Latisse remains the only FDA-approved eyelash growth treatment, making it the most scientifically validated option on the market. Its active ingredient, bimatoprost, was originally developed for glaucoma before its lash-enhancing effects were clinically observed. Controlled studies show significant increases in lash length, thickness, and darkness with consistent use. The formula works by extending the anagen (growth) phase of the lash cycle and increasing the number of follicles actively producing lashes. Most users notice early improvements within four weeks, with full results typically developing after 16 weeks of nightly application.
While highly effective, Latisse requires a prescription and carries potential side effects, including the possibility of iris darkening in individuals with light-colored eyes. For this reason, it represents a more serious treatment commitment. It is particularly well suited for individuals with hypotrichosis or substantial lash thinning or loss. Careful application along the upper lash line is essential to maximize results and minimize risks.
