Garnia Caffeine roll on review: priced £9.99 super drugs. I have always suffered from dark circles and have tried lots of different products to sort it out. I have always been left disappointed. So when I saw this product I thought what have I got to lose ill give it a try! The garnia product is enriched with caffeine and pro-vitamin b5 to refresh and hydrate the eye area. I have been using this for two months now religiously every morning and every evening what a disappointment! The products rolls on nicely with a cooling effect however, it takes a while to dry. I found no change in my dark circles. My eyes did not look any fresher. Don't waste your money on this product! I still have dark circles and puffy eyes my search for the ideal product to combat my dark circles continues .... This will not be a favourite for my beauty box.
