What it is

Naturium's Azelaic Acid Emulsion 10% is a lightweight, milky serum that pairs azelaic acid with niacinamide to address uneven tone, visible redness, and enlarged-looking pores. The emulsion texture sits between a traditional watery serum and a moisturizer, making it adaptable across a range of routines. At 10%, the azelaic acid concentration matches the threshold widely used in over-the-counter formulas for meaningful skin-tone improvement.

Who it's for

This formula suits anyone dealing with post-acne dark marks, melasma, or general uneven tone who prefers a gentle, non-irritating approach. It's especially compatible with oily and combination skin, since neither azelaic acid nor niacinamide adds meaningful occlusion. Sensitive and redness-prone complexions can also benefit—azelaic acid has well-established calming properties. Those with very dry skin will likely want to follow with a dedicated moisturizer. Anyone who is pregnant should confirm with their provider before use, though azelaic acid is generally considered one of the more cautious actives in that context.

How to use it

Start with once-daily application in the evening until your skin adjusts, then morning and evening if well-tolerated. After cleansing and any water-based toner, dispense a small amount and press it evenly across the face before moisturizer. Azelaic acid does not increase photosensitivity the way AHAs do, but daily SPF 30 or higher is still essential when treating hyperpigmentation—unprotected UV exposure will undermine results. This emulsion pairs well with hyaluronic acid serums applied underneath. Avoid layering it directly with strong retinoids or high-percentage vitamin C until you know how your skin responds.

Key ingredients

Azelaic acid (10%) is a dicarboxylic acid that inhibits tyrosinase, the enzyme responsible for excess melanin production. This makes it effective for fading post-inflammatory hyperpigmentation and smoothing uneven tone. It also carries recognized anti-inflammatory activity, which is why it is frequently recommended for acne-prone and redness-prone complexions. Niacinamide (vitamin B3) reinforces the skin barrier, helps regulate sebum production, and supports more even-looking tone by reducing melanin transfer to surface cells. Together, the two actives address pigmentation through complementary mechanisms, making the pairing logical rather than redundant.

Pros & cons

  • Delivers a clinically relevant 10% azelaic acid concentration in an accessible, non-prescription format
  • Niacinamide adds pore-minimizing and barrier-supporting benefits alongside the primary active
  • Emulsion texture works across oily, combination, and sensitive skin types
  • Targets multiple concerns—tone, redness, and pores—in a single step
  • Well-reviewed across more than 1,100 shoppers, with a 4.4 out of 5 rating
  • The 1 oz size runs small for twice-daily users
  • Visible improvement from pigmentation actives requires consistent use over weeks, not days
  • Dry skin types will likely need a separate moisturizer layered on top
  • Those with known sensitivity to niacinamide at higher concentrations should patch test before committing

How it compares

If brightening is the primary goal and you are open to a different active class, TruSkin Vitamin C Serum with Hyaluronic Acid & Vitamin E takes a vitamin C–first approach, which can be effective for oxidative dark spots and dullness. That said, vitamin C is pH-sensitive and should not be layered directly with azelaic acid in the same step. For shoppers whose main concern is hydration alongside tone correction, Tree of Life Hyaluronic Acid Serum for Face offers moisture-forward support, though without dedicated pigmentation actives. When the specific goals are redness and post-acne marks, the Naturium formula remains the more targeted option.

The verdict

The Naturium Azelaic Acid Emulsion 10% delivers a clinically relevant active concentration in a texture that is genuinely wearable across most skin types. The addition of niacinamide makes this a dual-mechanism approach to hyperpigmentation rather than a single-note serum. No topical active produces overnight results, and this one is no exception—but for consistent, low-irritation work on tone, redness, and pores, it earns a reliable place in a routine. The strong shopper ratings across a substantial review base point to dependable performance in real-world use. If your concerns are dark marks, visible redness, or enlarged pores, this is a well-formulated starting point.

What shoppers say

★ 4.4average from 1.1k ratings on Amazon

Shoppers with rosacea are the most vocal fans, with several reporting visible redness reduction faster than expected—even on dry, sensitive skin that typically can't tolerate exfoliating acids. Reviewers also credit it with clearing stubborn acne, fading dark spots, and resolving hard-to-treat periorbital dermatitis. The niacinamide pairing gets frequent praise for added calming benefits.

The main caveat comes from a dermatologist reference in one review: clinical rosacea treatment typically uses a 15% concentration, so the 10% formula may deliver slower or milder results for more severe cases. The 1 oz size also goes quickly if used twice daily.

Life changer for my rosacea

I bought this product after a youtube derm laid into this company's products. This was the only product she said she did consistently use, and could recommend. The derm did say that they use a 15% for rosacea and was unsure of how effective the 10% formula would be. For me, this has been a life saver. My rosacea flares up in heat and humidity, so living in the south this is a real problem. The flares are often pustules and red flaky skin that lasts for a week. I have used this product for 3 weeks, and the one potential flare was lessened greatly since using this product. I like that is has no fragrance, cruelty free, a pump dispenser, very budget friendly, and has not irritated my skin. I did not even have the usual hormonal breakout this month and I attribute that to this product. I also use Naturium's vitamin c and that product has the same pros, but I am unsure of the efficacy. I will continue using this product as my skin has cleared, and I am hoping to see lightening of my dark spots with continued use. **Edit 2022** Used the whole bottle. I found my skin did best when used every other night. Melasma spots dramatically faded and my rosacea calmed. I ran out and it was out of stock, so I ordered the Azelaic Acid Serum from Naturium, thinking it would yield similar results. The product was okay, did not like the dropper applicator, and my skin did not tolerate that formulation, it caused breakouts and irritation. So back to the emulsion I went and again my skin is happy. Sticking with this formula.

Resolved my periorbital dermatitis

If you end up with perioral or periorbital dermatitis, you'll find out that it's considered difficult to treat and can takes months to resolve. Derms often prescribe an antibiotic or antifungal. One other option derms will sometime prescribe is azelaic acid. I decided to try this in OTC strength since there was a wait to get a derm appt. I used this lotion 3-4x/day on my dermatitis and 2/x all over my face, and within days, I could see some improvement in the dermatitis. It still took a while to completely go away (3-4 weeks), but it finally resolved, and I felt there was some improvement in my rosacea & skin tone as well, so now this product is part of my routine. I also gave some to my mom & daughter, and both have asked for more. I've bought many bottles at this point for myself and various family members. This also can cause some flushing/tingling/burning, especially on the neck (which in many people is extra sensitive) or even on facial skin, especially if the skin barrier is damaged. When I use it on my neck, I dilute it with extra moisturizer. Some other notes: This product has EWG friendly ingredients which I consider a plus. The bottle is a little annoying because you can't see when you're running low, so I always make sure to have my next bottle on hand.

Rosacea Better in 2 Days!!!

I was very skeptical about using an “acid” on my dry, sensitive, rosacea-prone skin. I was afraid it would irritate. But after a recent outbreak of rosacea, I did a lot of research and decided to try Azelaic Acid. I picked this brand because it also contains niacinamide, which calms irritated skin. I washed my face with a gentle cleanser the first night, then added this product and waited 30 minutes before applying moisturizer because I’ve read it’s not effective to let azaleic acid sink in before using moisturizer. When I woke up, I could feel that my rosacea had improved. The next night I did the same routine and now my rosacea is about 80% cleared! I am AMAZED!! I do find it drying, so moisturizer is a must. My skin feels incredibly smooth and, as I said, the rosacea is almost gone. I cannot believe how well this has worked and I will be using this product for as long as they make it!!!

An effective product for acne and hyperpigmentation

I have been using Naturium azelaic acid for a few weeks and I am very satisfied with the results. My skin was prone to acne and had some dark spots, but since I started using this product, I have noticed a great improvement. Azelaic acid is known for its antibacterial and anti-inflammatory properties, and this product does not disappoint. It has helped reduce the appearance of pimples and fade the dark spots on my skin. The texture of the product is light and absorbs quickly, making it perfect for use during the day or night. It doesn't have a strong smell and doesn't irritate my skin, which is a great plus.

Genuinely impressed, reduction in redness from rosacea

Skin type: 40s, dry, rosacea, sensitized to essential oils. I, like many of us who are aging, experience dullness and loss of effectiveness for skincare products due to dead skin cells hanging out longer than they’re welcome. With rosacea, your typical AHAs and BHAs are not something you should use, they’re just too harsh and irritating. But physical exfoliation is also too harsh, it’s very easy to accidentally wipe too hard, even the gentlest Buf-Puf or konjac has the potential to mess your skin up. What’s a gal to do? I’d heard constantly azlaic is the way to go with sensitive rosacea skin, but when I was looking in Canada, it wasn’t available OTC - though this changed without my knowledge in 2022. When I moved back to the USA, I began looking into it as an OTC while finding a job with insurance. I’m very impressed by this product. The first time I used it, the next day my rosacea flared pretty badly. I was dismayed as I hadn’t had a flare that bad since I quit drinking. I persisted, because of all the folks online raving about azelaic acid and the benefits they’ve seen while using it. I had initially ordered a different product and didn’t think to read the ingredients. When I got it, I discovered lavender oil was in it. I’m allergic to the point exposure typically requires cortisone to heal. It’s so irresponsible to put essential oils in skincare products, once you’re sensitized you can’t go back. But this product’s ingredient list is clean from essential oils. So, even if the price point is higher, I opted to purchase this product on a gamble to try to help my skin feel and look better. I’ve used this 5 times. I used it every 3 days for 4 treatments, then I got sick and my raw nose made me worried it would sting like crazy and end up with a chemical burn. I tentatively used it again last night, but did not experience any stinging and I didn’t wake up to a bright red nose. What have I noticed in 5 uses? My skincare products are more effective, which was the primary goal. I can feel smoother skin, which is a chicken or the egg, but regardless, my skin feels nicer to the touch. But what I’ve really noticed is that my rosacea is a lot calmer. I was genuinely not expecting a quick response beyond skin cell turnover. An odd darker patch on my nose is visibly lighter, I’ve been concerned about it for a while and I’m happy to see it is lighter. I’m not imagining it either, it’s dramatically different. I’m not saying this is for all rosacea sufferers - it does have a plant extract that used as an alternative to retinol (which I have avoided due to knowing it can be very irritating for those with rosacea), and this may not work for you. I am not a dermatologist. For me, I am currently fine with this product’s formulation. I do have a referral for a derm and I’m looking forward to continuing to improve my skin. As is standard, but especially when using acids as part of your skincare routine: WEAR SUNSCREEN. Trust me, it’s not worth it to forget. Find one that works well for you and use it religiously. It’s the number one thing you can do for better skin, for life. Even if you haven’t been using it, the sooner you start, the more damage you prevent and lower your risk of skin cancer. This goes for everyone including those with melanin! Be careful with and kind to your skin, it’s the only skin you’ll ever have.

Naturium Azelaic Acid Emulsion 10% with Niacinamide, 1 oz: frequently asked questions

What does the Naturium Azelaic Acid Emulsion 10% actually do?

This lightweight emulsion combines 10% azelaic acid with niacinamide to target dark spots, uneven skin tone, redness, and enlarged pores. Azelaic acid works by inhibiting the enzyme that triggers excess melanin production, while niacinamide helps calm inflammation and regulate sebum. The emulsion texture absorbs quickly without a heavy or greasy finish.

Does azelaic acid lighten dark spots?

Yes — azelaic acid is clinically recognized for fading post-acne marks and hyperpigmentation by slowing tyrosinase activity, which reduces melanin overproduction. This formula pairs it with niacinamide for added brightening support. Results typically take several weeks of consistent use; it works gradually rather than dramatically fast, which is worth setting expectations around.

How do you use the Naturium Azelaic Acid Emulsion?

Apply a small amount to clean, dry skin after any water-based serums and before moisturizer. It can be used morning or evening — if used during the day, follow with broad-spectrum SPF, since active acids increase sun sensitivity. Start with every other day if you have sensitive skin and work up to daily use as tolerated.

What should you not mix with azelaic acid?

Avoid layering azelaic acid directly with other strong exfoliating acids (like glycolic or salicylic acid) in the same routine, as combining actives can cause irritation and compromise your skin barrier. Niacinamide — already in this formula — is actually a compatible and complementary ingredient. Retinoids can be used in the same routine but are best applied at a different time of day.

Can I use this azelaic acid emulsion every day?

Most users can work up to daily use, morning or evening. Because 10% is a moderately active concentration, people with sensitive or reactive skin should start every other day to let skin acclimate. Consistent daily use is where you'll see the most visible improvement in tone and redness over time.

Is this better suited for oily skin or dry skin?

The emulsion format and niacinamide combination make it particularly well-suited for oily and combination skin types — niacinamide helps regulate sebum and minimize pore appearance. That said, the emulsion texture is light enough for most skin types. Those with very dry skin may want to follow with a richer moisturizer to prevent any tightness.

Do I apply azelaic acid before or after moisturizer?

Apply the Naturium Azelaic Acid Emulsion before your moisturizer. A general layering rule is thinnest to thickest, so this emulsion goes on after cleansing and any lightweight serums, then seal everything in with your moisturizer on top. Applying it under moisturizer ensures the active ingredients can absorb into the skin properly.
