Zero Gravity has invested a great deal of time and resources in the development of the anti-aging Perfectio™ device. In order to prove the power and effectiveness of all Zero Gravity products, independent clinical studies were conducted, most notably and recently by Princeton Research Division in Princeton, New Jersey.
