    My fav!!

    I have been using this mascara for well over a year+ and absolutely LOVE IT.....I have turned so many people onto it when asked for a recommendation -- I've been in the beauty industry for quite some time and have to say this one is impressive and the fact that it's clean is the cherry 🍒 on top!!

    I cannot tell a lie…

    My eyelashes aren’t long or full. But, then I used Big Clean Mascara and they looked just right! I would have given it 5 stars but the brush wand broke. Kudos to Team Kosas, though, for their rapid response and outstanding customer service.

    Loved it so much I had to have another one!

    I fell in love with with mascara and the formula upon purchasing it the charm store. I didn’t try it out for a while as I was working through a couple other brands and I’m so, so sad I waited as long as I did. It’s only been about a month of use and have been hooked since use two! Loved it so much that I don’t want to find myself without it so I got a backup, thank you for being my go to mascara! Volume, length, no clumping, perfect black and separates my lashes like a dream 😊❤️
