Will reducing body fat reduce face fat?

Yes. When people lose a lot of weight, it can show in many different areas including the face. You have fat cells in all parts of your body. When you lose weight, the fat cells don't go anywhere, they just shrink as they are storing less fat. In older people there is a normal reduction in fat stores with age which can lead to a more aged look. This is where injectable soft tissue fillers have a role.
