Having had a dodgy eyelash lift at a salon, my lashes were in need of some TLC. I stumbled across this serum when searching for how to improve the strength of lashes, as they were brittle and short. I am so glad I did! I use it every evening and started seeing results after about 21 days (RapidLash say results after 60 days). The results have just gotten better and better with use. They are now strong, incredibly long (so long I might actually have to stop using it soon!) and more dense. It's rare that they fall out when I'm cleansing or washing my face now, whereas before I would regularly find a few that would fall out each night. I'm so happy I found this, I no longer need to go to a salon for lash lifts or eyelash extensions, nor do I need to buy fake lashes before a night out!
