What it is
Azelaic acid is a naturally occurring dicarboxylic acid with anti-inflammatory and anti-redness properties. It carries high-quality (Grade A) evidence for papulopustular rosacea and also reduces the redness that surrounds active bumps — though it does not treat background flushing or visible vessels. Unlike many actives, it is generally well tolerated by reactive skin.
How to use it
- Start with a 10% OTC formula (or 15% prescription, e.g. Finacea) every other morning.
- Build to once or twice daily over two weeks as tolerance allows.
- Pair with a ceramide moisturiser and mineral SPF — avoid layering it with benzoyl peroxide, which can be too irritating for reactive skin.
- Give it 8–12 weeks for full effect; rosacea actives are slow but steady.
