Is there anything the Azelaic Acid can't be paired with?Updated a month ago

We'd recommend not layering 15% Azelaic Acid Advanced Clarifying Serum at the same time as high-strength direct acids (like strong AHA/BHA exfoliants) to avoid irritating the skin. As with any active, patch test first and build up frequency slowly, especially if you're new to azelaic acid or have reactive skin.
