Ok so I have dark circles under my eyes, I sleep well, eat well, not overweight, I don’t smoke, I drink occasionally but not often. I think its hereditary.
So my mom told me to use her anti-age eye cream every night which is rich in antioxidants, but it seems to be darkening the skin under my eyes, how can this happen?

don’t know why it would darken the circles under your eyes, but I can tell you from what you wrote that the solution to your problem is to drink more water.
