As we age, our facial characteristics change due to the effects of gravity, signs of aging, sun exposure, and facial fat. In addition, all elements of the face experience atrophy, including our bone structures, excess fat, and loose skin, resulting in an overall deflation of the face and the appearance of sagging skin on a skinny, bony frame. Facelifts are also an option for individuals recovering from a facial nerve injury, in which case facial rejuvenation surgery will help them regain their lives before the trauma. Your surgeon may have you undergo a physical exam before you are considered a candidate for cosmetic surgery.
