Buffing not only provides an attractive lustre but also stimulates blood circulation at the base of the nail which encourages healthy growth. The Nail Buffer Kit contains two pads: the grey pad has a slightly abrasive surface to even out ridges and other irregularities; the pink pad is for polishing. Directions for Use: To be used on bare and dry nails: To even out irregularities, gently draw the grey buffer across the nail - in one direction only - avoiding the nail tips (once a month is sufficient), without heating the nail. Shine the nail with the pink polisher, using long, energetic, back and forth movements.
