LATISSE® was studied in a multicenter, randomized, double-masked, vehicle-controlled, parallel-group study (N = 278). Patients applied LATISSE® nightly for 16 weeks.1

  • Grade 1

    Minimal eyelash prominence

  • Grade 2

    Moderate eyelash prominence

  • Grade 3

    Marked eyelash prominence

  • Grade 4

    Very marked eyelash prominence

The primary efficacy end point in the LATISSE® study was an increase in overall eyelash prominence as measured by at least a 1-grade increase on the Global Eyelash Assessment (GEA) scale* from baseline to the end of treatment period (week 16). In the clinical trial, 78% of LATISSE® patients experienced ≥ 1-grade increase vs 18% for vehicle and 33% experienced ≥ 2-grade increase vs 1% for vehicle at week 16.1,2

Helpful tip: Use the GEA scale to help educate patients and manage expectations while they’re away from the office.
