Love the innovation!
As a marine biologist, I love the idea of using marine sponge spicules in skincare - what a cool idea to try to get products to penetrate deeper. I have been using this product almost every night and have found it to be just the right level of pricklyness. I don't find it painful, and it hasn't caused irritation. I think it is helping with my large pores. Looking forward to trying the different colour versions and maybe even the 700 level...
