A post on the Makeup Addiction subreddit says lash curlers arent a one-size-fits-all sitch. NYC makeup artist Suzy Gerstein confirmed this, but instead of using the complex facial measurements in the post to find the right curler, she shares easy guidelines here.

So who needs which kind of curler?

Big eyes need one with a large arc such as Surratt Beauty Relevee Lash Curler. Smaller eyes can try a half curler, like M.A.C Half Lash Curler; use it in two sections to fully cover all your lashes.

Is there a technique that works for all eyes?

Yes! Angle the tool toward your nose and lightly press lashes three times: by the root, at the middle, and close to the end, for a gradual arc. (If you have short lashes, one crimp will do.)

My lashes wont stay lifted after I curl them—is there anything that will help?

Post-mascara, try a heated wand, such as Lash Star Beauty Heated Lash Styler. Run it through a few times to solidly set that arc.
