Scientific evidence suggests that cellulite  affects many women and can be very difficult to correct. “Orange peel skin” is thus called due to its appearance and texture and  can affect all body shapes and sizes and must not be confused with normal fat and assume that cellulite is directly a result of overeating or lack or exercise. When you diet your body automatically burns its own reserves of fat but cellulite is fat stored in the dermal layer of the skin and the body cannot effectively process it as fuels thus it remains. Causes of cellulite are many. The first cause is linked to the connective tissue between the skin and the fat compressing. The second cause is when fat cells push against the skin. Over time your body naturally produces less collagen and elastin and as women age and produce less oestrogen and tissue blood supply is decreased-  this reduces the amount of collagen in the connective tissue fibres. When these tissues weaken the bulging worsens causing  the orange peel effect as some skin is now being pushed out while other sections are being pulled in. 
Cellulite is characterised by large metabolically stable adipocytes that are limited to lower body areas such as thighs, buttocks and legs. 
There are multiple stages of cellulite and cellulite should be treated according to the stage that it is in. Often lifestyle choices can help to reduce the appearance as can many treatments on the market however for more permanent results patients require more intensive treatment. Liposuction and/ or fat grafting can greatly improve the condition.
