Oxidation is defined as the interaction between oxygen molecules and all the different substances they may contact, from metal to living tissue."Free radicals" is a term often used to describe damaged cells that can be problematic.They are "free" because they are missing a critical molecule, which sends them on a rampage to pair with another molecule."These molecules will rob any molecule to quench that need," Blumberg says.Early research on the role of antioxidants in biology focused on their use in preventing the oxidation of unsaturated fats, which is the cause of rancidity.Antioxidant activity could be measured simply by placing the fat in a closed container with oxygen and measuring the rate of oxygen consumption.However, it was the identification of vitamins A, C, and E as antioxidants that revolutionized the field and led to the realization of the importance of antioxidants in the biochemistry of living organisms.The results suggest that the constituents of the various extracts of orange peel, cucumber and aloe vera and their combinations are capable of giving better anti oxidant activity than the commercially available peel off's against the oxidation of skin by free radicals.The face peel off prepared was checked for its efficacy using skin irritation test, the results clearly proved that the herbal face peel off thus prepared is for more active then the commercially available synthetic peel off's.
