Oxidative stress is a phenomenon caused by an imbalance between production and accumulation of oxygen reactive species (ROS) in cells and tissues and the ability of a biological system to detoxify these reactive products. ROS can play, and in fact they do it, several physiological roles (i.e., cell signaling), and they are normally generated as by-products of oxygen metabolism; despite this, environmental stressors (i.e., UV, ionizing radiations, pollutants, and heavy metals) and xenobiotics (i.e., antiblastic drugs) contribute to greatly increase ROS production, therefore causing the imbalance that leads to cell and tissue damage (oxidative stress). Several antioxidants have been explored in recent years for their actual or supposed beneficial effect against oxidative stress, such as vitamin E, flavonoids, and polyphenols.
Antioxidants can protect from free radicals and helps in case of foods intake deficiency or increased amount of nutrients. Useful to protect the skin from UV-induced oxidative damage.Helps protect against the free radicals action due to UV exposure or severe ambiance conditionsProtection against the free radicals action due to stress, alcoholics,UV exposure or polluted ambiance conditions.
