We don't think so. You can see that they are both the same exact color, the same exact weight, and they move in the same way. The only difference we can see is price-wise. MAC makes their eyelash curler for $14, sold at all department stores that carry MAC, as well as MAC retail stores and MACcosmetics.com. The shu uemura eyelash curler is $19, sold at Sephora and other major department stores. We can't say we believe all the hype over the shu uemura eyelash curler, as it seems as if they are exactly the same, with different labels.
As for usage, both work very well and create a full set of eyelashes. But it's also important to use the right kind of mascara, while you're at it. Check out our future blog posts and see which mascaras are the best, according to MLA. You may be surprised at the full lashes you'll get for your next big night out on the town!
