Results of a breakthrough study recently presented  at the 25th International Federation of Societies of Cosmetic Chemists Congress (IFSCC) in Barcelona revealed a correlation between levels of a newly identified age-related enzyme, arNOX, and a person’s appearance. The study, conducted at Stanford University, demonstrated that women with higher activity levels of arNOX appeared an average of seven years older than their chronological age, while women with decreased activity levels of the enzyme appeared to be seven years younger than their actual age, on average.
