Summary of Customer Ratings & Reviews
Skin Tone:: Fair
I bought this when the brand was first launched on Space NK. I had high hopes for this mascara but I was disappointed. On the one and only use, I found it clumped and glued my lashes together the moment I started to apply it. I removed it and started again, having cleaned the brush of product and reapplying with a smaller amount on the brush, but this didn't work either. I'm sticking to Chantecaille mascara which is the only mascara that truly works for me. It's pricey, yes, but at least it's not a waste of money like this was (as you can't return items once open and used, even if they don't perform as advertised).
Best Use: Growth
Not a good texture
The composition of this mascara is great but it is ruined by its texture: it is very thick, difficult to apply evenly and clumps a lot. I will not purchase again.
Best Use: Curling
Skin Tone:: Very Fair
Just go with a drugstore brand instead
The mascara smudges around my eyes throughout the day and barely adds curl or volume. The top of the wand was weighted, which was interested but made using it kind of awkward. I wanted to love this because it looks cute, but it’s a no. I prefer drugstore mascara over this.
Age: Under 30
Best Use: Volumising
Skin Tone:: Fair
I had high hopes for this mascara but it really is awful. Not sure how it even has any good reviews. It is soo clumpy, when you take brush out off tube it’s covered in excess product. It clumps lashes together terribly. I found it flaked during the day and left my under eyes black. Had to return. Would not recommend
I cannot for the life of me understand the amazing reviews that Kosas The Big Clean Mascara has received. If I could I would have given it zero stars as it fulfils absolutely none of the key requirements for a mascara for me - it is thick and clumpy and doesn't apply evenly on the lashes. What is applied doesn't stay on the lashes for long, smudging and leaving panda eyes. Really disappointed.
