It literally pills with every product I've tried, it's impossible to use. It has a very gummy texture that never gets absorbed into the skin, it only stays on top like a silicon-y film that will ruin any other product you combine it with, and also avoiding the formula to penetrate and actually do some work into your skin. So despite it's relatively high concentration of Azelaic Acid, it takes way more time to show results than similar products (if you're still using it by then).

If you're interested on an alternative: "AZID" from "Theramid" is a great serum, with a 15% of Azelaic Acid that in my experience, can work wonders.
