Product Overview

Radiesse is a biocompatible, collagen-stimulating dermal filler engineered to deliver both immediate correction and durable skin quality improvement. Its unique formulation—calcium hydroxylapatite (CaHA) microspheres embedded in a smooth aqueous gel—provides instant lift while initiating a sustained biological response that promotes neocollagenesis. The result is natural-looking contour, improved elasticity and firmness, and visible textural refinement that can last up to 12–18 months, depending on treatment area and individual factors.

Composition & Technology

Radiesse contains CaHA microspheres (typically 25–45 μm) suspended in a carrier gel composed of water, glycerin, and sodium carboxymethylcellulose. The gel delivers immediate volumization and uniform placement, while the spherical CaHA particles function as a three-dimensional scaffold that recruits fibroblasts and supports new collagen deposition. Over time, the gel is resorbed; the CaHA matrix is gradually metabolized into calcium and phosphate ions as newly synthesized collagen replaces the initial volume support.

Mechanism of Action

Immediately after injection, the viscoelastic gel restores volume and softens folds, enhancing contour in areas such as the midface, jawline, and dorsal hands. In the subsequent weeks and months, the CaHA scaffold stimulates fibroblast activity and extracellular matrix remodeling. This controlled biostimulatory phase yields progressive thickening of the dermis, improved skin density, and a smoother surface profile. As the CaHA microspheres biodegrade, the newly formed collagen network maintains a natural, durable result without the feel of a persistent implant.

Indications & Treatment Areas

Radiesse is indicated for the correction of moderate to severe facial wrinkles and folds, including nasolabial folds, and is widely used for structural support in cheeks and chin, mandibular angle and jawline definition, and temple or midface volume restoration when clinically appropriate. In addition, Radiesse is an established option for rejuvenation of the dorsum of the hands, where it replenishes volume, camouflages prominent veins and tendons, and improves the perception of skin quality. Patient selection, facial assessment, and a holistic treatment plan remain essential to achieving balanced, natural outcomes.

Clinical Performance & Longevity

Clinical experience and published evidence support Radiesse’s dual benefit: immediate contouring with a natural, soft feel and a biostimulatory phase that enhances firmness and texture over time. Longevity commonly ranges from 12 to 18 months in facial applications, with variation by anatomical site, injection depth, product volume, and patient metabolism. In the hands, durable improvements are also observed, with high patient satisfaction tied to the subtle, progressive nature of the result.

Technique Considerations

Radiesse can be placed with needle or cannula, using linear threading, fanning, or depot techniques according to the anatomical plane and treatment objective. Depth of placement typically ranges from deep dermis to supraperiosteal levels for structural support, while more superficial planes require cautious techniques to avoid visibility or irregularities. For contouring, precise vectoring and conservative volumes help maintain natural proportions. Adhering to aseptic technique, slow injection with low extrusion pressure, and frequent aspiration or dynamic needle repositioning protocols are standard risk-reduction practices in vascular-rich zones.

Safety, Biocompatibility & Tolerability

CaHA is a long-used, biocompatible biomaterial in medical devices, and Radiesse is fully biodegradable. The most common post-treatment events are mild and transient—erythema, edema, tenderness, or bruising at the injection site. As with all injectable procedures, proper anatomical knowledge and complication management readiness are mandatory. Practitioners should follow evidence-based protocols for vascular safety, product placement, and aftercare, and provide patients with clear guidance on expected recovery and when to seek follow-up.

Contraindications & Precautions

Radiesse should not be used in patients with known hypersensitivity to any component, active infection or inflammation in the treatment area, or in individuals with a history of severe allergies or anaphylaxis without appropriate evaluation. It is not indicated for lip augmentation or periorbital intradermal use. Caution is advised in patients with bleeding disorders, those on anticoagulants, and in high-risk vascular territories. Pregnancy and lactation are generally considered exclusions in line with standard aesthetic-medicine practice.


Formats, Handling & Storage

Radiesse is supplied in prefilled syringes in multiple configurations, including a lidocaine-containing option where available, to enhance injection comfort. Store at controlled room temperature according to the manufacturer’s instructions. Do not freeze. Use appropriate needle or cannula gauges recommended for the target plane and indication and follow lot traceability and disposal protocols consistent with clinic quality systems.

Summary

Radiesse integrates immediate volumizing performance with proven biostimulatory activity to deliver natural contour and progressive skin quality gains. Its CaHA-based scaffold induces new collagen formation as the carrier gel and microspheres are safely resorbed, supporting results that look and feel authentic. For clinics focused on regenerative outcomes and patient demand for longevity with low-maintenance follow-up, Radiesse is a cornerstone injectable across facial sculpting and hand rejuvenation.
