Radiesse works in two phases. First, the gel component provides immediate volume and wrinkle correction. Then, over time, the CaHA microspheres stimulate the body’s natural collagen production, helping the skin rebuild strength and structure from within. This dual-action approach leads to results that improve over time, lasting up to a year or more. When used in the neck area, especially when paired with neurotoxin to reduce the muscle pull of the lower face and neck and NouvaDerm for skin texture refinement, the results are visibly smoother, firmer, and more youthful. This combination treatment is ideal for clients looking for a non-surgical solution to neck aging.
