I am always in the mood for a good mascara, especially one that will lengthen, add volume, and not clump my lashes together. For about 11+ months, I have been using the Revlon Grow Luscious Mascara in blackest black, so I think I have a pretty good insight on the performance of the product.
Adds Volume: Yes, I believe my lashes looked fuller and thicker.
Improve the appearance of lashes: Yes. I believe my lashes look more noticeable then without the product. Cannot attest to whether it helps my lashes grow. I did not notice a difference in growth.
Has an oversized lash brush: Yes, although I find that sometimes the brush is too large.
Overall: The mascara does add volume and lengthens, separates does not clump or melt away during the course of the day. I would definitely (and have) repurchase and recommend.
