A recent medical journal report may shed some light on what causes skin wrinkles. According to research, the change in bone structure that is an unavoidable aspect of aging may cause sagging skin on the face, reports CNN.

Plastic surgeons compared the bones of 60 people of various ages. They found that as one grows older, bones begin to shrink, causing skin to become less taut.

Doctors were able to pinpoint specific structural changes that may occur in one's facial bones. Eye sockets are likely to become wider and longer as one grows older, while the bones that form the nose, brow and upper jaw were likely to shrink.

The lower jaw is also likely to decrease in size, which could lesson one's chin pronouncement. According to the news source, the mandible provides the structure of the lower face.
Surgeons also believe that diminished brow bones could contribute to wrinkles around the eyes known as crow's feet.

Older adults who are considering undergoing plastic surgery in order to counteract signs of aging should research their physician's credentials, according to the American Society for Aesthetic Plastic Surgery.
