Calcium Hydroxylapatite (CaHA) — Treatment Overview
1. General Information and Description
Calcium hydroxylapatite (CaHA) is a biocompatible injectable material used in aesthetic medicine to support facial rejuvenation, improve skin quality, and restore or enhance facial contours. CaHA is naturally similar in composition to minerals found in the body and is commonly formulated as microspheres suspended in a gel carrier.
Depending on the formulation and treatment technique, CaHA may provide immediate structural support and contouring, while also stimulating the skin’s natural collagen production over time. This allows CaHA to address both facial volume and skin quality, with results that can develop gradually as collagen remodelling takes place.
CaHA may be used in areas such as the cheeks, jawline, chin, lower face, and other areas where improved definition, support, or skin firmness may be desired. Treatment areas and techniques are selected according to the individual’s facial anatomy and aesthetic goals.
2. How It Works
CaHA is injected into targeted areas using a fine needle or cannula. The gel carrier can provide initial volume and structural support, helping to improve facial contours following treatment.
Over time, the CaHA microspheres act as a biostimulatory scaffold, encouraging the body’s natural collagen production. As new collagen forms around the treated area, the skin may gradually appear firmer, smoother, and more supported.
The treatment technique, depth, amount, and dilution of CaHA can be customised depending on the area being treated and the desired outcome. Higher-concentration formulations may be used when structural support or contouring is desired, while appropriately diluted formulations may be used to focus more on skin quality and collagen stimulation.
3. What to Expect and When Results Appear
A CaHA treatment typically takes around 30 to 60 minutes, depending on the number of areas being treated. A topical or local anaesthetic may be used to improve comfort during the procedure.
Some patients may experience temporary swelling, redness, tenderness, bruising, or mild discomfort following treatment. These effects generally improve as the treatment area recovers.
Some improvement in contour or volume may be visible shortly after treatment due to the gel carrier. However, the biostimulatory effects develop gradually as collagen production and tissue remodelling take place. Visible improvements in skin firmness and quality may become more apparent over the following weeks to months.
The duration of results varies depending on factors such as the formulation used, treatment area, treatment technique, individual response, and lifestyle. Some patients may benefit from additional treatment sessions depending on their treatment goals and the assessment of their medical practitioner.
4. Who Is a Good Candidate
CaHA may be suitable for individuals who:
• Wish to improve facial definition and contour
• Are concerned about mild to moderate facial volume loss
• Wish to support natural collagen production
• Are concerned about reduced skin firmness or elasticity
• Want to improve overall skin quality and texture
• Prefer a treatment that can provide both structural support and gradual biostimulatory effects
• Are looking for a minimally invasive approach to facial rejuvenation
A consultation with a qualified medical professional is recommended to assess facial anatomy, skin condition, treatment goals, and suitability for CaHA treatment. Individual results and treatment requirements may vary.
