Eyelashes of Asians differ from those of Caucasians in morphology and growth characteristics. Ethnic differences also exist for the tolerability profile of prostaglandin analogues.


To evaluate the long-term utility and durability of bimatoprost 0.03% in eyelash augmentation in Asian females.


One cohort received bimatoprost 0.03% for 36 weeks and another for 20 weeks, with the latter cohort followed for 16 weeks after treatment cessation. The primary endpoint was the percent change in eyelash length at week 20. Secondary measures included percent change in eyelash thickness and darkness, physician's Global Eyelash Assessment and patient satisfaction.


At week 20, eyelash length was enhanced in a time-dependent manner, with maximum improvement achieved (19.3%; p < 0.0001). Significant improvements in thickness and darkness were also achieved (22.9%, 6.0%; p < 0.0001). 77.8% of subjects improved by ≥1 grade on Global Eyelash Assessment, with 83.1% satisfied/very satisfied. Improvements were maintained with ongoing treatment to 36 weeks, while these effects were progressively lost with discontinuation.


Bimatoprost 0.03% safely enhanced eyelashes in Asian females, maintained with ongoing treatment. Cessation of treatment was associated with progressive loss of effects.
