Ah, wrinkles. Wrinkles seem to be the symbol for aging, and they are the focus of nearly every slick advertisement for skin care flashing across your television screen. A preoccupation with all types of lines and wrinkles is likely to start in a woman’s late twenties to early thirties, when she sees the first indica­tion that she’s no longer a teenager. In younger women, the presence of wrinkles is usually linked to a premature degener­ation of collagen and elastin from sun damage. In time, how­ever, everyone, including people who were diligent about sun protection, will end up with some wrinkles.
