Review (5/5): Great product, be careful if you live in a dry climate.
I've tried a few different eye creams to help deal with the dark circles caused by my chronic insomnia, and this is one of the few that actually seems to work super well. After just two applications I saw a gigantic difference in the size of my dark circles and my eyes looked normal and healthy!
Since one of the main ingredients is a direct Hyaluronic Acid, it's best to use this serum after showering and with some sort of humidifier (if you don't shower at night) and live in a less humid climate, like I do in Los Angeles. I use an essential oil diffuser placed right next to my bed to help me relax and sleep, you can pick one up for about $15 here on amazon.
