These twist up tube comes in a frills free, silver packaging. The shade I have in my possession is No 4, Medium which is in real fact a deep yellowy-beige shade with salmon-peachy undertones to it.
In a total of 7 shades, No 4 is a NC/NW40 in my opinion as I currently wear a MAC Studio Finish Concealer in NC35 and it's considerably lighter than this. The shade of this resembles Bobbi Brown's Correcter in Peach or darker to an extent as to the purpose it serves.
Regarding the finish of this, I am not very fond of it as somewhere in between a cream and a powder. It dries to a semi-matte, powdery finish very much like MAC's Studio Finish Concealer, however because it's not absolutely full coverage, it leaves gaps in the middle and can cling to dry patches under the eye. The coverage of this is light-medium.
Overall, if you have always been in the minority and hated heavy cream-powder concealers such as Laura Mercier's Secret Camouflage and MAC's Studio Finish, then this one will be perfect for you if you have good skin in general and just want to brighten, correct and add light to certain areas of the face minus the hideous grey cast that other concealers deliver.
The shade range is great with salmon, peach and olive undertones. See if you can find yourself a good match as for £13.50, it's surely worth at try just for the shade variations it offers.
