When comparing Latisse to other brands, we need to focus on how our aesthetic services are different, and why it may be a better option for you. Latisse is the only FDA-approved treatment available to help patients grow thicker, longer, and darker eyelashes. Several studies have been completed on Latisse, which creates measurable and real benefits for eyelash growth treatment. Bimatoprost is an active ingredient that provides measurable benefits in the eyelash growth serum. This means your eyelashes will not only just grow longer, but they will become healthier to the point as they will become thicker and darker as well.
