This is the fixer I use!

It is none other than the Etude Dr. Mascara Fixer for Perfect Lash. The name is seriously ridiculously long.

As expected from a mascara fixer, the hold and longevity were amazing! Even on hot and humid days like these, my mascaras didn't droop and stayed firmly fixed all day long, so I am very satisfied.

You must control the amount and smooth out the hair texture when applying! Also, since it hardens after application, you need to fill in the gaps thoroughly so it doesn't look patchy. That's it.
