The fibers in the Physicians Formula Eye Boost Instant Lash Extensions Kit, $14.99, have an almost magnetic quality that holds them right where you want them. You can build thickness and length wherever you need it most, and the result ranges from great mascara to lash extensions. The mascara formula also contains lash-conditioning ingredients to help lashes grow thicker and fuller over time. Eventually, you may not need the fibers at all.

Too Faced Better Than False Lashes Extreme!, $35, is an upgraded version of the Better Than False Lashes, and it completely outshines the original. You apply one coat of mascara, one coat of fibers, and then another coat of mascara, and — miraculously — all the fibers will stay on your lashes instead of drifting all over your face. With this type of system, you have maximum control over just how fiber-y your lashes become, which makes it perfect for anyone looking for that full-on false lashes look.
