At New York City’s Sweet Lily Natural Nail Spa, seasonal pedicures look and smell more culinary than cosmetic:  Past hits have included Vanilla Latte and Apple Cider.  For an instant pick me up at home, take a page from this summer’s treat, Lemon Aid:  Dip half a lemon in ¼ cup of granulated sugar that’s been mixed with two drops of lemon oil, then massage the lemon over your feet in a circular motion.  The mixture of sugar and citric acid will help exfoliate your rough patches (and it will feel great too).
