Essence is sadly not available in the UK, but thanks to the efforts of a fellow polish addict in Switzerland, I now have my glittery tips on a number of Essence polishes - including Lil@c, shown here.
Lil@c comes with a long, thin, quite flexible brush which holds just the right amount of polish (with a scrape) and is soft enough to splay out a little on the nail, which makes a tidy cuticle line much easier to achieve. It's a gorgeous purple colour (all these pictures show it slightly more blue than in real life, as purples are hard to capture accurately) with a green duochrome sheen, is very pigmented - opaque in two coats, though the duochrome effect is more obvious with three - and dries reasonably fast to a fairly glossy shine (though it could be improved with topcoat).
(Excuse the ding in the index nail. I was in a hurry to catch the daylight and didn't wait for it to dry properly!)
Wear is very good, after two days I've yet to see much in the way of tip wear despite lots of typing.
The green duochrome sheen is actually pretty muted compared to some other duochromes I've seen, even compared to the other duochromes in the same collection... with two coats and indoors light I couldn't see it at all, and it wasn't til I added another coat that I noticed it (and even then it's only really in certain light, when you hold your hand at a funny angle and squint a bit). The effect is much clearer in daylight.
