Having itchy and parched skin throughout the year can be a sign of ageing, eczema or dermatitis. It can be caused by a number of things like allergies to food or certain chemicals. While you might be resorting to heavy lotions, it is more beneficial to go for oils such as olive, grapeseed, apricot, rosehip and pomegranate, which can percolate your skin easily. Keep a close watch on things that particularly are irritating for your skin, and stay away from them.
