Be careful with the Touche Eclat if you have sensitive skin, I had a really bad reaction to it which lasted a couple of weeks, and apparently this is very common with TE. Definitely do a patch test first.
Back to your original question, a while back a magazine I read got members of the public to test products and give their opinion on them. One of the products was creams for reducing undereye circles (not puffiness or bags).
The one that came out top was Korres Eyebright cream, out of the 100 that tested it only 1 said they did not notice a difference in the dark circles!
