Cellulite

In women, fat cells located close to the skin are enclosed in elongated, thin "compartments" formed by connective tissue. When these compartments are pushed upwards by swollen fat cells, the surface of the skin takes on the dimpled appearance known as cellulite. In men, the connective tissue forms a more resistant network of diagonal collagen fibers, which prevents fat cells from pressing against the skin, keeping it smooth. This explains why men rarely develop cellulite.
