Hi, this is Dr. Yuki. In the world of aesthetic treatments, maintaining youthful, firm skin is a top priority. One of the remarkable substances used to achieve this goal is Calcium Hydroxyapatite (CaHA), a biocompatible material that not only enhances facial contours but also thickens the dermis over time. But how exactly does it work?
What is Calcium Hydroxyapatite?
Calcium Hydroxyapatite is a naturally occurring mineral found in our bones and teeth. In the field of dermatology, it’s used in a specially formulated injectable known as Radiesse®. Unlike hyaluronic acid fillers that primarily add volume, CaHA is unique in its ability to stimulate collagen production, providing both immediate and long-term benefits.
How Does CaHA Thicken the Dermis?
- Immediate Volume and Support: When CaHA is injected into the skin, the tiny calcium microspheres are suspended in a gel carrier, which provides immediate volume and support to the treated area. This helps to lift and contour the skin, reducing the appearance of wrinkles and folds.
- Collagen Stimulation: Over time, the gel carrier is absorbed by the body, but the calcium microspheres remain. These microspheres act as a scaffold, stimulating the production of new collagen—the protein responsible for the skin’s strength and elasticity.
- Dermal Thickening: As collagen levels increase, the dermis—the thick, protective layer of the skin—becomes denser and more resilient. This thickening effect not only improves the skin’s texture but also enhances its ability to withstand the signs of aging. The result is firmer, more youthful skin that continues to improve over several months.
- Long-Lasting Results: The benefits of CaHA are not just immediate but also long-lasting. The newly formed collagen helps maintain the skin’s structure, with results that can last up to a year or more, depending on the individual and the area treated.
