What Is The Ordinary Azelaic Acid Suspension 10%?

The Ordinary is a Canadian skincare brand under the DECIEM group, well known for its no-frills, science-first approach to skincare. Rather than dressing up their products with fancy packaging and vague claims, The Ordinary puts the key ingredient front and center — and tells you exactly what concentration you’re getting.

Their Azelaic Acid Suspension 10% is exactly what it sounds like: a formula containing a 10% concentration of azelaic acid suspended in a cream-gel base. The product is designed specifically for those dealing with blemish-prone skin, uneven skin tone, and textural irregularities.

According to The Ordinary, the formula targets:

• Dullness and uneven skin tone
• The look of redness (including rosacea-prone skin)
• Rough, uneven skin texture
• The appearance of blemishes and post-acne marks

At under $15 for a 30ml tube, the price point alone makes this product extremely appealing. But does it actually deliver? Let me walk you through everything.

What Is Azelaic Acid — And Why Should You Care?

Before we get into the review itself, let’s talk about the star ingredient: azelaic acid.

Azelaic acid is a naturally occurring dicarboxylic acid found in grains like wheat, rye, and barley. It’s also produced naturally by the yeast that lives on healthy skin. In cosmetics, the version used is typically lab-synthesized to ensure purity and consistency.

What makes azelaic acid so special is how multi-functional it is. Here’s what it does:

• Inhibits melanin production — it works by blocking tyrosinase, the enzyme responsible for producing pigment. This means it can visibly fade dark spots, hyperpigmentation, and post-acne marks over time.
• Antibacterial properties — it targets acne-causing bacteria, making it effective for blemish-prone skin.
• Anti-inflammatory — it calms redness and irritation, which is why it’s frequently recommended for people with rosacea.
• Mild exfoliating action — it helps unclog pores and smooth out rough texture.
• Antioxidant support — it helps neutralize free radicals, offering some protection against environmental damage.

One more thing that makes azelaic acid stand out in the world of actives: it does not make your skin photosensitive. Unlike AHAs and retinol, you don’t have to worry about sun sensitivity when using it — though SPF is always a good idea regardless.

Key Ingredients Breakdown

The Ordinary is famously transparent about what goes into their formulas. Here’s a closer look at the key players in the Azelaic Acid Suspension 10%:

Azelaic Acid (10%)

The headline ingredient at a 10% concentration. This is a high-purity form of azelaic acid that works to brighten, smooth, and calm the skin. It’s worth noting that prescription formulas in the US often go up to 15–20%, but 10% is effective for general skincare use and is available over the counter.

Dimethicone

A silicone that forms a light protective layer on the skin, reduces water loss, and gives the product that smooth, velvety application feel. It also temporarily fills in fine lines and absorbs surface oil.

Dimethyl Isosorbide

A delivery enhancer derived from glucose. It penetrates deep into the skin and helps carry active ingredients like azelaic acid further into the layers where they can do their work most effectively.

Tocopherol (Vitamin E)

A pure form of Vitamin E that acts as an antioxidant, protecting the skin from free radical damage. It also helps maintain the skin’s lipid barrier and works synergistically with Vitamin C to enhance overall skin protection.

Isodecyl Neopentanoate

An emollient that softens and smooths the skin, contributing to the formula’s comfortable finish.

The full formula is free from harsh alcohols, fragrances, oils, parabens, and sulfates — making it a relatively clean and low-irritation option.

Texture, Scent & Application Experience

Let’s talk about what it actually feels like to use this product — because texture is where people tend to have the most divided opinions.

The Azelaic Acid Suspension 10% has a thick, cream-like consistency that feels almost waxy when you first pick it up. It’s white in color, opaque, and noticeably heavier than a typical serum. When you rub it between your fingers and apply it to your face, it spreads reasonably well but does leave a subtle film on the skin.

The formula is fragrance-free, which is excellent for those with sensitive skin. There’s a very mild, faintly neutral scent — nothing off-putting.

Application tip: A pea-sized amount is truly all you need for the entire face. Go in with slightly damp skin and use gentle patting motions rather than rubbing for a smoother finish. Always follow with moisturizer, especially if you have dry or combination skin.

One thing worth noting: because of the silicone-heavy base, some people experience pilling when layering other products on top — particularly powder sunscreen or foundations. If this is a concern for you, apply it as the last step in your skincare routine at night, or give it ample time to absorb before applying makeup in the morning.

My Experience Using It

I incorporated The Ordinary Azelaic Acid Suspension 10% into both my morning and evening routines, applying a small amount to clean skin before moisturizer.

In the first two weeks, I honestly didn’t notice much change — which is normal with azelaic acid. It’s not the kind of ingredient that produces dramatic overnight results. I did notice my skin felt calmer overall, with slightly less visible redness around my nose and cheeks.

By weeks three and four, I started seeing more meaningful changes. The dark spots I’d been dealing with from old blemishes looked a bit lighter, and my skin tone appeared more even in general. My pores also looked slightly less congested.

After consistent use over six to eight weeks, the results were genuinely noticeable. My skin was smoother, brighter, and the hyperpigmented areas had visibly faded. I didn’t experience any major breakouts during this period, and the occasional blemish I did get healed faster and left less of a mark behind.

For those with sensitive or dry skin: I would recommend starting with every other night to let your skin adjust, then building up to daily use. A very small number of users may experience mild initial redness or a slight tingling sensation — this typically settles with consistent use.

Who Is This Product Best For?

The Ordinary Azelaic Acid Suspension 10% is a genuinely versatile formula, but it shines most for specific skin concerns:

• Post-acne hyperpigmentation — if you’re left with dark spots and marks after blemishes, this is one of the best over-the-counter options available at this price point.
• Uneven skin tone — whether from sun damage, hormonal changes, or general dullness, azelaic acid’s melanin-inhibiting properties make a real difference.
• Rosacea-prone skin — the anti-inflammatory action of azelaic acid makes this formula particularly suitable for those dealing with redness and rosacea flare-ups.
• Acne-prone skin — the antibacterial properties help prevent future breakouts while fading the aftermath of existing ones.
• Sensitive skin types — azelaic acid is widely recognized as one of the gentler actives, making it a great option for those who find retinol or high-concentration AHAs too irritating.

If you have oily or silicone-sensitive skin, the heavy silicone base of this particular formula may not be ideal for you. In that case, a water-based azelaic acid gel format might suit you better.

How to Use It in Your Routine

Getting the most out of this product comes down to proper layering. Here’s a simple guide:

Pros and Cons

What I Love

• Exceptional value — effective active at a price point almost anyone can access
• Fragrance-free, paraben-free, and oil-free
• Suitable for sensitive, rosacea-prone skin
• Does not cause photosensitivity
• Visibly fades hyperpigmentation with consistent use
• Calms redness and inflammation
• Vegan and cruelty-free

Things to Keep in Mind

• Thick, silicone-heavy texture may not suit all skin types
• Can pill under makeup or powder sunscreen if not given time to absorb
• Results require patience — expect 6–8 weeks for visible improvement
• May feel heavy on very oily skin

Final Verdict

The Ordinary Azelaic Acid Suspension 10% is, in my experience, a genuinely effective and accessible skincare product — especially for those dealing with post-acne marks, uneven skin tone, or rosacea-related redness. The 10% concentration of azelaic acid is well-formulated, and the addition of delivery enhancers like Dimethyl Isosorbide helps the active ingredient penetrate effectively.

Is the texture for everyone? No — the silicone-heavy suspension can feel heavy, and pilling is a real consideration for those with oily skin or complex layering routines. But for the price, the quality of the active ingredient and the results it delivers over time make this a standout addition to any anti-aging or brightening skincare routine.

If you’re new to azelaic acid, this is one of the most affordable and approachable ways to try it. Give it six to eight weeks of consistent use, pair it with a good SPF, and let the results speak for themselves.

Overall Rating: 4.2 / 5 ⭐
