I know this is one that many find difficult to work with, but I am so satisfied. This has become a staple blush in my makeup bag. Used daily and has hardly shrunk in amount after over half a year!
My tip for application: Draw a line where you want a lot to get a lot of color quickly, blend lightly with a brush, you won't be able to blend it out very much since it's a tint that dries quickly. But use the brush directly on the stick and then blend on the skin, then you get soft edges. By getting the product in the brush before applying to the skin, you don't transfer as much pigment, that's why I like to lay down a small line directly with the stick first. :) Hope this makes sense!
I haven't used this every night, but still with regular use I notice a crazy difference in my lashes. I'm incredibly satisfied, I didn't think I would get such a good result.
