Yes, there’s superficial (subcutaneous) fat and deep (visceral) fat. Subcutaneous fat is located between your skin and your abdominal muscles and can be altered by liposuction. Deep fat is located behind the muscles inside your abdominal cavity, around your intestines and organs. Liposuction only treats subcutaneous, but VASER Hi-Def Lipo can treat this subcutaneous fat in all its layers to give definition. Deep fat loss occurs with diet and exercise. Excessive internal or deep fat can cause protuberance of the abdominal wall, much like pregnancy does. Men tend to have more internal or deep fat than women.
