Azelaic Acid for Rosacea

By Dr Magnus Lynch MA(Cantab) DPhil(Oxon) MRCS FRCP

Azelaic acid is a an effective topical treatment for rosacea and can reduce redness, inflammation, and bumps. Unlike many other treatments it is considered safe during pregnancy.

Is azelaic acid worth trying for rosacea?

Yes. Azelaic acid is effective for many patients with mild to moderate rosacea. It works by calming inflammation and helping normalise skin cell turnover. Many patients notice improvement in redness and pustules after 6–8 weeks of consistent use.

What strength of azelaic acid should I use?

Azelaic acid comes in two main strengths for rosacea:

15% gel – generally well tolerated and often the starting choice.
20% cream – slightly stronger, good for persistent or thicker skin areas.

Start with once-daily application on a small area to check that it does not irritate your skin. You can apply to a wider area after this.

How can I stop azelaic acid from burning or itching?

Burning or itching is common initially but usually improves with consistent use. Tips to reduce irritation:

Moisturise first: Apply a gentle, water-based moisturiser such as Cetaphil or Cerave 5–10 minutes before azelaic acid.
Use a small quantity: A pea-sized amount for the entire face is usually enough.
Avoid broken skin: Do not apply to areas of active inflammation or open wounds.

How long until I see results?

Improvement is usually seen after 6–8 weeks, but some patients notice gradual benefits earlier.

I do not have financial ties to any brands, but patients often find these helpful:

Finacea 15% gel
Skinoren 20% cream

Both are suitable for rosacea and generally well tolerated when introduced gradually.

Another good option is topical ivermectin (e.g. Soolantra). I generally find this to be the most effective treatment for inflammatory rosacea. It can also be combined with azelaic acid.
