There are several eyeliner formulations: powdered shadow, eye pencil, and liquid or gel liner. Each has its advantages and specific application techniques.
shadow liners are easy to apply, dry or damp, and can be long-lasting if applied correctly. Using shadow liner requires a good eyeliner brush—one that is thin, stiff, and flat, with either a straight or a slightly rounded tip.
eyeliner pencils are easy to apply but may smudge. Pencil liners have a creamy consistency that smears if they are not set with either eyeshadow or face powder.
liquid, ca ke, and gel liners are the most difficult to apply, but with practice, you can achieve incredible results. These liners are extremely long-wearing, very precise, and a good choice for creating dramatic looks.
