The fat that collects right under your skin is called cellulite. It usually appears as dimples or lumpy skin most commonly on your butt, belly, and thighs. How much cellulite you have can depend on many different factors. While what you weigh and the amount of fat you have on your body are definite factors, some factors that you can’t control like genetics, age, the thickness of your skin, and your gender could all impact the cellulite on your body. “People of all weights and sizes can have cellulite,” “even thin people can have it.”
