HarmonyCA is a next-generation injectable from Allergan that combines Hyaluronic Acid with Calcium Hydroxyapatite — a collagen-stimulating agent — in a single product. This dual-action formula provides immediate HA-based hydration and soft tissue support, while simultaneously triggering a progressive collagen-stimulation response in the dermis.
Unlike standard HA fillers, HarmonyCA is designed for broad facial rejuvenation — improving skin quality, firmness, and hydration across large areas rather than adding targeted volume. It is particularly suited to clients with general skin laxity, loss of radiance, and early structural loosening across the cheeks and jawline.
Immediate improvement in skin hydration and a subtle lifting effect, followed by progressive collagen stimulation over 4–8 weeks. The result is a refreshed, firmer-looking complexion — sitting between a biorevitaliser and a structural filler in its effect profile. Most clients maintain with a single treatment per year after an initial course of 1–2.
The REGEN Method
HarmonyCA's collagen-stimulation mechanism places it firmly within the Generate pillar — it works at a tissue level to improve the structural quality of skin over weeks following treatment. Unlike fillers that simply add volume, HarmonyCA triggers a biological repair response.

Both are broad-area injectable treatments that improve skin quality rather than adding targeted volume. HarmonyCA adds a collagen-stimulating Calcium Hydroxyapatite component that Profhilo does not have. The two products are complementary and can be sequenced — Dr Chris will advise on the most appropriate approach.
Minimal. Some mild redness and occasional bruising at injection sites may persist for 24–48 hours.
Most clients start with 1–2 treatments spaced 4–6 weeks apart. A single yearly maintenance treatment is then sufficient for most clients.
