Cellulite is nothing but normal fat tissue, visible as bumpy, uneven skin due to breakdown of connective tissue. It doesn't look good, but is perfectly normal, and more than 90% women have it. It is not harmful in any way, except perhaps to a model's livelihood. Still, many women hate it, as it makes them feel unattractive and self-conscious. The fact that it is impossible to get rid of, and even skinny women get it, just makes it even more unpopular.
