I have dark circles under my eyes.. can i use fae out cream under my eyes?

Yes: Be careful not to get in your eye.

You could, but..: I don't know any that work well. Some people inherit dark circles to some degree, but other times it's from anemia or environmental factors such as lack of sleep or allergies of the eye/nasal sinus area. Try getting better sleep and addressing whatever allergies you may have, both in your eyes and in your sinuses, and get a medical checkup if you haven't had one recently.
