Winter dries out u're skin and so do indoor heaters.. make sure u have sunblock and a heavy moisturiser on at all times =) Body Shop's Vitamin E face cream works really well on dry/parched skin! Don't neglect u're lips..slather them with a good lipbalm too..
PS, olive oil doesn't suit all skins..some breakout with olive oil so a rich vitamin E cream/lotion is the best!
Yes, exfoliation is a great way of preventing the grey winter skin..but switch to a cream scrub with micro-beads for winters.
