I bought this going in with no expectations because I know it's not possible for a product to completely get rid of dark circles. To be honest, I haven't seen any major improvements of my dark circles but it's super moisturizing and doesn't irritate my eyes.
For the people who have said it irritated their eyes, it's probably because you're putting it too close to your eyes. I put this on my orbital and brow bone and I haven't had a problem with irritation. The product will get to your under eye area because we're constantly blinking.
