Faces age due to fat loss, skin changes - not gravity
PHILADELPHIA To the surprise of many
people, the loss of fat and sun exposure play a bigger role than gravity in aging the face, according to a study presented today at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2004 conference in Philadelphia. "People make assumpt...
