RapidLash is a popular brand of eye lash renewal serum that’s applied like eyeliner to your top lashes. It’s supposed to increase the darkness, thickness and length of your lashes within 4 weeks. I used it every night for about 2 weeks and believe it or not, I saw a huge change in my lashes; they seemed longer than ever! However, I read an article about how these formulas in the long-run could result in major eye trauma, which of course scared me to death so I have since stopped using it. But while I did use it, I was pleased with the results.
**UPDATE** I've been informed that contrary to other brands' potential health concerns, RapidLash is paraben-free, with vital proteins and vitamins, including pumpkin seed and licorice extracts that help replenish and fortify lashes. So perhaps, I'll give it another go!
Would you ever try a lash-lengthening formula?
