I'm having trouble with mascara drying up really fast also. Doesn't seem to matter what brand or where it's purchased.
Tarte Lights, Camera Lashes I like, but the last few tubes are drying out super fast. It costs too much to replace every 2 weeks.
Feel like cosmetic companies are taking advantage of customers.
Tarte Lights, Camera Lashes looks like the company spends most of the money on the purple exterior fancy tube, instead of putting more mascara in the tube.
