First thing that bugged me about this product was the fact that because of the water/oil solution, you have to shake it before use… Call me crazy, but I really cannot see the point in that, why should I remember to shake the bottle every single time I use it? Not very convenient in my world. That said, now I can sing its praises! A simple 125ml bottle with light blue water and darker blur oil solution mix together to work like a bomb! I am constantly wearing waterproof mascara, and while I find the best thing to remove it with is baby oil (economical, easy – don’t have to shake it), RO? definitely hit the spot with this little gem. With this, I don’t have to worry about harsh rubbing and wiping (which can hurt your eye area), it is simple and easy to use, and wipes away the most stubborn make-up!
