Daily exposure to environmental insults, especially sunlight, leads to formation of reactive oxygen species (ROS) within the skin. ROS are oxidative "bombs", which if not counteracted, will destroy skin components with resultant aging.
Anti-aging serums contain key antioxidant mixtures, specifically formulated to penetrate the skin and neutralize ROS, helping to maintain a youthful skin appearance.
Although the serums have corrective properties, their most important role is protective - to prevent
further skin damage. Anti-aging serums are indicated at any age. It is important to use a product from a reputable company, as antioxidant ingredients, especially vitamin C are notoriously unstable if not properly formulated. Often times the technology for maintaining stability of these ingredients is patent protected, which means that it cannot be replicated by over the counter products.
There are two simple and effective measures that one can take to prevent skin damage and aging: daily morning use of a powerful antioxidant serum and a broad spectrum sunscreen with an SPF of 30.
