i have chronically dry skin, like, sahara dessert dry, and can never find a good strong moisturiser. bought this on a whim 2 days ago (sale from £35 to £9) and WOOOOW!!! for the first time ever my skin is baby soft and my acne has cleared up a bit, which is amazing for just 2 days. if you're hesitant to buy it i'd advise to just go ahead, unless you're allergic to shellfish or dustmites!
