Cartoonjane & Havingkittens I think the one in the tube is 'Disappear' - I quite like it too but last time I went to the EL counter they had sold out so I bought the Double Wear concealer (which comes in a transparent lipgloss style tube with a gold lid and a dovesfoot wand) and I think I prefer it - it's a very liquid texture (less creamy) and sets quickly then becomes pretty firmly fixed.
I believe Laura Mercier Secret Camouflage is very good also, but never tried it myself.
