Calcium hydroxylapatite (CaHA) is a soft tissue filler used in cosmetic procedures to fill wrinkles and folds in the skin, such as nasolabial folds. CaHA fillers contain smooth, spherical microparticles that are similar to the mineral content of human bone. When inserted into the dermis, the microparticles stimulate the skin's natural production of collagen and hyaluronic acid. This helps support and train the skin to retain its volume over time.
Composition and Characteristics of CaHA
CaHA fillers are composed of smooth spherical microparticles that mimic the composition of human bone. Bone is made up of calcium phosphate in the form of hydroxyapatite. Hydroxyapatite gives bone its rigidity and strength. Likewise, CaHA filler particles help restore volume and fullness to the skin.
The microparticles in CaHA fillers are about 25-45 microns in size. This is less than half the size of a grain of salt. Their smooth round shape helps CaHA particles easily integrate into the skin's deeper layers without clumping or migrating. The microparticles are also biocompatible, meaning the body accepts and incorporates them well with minimal irritation.
How CaHA Fillers Work
When injected into wrinkles and folds in the skin, CaHA microparticles stimulate the skin's collagen production in two ways. First, the calcium and phosphate components of the particles trigger the skin's fibroblasts, which are cells responsible for generating new collagen fibers. Second, the volume added by the microparticles trains the skin to think it needs more support. This volume loading cues the body to create and deposit more collagen and hyaluronic acid where the filler was placed over time.
Results and Longevity
The results of CaHA filler treatments are gradual and natural looking. Full correction of folds and wrinkles may take 4-6 months to occur as the skin produces new collagen in response to the microparticles. During this period, the treated areas may look slightly fuller but the final results will feel softer and more youthful.
The effects of a single CaHA treatment can last 1-2 years on average as the particles slowly and gently stimulate collagen production over time. Some smoothing and correction may be noticeable even years later as the skin retains some of the volume from the initial treatment. CaHA is one of the longest lasting fillers available.
Advantages of CaHA Fillers
There are several advantages that have made CaHA fillers a popular choice for restoring volume and reducing signs of aging:
- Natural looking and feeling results: CaHA particles mimic the skin's natural structural components so the corrections look very natural.
- Gradual effect: The subtle, gradual effect of CaHA is preferable to the overly "done" look of some other fillers.
- Longevity: At 1-2 years per treatment, CaHA offers one of the longest durations of correction available.
- Biocompatibility: The particles are smoothly rounded and well-tolerated by the skin. Side effects are minimal.
- Gradually stimulated collagen: CaHA induces the body's own collagen production over months for an enduring effect.
- Skin reinforcing: It can help reinforce thin, aging skin in areas like the hands over the long term.
- Combined uses: CaHA can be used alone or combined with other modalities like neurotoxins.
Potential Side Effects and Safety
Overall, Calcium Hydroxylapatite (Caha) Fillers fillers are considered very safe. Any side effects tend to be mild and temporary when used as indicated. Potential risks include:
- Bruising or swelling at the injection sites which resolves within a few days.
- Tenderness or itching occasionally reported. Antihistamines can help.
- Lumps or bumps under the skin if too much filler is injected in one area.
- Asymmetry or uneven correction if not inserted precisely enough.
- Telangiectasias or small broken blood vessels may occur but are uncommon.
Serious reactions are rare when treatments are administered properly by an experienced provider. A skin test may be recommended initially for those with sensitivities. The effects are fully reversible either through massage or medical intervention if larger issues occur down the road, making CaHA a reliably safe option.
calcium hydroxylapatite fillers provide an outstanding combination of a natural look and feel along with one of the longest periods of correction available up to two years. CaHA helps reinforce the skin and stimulate its collagen production for gradual but noticeable renewal. Its smooth microparticle composition integrates gently into the skin with very low risk. For those seeking subtle but substantive anti-aging effects, CaHA has become one of the most preferred filler choices.

RADIESSE® is one popular brand of FDA-approved CaHA-based fillers.
It is composed of CaHA microspheres suspended in an aqueous gel carrier.
As these are similar to the minerals found in the body, no allergy testing is needed.
The body absorbs the gel and metabolizes the microspheres, leaving behind only your natural collagen.
