Having IPL treatment should not damage the results and volume correction you achieved with Radiesse. IPL sources have a penetration in the skin in the range of 1 to 3 mm, depending on whether they contain a majority of light wavelengths in the green spectrum (fotofacial), yellow (hair removal) or red (hair removal, darker skin types). Radiesse is typically injected below this level. But, in addition, radiesse itself is a faintly white powdery suspension that will not be capable of selectively absorbing any of the color wavelengths of the IPL. Similarly, hyaluronic acid fillers being transparent (restylane, perlane, juvederm, hylaform) will not absorb the light of the IPL and will not decay or be destroyed.
