Quick Answer
Azelaic Acid Suspension 10% is a multi-tasking treatment that calms redness, evens skin tone, and helps clear blemishes — gently enough for daily use, unlike most acne actives. It has a thicker, slightly gritty texture that takes some getting used to, but it’s one of the few actives suitable for sensitive and rosacea-prone skin too.
What Is The Ordinary Azelaic Acid Suspension 10%?
Azelaic acid is a naturally occurring acid found in grains like barley and wheat, and it’s used in prescription form (often at 15-20%) to treat rosacea and acne. The Ordinary’s 10% suspension brings a meaningful dose of the same ingredient into an over-the-counter product, formulated as a thick, matte cream-gel.
It works on multiple fronts at once: mild exfoliation, calming inflammation, brightening discoloration, and reducing the bacteria linked to breakouts — which is unusual for a single ingredient.
Why We Recommend It
Azelaic acid has one of the gentlest safety profiles of any serious acne-and-redness ingredient, which is why dermatologists prescribe it for rosacea patients who can’t tolerate retinoids or benzoyl peroxide. Getting a 10% concentration at this price point is genuinely rare — most azelaic acid products at comparable strength cost several times more.
It’s also one of the only actives on this list that can typically be used both morning and night without the sun-sensitivity concerns that come with AHAs and retinol, making it a low-friction addition to almost any routine.
Pros
- Calms redness and inflammation gently enough for rosacea-prone or sensitive skin
- Evens out post-acne discoloration and overall skin tone with consistent use
- Can be used daily, morning and night, unlike most acne actives
- Doesn’t significantly increase sun sensitivity
- Rare to find 10% azelaic acid at this price point
Cons
- Thick, slightly gritty texture that some users find harder to layer under makeup
- Results are gradual — typically 4-8 weeks before redness and tone improvements are clearly visible
Who Should Buy The Ordinary Azelaic Acid Suspension 10%?
An excellent pick for anyone dealing with redness, rosacea-like flushing, or post-acne discoloration who hasn’t tolerated harsher actives well. It’s also a smart layer to add alongside (not instead of) a benzoyl peroxide or retinol routine for extra calming.
If you want fast, dramatic results, this is not that product — its strength is being gentle and consistent over weeks, not aggressive overnight.
How to Use It
- Apply a small amount to clean skin, once or twice daily.
- A slight tingling on application is normal and usually fades within a minute.
- Can be layered under moisturizer and, generally, under most other skincare actives.
- Give it 6-8 weeks of consistent use before judging results.
Our Verdict
This is one of the most underrated products in The Ordinary’s lineup — it doesn’t have the flashy reputation of niacinamide or retinol, but for redness, uneven tone, and gentle blemish control, it’s one of the safest, most versatile actives available at any price.
Frequently Asked Questions
Is azelaic acid safe for sensitive skin?
Yes — it has one of the gentler safety profiles among active acne/redness ingredients and is frequently recommended for rosacea-prone and sensitive skin, though patch testing is still a good idea.
Can I use this with vitamin C or retinol?
Generally yes. Azelaic acid is one of the more compatible actives and can typically be layered with both, though introducing new actives one at a time helps you track what your skin responds to.
How long until I see results?
Most people need 6-8 weeks of consistent daily use before seeing clear improvements in redness and tone — it works gradually rather than overnight.
