This is sorta funny. I just ran upstairs to look at MY eyelash curler that I LOVE..... It's the SAME one! She Uemura! I've tried MANY and this is the one for me!
You may have already tried this, but I blast mine with the blow dryer to warm it up (just a little... don't want to burn yourself!!) and it helps create a stronger and longer lasting curl. I echo the Shu Eumura recc though :)
Put a lighter to it! Just for a second or two, curl, and repeat. (I used to use a blow dryer, but it heats the sides too much for me- with the lighter you can heat just part that curls) I’ve been doing this for the last 15 years and I can use any curler with this technique. Everyone I showed has hopped on the train. It makes the curl last a long time, and you don’t have to splurge for a fancy curler.
