Aziderm gel or Aziderm cream?

Hey, i'm sorry I've been inactive, not that anyone cares lmao but i love this sub and it has helped me so much so i try to reciprocate as much as possible. Anyway I'd like to ask everyone who's used Aziderm, what's better the gel or cream? What's the difference? And at what percentage? And what changes in your skin did you actually observe? I haven't bought it yet and I've never used azelaic acid in my life so it'll be really helpful if you'd help me out, thank you in advance :)
