Cellulite is the cottage cheese appearance to fatty areas, especially thighs and buttocks. It is more common in women, and is thought to be affected by female hormones. Cellulite is small herniations of superficial fatty tissue, and as the fibrous septa of the skin weaken, then the herniation, i.e., bulging of fat lobules, increases. Most treatments that are effective for cellulite deliver heat to the skin septa and induce collagen formation or thickening of these septa; this helps keep the fat lobules from protruding, i.e., herniating.
