Kevyn Aucoin Professional Lash Curler Review: A Heavy-Duty Tool for All Eye Shapes

The Kevyn Aucoin Eyelash Curler, now in its PRO UPDATE version, is a tool that has been making rounds in the makeup community for its sturdy build and claim to work on various eye types. After testing it over several weeks, here are my observations on how it performs in real-world use.

This curler is noticeably heavier than many drugstore alternatives, thanks to its stainless steel construction. The weight gives it a solid feel, but it also means you need to be careful not to apply too much pressure on the first try. The silicone pad that comes with it is replaceable, which is a practical touch—over time, pads wear out and lose their grip, so having a spare included extends the tool’s lifespan.

In terms of function, the curler aims to create a lasting curl that holds through the day. I found that it does a decent job, especially on lashes that are naturally straight or resistant to curling. The curve of the pad matches the natural shape of most eyes, and the handle is designed to give you enough leverage without feeling awkward. However, it’s not a miracle worker—if you have very stubborn, downward-pointing lashes, you may still need to use a heated curler or a waterproof mascara to maintain the curl for more than a few hours.

Key features worth noting:

• Stainless steel body for durability and consistent pressure
• Replaceable lash pad included (additional pads sold separately)
• Designed to fit a range of eye shapes, from deep-set to protruding
• The hinge mechanism is smooth and doesn’t pinch or pull

One limitation is the price point. This curler costs significantly more than a generic drugstore curler, and while the build quality is better, the performance difference may not be dramatic for everyone. If you are someone who rarely curls their lashes or only does so occasionally, a budget option might suffice. Also, the heavier weight can be a drawback for travel or for those with smaller hands—it’s less nimble than lighter, plastic models.

Compared to a standard eyelash curler like those from Revlon or Shu Uemura, the Kevyn Aucoin version feels more premium but not necessarily more effective for all users. Shu Uemura’s curler, for instance, has a slightly flatter curve that some people with almond-shaped eyes prefer, while the Kevyn Aucoin’s curve is more rounded and may work better for rounder or more protruding eyes. It’s a matter of personal anatomy.

Who is this for? It suits makeup enthusiasts who curl their lashes daily and want a tool that won’t warp or loosen over time. It also works well for people with average to larger eye shapes, or those who struggle with curlers that are too narrow. Who might skip it? Casual users, those on a tight budget, or people with very small or hooded eyes may find the curve less accommodating—though it still works, it may not be as precise as a smaller, more targeted curler.

In practice, the curler does enhance the effect of mascara by lifting lashes before application. The curl holds well under a light layer of mascara, but if you apply multiple coats or use a very wet formula, the curl may drop faster. This is true for most curlers, so it’s not a unique flaw. The stainless steel construction also means it’s easy to clean—just wipe with a damp cloth or alcohol pad, and it looks good as new.

Overall, the Kevyn Aucoin PRO UPDATE Eyelash Curler is a well-made tool that delivers on its promise of a lasting curl for many eye types. It’s not revolutionary, but it is reliable. If you value durability and are willing to invest in a quality curler, this is a solid choice. Just keep in mind that no curler can defy gravity forever, and your mileage will vary based on your lash type and daily routine.
