HA vs CaHA Fillers: Choosing the Right One in SG
Introduction
In the world of modern aesthetics, dermal fillers have become one of the most popular treatments for rejuvenation, contouring, and restoring facial harmony — and Singapore is no exception. With busy lifestyles and the growing preference for non-surgical cosmetic procedures, fillers offer an ideal solution for achieving a refreshed and youthful look without downtime.
Among the many filler options available today, two stand out as the most widely used and clinically trusted: Hyaluronic Acid (HA) fillers and Calcium Hydroxyapatite (CaHA) fillers. Both deliver excellent results, but they work in different ways and are suited for different purposes.
So how do you decide between them?
This comprehensive 2025 guide breaks down the differences between HA vs CaHA fillers, including:
- What they are and how they work
- The advantages and disadvantages of each type
- Best treatment areas for both
- Results timeline and longevity
- Cost breakdown and maintenance
- Safety and aftercare tips
- How to choose the right filler for your aesthetic goals
Whether you’re new to fillers or considering switching products, this guide will help you make an informed choice that enhances your natural beauty — safely and effectively.
Understanding Dermal Fillers
Before comparing HA and CaHA fillers, it’s essential to understand what dermal fillers are and how they work.
Dermal fillers are injectable gels used to add volume, smooth wrinkles, and contour facial features. They help correct age-related volume loss, improve symmetry, and restore youthful firmness to the face.
They are non-surgical and minimally invasive, with immediate results and minimal downtime — making them an ideal option for people seeking natural rejuvenation.
At Dr Plus Clinic Singapore, dermal fillers are carefully selected and administered by qualified aesthetic doctors who specialise in safe, precise techniques tailored to each patient’s unique facial anatomy.
What Are Hyaluronic Acid (HA) Fillers?
Overview
Hyaluronic Acid (HA) is a naturally occurring sugar molecule found in the skin, eyes, and connective tissue. It helps maintain skin hydration, elasticity, and firmness by binding water molecules.
HA fillers are made from a synthetic form of hyaluronic acid, designed to mimic the body’s natural substance. When injected, they instantly add volume, smooth wrinkles, and hydrate the skin from within.
How HA Fillers Work
Once injected, HA fillers:
- Attract and retain moisture — keeping skin plump and hydrated.
- Fill hollow or sagging areas — restoring youthful contours.
- Smooth lines and wrinkles — by replenishing lost tissue support.
Common HA Filler Brands
Well-known examples include Juvederm, Restylane, and Belotero (brand names vary depending on clinic availability).
Duration of Results
Results typically last 6 to 18 months, depending on the product used, treatment area, and individual metabolism.
What Are Calcium Hydroxyapatite (CaHA) Fillers?
Overview
Calcium Hydroxyapatite (CaHA) fillers are made from microscopic calcium-based particles suspended in a smooth gel carrier. CaHA is a naturally occurring mineral found in human bones and teeth, making it biocompatible and safe for aesthetic use.
Unlike HA fillers, which mainly add volume and hydration, CaHA fillers also act as collagen stimulators, encouraging the body to produce its own collagen for long-term firmness and elasticity.
How CaHA Fillers Work
- Immediate lift and volume — the gel matrix adds instant support to the treated area.
- Collagen stimulation — the calcium microspheres trigger fibroblast activity, leading to gradual collagen regeneration over time.
- Long-term improvement — as the gel carrier dissolves, new collagen remains, maintaining firmness even after the filler fades.
Common CaHA Filler Brand
The most well-known CaHA filler is Radiesse (brand may vary by clinic).
Duration of Results
Results last around 12 to 18 months, sometimes up to 24 months depending on the area treated and patient’s skin condition.
Key Differences Between HA and CaHA Fillers
| Feature | Hyaluronic Acid (HA) | Calcium Hydroxyapatite (CaHA) |
|---|---|---|
| Main Ingredient | Hyaluronic acid (a sugar molecule) | Calcium microspheres in gel carrier |
| Primary Function | Add hydration and immediate volume | Lift, structure, and stimulate collagen |
| Results Onset | Immediate | Immediate with gradual improvement |
| Duration | 6–18 months | 12–24 months |
| Reversibility | Can be dissolved with hyaluronidase | Cannot be dissolved; must fade naturally |
| Texture | Softer and smoother | Thicker and more structural |
| Ideal Use | Fine lines, lips, under eyes, light contouring | Jawline, cheeks, temples, deeper folds |
| Collagen Stimulation | Minimal | Strong collagen-stimulating effect |
| Downtime | Minimal | Slightly longer due to viscosity |
| Cost (SGD) | $600 – $1,200 per syringe | $800 – $1,500 per syringe |
Both fillers are safe and effective, but their composition, purpose, and longevity differ — which is why professional assessment is crucial before treatment.
When to Choose HA Fillers
HA fillers are ideal for patients who want subtle, flexible, and reversible results.
Best Suited For:
- First-time filler users — due to reversibility and soft texture.
- Areas requiring precision — like lips, under eyes, and fine lines.
- Hydration-focused rejuvenation — ideal for those with dry or crepey skin.
- Facial balancing — gentle lift and contour without overdefinition.
Common Treatment Areas for HA Fillers:
- Tear troughs (under eyes)
- Lips and perioral area
- Nasolabial folds (smile lines)
- Cheeks and midface
- Chin enhancement
- Nose reshaping (non-surgical rhinoplasty)
Advantages of HA Fillers:
- Reversible with hyaluronidase (important for safety).
- Natural, soft results that integrate well with facial movement.
- Minimal downtime and excellent hydration benefits.
HA fillers are perfect for those seeking soft, hydrated, and youthful-looking skin with flexibility to adjust results later.
When to Choose CaHA Fillers
CaHA fillers are better for individuals who want stronger lift, structure, and collagen stimulation.
Best Suited For:
- Mature skin types — requiring firmness and deep rejuvenation.
- Facial sculpting and contouring — especially for mid-face and lower-face definition.
- Patients seeking long-term results — with collagen stimulation benefits.
Common Treatment Areas for CaHA Fillers:
- Jawline and chin contouring
- Cheeks and temples
- Nasolabial folds
- Lower face lifting
- Hand rejuvenation (to smooth wrinkles and restore volume)
Advantages of CaHA Fillers:
- Strong lifting power and long-lasting structure.
- Stimulates natural collagen and elastin production.
- Results continue improving for months even after treatment.
CaHA fillers are excellent for facial rejuvenation and contouring, offering a structural, firm result that builds over time.
Results Timeline: HA vs CaHA
| Time After Treatment | HA Filler Results | CaHA Filler Results |
|---|---|---|
| Immediately | Plump, hydrated, visible lift | Lift and firmness, slight tightness |
| 2–4 Weeks | Settled, natural softness | Collagen activation begins |
| 2–3 Months | Maintains volume | Firmer, tighter, smoother skin |
| 6–12 Months | Gradual fading | Results continue improving |
| 12–24 Months | Re-treatment needed | Lasting collagen support, then gradual fading |
Both offer impressive transformations, but CaHA fillers are known for their progressive rejuvenation due to collagen production.
Cost of HA and CaHA Fillers in Singapore
The cost varies depending on brand, doctor experience, and number of syringes used.
| Filler Type | Average Cost (SGD) | Longevity |
|---|---|---|
| Hyaluronic Acid (HA) | $600 – $1,200 per syringe | 6–18 months |
| Calcium Hydroxyapatite (CaHA) | $800 – $1,500 per syringe | 12–24 months |
Factors Affecting Price:
- Filler brand and quality
- Treatment area (smaller areas require less product)
- Clinic location and expertise of injector
- Complexity of treatment (e.g., multi-layer contouring vs fine line filling)
At Dr Plus Clinic Singapore, transparent pricing and ethical recommendations ensure that patients receive the best filler for their budget and aesthetic goals.
Combination Use: HA + CaHA for Optimal Results
Many patients benefit from combining HA and CaHA fillers to target multiple aesthetic concerns at once.
Why Combination Therapy Works
- HA adds hydration and softness to the skin.
- CaHA provides structure and long-term collagen support.
- Together, they create both instant and lasting rejuvenation.
Example Combination Plan:
- HA filler for under-eye or lip refinement.
- CaHA filler for cheek lift or jawline contour.
This synergy provides balanced, natural-looking rejuvenation — restoring youthfulness without altering facial expressions.
At Dr Plus Clinic Singapore, combination plans are customised after detailed facial assessment to ensure optimal results and natural proportions.
Safety Considerations
HA Fillers Safety
- Highly safe due to biocompatibility with human skin.
- Fully reversible with hyaluronidase, which dissolves HA instantly in case of overcorrection or rare complications.
CaHA Fillers Safety
- Safe when injected by trained professionals.
- Cannot be dissolved, so precision and expertise are crucial.
Both filler types require proper injection techniques to avoid side effects such as swelling, bruising, or unevenness.
At Dr Plus Clinic Singapore, all procedures are performed by qualified aesthetic doctors who prioritise safety, hygiene, and natural outcomes using medically approved products.
