Cellulite is French word that means inflammation or infection in the subcutaneous fat. The word appeared in the English language in the 1920 s and became popular since 1960s. The condition now refers to the dimpling and rippling of the skin of the lateral thighs, hips and abdomen. It happens in women, but can also happen in men who suffer from androgen deficiency. So the female hormones play a role. Anatomically it is caused by the attachment of the superficial fascia system to the dermis when the superficial fatty layer grows and creates bulges in areas where there is no retaining ligaments between the superficial fascia and the dermis. It can also be caused by skin laxity. As the skin falls by gravity the fibrous attachments to the underlying fascia create the dimpling and rippling. In this case the appearance can be improved by tightening the skin. This condition is mostly related to the loss of skin elasticity which comes with aging and sun exposure, and in my opinion is not true cellulite.
