While I liked the product initially because it does hydrate well something started to happen that I thought might be coincidence.  I started noticing eye bags.  I thought at first maybe I was ingesting too much salt, not hydrated, not getting enough rest, etc.  Eventually I suspected it's the NIA complex and discontinued it.  The bags started disappearing.  A month later I tried it again (new jar this time just in case) to see if this was coincidence.  They began reappearing.  I tried reducing the amount applied, and even just using it only at night.  Only when I switched to another product did the problem clear up for me.
