Because of the matt texture it's not one to wear when you have dry lips - you really need to make sure the lips are prepped well and there are no flaky bits otherwise it will definitely show up as it's dry itself (although not drying). The bonus is that it will last an absolute age on your lips. As I sit and type this I have had it on for 3 hours and it doesn't look any different from when I first applied it!
Despite the massive pop of colour, Illamasqua have managed to make such a wearable shade of neon pink - I love it!
