At BOC Sciences, the preparation of CaHA microspheres follows a highly controlled and precise process, ensuring consistent quality. Each step is meticulously managed to meet the strict requirements of both cosmetic and medical applications, guaranteeing optimal performance in dermal fillers and bone regeneration treatments.
Preparation of Calcium and Phosphorus Solutions
Calcium and phosphorus sources are prepared separately as solutions. An electrolyte is added, and the pH is adjusted to mildly acidic. Electrochemical deposition forms needle-like, submicron/nano-sized HA particles.
Grinding and Slurry Formation
The primary HA product undergoes grinding and crushing, then mixed into a slurry to ensure uniform consistency for the next steps.
Spray Drying
The slurry is spray-dried to form rough HA microsphere precursors with controlled particle sizes, suitable for large-scale production.
Calcination
The microsphere precursors are heat-treated at high temperatures, enhancing crystallization and structural integrity while improving stability.
Sieving and Separation
After calcination, the HA microspheres are sieved to remove any irregular particles, ensuring only uniform and high-quality microspheres for further use.

Key Applications of CaHA Microsphere Preparation
Due to its biocompatibility, biodegradability, and mechanical adaptability, calcium hydroxyapatite microspheres have shown broad potential in medical and aesthetic fields. The key technological breakthroughs come from precision preparation processes, such as electrochemical deposition and stepwise calcination.
Facial Fillers and Contouring
CaHA microspheres (30-35μm) provide instant support through high viscoelasticity (G' value up to 5500Pa) and stimulate type I/III collagen regeneration, making them ideal for filling mid-face hollow areas like nasolabial folds and cheeks.
Skin Barrier Repair
Nano-sized CaHA microspheres (200-500nm) penetrate the epidermal layer, adsorb free radicals through their three-dimensional pores, and promote keratinocyte migration, accelerating skin barrier repair after procedures like phototherapy or for sensitive skin.
Bone Defect Repair
As biomimetic bone material, CaHA microspheres (Ca/P ratio 1.67) closely match the human bone matrix. Using 3D printing, they form porous scaffolds that promote osteoblast differentiation and are used in alveolar bone reconstruction and fracture defect repair.
Chronic Wound Healing
Microspheres loaded with antimicrobial peptides or growth factors (e.g., EGF) use sustained-release mechanisms to prevent infection and accelerate angiogenesis, suitable for treating hard-to-heal wounds such as diabetic foot ulcers and burn injuries.
Drug Delivery System
CaHA microspheres, modified with surface coatings like carboxymethyl cellulose, can load chemotherapeutic agents or protein-based drugs, reducing burst release risks. pH-responsive delivery enhances targeted release, improving the precision of tumor treatments.
Dental Repair
CaHA microspheres (particle size<20μm) are sprayed onto implant surfaces to improve osseointegration and reduce post-operative loosening risks. They can also be used as dentin desensitizers, closing dental tubules and promoting remineralization.
Joint Lubrication
CaHA microsphere formulations combined with hyaluronic acid are injected into joint cavities to reduce friction through mechanical lubrication. They release calcium and phosphate ions to stimulate chondrocyte proliferation, supporting early-stage osteoarthritis treatment.
Anti-Aging Combination Therapies
When combined with botulinum toxin or collagen, such as the “CaHA filling + botulinum toxin wrinkle reduction” regimen, they provide simultaneous improvements for both static depressions and dynamic wrinkles. Alternatively, combined with hydrating treatments, they enhance skin’s moisture retention.
FAQs
What type of collagen does CaHA produce?
CaHA stimulates the production of Type I and Type III collagen, which are essential for skin structure and repair. Type I collagen provides strength and support, while Type III collagen aids in skin regeneration and elasticity.
What is the difference between PLLA and calcium hydroxyapatite?
PLLA (Poly-L-lactic acid) and CaHA differ in composition and mechanism. PLLA is a biodegradable synthetic polymer that gradually stimulates collagen production, while CaHA is a naturally occurring mineral that provides immediate volume and promotes collagen synthesis over time.
How long do the results of CaHA injections last?
CaHA injections typically last between 18-24 months, depending on the treatment area, individual factors, and lifestyle. The results are gradual, with long-lasting effects due to collagen stimulation and skin regeneration.
Is CaHA safe for facial contouring?
Yes, CaHA is safe for facial contouring. Its biocompatibility and ability to stimulate collagen production make it a popular choice for non-surgical procedures like cheekbone enhancement, chin reshaping, and jawline definition.
What are the benefits of CaHA for wrinkle treatment?
CaHA is effective in treating wrinkles by providing immediate volume and stimulating collagen production. It can reduce the appearance of fine lines and deep wrinkles, particularly in the mid-face area, offering long-lasting rejuvenation.
