Nu Skin Enterprises has incorporated a new anti-aging technology, ageLOC?, into its skin care products; the technology works to slow the effects of enzymatic breakdown and visibly benefit skin texture and tone. According to the company, scientists from Nu Skin and Purdue University worked collaboratively on developing the ageLOC technology, which is designed to inhibit age-related NADH oxidase (arNOX), a free radical generator that increase in activity with age. The enzyme is found on external cell membranes, including in the epidermis, and higher levels of arNOX are associated with increased oxidative damage and breakdown of skin integrity.
