Fuller-looking, longer-looking lashes and brows in as little as four weeks… are you up for the challenge? Rapid Lash claims to be “infused with a blend of paraben and fragrance-free potent polypeptides, vitamins, minerals, and botanicals that nourish your lashes and brows.” This eyelash enhancement serum also boasts of an easy, safe, cruelty-free formula and a price that’s rarely found in its product range.

Official Site:


  • Highly affordable price
  • Addresses eyebrow health as well
  • Interactive video and site for easier data search
  • Paraben- and fragrance-free


  • Lacks clinical data or findings to back its claims
  • Poor quality of applicator
  • Underwhelming results in the 2nd to 3rd week mark

Overall Rating

Rapid Lash is perhaps among the most well-packaged and well-positioned eyelash enhancement serums on the market today. Its highly affordable price and “natural” formula make it a force to reckon with, but the end question is: does it live up to expectations? It promises great results in less than four weeks, but although we love the noticeably improving shine, we are still quite disappointed with the sparse lash growth. Potential and long-time customers of Rapid Lash would also truly appreciate clinical findings and tangible targets (both on lashes and brows), so it would be best to have them handy on the site. It’s also wonderful that Rapid Lash caters to a tight budget – we just hope that the length of time needed for lash therapy will not defeat this purpose of saving money.

How to Apply

  1. Wash your hands and face.
  2. Apply Rapid Lash once a day to lashes (like you would an eyeliner) and brows.
