Comparison of the Efficacy and Safety of Using 0.01% Versus 0.03% Bimatoprost for the Treatment of Eyebrow Hypotrichosis: A Randomized, Double-Blind, Split-Face, Comparative Study

This study compared the efficacy and safety of 0.01% versus 0.03% bimatoprost for treating eyebrow hypotrichosis in a randomized, double-blind, split-face clinical trial involving 30 patients. Both concentrations significantly improved eyebrow density and diameter, with no statistically significant differences between them. However, patients showed a significant preference for 0.03% bimatoprost in terms of clinical improvement and satisfaction. The study concluded that both concentrations are effective and safe, with 0.03% bimatoprost being slightly superior, though not statistically significant.
