I am an essence cosmetic fan and i try all their products. I love the the effect of this mascara, it gave my lashes drama and curl and volume. I just found that the product does get a bit lumpy and clumpy in the bottle towards the 1/4 mark. This is usually a sign that I need to buy a new one, but it is a lot of wastage, if you keep tossing 1/4 bottle out. I tried adding eye drops to loosen it up but that is temporary. The product clumps right back up after a week.
