Calcium hydroxylapatite filler is a dermal filler composed of tiny calcium-based microspheres suspended in a gel carrier. When injected into the skin, it provides immediate volume while also stimulating collagen production over time, creating a dual mechanism for maintaining results. The most common brand is Radiesse. It is typically used to restore volume in the face, neck, and hands.

This filler works well for people seeking volume restoration in areas with moderate to significant loss, particularly the hands and lower face. It is generally suitable for those who prefer a longer-lasting option than hyaluronic acid fillers but may want to avoid permanent implants. A qualified provider will assess your skin quality and specific concerns to determine suitability.

The procedure typically takes 15 to 30 minutes. Your provider will cleanse the treatment area and may apply a topical anesthetic or use a numbing cream. The filler is then injected strategically into the targeted areas, with results often visible immediately.

Most people experience minimal downtime. Some mild swelling, redness, or bruising may occur at injection sites and usually subsides within a few days. You can typically resume normal activities right away, though strenuous exercise may be best avoided for 24 to 48 hours.

Results appear immediately after injection and improve over the following weeks as collagen stimulation takes effect. The filler gradually breaks down over time, with results typically lasting 12 to 18 months depending on individual metabolism and the treatment area. Touch-up injections can maintain the effect.
