With aging, there are multiple internal and external factors that are associated with age-related changes in skin and soft tissue. As Plastic Surgeons, we very commonly evaluate and treat elderly patients, often offering ‘anti-aging’ treatments. An understanding of the science behind aging as well as common patterns of change seen in soft tissue may allow us to refine our treatments. This review provides an overview of mechanisms underlying aging, as well common clinical scenarios with aging regarding anatomic sites commonly treated by Plastic Surgeons including the face, breast, and abdomen. Separately, we discuss aging associated changes to specific tissue types, including skin, fat, muscle, and bone. Knowledge of factors related to aging and concepts related to safe interventions to reverse or mitigate age-related changes and integral to our ability to care for the elderly population.
