CaHA is a unique calcium hydroxylapatite-based dermal filler (known commercially as Radiesse®) designed for the reduction of moderate to deep lines, lifting and contouring with collagen-based volume enhancement, and for long-term improvement in skin quality.
It is a semi-permanent filler that is made with calcium-based microspheres (calcium hydroxylapatite-CaHA) suspended in a water-based gel. The gel is dissipated in vivo and replaced with soft tissue growth, while the calcium hydroxylapatite remains at the site of injection. This results in long-term―yet non-permanent―restoration and augmentation.

CaHA dermal collagen fillers are indicated for subdermal injection for the correction of moderate to severe facial wrinkles and folds, for restoration and/or correction of the signs of facial fat loss in the cheek area and lower face.
This product is indicated in people with facial lipoatrophy due to human immunodeficiency virus (HIV).
CaHA is also indicated for the rejuvenation of the hand.
CaHA dermal collagen filler (known commercially as Radiesse®) is a unique product in that it provides both volume replacement and collagen bio stimulation.
A highly viscous gel, this product provides long lasting aesthetic improvements.
CaHa injections are very popular in the United States and worldwide. As it is a very volumizing product, it is used for deep volume loss and facial contouring. It’s often a product of choice to use for jawline contouring, particularly in the male patient.
CaHA dermal collagen filler (known commercially as Radiesse®) is also great product to use for volumization of the back of the hands.
Unlike HA fillers, (hyaluronic acid) CaHA is NOT indicated for injection in the lips or perioral area (around the mouth).
Results are long lasting and typically last over one year.
More recently, CaHA has been used to improve skin laxity.
By stimulating collagenosis in the injection site areas, the quality of the skin becomes firmer and smoother.
The use of CaHA in this fashion offers patients a more global treatment rather than local filling and volumization. As the product can be more easily spread under the skin, a general skin tightening with progressive, natural, and discrete volume gains is attained.
CaHA is a bio-stimulating dermal filler that not only provides immediate volume but also stimulates collagen and elastin production, making it an excellent choice for skin regeneration. The Calcium Hydroxylapatite (CaHA) microspheres, which act as a scaffold encourages natural tissue regeneration.
- Immediate Volume Restoration: The gel carrier provides instant lifting and filling effects.
- Collagen & Elastin Stimulation: Over time, the CaHA microspheres integrate into the tissue, triggering fibroblast activity to generate new collagen and elastin, improving skin quality.
- Stimulates Collagen & Elastin Production: Unlike HA fillers that mainly add volume, CaHA dermal collagen filler (known commercially as Radiesse®) promotes long-term skin renewal.
- Improves Skin Firmness & Texture: Ideal for sagging skin, crepey texture, and skin laxity.
- Long-Lasting Results: Typically lasts 12-18 months as it encourages natural collagen formation.
- Versatile Use: Can be injected deep for volume or diluted for skin rejuvenation (Radiesse ®hyperdilute).
- Biocompatible & Safe: Made of naturally occurring CaHA, which eventually metabolizes into the body.
Treatment applications of Radiesse® for skin regeneration
By diluting CaHA dermal collagen filler (known commercially as Radiesse®) with saline and lidocaine, it becomes more fluid, allowing for widespread collagen stimulation rather than just volumizing.
Best for:
- Crepey skin on the face, neck, chest, and hands
- Skin tightening for inner arms, abdomen, knees, and buttocks
- Improving skin texture, fine lines, and elasticity
Areas that can be injected successfully include the neck and the décolletage, arms, abdomen, knee areas, buttocks and thighs. This provides a redensification of the skin and is particularly interesting to use in patients with thin skin.
Excess skin will not disappear but will be less visible and tighter due to the stimulation of collagen and elastin.
By treating these areas, the local aged appearance can be improved by CaHA-generated collagen stimulation.
CaHA dermal collagen filler (known commercially as Radiesse®) can be used to improve the look of cellulite in the leg and buttocks area. By creating a redensification in the area, the appearance of unevenness can be reduced.
These results are due to the biostimulatory effect of this injectable.
Multiple sessions are required to create desired results.
Note that currently in Canada, injections on the body for skin rejuvenation are off label.
