Eyelash growth products with prostaglandins almost all work, but all too often cause side effects, as our readers have reported with, for example, Lilash, such as severe irritation and even hair sprouting in cheeks. Our Five Best picks - Hydropeptide, Folligen, Marini Lash, Dermalash and Keracyte-B - are prostaglandin free and we have tested them and know that they work on lashes and eyebrows.
