Can you layer The Ordinary Azelaic Acid Suspension 10% and The Ordinary Rosehip Seed Oil?

They have a website that tells you what you cannot use together. You should check it out. If you don't see it, I think it is best for you to reach out to them. They have free skincare consultations via video chat with professionals.

You can layer them no problem ☺️ also, i would out azelaic first 💕

The oil should go as the last step of your routine.

yes! azelaic acid can go with actually anything

I use both of these, Azealaic first then rose hip ❤️
