Injectable wrinkle fillers each have different properties and formulas to help with various issues. Common filler materials include HA (hyaluronic acid), CaHa (calcium hydroxyapatite), poly-L-lactic acid, and PMMA (polymethylmethacrylate). Radiesse uses calcium-based microspheres, which are similar to HA wrinkle fillers since both prompt collagen production in your body. At your appointment, we will explain the different dermal filler brands and assess your skin's volume, laxity, and tone to determine which product will address your unique concerns.
