The only thing worse than a zombie apocalypse is looking like you just escaped from one. And if you're naturally shadowed or perpetually sleep-deprived, then you might want to be armed with a good concealer.
Eye shadow can add depth and dimension to one's eyes, complement the eye color, make one's eyes appear larger, or simply draw attention to the eyes. Eye shadow comes in many different colors and textures. It is usually made from a powder and mica, but can also be found in liquid, pencil, cream or mousse form.
Pencil eyeliner is easy to apply, but sometimes doesn't spread as smoothly or thickly as gel or liquid liners.
Gel liners are matte and glide on easily. They sometimes come in a little pot with a brush.
Liquid liners are used for their precision, and usually come in a tube with a small brush, or "pen-style" with a brush tip.
