Quick Answer: What Are Calcium Hydroxylapatite Fillers?


Calcium hydroxylapatite (CaHA) fillers are biocompatible injectable dermal fillers composed of microscopic CaHA particles suspended in a gel carrier. Derived from a mineral naturally present in human bones and teeth, CaHA is widely used in aesthetic medicine for facial volumization, contour enhancement, and wrinkle correction.


Once injected, the gel component delivers immediate lifting and shaping, while the solid CaHA microspheres provide a stable scaffold that stimulates fibroblast activity and new collagen formation. This dual-action mechanism distinguishes CaHA fillers from purely volumizing options, allowing them to deliver natural-looking, longer-lasting results that continue to improve skin firmness and structural support over time.

Clinical Uses and Treatment Longevity


CaHA filler is commonly selected for areas requiring structural support, definition, and gradual skin quality improvement.


Common Indications

Midface and cheek augmentation

Jawline and chin contouring

Nasolabial fold correction

Temple hollowing

Hand rejuvenation


How Long Do CaHA Fillers Last?

Clinical outcomes from CaHA fillers often persist for 18 to 24 months, with some patients experiencing visible benefits beyond two years. Longevity depends on injection depth, treatment area, patient metabolism, and practitioner technique.


Safety Profile and Considerations


Calcium hydroxylapatite fillers have a strong safety record when administered by trained medical professionals. Because CaHA is non-animal and biocompatible, the risk of hypersensitivity reactions is low.


Common Reactions

· Mild swelling or bruising

· Temporary redness at injection sites


Important Contraindications

CaHA fillers are generally not recommended for superficial injections, areas with very thin skin, or patients with active infections, autoimmune disorders affecting connective tissue, or known hypersensitivity to filler components.


CaHA vs Hyaluronic Acid and PLLA: Key Differences Explained


Understanding how CaHA compares with other injectable fillers helps both patients and practitioners select the most appropriate treatment approach.


Calcium hydroxylapatite fillers provide a balance between immediate volumization and long-term collagen stimulation. Hyaluronic acid fillers primarily act as space-occupying gels that attract water for instant volume but do not actively stimulate collagen. Poly-L-lactic acid (PLLA) fillers, on the other hand, rely almost entirely on gradual collagen induction, with minimal immediate correction.


Because of this, CaHA fillers are often chosen when both instant contouring and sustained tissue remodeling are desired within a single treatment plan.

Product to Consider: CHArmacy® CaHA Filler


For clinicians exploring CaHA-based options, CHArmacy® caha filler is formulated to combine immediate aesthetic correction with long-term collagen stimulation. Its formulation integrates calcium hydroxylapatite microspheres with a viscoelastic gel system to support both short- and long-term outcomes.


what fillers are calcium hydroxylapatite


CHArmacy® incorporates precisely engineered CaHA microspheres produced using advanced manufacturing technology, enabling stable tissue support and controlled biodegradation. The inclusion of a high-viscoelasticity gel component allows for immediate wrinkle filling and contour refinement, while the CaHA microspheres gradually promote collagen formation around the treated area.


This balanced design makes CHArmacy® suitable for practitioners seeking predictable shaping, durable results, and a natural post-treatment appearance—without compromising affordability or clinical performance. For inquiries about our product range, don’t wait to contact us.

Frequently Asked Questions


Are calcium hydroxylapatite fillers reversible?

Unlike hyaluronic acid fillers, CaHA fillers are not enzymatically reversible. Proper patient selection and precise injection technique are essential.


Do CaHA fillers look natural?

When placed at appropriate depths, CaHA fillers produce firm yet natural-looking results that evolve gradually as collagen forms.


Who is an ideal candidate for CaHA fillers?

Patients with moderate volume loss, skin laxity, or contour deficiency who desire longer-lasting results may benefit from CaHA fillers.
