Before we talk treatment, we have to discuss what cellulite exactly is. Cellulite is the visualized interaction of gravity’s influence, affect and consequences on the interactions between skin, underlying connective tissue attachments, and deeper tissues of fat, muscle and fascia.
The fewer (looser) the connective tissue (fibrous) attachments the looser the cellulite. The longer, lower and larger the column of tissue (thighs) the greater the chance for cellulite.
Genetics and age influence greatly the propensity for (or lack thereof) cellulite. Thin skin and fatty tissue show it far worse. Thick skin with little fat and good attachments rarely show cellulite.
The treatments therefore focus on diminishing the variables that can be addressed. Lifting tissues and/or tightening (tummy tuck, body lift, thigh lift, and arm lift) serve to reduce or eliminate cellulite. Reduction of fat volume can aide in reducing cellulite; liposuction and Coolsculpting can both achieve this to varying degrees.
In conclusion, there is no panacea, no magic bullet, no simple solution, but improvements are achievable.
