Love my MUFE HD Foundation - I use #115 when I'm fair and #118 when I'm tan (I have a very hard time finding foundation colours when I'm fair, I am neutral with both yellow and pink undertones arrgh! 115 is PERFECT for me. MAC always looks too yellow or too pink).
I love the medium buildable coverage, the way it sinks into your skin invisibly and how fantastic it looks in pictures.
I do have pretty oily skin, so I put MAC Matte Gel underneath and then set it with whatever photo-finish setting powder I have on hand and it lasts fine.
The best bit? It doesn't make lines appear worse (it actually improves them by moisturising) and any breakouts you've had - especially if they're dry and healing, it moisturises them too and COVERS. Most foundations I've tried make flaky bits and spots look worse by going too cakey over the top. Not MUFE HD.
I do also like the bottle and pump (thank god for pumps!). Usually one to two will do my whole face, maybe 3 on a bad skin day. A few people have said how the plastic bottle appears cheap - I think it's a godsend - have you ever dropped a glass foundation bottle? Not pretty AND expensive. Plastic is much better. And the pump gives you a little at a time so not too much wastage happens.
Seriously HG.
