Yes. According to data from the FDA, 79 percent of people who use Latisse experience at least one grade increase in Global Eyelash Assessment (GEA) score after using the medication for 20 weeks or longer.
By week 16, people who use Latisse daily experience a 25 percent mean increase in the length of their eyelashes. The increase in thickness is even more pronounced — by week 16, the mean eyelash thickness of people who use Latisse increases by 106 percent.
Latisse also causes a slight increase in the darkness of the eyelashes, although this isn’t quite as intense as its effect on eyelash length and thickness.
