HArmonyCa®
Why HArmonyCa®?
HArmonyCa® is an innovative dual-action injectable treatment that combines the immediate benefits of hyaluronic acid (HA) with the longer-term collagen-stimulating benefits of calcium hydroxyapatite (CaHA).
This unique combination works in two ways: the hyaluronic acid provides an immediate lifting and volumising effect, while the calcium hydroxyapatite helps stimulate your body’s own collagen production over time.
The result is a natural-looking improvement in facial contours, firmness and skin quality, both now and in the months following treatment.

What is HArmonyCa®?
HArmonyCa® is a hybrid injectable that combines two well-established ingredients in one treatment:
- Hyaluronic Acid (HA) – provides immediate volume, hydration and a lifting effect.
- Calcium Hydroxyapatite (CaHA) – supports your body’s natural production of collagen, helping improve skin firmness and structure over time.
This makes HArmonyCa® different from traditional hyaluronic acid dermal fillers. Rather than focusing solely on replacing lost volume, it also works progressively to improve the underlying quality and firmness of the skin.
How does HArmonyCa® work?
As we age, our natural production of collagen gradually decreases. This contributes to thinner, less elastic skin, loss of facial support and the development of sagging or laxity.
HArmonyCa® takes a dual approach to these changes.
The HA component provides an immediate lifting and volumising effect following treatment. The CaHA microspheres then work within the tissue to support your body’s own collagen production.
This means you can see an improvement straight away, while your skin continues to benefit from collagen stimulation over the following weeks and months.
What can HArmonyCa® help with?
HArmonyCa® may be a great option if you are looking to:
- Improve facial firmness and support
- Lift and redefine facial contours
- Improve mild to moderate skin laxity
- Restore some age-related volume loss
- Improve skin structure and quality
- Stimulate your own natural collagen production
- Achieve a refreshed, natural-looking result without surgery
Where can HArmonyCa® be used?
HArmonyCa® is most commonly used in the mid to lower face, including the cheeks and jawline, particularly in areas where skin laxity is beginning to develop.
Treatment areas will depend on your individual facial anatomy and concerns, and I will assess this carefully during your consultation before recommending where HArmonyCa® may give you the best result.
How is HArmonyCa® different from dermal filler?
Traditional hyaluronic acid dermal fillers are primarily used to restore volume, enhance facial features and improve contours.
HArmonyCa® goes a step further by combining hyaluronic acid with calcium hydroxyapatite.
The HA provides an immediate lifting and volumising effect, while the CaHA supports your body’s own collagen production. This gives HArmonyCa® both an immediate and progressive effect, improving facial support while also helping the skin become firmer over time.
How is HArmonyCa® different from other collagen-stimulating treatments?
There are now several excellent injectable treatments designed to improve skin quality and stimulate collagen, and they each work slightly differently.
What makes HArmonyCa® particularly exciting is its dual-action formulation. Rather than providing collagen stimulation alone, it combines CaHA with hyaluronic acid, so you receive an immediate lifting effect alongside the longer-term benefits of collagen stimulation.
When will I see results?
One of the benefits of HArmonyCa® is that you can see an improvement immediately after treatment due to the hyaluronic acid component. However, the treatment doesn’t stop working there.
The CaHA component supports new collagen production, meaning improvements in firmness and skin quality develop progressively over the following weeks and months.
How long does HArmonyCa® last?
Results vary between individuals, but HArmonyCa® results typically last between 12 and 18 months.
How the Timeline Works:
- Immediate (0 to 1 week): The hyaluronic acid (HA) component provides an immediate lifting and volumizing effect.
- 1 to 3 months: Calcium hydroxyapatite (CaHA) microspheres begin stimulating your body’s natural collagen production.
- 3 to 6 months: Collagen production peaks, improving skin firmness and structure as the results fully develop.
- 12 to 18+ months: The initial HA gradually breaks down, but the new collagen network continues to support the skin before slowly remodeling.
How many HArmonyCa® treatments will I need?
For many people, a single treatment may provide a noticeable improvement, with your results continuing to develop as new collagen is produced.
Your treatment plan will depend on your facial structure, skin condition and the degree of correction you are looking for.
What is the downtime?
As with other facial injectable treatments, you may experience some temporary redness, swelling, tenderness or bruising around the injection sites.
These effects are generally temporary, although everyone responds differently to injectable treatments.
Are there risks related to HArmonyCa®?
As with all injectable treatments, there are possible side effects (bruising, swelling, redness, itching or small lumps at injection sites). Serious complications are rare but will be discussed during your consultation so you can make a confident and informed decision.
