Technically, any curler you use improperly—say, by clamping it down too close to the base of your lashes or the corners of your eye—can potentially nip your skin. “No curler with two surfaces coming together in opposition is pinch-free,” said Stephanie Kellar, inventor of the now-discontinued Lashpro curler. Tweezerman has an extensive line of affordably priced curlers that work just as well as the pricier ones, according to most internet reviews. On this one, the eyelash pad — the rounded crescent which helps shape lashes — is silicon rather than the more common rubber, making it a good option if you have sensitive eyes. However on stubborn eyelashes, Hou found that this one didn’t hold a curl for as long as others.
