CaHA Skin Boost (Hyperdilute Calcium Hydroxylapatite)

Treatment details: CaHA Skin Boost (Hyperdilute Calcium Hydroxylapatite)

Calcium hydroxylapatite used at standard concentration adds volume, but diluted well beyond that it behaves differently: the microspheres disperse through the dermis and act as a scaffold for new collagen instead of filling a space. That is why it suits patients who want firmer skin without any change to facial shape. The photograph is immediately after treatment, and the collagen response builds over the following months. Diluting calcium hydroxylapatite well beyond its standard concentration changes what it does. Instead of adding volume it disperses through the dermis and acts as a collagen stimulant, which is why the effect appears over months rather than on the day.

Diluted calcium hydroxylapatite is placed in a fine layer, so temporary bumps, redness, and bruising at the entry points are usual for two to four days. Firmness or small nodules can develop, particularly where the material sits too shallow or over active muscle, and these may take months to resolve. This material cannot be dissolved with hyaluronidase, so any irregularity is managed by massage, injections to soften it, or waiting for absorption. Change appears gradually.
