Skin Care Review: sudden change under-eye firming serum

I found that this product had no effect whatsoever. If anything it made underneath your eyes even puffier because it tightens it making it more noticable. Also, did not do anything for my dark circles which the commercial guarantees it will. Very disappointing!! It says to read insert booklet which mine didn't come with so maybe I applied it on wrong. I purchased the trial size product which was hard to get only one drop out of and hard to close back. Next I'm gonna try their dark circle fade cream see if that will be any better. If you purchase this product don't worry they have a money back guarantee-just save your receipt. Ha Ha!!! Hope you have better luck with it than I did. Thank goodness I didn't buy the full size product for eleven bucks, just wasted five dollars!
