The Best Eyelash Growth Serums With 5-Star Reviews on Amazon

Interestingly, lash growth serums were born from a side effect of glaucoma medication: After applying special drops to the eyes, doctors noticed that glaucoma patients were growing longer, fuller lashes. Ingredients like bimatoprost and isopropyl cloprostenate (and other fatty acid compounds) help existing lashes to grow as well as kick-start growth in previously stagnant follicles. But as enticing as the promise of doe-like lashes is, growth serums come with their drawbacks: The key is to look for ophthalmologist- and dermatologist-tested formulas and organic, safe, and natural ingredients, as some formulas may cause irritation, skin pigmentation, or even pigmentation of the iris, meaning green and hazel eyes could potentially turn a brownish tint. 

Curious which formulas work the best with minimal setbacks, we sifted through the mecca of reviews, Amazon, for the most adored lash and brow serums. Take a look at the winning lineup below.
