Wrinkles

Wrinkles  are lines or creases that develop on the skin as a result of the natural  aging process. They commonly appear around the eyes, mouth, and forehead and  are more prominent with age. Contributing factors include repetitive facial  expressions, thinning skin, and loss of elasticity and collagen.

As we age, the skin produces less oil and loses moisture, which can  contribute to a drier and more fragile surface. The decrease in fat in the  deeper layers of skin also causes it to sag and form more pronounced lines  and creases. Wrinkles can vary in depth and are often categorized as either  dynamic (caused by muscle movement) or static (visible even at rest).
