* ROS is the oxygen-based family of free radicals that attacks lipids in cell walls, as well as the skin’s barrier, energy-producing mitochondria in cells and reproductive DNA. These reactions lead not only to inflammation and aging in epidermal and dermal tissues, but some researchers believe that UVA-generated ROS also are the link to the almost threefold rise in melanoma throughout the past 20 years, even though sunscreen use is on the increase worldwide.
