Re: Concealer
I couldn’t agree more…I had trouble finding the right shade, because I just in the middle medium, with very little yellow and red, but thankfully after couple of trips to the store, I found the right shade 
Their concealer is super light and airy, I wear it by itself the days I don’t feel for a made-up looking face
If you haven’t already, try the their original foundation too - again a little tricky to find the right shade but its gives awesome even coverage (I call it my grocery run foundation)
