I ordered this on a whim.  I normally use Face Blur, but have been looking for something that provides just a bit more coverage for the days when I feel like trying to hide my freckles more than usual.  Little bit of background info on my skin.  I'm super pale, have freckles and dry skin.  I'm in my 30's and am a definite skincare junkie. 

I ordered #21, since it was the lighter of the two.  As you can see in the picture, I did receive the 21, but the color looks more like #23 does.  It does cover fairly well and goes on very smoothly.  It does seem to have a slight pore hiding effect, which is a bonus.  Had it been lighter, I think I would have really liked this, which is why I'm still giving it 4 stars.  Unfortunately, it is a bit too dark for my skin tone.  Because of that, this review also does not reflect whether it is long lasting or if it tends to settle at any point.  I'd really like to see this offered in more colors at some point.  It could be a good contender if the color matches your skin tone.
