HArmonyCa in Toronto

HArmonyCa is a hybrid injectable from Allergan Aesthetics, the company behind Botox and the Juvéderm filler range. It combines two materials in one syringe: cross-linked hyaluronic acid, which lifts and adds volume immediately the way a dermal filler does, and calcium hydroxylapatite microspheres, which stimulate your own collagen production over the following months. It was the first product to combine the two categories, and the Canadian version, HArmonyCa with Lidocaine, includes a local anaesthetic in the formulation for comfort. It's injected into the deep dermal and subdermal layers of the face, most often the cheeks, jawline, and pre-jowl area, by a trained medical professional.

HArmonyCa works through two mechanisms running on different clocks. The hyaluronic acid component is a cross-linked gel that holds water and lifts the tissue it's injected into, so there's a visible change on the day of treatment. The calcium hydroxylapatite component is made of microspheres 25 to 45 microns across that remain in the tissue and act as a scaffold, activating fibroblasts, the cells that produce collagen. Over the following months the skin builds new collagen around the microspheres. Studies measured increased tissue density and firmness at 60 to 90 days and confirmed increased collagen in treated areas at 180 days, which is why the result matures over time rather than peaking on day one.

A regular dermal filler is hyaluronic acid alone. It gives an immediate result, and when the gel breaks down the result goes with it. HArmonyCa keeps that immediate filler effect but adds calcium hydroxylapatite, a biostimulator that prompts your skin to produce new collagen of its own. So while the hyaluronic acid gradually softens, the new collagen is building, and that structural change belongs to your own tissue rather than to a product that gets cleared. In practice this makes HArmonyCa suit a different goal than a standard filler: it's less about placing precise volume in one spot and more about lifting and firming the mid and lower face as a whole. Allergan reports results lasting up to 18 months.

Allergan reports that HArmonyCa results last up to 18 months. The shape of the result changes across that time. The hyaluronic acid lift is strongest in the early weeks and gradually softens as the gel is broken down by the body. The collagen phase moves in the opposite direction: measurable increases in tissue density appear from around 60 to 90 days, with increased collagen confirmed in studies at 180 days, and that firmness carries the result through the later months. Because the collagen is your own tissue, the treated area doesn't simply snap back to its starting point when the product itself is gone. Whether and when a repeat treatment makes sense is reviewed at a follow-up consultation.

Yes. HArmonyCa with Lidocaine received Health Canada authorization, and Allergan Aesthetics launched it in Canada in May 2026 as the first dual-action collagen-stimulating injectable of its kind on the Canadian market. Before that, the product had already been in use internationally, with approvals in more than 30 countries since its original launch. In Canada it's a professional-use injectable, administered by trained medical professionals, and Allergan maintains a clinic locator for verified providers. As with any injectable, the product itself being authorized is only half the picture; the assessment, injection technique, and follow-up are what determine the result, which is why treatment starts with a consultation rather than a booking.

Downtime is minimal for most people. The common side effects are the ones familiar from any injectable: bruising, swelling, tenderness, and sometimes itching at the injection points, which typically settle over a few days. The product contains lidocaine, so the treatment itself stays comfortable. Standard aftercare advice is to avoid strenuous exercise for 24 hours and direct sun exposure for the first week. The immediate lift is visible straight away, though the treated area can look slightly fuller than the final early result while any swelling settles. The collagen phase that follows involves no downtime at all; the tissue changes happen gradually over the following months without anything visible on the surface.

HArmonyCa is priced per syringe, and the number of syringes depends on the areas being treated and the degree of change you're after. A treatment covering the cheeks, jawline, and pre-jowl area on both sides uses more product than a single-area treatment, so the honest answer to cost starts with an assessment rather than a flat number. As a newer premium injectable from Allergan, it sits at the higher end of the injectable range in most Toronto clinics. At Lucie Mé, the consultation is complimentary: the clinician confirms whether HArmonyCa is the right treatment, maps the syringe count for your plan, and gives you the exact cost before anything is booked.
