Prepare the new growth area (visible at both cuticle and smile line) and remove the shine from the entire nail surface. Draw the new smile line with a pencil behind the natural smile line, closer to the cuticle.

Using NSI’s French Fill Bit (either the two-or three-week bit), score a line across the pencil mark, holding the drill at a 45° angle. Then, holding the drill parallel to the nail (as shown), grind out the area to be backfilled. Remove the top layer of the remaining free edge and dust off the filings. Wipe with acetone to remove pencil marks. Wet the entire backfill area with Pink Balancing Liquid.
