Skin lumps and dimples are referred to as cellulite. Cellulite is also referred to as orange-peel skin, cottage cheese skin, hail damage, and the mattress phenomenon, among others.
It is more common in women because of the different distributions of fat, muscle, and connective tissue in women’s bodies.
Cellulite’s cause is unknown. It is composed of fibrous connective cords that connect the skin to the underlying muscle, with fat filling the space between. As fat cells grow, they push up on the skin, pulling the long, stiff cords downward. This results in an uneven or dimpling surface.
