Aging is of two types: Chronological aging or Intrinsic aging and Photo aging3. Photo-aging also calledas premature skin aging4is caused by continuous exposure of the skin to solar UV irradiation. It results inseveral skin symptoms, such as leathery texture, mottled pigmentation, and wrinkles. Apart from Intrinsic andphotoaging, so called stochastic aging5connotes cell damage by metabolic processes, free radicals and cosmicirradiation. Hence, reducing oxidative stress has been the major focus of anti-aging research, and the antioxidantsupplements are recommended based on this research. Moreover, these antioxidants are active both topicallyand internally, which means they can be applied in form of creams, gels, or taken as capsules or tablets. Antioxidants are helpful to achieve efficient free radical scavenging, since they relieve one another of free radicalburden. Vitamin E, Vitamin C, lipoic acid, coenzyme Q10, nicotinic acid, and glutathione neutralize freeradicals by different methods, and they complement one another’s efforts.
