Garnier Roll-on anti dark circles

I've been using this product for about 2 months. I've got rather bad dark circles under my eyes, which I cover up with heavy concealer every day, but I thought it was time I tried something that could get rid of them and prevent them. I hadn't heard anyone talk about this product, so I bought it on a whim. Garnier also have a roll-on spot treatment which they released the same time as  this product.
I think it's a great product as it claims to get rid and prevent dark circles, and it also works as a concealer. The special ingredient in this product is caffeine, which is supposed reduce dark circles.
I use it every morning, and although it doesn't conceal very much, it does sit under my foundation nicely. The metal roller ball is nice to use in the morning as it's refreshing and wakes my eyes up a little.
I don't know how long you need to use it before you can see the results, but my dark circles haven't increased, but I guess they haven't decreased either. I can definitely see the prevention qualities of this product, but I think I'm going to have to wait a little longer to see my dark circles reduced.
It comes in 4 different shades. It is quite pricey for what it is - £10.49 usually. But I know that it's half price at Boots at the moment, and I'd say it's worth the price of £5.23. But if you really want a deal, I bought mine from home bargains for only £1.99! If you see them in home bargains for that price  you definitely need to pick one up.
