Kohl eyeliner makes our eyes more dramatic and intense, but the sad fact is that most of them simply are too creamy to stay in place. That's just the nature of the formula - the creamier, more emollient a product is, the less wear-time you get out of it.
So who wants to wear eyeliner that looks great for only two hours? Not a lot of people, I imagine. But they're still pretty to look at, especially the Revlon Photoready Kajal Intense Eyeliner + Brightener (P525).
The formula is very smooth and creamy, while the finish has a satiny opaqueness to it. Some colors are immediately solid, but I find that the lighter ones need to be layered on to get maximum color pay off. I can live with that.
