I have been trying to grow my lash for some time when I chanced upon this while doing our weekly grocery shopping. It wasn't as cheap as the usual mascaras you find in supermarkets but I decided to give it a try anyway. It is a lovely mascara. My lashes look longer and thicker and best of all, it doesn't smudge even hours of wearing it. I have been looking for a cheaper mascara that won't smudge (I have oily lids and I've tried several cheap mascaras only to end up having that embarrassing black smudge on the lower part of my eye) and this works really well! As for the lengthening effect, I'm not entirely sure how much it has contributed to my lash growth since I have been using two other products for this. The only downside is that the mascara was rather dry when I bought it so i had to put several drops of eye drops into the tube to rehydrate the product.
