Well, not gone but unbelievably reduced thanks to an old post where someone recommended Ben Nye Blue Neutraliser, also worth checking makeupalley reviews.
I got mine off ebay (about £10 plus postage, but it is a large pot and you only need a tiny amount, will last me ages) well worth a go if you are plagued like I have been since my teens with dark circles. I have over the years tried countless products, which all seem to give me grey rings!
That's it really just wanted to share, I keep looking in different lights to see it again! I have put it under my foundation by the way.
