I'm not a makeup artist, so it feel odd at first to comment on tools like this, but funny thing is I learned lash curlers the same way I learn systems by paying attention to fit. The right curler usually matches your eye curve without pinching, so it should sit comfortably at the lash line without tugging skin. I curl before mascara because lashes are more flexible that way, and I replace a curler every year or sooner if the pad hardens. Hourglass Lash Curler feels gentle and controlled, which makes it tug free even on short lashes. It presses evenly without that sharp snap that scares people. Surratt Relevee Lash Curler works better for round or larger eyes because the curve feels wider and more forgiving. It were abit easier to reach corner lashes without awkward angles.
