Liquid Collagen Part 1: How CaHA Biostimulators Restore Facial Volume

What is CaHA (Calcium Hydroxylapatite)?

Calcium Hydroxylapatite (CaHA) is a type of collagen biostimulator that offers both immediate and long-term benefits. It consists of calcium-based microspheres suspended in a smooth gel, providing instant structure while stimulating your body's natural collagen production over time.

How Does CaHA Work?

When CaHA is introduced into the skin, it works in two phases:

    • Immediate Effect: The gel provides instant volume and structure to the treated area
    • Long-term Effect: The calcium microspheres stimulate fibroblasts to produce new collagen, which continues even after the gel is absorbed

This dual-action approach means you see results right away, with continued improvement over the following months.

Benefits of CaHA Treatment

    • Immediate visible results
    • Stimulates natural collagen production
    • Results typically last 12-18 months
    • Natural-looking enhancement
    • Biocompatible and gradually absorbed by the body

Best Treatment Areas for CaHA

Cheek Augmentation

CaHA is excellent for restoring volume to flattened or sunken cheeks, creating a more youthful facial contour.

Jawline Definition

For those seeking a more defined jawline without surgery, CaHA provides structure and definition along the jaw.

Hand Rejuvenation

The hands often show signs of ageing early. CaHA can restore volume to the backs of hands, reducing the visibility of veins and tendons.

Nasolabial Folds

Deep lines running from the nose to the corners of the mouth can be softened with CaHA treatment.
