This isn't a miracle cure but I've given it a 4 because it is so reasonably priced. And there's plenty in the tube so it will last a long while.
It's for all skin types and it recommends daily use. I only use it once or twice a week because I do feel it would irritate my slightly sensitive skin otherwise. It is quite gritty although not drying. It apparently contains "hydrating" Vitamin B5. Also grapefruit and watercress - not sure what they're supposed to do but sounds quite tasty!
It is one of the more gritty exfoliators I have come across so I feel you do have to be careful around those extra-sensitive areas like round the eyes. It does an excellent job getting rid of those little flaky bits.
