Overview: Lancôme’s mascara is great for anyone looking for a more dramatic eye makeup look. It adds such amazing volume to your lashes that it’ll almost look like you’re wearing expensive falsies. Since it’s meant to last for 24 hours, this mascara is waterproof and smudge-proof. Looking for a mascara that won’t irritate your eyes? The following are some of the best hypoallergenic mascara options for people with sensitive eyes. The common consensus: Wearers love the buildable feature without the clumps (or worst lashes lumping together). The vitamin-enriched formula makes it easy to do one coat for a natural look, or three coats for a night out without ever getting spidery. The mascara's hourglass-shaped brush certainly helps, making it easy to define and separate your lashes to the fullest.
