This hybrid injectable treatment combines hyaluronic acid (HA), known for its immediate volumising and lifting properties, with calcium hydroxyapatite (CaHA), a biostimulatory ingredient associated with collagen production.
Together, they offer both immediate support and progressive improvements in skin structure over time.
HACa is a hybrid injectable that combines Hyaluronic Acid (HA) and Calcium hydroxyapatite (CaHA) in a single treatment to provide both immediate and longer-term benefits. Following injection, the HA component acts as a supportive gel matrix that helps restore facial contours and provide an immediate lifting effect in areas affected by age-related volume loss and tissue descent. At the same time, the CaHA microspheres function as a biostimulatory scaffold that is associated with the stimulation of the body’s natural collagen production process.
Over the following weeks and months, new collagen may gradually develop around the treatment area, helping to support skin architecture, improve tissue quality, and enhance firmness and elasticity. This dual-action approach allows HACa to deliver both an immediate visible improvement and progressive tissue remodelling over time, making it a unique option for patients seeking natural-looking facial rejuvenation.

Once injected, the HA component provides immediate structural support, helping to improve facial contours and address areas of volume loss or sagging.

It is designed to work with your natural facial anatomy rather than dramatically alter it. By combining immediate support with gradual collagen stimulation, the treatment helps restore facial contours and improve skin quality in a subtle and balanced way, allowing you to look refreshed and rejuvenated while still looking like yourself.

The CaHA component acts as a collagen-stimulating scaffold. In the weeks and months following treatment, it is associated with the stimulation of your skin's natural collagen production, helping to support skin firmness, elasticity and tissue quality.

Beyond the immediate effects, it supports your skin's natural collagen production over time. As new collagen develops, patients may experience ongoing improvements in skin firmness, elasticity and facial support, helping to maintain a refreshed appearance for longer.

As the HA gradually integrates with the surrounding tissues and the CaHA supports collagen remodelling, patients may notice ongoing improvements in skin quality and facial support over time.

HACa works seamlessly within the MD Codes framework, complementing structural correction with regenerative support. By combining tissue support with gradual collagen stimulation, it enables practitioners to address facial architecture and skin quality within a single, comprehensive treatment strategy.
This treatment may be suitable for patients who are noticing:
• Early to moderate facial sagging
• Loss of jawline definition
• Reduced skin firmness
• Deepening folds and shadows
• Changes in lower face contour with age
Before proceeding with the treatment, our doctor will discuss your concerns and assess whether HACa is suitable for you.
You can expect some bruising and swelling immediately after treatment. However, when the side effects have subsided, you will be able to enjoy natural-looking results that restore volume and reverse signs of ageing at the same time.
HACa Injectable can last at least 12 months, and up to 18 months, depending on the individual. The result is a long-term yet non-permanent restoration and augmentation. The injectable will last for up to 12 months but the skin tightening benefit will remain.
After treatment, your skin may feel lifted, tighter and firmer which can last at least 12 months due to the stimulation of your body's natural collagen production.
There may be slight downtime such as redness, swelling, pain or tenderness depending on individual. These are often mild and typically will subside within 24 to 48 hours.
