Calcium hydroxylapatite can give firm structure where it is placed undiluted, or support skin quality when it is diluted. At IN Eternity Clinic the job is decided before the syringe is chosen.

Because it is firmer than most hyaluronic acid fillers, it holds a line well in areas that need definition. The same property is why it is not used in thin, mobile areas such as the lips or directly under the eyes.

Structural use. Undiluted CaHA is placed deep, close to bone, to project the nose bridge or tip, define the chin or sharpen the jawline. The amount is small and the plan is built around the face’s proportions.
Skin-quality use. Diluted or hyperdiluted CaHA is spread in a fan pattern under the skin of the face, neck or arms to support firmness. This is a different procedure with different expectations; it does not change shape.
“The same syringe can sharpen a jawline or firm the skin of the neck. Which job it does depends on the dilution, so that is decided first.”
Bruising, swelling and tenderness are common. Nodules can form, particularly if the product is placed too superficially. As with any filler, there is a small risk of the product entering a blood vessel, which is why anatomy, technique and the doctor’s experience matter, and why Radiesse is not used in the lips or tear troughs.

Not with hyaluronidase, which only breaks down hyaluronic acid. That is why amounts are conservative and placement is planned with care.
It can be. For non-surgical nose shaping Dr Sin Yong usually prefers a structural product such as calcium hydroxylapatite or polycaprolactone rather than hyaluronic acid alone. Suitability depends on the nose and previous procedures.
Radiesse mixed with more liquid and spread thinly under the skin to support firmness and quality. It does not add shape.
The lips, directly under the eyes and other thin, mobile areas, where a firmer product is more likely to be felt or seen.
It varies between people and areas. It is gradually broken down by the body while the collagen it prompted remains for a time.
