Facial aging is caused by both internal and external factors. Internal (or chronological) factors happen over time and are caused by genetics and the natural aging process. External (or environmental) factors are things in the world around you, including sun exposure, smoking, pollution, gravity, facial expressions, and sleep position. All of these factors can contribute to changes in the skin, as well as changes in facial bones.
Facial aging usually begins in your 20s when the firmness of your skin begins to decrease. Wrinkles, blemishes, and sunspots may also start to appear, becoming more pronounced with age. Of course, changes vary from person to person.
The visible effects of facial aging are the progressive changes you see when you look in the mirror – including loss of skin elasticity, sagging, forehead lines, frown lines, crow’s-feet, smile lines, lip lines, marionette lines – the lines framing your mouth – as well as changes to the color and texture of the skin and loss of volume.
