A HISTORY OF FIRSTS
THE ORIGINS OF REVERSE AGING:

MORE THAN TWENTY YEARS OF RESEARCH

A history of firsts - Dior Science

For over 20 years, Dior Science researchers have been interested in some of the Hallmarks of aging. As a result, they have made worldwide discoveries, often through fruitful collaborations, leading them to enter the field of Reverse Aging.
