Facial optimization is accomplished through the use of minimally invasive cosmetic procedures including injectable and skin resurfacing techniques via the use of toxins, dermal fillers, biomaterials, lasers, and other skin resurfacing devices to improve outcomes. Less invasive than surgery, injectables and skin resurfacing techniques target various facial irregularities including wrinkles and fine lines, decrease in volume and contour, and unwanted fat. Determining the best approach for a given patient involves careful consideration of the patient's health conditions, unique anatomic characteristics, tissue quality, and desired results. Collectively, these procedures aim to optimize facial aesthetics by creating a youthful appearance, enhancing symmetry, augmenting facial contours, and improving proportions of the face and neck. This book entails various modalities in the field of facial rejuvenation with minimally invasive procedures to achieve and maintain a youthful appearance.
