Radiesse is a non-surgical treatment that injects calcium hydroxylapatite (CaHA) into the skin to provide immediate volume and stimulate longer-term collagen regeneration. It helps to understand before starting that there are two stages of change: the volume you see right after treatment, and the improvement in firmness that develops over the following weeks.
The ingredient is naturally broken down and cleared from the body through a metabolic process that takes about 6 months, and the overall effect is generally reported to last 6–12 months. This article explains how it works, who it suits, and how to care for the skin during the 1–2 weeks after treatment.
What is Radiesse made of, and how does it work?
CaHA microparticles are suspended in a gel carrier. Right after it is injected under the skin, it physically fills hollow areas to create immediate volume. Over the following weeks it moves into a second stage, stimulating fibroblasts to produce collagen, so that skin texture and firmness gradually improve.
A typical hyaluronic acid filler works by drawing in water to add volume. Radiesse, by contrast, encourages the skin tissue itself to produce collagen, and the ingredient is naturally cleared through a metabolic process lasting about 6 months, so it does not stay in the body indefinitely.

Who is this treatment suitable for?
Unlike treatments that aim only at adding volume, Radiesse works by encouraging the skin to regenerate. As a result, it often leaves the impression that the skin's natural firmness has returned rather than that something has been filled in, which can make it a good option for people who value a natural look.
- Concern about an artificial look — for those who prefer natural improvement through collagen regeneration over the filled-in look of fillers
- Volume and firmness together — for those who hope to add volume and improve skin firmness with a single treatment
- Longer — lasting results — for those who want an effect that lasts, generally reported at 6–12 months
- Nasolabial folds, hollow cheeks and drooping mouth corners — for those with sagging and hollowing in several areas that need combined improvement

What should I watch out for after treatment, and when?
Bruising, swelling, mild pain, redness and temporary lumpiness are common reactions while the ingredient settles, and most subside within a few days. However, if pain or swelling lasts a long time, or if you notice changes in skin color or nodules, contact the clinic where you were treated without delay.
- On the day of treatment — wash your face gently with lukewarm water and do not press or rub the treated area
- For 1–2 weeks after treatment — avoid alcohol, smoking, saunas, jjimjilbang (Korean bathhouses), hot baths and strenuous exercise
- Skin care — use moisturizer and a barrier-repair cream consistently, and apply sunscreen when you go out
- Treated area — avoid peeling treatments and scrub products for about one week
