The crystals don't feel harsh on my skin at all!
On days I feel like my face is a little more oily I use more powder and on other days I use a little less. I love that I can do this as my face has different needs on different days and I don't have to use a different product.
I love this set because it is amazing on my skin and comes in a cool little bag, which i can pack in my suitcase to identify exactly where it is. So good for when you are constantly travelling and on the go. My skin gets dehydrated so much from flying and i need a good routine to hydrate thoroughly.
