Radiesse and Sculptra are both injectables that restore lost volume and improve skin appearance, but they work in different ways and use distinct ingredients.
Radiesse is made with calcium hydroxylapatite (CaHA) in a water-based gel. It provides immediate volume by acting as a scaffold beneath the skin, while also stimulating collagen production for longer-term benefits. Over time, the gel is absorbed by the body, leaving behind your own collagen for a natural result.
Sculptra, on the other hand, uses poly-L-lactic acid (PLLA), which also stimulates collagen production but works gradually. It targets the underlying causes of aging, providing subtle and long-lasting improvements. Unlike Radiesse, Sculptra's results develop over time as the body produces more collagen, making it ideal for more gradual rejuvenation.
In short, Radiesse offers more immediate volume with ongoing collagen stimulation, while Sculptra delivers slower, longer-term results by stimulating collagen deep within the skin.
