GrandeLASH's MD Lash Enhancing Serum. In order to get maximize your results, you need to use and finish the entire tube in three months, applying it nightly to your lash line nightly. I will admit, I've been struggling to make a habit out of this by missing a night or two weekly but I've still seen amazing results on my lashes. As y'all know, previous to this my lashes were basically nonexistent and I am not exaggerating. I'm trying to make a better habit of using it nightly so get the full results and as you've previously read on my Sephora Rouge haul, I bought the valued tube since I've been loving the results. That one has since sold out but this goes for $65, which isn't too bad if you compare it to lash extensions. Do know, this is not for long lasting lashes due to the hair regrowth cycle. You have to consistently use the product to maintain the length of your lashes but it is still worth it in my opinion.
