Just ordered my second bottle!
I love this serum! After using another product for several years, my eye irritation began to increase. Although BoostLash may not be quite as effective as my former more expensive lash serum, I definitely  see thicker and longer lashes with regular use and no irritation. I suggest starting this product when your lashes are at their best (ie, after using another harsher product).
