First of all, let me say that I absolutely love this packaging. Anything pink with light effects is going to catch my eye, which is probably the main reason I bought this mascara. The tube is so pretty, it would have been impossible for me to resist. Well played, Revlon... well played.
This mascara claims to be lengthening and volumizing, with the description on the back claiming: "The formula with strengthening proteins, amino acids and essential vitamins, revitalizes lashes. The Illusionist Wand drenches lashes for dramatic volume and combs through lashes for clump free length."
A lot of the other online reviews I've read say that this mascara is a hot, clumpy mess, but I actually found it to be quite nice. The formula is a bit on the dry side, but I actually prefer that. The brush is relatively big, but I don't mind that either. I wouldn't say it's overly volumizing, but it definitely adds some length, and I didn't have a problem with clumping. I used 2 coats and didn't have any issues.
Overall, I think this is a good mascara. Good, but not great. I'm not sure if it's meant to grow your lashes (I would assume so based on the fact that the name includes "by Grow Luscious"), but I've only used it a couple of times so I guess time will tell.
