Cellulite is fat that collects in pockets under the skin. Collagen fibers that connect fat to the skin can stretch, break down or pull tight, allowing the fat cells to bulge out and become visible. This gives cellulite its characteristic dimpled appearance that's sometimes described as the orange peel effect. Cellulite can get worse during pregnancy, but if you lose weight gradually after your baby is born, it may get better again afterwards.
