Collagen biostimulatorHyperdilute Radiesse is calcium hydroxylapatite thinned with saline and lidocaine, then spread as a thin layer beneath the skin. Diluted this far it adds no shape — it stimulates collagen and elastin, which makes it a treatment for skin quality rather than contour.
Radiesse is a gel suspension of calcium hydroxylapatite microspheres. At its standard concentration the gel carrier gives immediate volume and the microspheres drive a collagen response behind it, which is what makes it useful for a jawline or a chin.
Diluted several times over with saline and lidocaine, the same product stops behaving like a filler. There is no longer enough material in any one place to create shape. What remains is the biological signal — and spread as a thin subdermal sheet it reaches a far larger area of skin than a filling injection ever would.
The published work on hyperdilute CaHA describes new collagen and, unusually among injectables, new elastin as well. Elastin is what gives skin its recoil, and it is the reason crêping on the neck and décolletage responds to this when it does not respond to volume.
These are regions where filler is the wrong idea and lasers are often too aggressive for the skin that is left. That gap is most of the reason hyperdilute CaHA exists.
The product is placed as a thin fan through small entry points, then spread evenly. Immediately afterwards the area may look faintly full — that is the diluent, and it is gone within a day or two. Nothing is meant to be visible at that stage.
Collagen and elastin take time. The first real change tends to arrive at two to three months, which is also the usual interval before the next session. Most people are treated two or three times; how many is a judgement made on the skin in front of you rather than a fixed package.
Bruising at the entry points and short-lived swelling are the common events. Because calcium hydroxylapatite cannot be dissolved the way hyaluronic acid can, placement matters: the technique depends on staying in the correct plane and distributing evenly, which is the main thing that separates a good result from a lumpy one.
It is also worth being clear about scale. Hyperdilute Radiesse improves the quality of skin. It does not lift a jawline that has descended, and it will not remove an established deep crease.
Questions
It is the same product at a different concentration, used for a different purpose. Undiluted Radiesse adds volume and definition where contour is missing. Hyperdilute Radiesse is thinned with saline and lidocaine and spread thinly, so it adds no shape at all and works purely on skin quality.
Around two to three months, because the result depends on new collagen and elastin being made. Any fullness in the first day or two is the diluent, not the result.
Those are two of its most common uses. Crêped, thinned skin on the neck and décolletage responds to the collagen and elastin stimulus in a way it does not respond to volume.
Usually two or three, spaced a month or more apart. The number depends on the area and how thin the skin has become, and is decided at the assessment.
No. Unlike hyaluronic acid filler there is no enzyme that dissolves calcium hydroxylapatite; it resorbs on its own over many months. At hyperdilute concentrations there is no shape to correct, which is part of why the dilution is used.
Bring your concern rather than a treatment name. The assessment decides what is actually indicated, and what is not.
