeks or jawline — using advanced techniques to sculpt and restore facial volume.
The calcium microspheres begin to stimulate collagen production, improving skin quality and firmness over time while the HA offers instant results.
It offers both instant volume (from hyaluronic acid) and long-term firmness (from calcium hydroxyapatite), delivering a dual-action result.
You’ll notice immediate improvement in volume and lift, with gradual skin tightening and collagen regeneration over several weeks.
Yes. It is FDA-approved and CE-marked, with a strong safety profile and natural bio-compatibility.
Results typically last up to 18 months, making it longer-lasting than many HA fillers.
