What are the Yellow and Green Concealer Correctors used for?

What are these things used for EXACTLY anyway?

I've been asking that question to myself lately as I have been questioning if the green one was worth buying.

Basically, these are corrector concealers. You use these before you use your regular concealer and/or foundation. They say these are for redness and other discolorations. But what discolorations are supposed to be used for exactly?

Good thing there's this nifty function in photoshop where you can invert the color to see it's exact opposite.  

Lo' and behold the true shades that they are meant to cancel out:

Looks like Yellow cancels the Bluer purple hues and green cancels out the reddish purple hues. G

This means Yellow can brighten the skin with less power over redness. It will just remove the dark bluish hues from your complexion. Good for freckles and blemishes. This will also do great for the undereye as it will remove darkness and will not add blue that can darken it more.

And the Green will be better at removing the pulplish shades. Good for reddish discolorations such as pimples and red blemishes as well as reddish bruises.

So how does it look when canceled?

Ofcourse, this varies too as your skintone will also be a factor. You'd probably get something near white when done correctly. That's when you'll cover it with your skintone's shade of the cover face you have. Others like to set it with powder first. 

Goodluck!!! ♥
