This mascara is honestly the worst tube of mascara that I've ever bought. It is also the most expensive. It did not thicken lashes at all. When I went outside into the sun it began to run in less than a minute. I would not recommend this product to anyone.

I didn't know this mascara, till now. It's great to use and it lasts all night long!!

My lashes are naturally long, so I'm always looking for something that just thickens. This is great if you want your lashes to look longer, but doesn't really thicken them. It does have a great texture and doesn't leave your lashes "stiff" or clumpy.

I'm all about thick lashes and I was excited to purchase this product.
I bought the water-proof kind since I live near the ocean. I'm not sure if that is the reason, but this mascara does NOT thicken my lashes. If anything, it separates them and makes them look stringy (not the best description but that's all I can think of right now.).
If you're looking for lash "doubling", I'd keep looking.
