What is a foot file and how often should I use one?

Major fan of scented candles, Make Up brushes and Highlighter. I’m always on the hunt for those Holy Grail products and my dressing table is covered in more beauty products than I like to admit. As an adopted Northerner originally from Brighton, I spend most my days wondering what all this rain is about. My hair isn’t grateful for the move. Currently loving: NIOD Photography Fluid
