I have NYC right now, which isn't really to my liking. I was wondering what your opinion on this was, and which brand of makeup is the best to conceal red blemishes. Also which blush goes on the best and stays on. What's your opinion?

for concealer i would choose Sonia Kachuk becuz its creamy anad glides on to your skin easily and covers blemishes well without the over price

for a blush i like NARS it worth the money

I wont say that one brand is better than the other, all brands have great products. If your are looking to conceal red blemishes you probably want something that is a little bit heavier, so I would suggest a creme based concealer, I don't know what your price range is but I like to use, MAC select cover when I am on set also to take the red out you may want to use a green colored concealer with your concealer. Also one of my favorites, which will give you alot of coverage is Kroylan concealer, this is what I currently have in my kit. http://www.kryolan.com/Camouflage/product_creme.html

Blush I would suggest if you want it to be long wearing, apply a creme blush first then add a powder on top.
