Facial aging; It develops due to the thinning of the skin and loss of elasticity as dermal collagen, hyaluronic acid and elastin decrease over time. The intrinsic aging process is accelerated by other external factors such as sun damage and smoking, resulting in facial lines and wrinkles. Muscle contraction that causes facial expression, especially in the upper third of the face, contributes to the formation of wrinkles. These dynamic wrinkles are usually treated with botulinum toxin injection. Volume loss and laxity are more evident in the lower two-thirds of the face, and dermal fillers are commonly used in this area. These lines and wrinkles, also called static lines, are typically observed during rest. Facial volume loss is also the result of resorption of facial bones and reduction of subcutaneous adipose tissue and fat pads. With age, facial contours change from high cheeks and a small chin to flattening of the cheeks and a clearing of the under-chin and neck area.
