If you like longer, thicker eyelashes, this one is a no brainer as long as you can afford it. Latisse is a prescription solution that you put on the base of your upper eyelashes like eyeliner. Unlike mascaras that just create an optical illusion of thicker eyelashes, Latisse is the real deal and actually grows thicker and longer lashes. You can get a prescription from your dermatologist. The recommended dose is one drop per eyelid brushed on the base of your upper lashes once daily. One cost-saving tip: once you get the desired results, I recommend decreasing the frequency of application to twice weekly, and you can usually get by with one drop shared between both eyes for maintenance.
