Not Likely to Work
Cellulite exists due to fibrous bands that pull down the overlying tissue leading to swiss cheese appearance. Unfortunaly, its not caused by a hole that can just be filled. Treatment modalities, although not as great, mainly target the subcutaneous tissue to either release those bands or tighten the tissue surrounding them so that the depression is smoothened. Restylane will not work and so will its thicker cousin, Macrolane.
