Cellulite is a purely cosmetic problem, not a disease or health condition, as many people think. It looks like the notorious orange peel, and all the bumps and lumps become even more noticeable when the skin is squeezed. The cause of cellulite is the structure of the subcutaneous fat tissue. Most often, cellulite appears on the buttocks, thighs, abdomen, but can even occur on the arms and chest.
