The benefits of Radiesse cheek injections are to add volume to the cheeks and make the patient's face look more youthful and vital, according to the National Institutes of Health. It can also be used to lessen the appearance of acne scars on the cheeks. The cheeks tend to lose their plumpness as a result of aging, when the dermis layer of the skin begins to dry out.
Radiesse dermal filler has no latex and is sterile, says NIH. It does not produce fever or other inflammatory responses, is biocompatible, and has been used in cosmetic procedures for over 20 years. It is made of microspheres of synthetic calcium hydroxylapatite suspended in a gel medium of glycerine, sterile water and a bit of carboxymethylcellulose. Radiesse is injected by a 1.3-milliliter disposable syringe, and any leftover material can be kept in the syringe for up to three months for the patient's future use.
After the Radiesse is injected, the gel is broken down, but the carboxymethylcellulose and calcium hydroxylapatite spheres remain, says NIH. Eventually, the carboxymethylcellulose is also broken down and replaced by collagen, which creates a springy layer beneath the top layers of the skin. This process takes about two to three months. The calcium hydroxylapatite spheres are also harmlessly absorbed by the body after a longer time.
