It really depends on what is causing those dark circles. If there is a deficiency of certain minerals or vitamins then you need to address that. If it’s due to an illness or systemic issues, then no topical product is going to help you, you need to address the trigger. If the dark circles are due to pigmentation, then you need to consider something like Lumixyl Revitaleyes or Dermaquest Eye Brite. If the dark circles are due to poor drainage beneath the eyes and you have that “blue, bruised look”, then it’s an entirely different cause and you need to look at something like Neostrata Skin Actives Intensive Eye therapy.
