Make-up, if done with care can serve as a great way to highlight the lips.

Small Mouth with Small Lips :
These are easily corrected by taking the lip liner pencil outside the natural lip line. Work slowly and steadily to form a perfect shape. Fill in with primer and finally with the lipstick. A highlight of frosting on the upper lip would also create an impression of fullness.

Large Mouth with Full Lips :
Apply liquid foundation makeup to the entire mouth, then outline with a dark shade of lipstick just inside the natural contours of the mouth. Then apply lipstick of a lighter shade carefully and accurately within this outline. Subdued shades work well for this kind of mouth. Use medium toned lip colors and avoid dark browns, plums and electric bright or pale shimmer shades.

Full Upper Lip :
Apply fluid foundation makeup to the upper lip. Outline just inside its natural contour and apply a dark shade of lipstick. Then outline the lower lip just outside its natural contour and emphasize by filling in with a lighter shade of lipstick.

Full Lower Lip :
Outline upper lip just outside its natural contour. Apply a light shade of lipstick and in the center add a touch of lip-gloss. Apply fluid foundation makeup to the lower lip. Outline just inside its natural contour. Then fill in with a darker shade of lipstick, using a lip brush.

Wide Mouth :
Cover the corners of the mouth with foundation makeup or a cover stick. Apply lipstick with a lip brush, stopping a few millimeters before the corners of the mouth are reached.
