Actual (reported)This study is a blinded, prospective, single-center, clinical study conducted in Japanese female subjects between the ages of 20-75 years. This design uses skin biopsy samples from environmentally exposed areas and unexposed (control) areas within the same subjects to assess the gene expression profile from three different age groups.
