The arNOX Enzyme: Implications for Intrinsic Aging
By: Helen Knaggs, PhD, Nu Skin Enterprises
This article describes a membrane-bound enzyme found in skin whose activity increases as biological age increases. The enzyme, located on the external surface of fibroblasts and keratinocytes, generates free radicals. The present work identifies the biological mechanism of the enzyme and its relationship to the appearance of aging in skin.
