Mascara fixer is a must.

This is my absolute favorite mascara fixer. It's the Dr. Mascara Fixer from Etude House, and I think I've been using it for almost 10 years now, haha. No matter how good a mascara is, it's bound to droop over time, right? However, using this fixer, my eyelashes stay fixed all day long and don't droop. It's the best.
