The fats just below the skin surface push against the tissue which results in the skin surface having that dimpled look common of cellulite. In reality, nobody knows the real reason why some people accumulate these fats and not others, but there are some factors that health experts are considering such as the structure of the fat cells or toxins that enter the body.
This problem usually comes naturally with aging and similar to wrinkles that form in the face, it is actually the result of lower levels of collagen and elastin in the skin. It is classified as a hormonal imbalance experienced by women and seldom appears on males as normally fat stored in the thighs and buttock is the same as fat stored all over the body so no difference is observed.
