I recommend a mascara remover.

I highly recommend the Etude one!! It's the One Shot Clean mascara remover, and I'm really satisfied with it because it has great cleansing power and isn't irritating, so I can remove it comfortably just like rinsing with water. The price is reasonable, the ingredients are gentle, and it doesn't have a scent, so I've been using only this for years with great satisfaction! I recommend this to anyone who has run out of mascara remover and is looking to buy a new one.
