Hi there, I purchased your product for my daughter for the first time a few months ago after she said she was insecure about her under-eye dark circles. We did not see any results for the few weeks but after about two months I could clearly see a huge amount of improvement, her under-eye dark circles got much lighter. I have continued to purchase more bottles of this product for her so she can eventually fully get rid of her under-eye dark circles. Thank you for this amazing product.
