Please do not change the formula. This is my first review EVER on a product and I only felt compelled to do so because my skin absolutely LOVES this stuff. It leaves it just perfectly hydrated, with no greasy film. I actually am lazy with moisturising, but by the speed with which this absorbs it saves me heaps of time in the morning. I am definitely going to be stocking up on this, and I'm just so glad to find a product that works for me. Thanks a bunch Eidon and iHerb!
