I was a keen user of this product until I lost my patience after 2 tubes of application every day and night. It might be helpful for people with very less dark circles like the ones you get if you dont sleep enough but for others this would not be an apt choice. For me it just din’t work. But it is afforable and gives u a "tassali" that yeah you are taking care of your eyes but the product sucks. Cheers?
