What is injectable calcium hydroxylapatite?
As part of the aging process, the skin, bones, fat, and muscles in our faces begin to thin and shift. These changes result in facial wrinkles, folds, laxity, and/or loss of volume. Injectable calcium hydroxylapatite (CaHA) filler, Radiesse, is a biocompatible, dermal filler which is FDA approved to improve the appearance of moderate to severe facial wrinkles and folds, such as the nasolabial folds. It can also be used to improve the signs of facial fat loss associated with the HIV virus. CaHA is available with and without lidocaine. Lidocaine is an anesthetic used to reduce pain and improve patient comfort during the injection process.
First, your doctor marks the areas to be injected. Topical or injection numbing medication may be used for added comfort prior to your procedure. Next, CaHA is injected into the skin. CaHA produces immediate results and over time can also increase collagen production in the areas injected. The effects of injectable CaHA typically last about 12 months. After that time, additional injections are required to maintain the effects.
What should first be done before considering injectable calcium hydroxylapatite?
First, an ASDS dermatologist will review the patient’s medical history and examine the condition to be treated. Areas to be treated should be kept clean. If there is a skin infection, then treatment needs to be postponed until it resolves. Patients who take blood thinners (such as aspirin, ibuprofen, and certain herbal medications) should stop them two weeks prior to injection with the approval of their prescribing doctor.
