Why HArmonyCa Results Keep Getting Better: The Science Explained
Most injectable treatments are straightforward: you put product in, you get a result, the product breaks down, the result fades. HArmonyCa does not follow this script. Patients report improvements weeks after their treatment and the science explains exactly why. Here’s what’s happening inside the skin when HArmonyCa is injected, and why it represents a meaningful scientific advancement in injectable aesthetics.
Understanding the Two Active Ingredients
Hyaluronic Acid (HA): The Immediate Architect
Hyaluronic acid is a substance that occurs naturally in the body and is well-established as one of the most effective volumizing agents in aesthetic medicine. In HArmonyCa, the HA is cross-linked, meaning the individual HA molecules are chemically bonded together to create a more stable, durable gel. This cross-linking makes the HA more resistant to breakdown, extending its volumizing effect and allowing it to integrate into the deep dermis and subdermal layers with structural integrity.
When injected, the HA gel spreads between the collagen fibres of the lower dermis, creating an immediate lifting effect. This is the result patients see on the day of treatment: restored contour, reduced sagging, and a refreshed appearance. If you’re curious about how HA behaves in other dermal filler treatments, that foundation is worth understanding.
Calcium Hydroxyapatite (CaHA): The Long-Game Builder
Calcium hydroxyapatite is a mineral compound that occurs naturally in human bone. In injectable aesthetic medicine, it has a long track record as a biostimulator: a substance that, when introduced into the dermis, triggers the body’s own repair mechanisms.
The CaHA in HArmonyCa is formulated as microspheres, tiny particles ranging from 25 to 45 microns in diameter. When deposited in the deep dermis, these microspheres do two things simultaneously. First, they form a physical scaffold that provides temporary structural support while the collagen-building process gets underway. Second — and more importantly for long-term results — they activate fibroblast receptors on the cells responsible for producing collagen and elastin.
Fibroblasts are the skin’s collagen factories. As we age, their activity declines, collagen production slows, and the structural framework of the dermis begins to deteriorate. CaHA essentially restarts the process, stimulating fibroblast proliferation and inducing the production of new collagen fibres, along with the remodelling of the extracellular matrix that supports them.
This process begins within approximately one week of treatment. By the four to eight week mark, the collagen-building effect becomes clearly visible: Skin is firmer, denser, and more elastically resilient. The improvements continue to accumulate over several months.
Why Combining HA and CaHA in One Syringe Matters
Clinicians have long known that combining HA fillers with biostimulators produces exceptional results. The two ingredients complement each other: HA provides immediate volumizing support while CaHA works on longer-term structural improvement. But combining them has historically meant separate products, separate appointments, and potential technical inconsistencies.
HArmonyCa — developed by Allergan Aesthetics — solves this by engineering both ingredients into a single, ready-to-use syringe. The formulation is optimised so that the cross-linked HA and CaHA microspheres work without interfering with each other. The high viscosity of the HA gel actually helps create a smoother, more precise injection, while the CaHA begins its scaffold-building and collagen-stimulating work in parallel.
The result is more than the sum of its parts: patients get immediate results that transition seamlessly into sustained structural improvement without the complexity or inconvenience of a multi-product protocol.
This dual-action principle is also what separates HArmonyCa from standard approaches — and it’s why we view it as a meaningful addition to our full injectable offering at Lucere.
What Clinical Research Shows
HArmonyCa’s performance is not speculative. Published clinical data — including an Italian real-life retrospective study published in the Journal of Cosmetic Dermatology — report that over 90% of patients showed clinically significant improvement in treated facial areas. The study also confirmed that HArmonyCa was compatible with other cosmetic procedures, including laser treatments and additional injectable treatments, with no adverse interactions reported.
Importantly, the CaHA microspheres were shown to stimulate fibroblast activity beginning within one week of injection, with new collagen formation detectable shortly thereafter. At nine-month follow-up, patients maintained significant improvement in skin firmness and facial structure compared to baseline.
The Role of Lidocaine
HArmonyCa also contains lidocaine — a local anaesthetic — at a concentration of 3 mg/ml. This is not incidental. Many injectable treatments require topical anaesthetic or additional lidocaine to manage patient comfort. By incorporating it directly into the formulation, HArmonyCa ensures that the treatment experience is consistently comfortable without relying on add-on numbing protocols.
The Injection Technique: Why It Matters for Results
HArmonyCa is injected into the deep dermis and subdermal layers using a retrograde linear fanning technique, typically via cannula. The technique allows the product to be distributed homogeneously across the target area, ensuring even collagen stimulation and avoiding surface irregularities.
Because the CaHA component is not reversible, placement precision is non-negotiable. Too superficial, and the product can create visible irregularities or nodules. Placed correctly — in the hands of an injector with a deep understanding of facial anatomy — the product integrates invisibly and performs exactly as designed.
This is why the injector matters as much as the product itself. At Lucere, Dr. Zaki Taher brings a level of anatomical knowledge and technical mastery that is genuinely uncommon. His training in MD Codes master injection techniques — one of only seven physicians in Canada selected for this credential — reflects a standard of precision that HArmonyCa rewards.
Frequently Asked Questions: The Science
How long does new collagen production last after HArmonyCa?
The CaHA microspheres gradually absorb into the body over time. However, the collagen they stimulate is real, endogenous collagen — your own skin’s structural tissue — which persists beyond the absorption of the CaHA itself. This is why results outlast the product’s physical presence: the structural improvement becomes self-sustaining to a meaningful degree.
Is calcium hydroxyapatite safe in the face?
Yes. CaHA has been used in injectable aesthetic medicine for over two decades and has an extensive safety record. It is biocompatible and gradually metabolised by the body. In HArmonyCa, the formulation has been specifically engineered for safe injection into the deep dermis and subdermal layers of the mid and lower face.
Can I feel the product after it’s injected?
Immediately following treatment, some firmness or slight fullness in the treated area is normal as the product settles. Most patients report that this resolves within a few days as the initial swelling subsides and the product integrates into the tissue. The end result should feel entirely natural.
How does HArmonyCa compare to traditional dermal fillers?
Traditional dermal fillers — like standalone HA products — provide volume and lift but do not actively stimulate your skin’s collagen infrastructure. HArmonyCa does both. The HA component delivers the immediate lift you’d expect from a filler; the CaHA component sets off a collagen-building process that continues to improve skin quality for months after treatment.
