Radiesse CaHA Collagen Biostimulator
Calcium Hydroxylapatite (CaHA) microsphere biostimulator utilizing hyper-diluted and structural protocols to rebuild Type I and III collagen, elastin, and extracellular matrix strength.
Treatment Overview & Clinical Mechanism
Radiesse is a regenerative Calcium Hydroxylapatite (CaHA) microsphere biostimulator suspended in an aqueous carboxymethylcellulose gel carrier. When administered in customized hyper-diluted or structural subdermal protocols, CaHA microspheres form a biocompatible scaffold that activates dermal fibroblasts to synthesize Type I and Type III collagen, elastin, proteoglycans, and angiogenesis—restoring structural integrity to lax facial and neck skin.
At ReYeonK Clinic, Dr. Lee Doochan, Dr. Kim Hyunsu, and Dr. Choi Hyunho conduct 1:1 physician-direct consultation and anatomical vector mapping within our Skin Regeneration & Skin Boosters center. Depending on skin thickness and laxity, Radiesse can be tailored alongside Rejuran Healer or Juvelook for comprehensive extracellular matrix renewal.
Ideal Candidates & Target Concerns
- Patients with thinned, lax skin across the mid-face, lower cheeks, jawline, or neck
- Individuals experiencing horizontal neck creases and crepey skin texture from collagen depletion
- Those seeking long-lasting structural elastin and collagen regeneration without overfilled facial contours
- Patients wishing to strengthen the dermal foundation prior to or alongside energy-based lifting
Clinical Specifications & Protocol Summary
| Parameter | Clinical Details |
|---|---|
| Modality / Formulation | Calcium Hydroxylapatite (CaHA) Microsphere Biostimulator |
| Target Layer / Area | Subdermal Plane / Deep Dermis (Lower Face, Cheeks, Jawline, Neck) |
| Typical Session Duration | 30–45 minutes (including topical anesthetic preparation) |
| Recommended Course | 1–2 sessions spaced 3–6 months apart |
| Expected Recovery Window | 2–5 days (mild swelling, tenderness, or transient bruising) |
Step-by-Step Procedure Process
- 1:1 Physician Consultation: Anatomical assessment of dermal thickness, elastin loss, and soft-tissue laxity to determine optimal CaHA dilution ratios.
- Cleansing & Topical Anesthesia: Thorough antiseptic preparation and topical numbing cream application.
- Blunt Cannula Vector Placement: Smooth subdermal fanning delivery using a atraumatic micro-cannula to distribute CaHA microspheres evenly.
- Post-Procedure Molding & Calming: Gentle physician contouring massage and soothing barrier care.
Post-Treatment Care & Clinical Safety Notice
- Avoid intense heat (saunas, hot baths), alcohol, and strenuous cardiovascular exercise for 5 days.
- Refrain from forceful facial massages or pressure on the treated areas for 1–2 weeks.
- Maintain daily hydration and UV protection to support physiological neocollagenesis.
Individual results vary depending on skin condition, tissue metabolism, and lifestyle factors. Potential temporary side effects include localized swelling, bruising, pinpoint erythema (redness), mild tenderness, embossment papules, or rare infection/inflammation, which generally subside within a few days.
Frequently Asked Questions
Q. How does hyper-diluted Radiesse work as a skin biostimulator rather than a traditional filler?
By diluting CaHA microspheres to a customized physiological ratio and fanning them smoothly in the subdermal plane, the focus shifts from localized volume projection to widespread collagen and elastin regeneration.
Q. How long does CaHA-induced collagen remodeling last?
Fibroblast activation begins within 4 weeks and continues building dermal firmness for 12–18 months as the CaHA particles naturally metabolize. Contact our team via Contact Us.
