I've never looked at this, but whenver I get matched, the lady's at the counter give me either one shade lighter or darker depending on what im trying to cover up. I will check out my concealers when I get home. Im curious now:kopfkratz:
I actually need the same advice cuz I use NC37 Foundation and I hate my undereye NC35 concealer! I tried the NW and I liked it better but I couldn't get myself to buy it!!
