Calcium Hydroxyapatite (CaHA) is a collagen biostimulator made up of tiny, naturally occurring minerals found in our bones and teeth; when injected into the skin and combined with Hyaluronic Acid (HA), it provides immediate hydration, plumping, and lifting from the HA while the CaHA microspheres work beneath the surface over the following months to stimulate collagen production, rebuild skin structure, improve firmness, and restore lost volume naturally.
Yes, it’s a minimally invasive procedure. Linerase is administered through microinjections, and a numbing cream is applied beforehand to ensure comfort. Most patients experience only mild discomfort, such as a slight pinch or pressure during the session, which typically lasts about 30 minutes.
Visible results usually appear within 2–4 weeks after treatment. A typical protocol involves 2 to 4 sessions, spaced about 2 weeks apart, for optimal collagen regeneration. Results can last between 6 to 12 months, and maintenance treatments are recommended to prolong skin improvement.
Local anesthesia could be used before the injections. Ice could be applied during and after treatment to minimize discomfort.
Yes. Linerase is CE-certified in Europe and supported by clinical studies for its safety and efficacy. The collagen used is biocompatible and highly purified, which minimizes the risk of allergic reactions. It contains no synthetic chemicals, making it suitable even for sensitive skin.
