"Basically, the effect of age and our hormones on our connective tissues, combined with the accumulation of fat in the upper layers of the skin, create the dimpled effect of cellulite. The tightening of the connective tissue, its loss of elasticity, and the accumulation of excess fluid and metabolites, all contribute to the effect of cellulite. Liposuction will not address these problems.
Additionally, liposuction for cellulite is not an effective option because liposuction usually removes fat from a deeper layer of the skin than where cellulite occurs. Cellulite is stored close to the surface of the skin. Whilst the removal of fat from the deeper layers of the skin may have a good contouring effect for some people, for others it may actually make their cellulite look worse."
