Can you use vitamin C with azelaic acid?
Yes — vitamin C and azelaic acid can be used in the same routine without significant conflict.
Why
Ascorbic Acid (Vitamin C) neutralises free radicals, brightens hyperpigmentation, and boosts SPF photoprotection. Azelaic Acid treats acne, rosacea, and post-inflammatory hyperpigmentation with one of the gentlest active profiles available. The two work through different mechanisms with no documented chemistry or irritation conflicts at typical cosmetic concentrations.
How to layer them
Apply the lighter, water-based product first, wait 30-60 seconds for absorption, then the heavier or oil-based product. Standard time-of-day rules apply.
