Overview
Calcium hydroxyapatite is an injectable product made of microspheres of a mineral found in bone, suspended in a gel. It works in two ways. It adds volume that is visible straight after the injection, then stimulates collagen and elastin production over the following weeks. The body gradually breaks the product down but, unlike hyaluronic acid, it cannot be dissolved with an enzyme.

Frequently asked questions
When will I see the result, and how long does it last?
The volume is visible straight after the injection. Collagen production then takes over, and the full result shows at around 6 weeks. The effect usually lasts up to about a year, depending on the area treated and the person.
How is it different from hyaluronic acid?
Both add volume. Calcium hydroxyapatite also stimulates collagen production, which makes it suited to areas that need support, such as the cheeks or jawline. However, it is not used on the lips or around the eyes, and it cannot be dissolved with hyaluronidase. The consultation is where the right product for your situation is chosen.
What happens afterwards?
In most cases you can return to your usual activities the same day. Swelling and redness are possible for 72 hours, and light bruising can last 3 to 7 days. For 24 hours, avoid intense exercise, sun and heat.
Do I need to mention it before an X-ray?
Yes. Calcium hydroxyapatite microspheres show up on X-rays, CT scans and mammograms. Tell the doctor or radiologist carrying out the scan that you have had this injection.
Who should not have this treatment?
This product is for adults only. It is not advised during pregnancy or breastfeeding, with an allergy to one of its ingredients or to lidocaine, a clotting disorder or a skin infection in the area. Tell the doctor at the consultation about any autoimmune disease, history of herpes, or permanent filler already injected in the area.
