HArmonyCa
Hybrid HA + CaHA Injectable

£600–£800 18–24 months Minimal downtime

What is HArmonyCa?

HArmonyCa is a revolutionary hybrid injectable that combines two proven aesthetic ingredients in a single product: Hyaluronic Acid (HA) and Calcium Hydroxyapatite (CaHA). This unique combination delivers immediate lifting and volumising effects from the HA component, while the CaHA microspheres provide long-term collagen stimulation and structural support that develops over the following months.

HArmonyCa was developed by Allergan Aesthetics (the makers of Juvederm) and represents a significant innovation in aesthetic injectables — combining the immediate gratification of a traditional filler with the long-term bio-stimulating benefits previously only available from separate treatments like Sculptra or Radiesse.

Clinical note

HArmonyCa is specifically designed for deep injection into the cheeks and mid-face. The HA component provides immediate lift and volume, while the CaHA component stimulates collagen production over 3–6 months. The HA component can be partially dissolved with hyaluronidase if needed, though the CaHA component is not reversible.

What can be treated?

  • Cheek augmentation: Restoring volume and lifting the mid-face.
  • Jawline definition: Improving jawline contour and structural support.
  • Facial contouring: Overall facial reshaping and volumising.
  • Skin quality: The collagen-stimulating effect improves skin thickness and quality in the treated area.

What to expect — the process

  • The treatment: HArmonyCa is injected deep into the tissue using a cannula or needle. The treatment takes 30–45 minutes. Topical numbing cream is applied beforehand.
  • Immediate results: Volume and lift are visible immediately after treatment, though some swelling is normal for 24–72 hours.
  • Gradual improvement: The collagen-stimulating effect of the CaHA component develops over 3–6 months, providing additional improvement beyond the initial result.
  • Duration: Results typically last 18–24 months, longer than standard HA fillers due to the CaHA component.
Important safety information

HArmonyCa contains both HA and CaHA components. While the HA component can be partially dissolved with hyaluronidase, the CaHA component is not reversible. As with all injectable treatments, there is a risk of vascular occlusion. Ensure your practitioner carries hyaluronidase and has a clear protocol for managing vascular complications.
