The UV component of sunlight is well known to cause serious issues for skin and hair like photoaging, erythema, edema, skin thickening, wrinkling, loss of shine and strength of hair, etc, by triggering the generation of ROS, degradation of proteins, peroxidation of lipids. When the levels of important elements like N, P, Ca, and Mg and crude fat or amino acids were estimated in the hair and nails of pet dogs relying on a normal diet, the concentration of all these elements was considerably lower than the dogs consuming a Vitamin E-rich diet. The data suggest that UV exposure has a negative effect on the concentration of these elements, minerals and amino acids however, the effect can be reversed by the supplementation of an antioxidant-rich diet. The present study help to understand how the aging can reduced by using antioxidant in their regular diet and their positive aspects on exoskeleton of mammals
