...that your foundation around dark circle ive been told that one should always use a concealer one shade lighter that your foundation around dark eye circles.... is this true and any advise on how to apply foundation and an eye concealer that looks flawless.

Yellow concealer gets rid of dark circles

yes... since dark circles are darker than your regular skin tone you should go for a lighter shade. to make it look flawless, just blend it really good, then top with a powder of your regular shade.... pressed or loose, whichever you prefer.

I recomend getting a little concealer stick strictly for darkcircles. Thestick takes away the darkness then you apply your normal concealer and tada! it's fixed! They actually make sticks strickly for dark circles.

noooooo!!! although it seems logical, it wont be good! you have to match the concealor EXACTLY to your skin tone. thats the whole point of concealor. to give the illusion that your regular skin is even by covering up these circles. if it doesn't completely cover these dark circles, add a heavier application!
the same rule applies to foundation. you need to match the product to your skin tone to make it loor great on you. this might mean that you might need to buy a couple of shades to mix to make it match but its worthit. when you find the product that blends and dissapears into your skin, thats the right one.
