Facial aging begins the day you are born, and proceeds at different rates throughout your life. The face ages in five key ways: Discoloration Skin changes occur, such as brown spots and sallow (yellowish or brownish) color. Wrinkle Formation Wrinkles form from overactive muscles and dehydration, as well as due to loss of a key skin building block called collagen. Volume Loss Volume depletes, causing hollow cheeks and temples due to fat loss and the agerelated breakdown of the underlying facial structure. Loss of Elasticity Skin no longer “bounces back” quickly if you press on it because of the loss of collagen and a related component called elastin. Pull of Gravity As physicist and mathematician Isaac Newton remarked when he described the effects of gravity, “What goes up, most go down.” This is also true for facial tissues and structures.
