Cellulite is the lumpy, irregular fatty deposits that are found under the skin. The most common areas of the body affected by cellulite are the buttocks, hips, thigh and sometimes the lower abdomen, nape of the neck, and upper parts of the arms.
To test for cellulite, lightly pinch or press an area of tissue between your thumb and finger (or in a larger area, between the palms of your two hands). Normal fat appears fairly smooth, but cellulite will reveal dimples or ripples -- like the skin of an orange. Cellulite tissue is also more sensitive and can feel cold to the touch. It might appear whiter than the rest of your skin.
