There are also several cosmetic procedures that will help you lose or gain chubby cheeks. Some people are naturally endowed with thinner bone structure and less flesh on their face so their cheeks look slim. However, our subcutaneous fat reduces with age because as we grow older the hyaluronic acid we once produced starts to diminish. Our skin becomes dry and facial volume decreases. Gravity pulls the skin down, resulting in folds and sagging. When volume is restored to a hollow face it usually conveys youth. The simplest and quickest way to restore that volume is with dermal fillers that are specially formulated to replenish volume.
