Azelaic acid probably isn't the first or even second thing that comes to mind when you think of trending skin care ingredients. Who are we kidding? Most of us don't know that it's a part of skincare. Even I, as a self proclaimed skincare fanatic, haven’t been looking too much into this ingredient. Sure, I have heard some great reviews about Ordinary’s Azelaic Acid 10% suspension. However, it never intrigued me enough to spend the money on it.
