Thank you for your enquiry. The question, however, is really “what is causing the dark circles in the first place?” Sometimes a product is not what you need to sort out dark circles. Pin pointing the cause in order to get the correct solution is really important. Dark circles can be caused by: Hormone imbalances; volume loss in the orbit of the eye; thinning of the skin around the eyes (due to excessive weight loss, or with ageing); lack of sleep; kidney problems, to name but a few. So the important thing is to make sure to get the correct diagnosis to be able to get the correct medication, product or treatment to sort out the cause of the problem.
