Sky Organics 

100% Pure Castor Oil for Eyelash/Eyebrow Growth 

Check Price

For consumers who prefer an all-natural product in a generous bottle for a low price, this is a good choice, but it doesn't work for everyone. 

Made of cold pressed, organic castor oil – a product that is known for boosting eyelash/eyebrow growth thanks to its Omega-6 acids. Cruelty and chemical free, and comes with applicators. 

The consistency is thick and oily, making it somewhat difficult to apply. May cause somewhat blurry vision if you get it in your eyes. Not all users saw noticeable results.

Buying guide for best eyelash growth serums

Last Updated August 2019

  

For long, lush lashes, skip the endless hunt for the best lengthening mascara and the hassle of applying false lashes. Eyelash growth serums stimulate the growth of your own lashes, so they grow longer and more voluminous on their own. But not all eyelash growth serums are created equal, which means you might pay a pretty penny and not see the results you want. With so many of these beauty enhancers on the market, how do you find the right eyelash growth serum for your lashes?
