Radiesse: Your Guide to the Collagen-Stimulating Calcium Hydroxylapatite Filler

Radiesse by Merz Aesthetics is an injectable filler made of calcium hydroxylapatite (CaHA), which adds immediate volume and gradually stimulates natural collagen production for facial contouring and hand rejuvenation. In this guide we explain what it is, how it works, its uses, and how long its results last, while stressing that it is a professional medical device administered only by a qualified practitioner and not for self-use.

What is Radiesse?

Radiesse is a cosmetic filler in a 1.5 ml pre-filled syringe, whose active component is calcium hydroxylapatite (CaHA) microspheres within an aqueous gel. It is classed as a “biostimulatory” filler because it does not just fill but stimulates the body to form new collagen. It is made by Merz Aesthetics and administered by a qualified practitioner.

How does Radiesse work?

Radiesse works by two mechanisms: the first is immediate, where the gel provides direct volume that fills wrinkles and restores fullness. The second is gradual, as the calcium hydroxylapatite microspheres act as a scaffold that stimulates fibroblasts to produce natural collagen, so the result improves over time and looks natural. The gel is later absorbed and the microspheres are biodegraded.

Uses of Radiesse

the filler is used to contour facial features and define the cheeks, jaw and chin, fill moderate-to-deep folds and wrinkles such as the nasolabial folds, and rejuvenate the back of the hands. To learn its uses as a filler in detail read Radiesse filler and its uses.

Who is it for?

this filler may suit those looking to contour facial features, improve moderate-to-deep wrinkles or rejuvenate the hands, who are in good general health. But it is not usually used in the lips. A qualified practitioner decides its suitability for each case after assessing the skin, features and expectations, as not everyone is a suitable candidate, and medical evaluation is the basis before any procedure.

A professional procedure only

It is very important that the product is a medical device injected only by a qualified, licensed doctor or practitioner, and is never for self-injection at home. The practitioner determines the injection sites and appropriate technique within a sterile environment, which reduces risks and improves the result. To learn about results and safety see Radiesse results and duration.

How long do results last?

The results of the filler usually last about 12–18 months, and may vary by the treated area, skin type and lifestyle. Because it is a biodegradable, non-permanent filler, the result gradually fades over time, and the session can be repeated with a doctor’s advice when needed to maintain the appearance.

Important warnings

It is preferable to avoid this filler during pregnancy and breastfeeding, with infection or inflammation at the injection site, bleeding disorders, hypersensitivity to any of its components, or a tendency to keloid scarring. Tell your doctor all your medicines, especially blood thinners, before the procedure, and only have the injection with a qualified practitioner.

When to consult a doctor?

Consult a qualified dermatology or aesthetics doctor before the treatment to assess its suitability for your skin and goals, and tell them your medical history, medicines and allergies. If unusual symptoms appear after the injection such as severe pain, color change or persistent swelling, see your doctor right away.
