To maximize light reflection on the lips, apply vertically in direction of lips skin tissue. Light will bounce best off the lips when applied this way. Keep gloss slightly within the edge of the lip line to allow room for gloss spread, which inevitably happens when lips rub together.
One of the easiest, long-lasting and impact producing techniques is to fill in lips with a lip pencil first and then and with a clear or very sheer color lip gloss.
Thicker gloss seals in lip-color and lasts longer.
