Posted by Skinsider Team on 29th Apr 2025

In the ever-evolving world of skincare, finding that hero ingredient that truly tackles multiple concerns can feel like striking gold. Enter azelaic acid, a naturally derived powerhouse that's been quietly working wonders for various skin issues. From calming redness to tackling breakouts and brightening your complexion, this gentle yet effective ingredient deserves a spot in your routine. Today, we'll delve into the azelaic acid benefits and explore how the Korean skincare experts at Nine Less have harnessed its potential in their dedicated A-Control line.

What is Azelaic Acid?

So, what is azelaic acid exactly? It's a dicarboxylic acid found naturally in grains like barley, wheat, and rye. While it's a naturally occurring substance, the azelaic acid used in skincare is typically produced in a lab for purity and consistency. It's well-regarded in dermatology for its ability to address a range of skin concerns without the harshness associated with some other active ingredients.

What Does Azelaic Acid Do For Your Skin? Azelaic Acid Benefits

You might be wondering, what does azelaic acid do? This multitasking marvel works through several key actions:

Fights Acne: It has antibacterial properties, meaning it can help to eliminate the bacteria that contribute to acne. It also helps to normalise skin cell turnover, preventing clogged pores – a primary culprit in breakouts. So, is azelaic acid good for acne? Absolutely, and does azelaic acid help with acne? Yes, it's a well-established treatment.

Reduces Inflammation: Azelaic acid is a potent anti-inflammatory. This makes it particularly beneficial for conditions like rosacea, helping to soothe redness and visible blood vessels. Therefore, is azelaic acid good for rosacea? Many find significant relief using it.

Brightens Skin and Fades Hyperpigmentation: It inhibits the enzyme tyrosinase, which is involved in melanin (pigment) production. This means it can help to fade dark spots, post-inflammatory hyperpigmentation (PIH) left after acne, and even out your overall skin tone.

Gently Exfoliates: While not a harsh exfoliant like some AHAs or BHAs, is azelaic acid an exfoliant? Yes, it does possess mild keratolytic properties, helping to shed dead skin cells and refine skin texture without causing significant irritation.

How to Incorporate Azelaic Acid into Your Routine?

Knowing the benefits is one thing, but how to use azelaic acid effectively is crucial. Generally, it's applied after cleansing and toning and before your moisturiser. You can use it once or twice daily, depending on your skin's tolerance.

How Often to Use Azelaic Acid?

Starting with once a day, preferably in the evening, allows your skin to adjust. If you experience no irritation, you can gradually increase to twice daily for enhanced results. Always listen to your skin and adjust accordingly. Don't forget to follow up with a good moisturiser and, during the day, a broad-spectrum sunscreen to protect your skin.

Azelaic Acid and Other Actives: Can They Play Nicely?

A common question is, can you use azelaic acid with retinol and other active ingredients? The good news is that azelaic acid is generally well-tolerated and can often be used alongside other skincare heroes. For instance, can you use azelaic acid with vitamin C? Yes, many find this combination beneficial for brightening and antioxidant protection.

When using it with more potent exfoliants like retinol or AHAs/BHAs, it's wise to introduce them gradually and monitor your skin for any signs of irritation. You might consider using them at different times of the day (e.g., azelaic acid in the morning, retinol at night) or on alternate days.

Patience is Key: How Long Does Azelaic Acid Take to Work?

It's important to have realistic expectations. How long does azelaic acid take to work? While some may see initial improvements within a few weeks, noticeable results typically appear after 4 to 6 weeks of consistent use, especially for concerns like acne and redness. Fading hyperpigmentation may take longer. Consistency is key to seeing the full benefits of azelaic acid. You might also see the question how long for azelaic acid to work – the answer remains the same: stick with it!

Is Azelaic Acid Good for Rosacea?

For those battling the persistent redness, flushing, and sometimes bumpy texture of rosacea, the answer is a resounding yes for many individuals. Its potent anti-inflammatory properties help to calm the skin, reducing the visible redness and the appearance of inflamed papules and pustules often associated with rosacea. Furthermore, azelaic acid can help to normalise the overactive blood vessels in the skin that contribute to flushing. Its gentle action makes it a well-tolerated option for sensitive, rosacea-prone skin, offering a path to clearer and more comfortable skin without the harshness of some other acne or redness treatments. Many dermatologists recommend azelaic acid as a key ingredient in managing rosacea symptoms, and incorporating products like the Nineless A-Control range can be a soothing and effective step in your skincare journey.
