Although wrinkles can signify wisdom or at least some level of maturity, no question newly born infants also have wrinkles. The real concern that most of us have is that certain types of wrinkling are associated with the aging process. In our current "pop" culture, people do not view aging positively. Generally, the treatment of normal skin aging that does not result in a functional abnormality is termed "cosmetic."
There are several medical (topical medicines and creams) and many invasive techniques available for ameliorating wrinkled skin. They are all effective to the degree that (1) they change the nature of aging collagen, (2) they stretch the skin, (3) fill in the depressions in the skin, or (4) they paralyze muscles that cause the skin to crease. They include both medical and surgical methods, Laser skin resurfacing, Fillers, Facelift, and more.
