This mascara is a must for oily skinned girls. It just doesn't budge: no smearing, no smudging, and in my experience, no flaking (at least not a newer tube: past 4 - 6 weeks it's not so great but I'll ger to that later.) It's the ONLY tubing mascara I can wear on my bottom lashes and know that, come the end of the day, it'll be exactly as I applied it first-thing. I can't think of another mascara I've tried that does this that's still for sale: Clinique's now-discontinued Flutter-to-Full mascara was my former HG and the only other product I could rely on. I'd be lying if I said I wasn't upset about that loss for months (I'm still not over it. Lol)
I've noticed this is a bit of a 'love it or hate it' product. If you need to wear a tubing mascara, then this ticks a lot of boxes, but if you don't, then it won't be nearly as good, so it's important to know what you're getting. The application process is a bit of a learning curve. Product from a fresh tube will go on really wet and has a tendency to clump if you let it dry between coats. It's at its best 1 - 2 weeks after opening, but as I said before, it doesn't last long, or at least not as long as I'd want for the £13 price point. I'm willing to compromise, though, because I think that's mostly down to the formula and I'll take a shorter tube life over panda eyes any day.
It comes in black or black brown which is nice though I've accidentally picked up the wrong shade before and couldn't tell the difference once it was on. It took me 2 weeks to notice I'd even bought the wrong shade. The brush is quite small with small, plastic bristles, perfect for my sensitive eyes. I prefer smaller brushes for application as I think they coat more lashes. It comes off with warm water in gummy tubes which is quite alarming and can look like you're losing lashes: in reality, it's just to do with the way the product coats and sets on lashes and these tubes don't irritate my eyes on removal.
Again, this is great if you need a tubing mascara, but if not, there are products that will give you better volume etc. I'm lucky enough to have long lashes, and this lengthens more than it volumizes and doesn't hold a curl all that well. My priority is no panda eyes, so if that's a priority for you as well, this is as good as it gets for the price point.
