Starting as close to the base of your lash line, position the brush and wiggle/sweep upward to coat lashes. Built-in double stacked comb will allow you to reach new lengths with your lashes. Comb thru your lashes from the base to the top to build length, and twist the brush to the other side to build length and volume interchangeably. Use the tip of the wand to coat those hard to reach areas in the corners. Don't forget to gently coat your bottom lashes as well, use the tip. Reach new lengths, armed with your specialized lengthening comb.
