For one, Latisse is the only FDA-approved product that has been clinically proven to result in longer, darker, and more lashes. It has been studied extensively for safety and efficacy, and is available by prescription only because patients need to be well-educated on proper application methods in order to guarantee the desired results. Eyelash serums improve the appearance and length of lashes, but they can also irritate sensitive skin. Steer clear of serums with edible ingredients like coconut and olive oil, as they can grow bacteria that can lead to eye infections and styes. And as with any new product, do a swatch test first to see how your skin will react. Dr. Greenfield suggests applying a very thin layer in the corner of the eyelash to see how your skin responds. If you notice irritation, immediately discontinue use and have your dermatologist give the area a look.
