Latisse®: is a liquid that stimulates the growth of eyelashes and can be used off-label for eyebrows as well. Latisse® solution is a once-nightly treatment you apply topically to the base of your upper eyelashes, as instructed by your doctor. Then, gradually, the results come in. You may start to see more length in as little as 4 weeks and you should achieve full growth in 16 weeks. It’s not an illusion of growth. It’s real lash growth.
