Full lips: outline your lips with a pencil thin on the inside of the natural boundary of the mouth. Complete this line (in the upper lip and the bottom) with a soft, matte color.
Very thin upper lip: to conceal a mouth that has too narrow upper lip, ideally, two different shades-always the same pencil to highlight the top to balance it with the one below. The tone of the lower lip should always be softer and less focused.
Thin lips: when the two lips are too thin, it is best to use a thicker eyeliner on the edges and filled with vivid colors.
