Elements that seem to be involved in cellulite's appearance are: adipocyte • hypertrophy, connective tissue abnormalities, fi brous septa, and hormonal in fl uences.A new cellulite severity scale (CSS) and classi fi cation was recently devel-• oped. The CSS considers relevant morphological aspects, such as the number of evident depressions, depth of depressions, aspect of raised areas, grade of laxity, fl accidity or sagging skin, and the previous cellulite scale. Diagnosis is mainly clinical although magnetic resonance imaging, laser • Doppler fl owmetry, thermography, and ultrasound can be used for research purposes.A series of treatments can treat or improve the appearance of cellulite, such • as topical products, oral supplements, devices (mechanical massage, lasers, light sources, radiofrequency, and other technologies), and surgical procedures (Subcision ® and liposuction).
