I have had dark circles and bags under my eyes for years. I've used tons of different
eye creams or various other creams but my dark circles usually stayed.
I bought this on a whim just to see if it does make a difference. It's a bit pricey though and definitely small.
It has a metallic ball and works like a pen. It's super cold too. Getting up for university after a late night of studying or lack of sleep, it definitely opens your eyes up and brightens the area. It's also good if you get up super early for work etc.
So far I've used it for a few days and I definitely notice that my eyes aren't as dark anymore after I use it. Don't know if it's actually making them go away for good, or if it's just temporary for as long as I use it.
It's definitely worth a shot to try it for yourself, especially if you have dark circles or bags or your eyes look tired from a lack of sleep.
