Everyone wants to look young and have healthy looking skin. Anti-aging is a new medical subspecialty in which the aging process can be slowed, suspended and in some cases reversed. It came about as a shift in thinking from aging as an inevitable process to aging as a series of disease processes. Aging processes can be measured, and, as with any disease, there are symptoms and treatments. Anti-aging medicine is a comprehensive practice of preventive medicine that incorporates components of holistic and wellness medicine but goes beyond them with board-certified physicians utilizing specific high-tech testing procedures and medical treatments. Researchers have uncovered a new way in which the aging process is linked to DNA damage--which occurs normally as a result of cell metabolism and environmental influences--and the various ways in which cells repair that damage.
