This is Inglot's Slim Gel Lipstick in shade 55, a brownish red with subtle coppery glitter. I chose it because I love a red lip, and own rather a lot of red lipsticks, but don't have anything anywhere near this shade. It's rich, dramatic, and flattering, and would look rather lovely paired with neutral blush and copper-brown liner. Lovely.
The formula of the Slim Gel Lipstick is strange; until it's warmed up, it's like a stick of wax - hard, unyielding, and draggy when applied to the lips. Once it's warmed up, though, it takes on a much softer, weightless feeling, and is extremely comfortable on the lip, whilst maintaining a texture that grips the lips and doesn't feel slippy. I like it - and I might have to investigate a few of the other colours in the range soon.
Unfortunately, Inglot still haven't sorted their online store for the UK out - so if you'd like to check this out, you'll have to trek to Inglot at the Westfield shopping centre in London, where the lipstick will cost you around £10.
