Sagging cheeks, prominent jowls, deepening nasolabial folds, and a blurred, lax jawline… these are the most common signs of aging. What is HArmonyCa™? How is it different from regular hyaluronic acid and collagen stimulators? Which concerns is it suitable for? How long does it take for the effects to appear, and how long do they last? Will there be swelling after injection, and are there any risks? This article provides a clear, comprehensive overview.
HArmonyCa™ combines two ingredients: cross-linked hyaluronic acid (HA) and calcium hydroxyapatite (CaHA) microspheres. These are mixed together through the manufacturer's proprietary DART™ technology. The hyaluronic acid provides immediate support and lifting, while CaHA continuously stimulates the body's own collagen regeneration, helping the skin gradually rebuild its firm structure from within. The actual suitability, injection sites, and dosage still need to be determined by a qualified physician based on facial shape, skin laxity, and the approved instructions for use. This article provides educational information for reference only and does not constitute a commitment to treatment.
What is HArmonyCa™?
HArmonyCa™ was developed by Allergan Aesthetics (now part of AbbVie), a global leader in medical aesthetics. Its official approved name in Taiwan is "HArmonyCa™ Dermal Filler (with Lidocaine)," with license number Taiwan medical device import license No. 038192. It also holds CE certification from the European Union.
It is not merely a hyaluronic acid filler, nor just a collagen stimulator. It is a composite injectable filler that combines HA and CaHA in a single formulation using patented technology, and it contains 0.3% lidocaine to enhance patient comfort during the procedure. This product is only available for administration by qualified physicians at our clinic; it is not sold as an individual syringe or provided for self-injection.
Why do many people consider HArmonyCa™? 3 Key Features at a Glance
This dual-action design is particularly suitable for those who want to improve facial laxity and lack of support, but also desire a natural look and do not wish to be "overfilled."
Dual-Action Principle: How do Hyaluronic Acid + CaHA work together?
As we age, the skin gradually loses collagen and hyaluronic acid, and fibroblast activity decreases. The face thus loses its original fullness and support, leading to fine lines, sagging, and a drooping contour. The dual-action combination of HArmonyCa™ addresses these issues along two timelines: "immediate" and "progressive":
| Component | Primary Action | Timeline |
|---|---|---|
| Hyaluronic Acid (HA) | Replenishes lost support and volume in the subdermal layer, instantly lifting the skin. | Immediately after treatment |
| CaHA Microspheres | Stimulates the proliferation of collagen fibers, remodeling the skin's internal structure. | Gradually appears over several weeks to months |
With this combination, a dense and refined collagen structure gradually forms within the skin, providing a longer-lasting feeling of firmness, rather than simply adding volume with a filler.
Who is HArmonyCa™ suitable for?
If you are experiencing the following conditions, you can discuss with your doctor during an aesthetic consultation whether HArmonyCa™ is suitable for you:
Common assessment areas for injection include the mid-face, lower face, and lateral face. The actual areas and dosage will be individually planned by the physician based on each person's facial condition, degree of laxity, and desired results.
How is HArmonyCa™ different from regular hyaluronic acid and collagen stimulators?
Typical hyaluronic acid fillers mainly focus on "immediate filling and support," while collagen stimulators primarily focus on "stimulating the body's own collagen regeneration," usually requiring multiple treatments to see gradual effects. HArmonyCa™'s unique feature is that it combines both mechanisms: HA provides immediate support and lift, while CaHA is responsible for stimulating subsequent collagen regeneration, allowing a single treatment to address both immediate and long-term improvement.
In short, HArmonyCa™ is not just about "filling"; it's more like helping the skin reactivate its self-repair capabilities, making the contours appear natural, firm, and vibrant.
Clinical Data and Dual Certification

The above data is from post-market clinical observations and research reports by the original manufacturer. Actual individual results and duration may vary depending on age, skin condition, area, dosage, metabolism, and lifestyle, and cannot be guaranteed.
Will the treatment be painful? What should I be aware of post-treatment?
HArmonyCa™ itself contains 0.3% lidocaine. Combined with topical anesthesia and cold compresses arranged by the doctor as needed, most people only experience mild stinging and find it quite tolerable.
Common temporary post-treatment reactions include erythema, edema, pain, tenderness, and itching, which usually subside within 24–48 hours. Swelling typically resolves within 1 week, and most people can resume normal activities. Within 24 hours post-treatment, it is recommended to observe the following:
- Use an ice pack or cold compress to alleviate swelling.
- Avoid strenuous exercise and makeup (recommended for 12 hours).
- Avoid exposure to direct sunlight, tanning beds, or extreme temperatures.
- If nodules appear, massage the treated area as directed by your doctor.
- If any abnormal or persistent adverse reactions occur, consult the treating physician as soon as possible.
Who is not suitable for HArmonyCa™?
In the following situations, it is recommended to discuss with your doctor whether other more suitable options are available:
- Known allergies to product components or steroids.
- Suffering from skin diseases, prone to keloids or hypertrophic scars.
- Infection or inflammation (acute or chronic) at the injection site or adjacent areas.
- Chronic bleeding or slow tissue healing due to illness or medication.
- Pregnant or breastfeeding.
- Under 18 years old.
HArmonyCa™ Frequently Asked Questions (FAQ)
How long does it take to see results from HArmonyCa™?
The support and lifting sensation provided by hyaluronic acid can usually be felt immediately after the treatment. The firming changes related to CaHA and collagen regeneration are more gradual, generally appearing progressively over several weeks to months. The swelling immediately after injection does not represent the final result; it is recommended to assess the actual outcome after the swelling subsides (approximately 1–2 weeks).
How long do the effects of HArmonyCa™ last?
According to the manufacturer's educational materials, the effects can last up to approximately 12–18 months. The actual duration may vary depending on age, skin condition, injection site, dosage, metabolism rate, and lifestyle, and cannot be guaranteed to be the same for everyone.
Can HArmonyCa™, hyaluronic acid, and Ultherapy/Thermage be combined?
Some people may combine different treatments based on their needs, either by area or in stages. However, the sequence, interval, and area arrangement of treatments all affect safety and outcome. It is recommended to have a physician unify the planning based on your treatment history, tissue condition, and treatment goals, rather than self-combining them.
Will HArmonyCa™ make my face look "plastic" or unnatural?
HArmonyCa™'s design philosophy is "instant lift, progressive firming," which rebuilds structure by guiding the body's own collagen regeneration, rather than simply stacking volume. Whether the result is natural depends critically on the dosage planning and the physician's injection technique and experience. It is recommended to choose a qualified physician who is familiar with facial anatomy and has extensive experience, and to fully communicate your desired personal features before treatment.
What are the side effects and risks of HArmonyCa™?
In addition to common temporary reactions like redness, swelling, pain, tenderness, and itching, rare cases may include nodules, infection, inflammation, allergic reactions, product displacement, or asymmetry. All injectable fillers carry a rare but serious risk of vascular occlusion. Therefore, it is crucial to choose a qualified physician who is familiar with facial anatomy and capable of managing complications for the procedure.
The above is general educational information and cannot replace a physician's professional diagnosis and assessment. Whether the treatment is suitable, its expected effects, and potential risks still need to be individually determined by a physician after a face-to-face consultation.
