I'm considering getting it, so I wanna ask which one would match best with 1N/2N? The first one looks too white, second one looks kinda pinkish (and I don't need anymore of that on my face lol), so I'm thinking the third one. I think it was called neutral fair or something like that? Anyone?

I recommend sampling first... I use Lite, and I find it to have a peachy-pink undertone, and it would probably be a hair light for you -- it's about as pale as my Alabaster/1W foundation mix (just different undertones -- but that's ok because I use it under my eyes and the peachy-pink tones help cancel the dark circles).

I would suggest sampling Neutral Fair, Neutral Lite, and Light Beige unless someone else stops by and can give you a more precise answer -- I think these are all fairly light shades that may work for you.

Also, what do you want to conceal? If it's for undereyes, a lot of gals also love the Pink concealor so you might try sampling that too

Redness around my nose and mouth. I have the powder concealer but I think cream would maybe work better. Also, I have a green one but it always comes on too green! So I wanna try one that could cover redness good that's not green. And I should try the pink one for my undereyes if it's that good. Haha. I gotta get samples for sure!
Btw I mix 1N with 2N but mostly the latter if that helps.
