The ETUDE Dr. Mascara Fixer is designed for achieving perfectly set, long-lasting lashes free from smudging throughout the day. This formula functions as an effective eyelash primer, preparing the lashes for mascara application while simultaneously providing a protective care effect. Its primary benefit lies in its ability to lock mascara in place, enhancing wear time and maintaining curl integrity. Use it as a base coat to smooth the lashes or wear it alone for a natural, defined look enhanced by its conditioning properties.
