Azelaic Acid vs Niacinamide: Which Is Best for Your Skin?

by Ella Goodman 17 Apr 2024

Buckle up, skincare enthusiasts! 

We're about to deep dive into the swirling world of beauty potentates – azelaic acid vs niacinamide. 

Let's demystify these active ingredients, dish out some skin-loving tips, and debunk your burning questions. 

And above all, let’s answer the million-dollar question: which of these two star performers is better for your skin?

Is niacinamide better than azelaic acid?

Hang onto your lab goggles, we're diving into the science of skincare with our two superstar ingredients. 

These two have been prancing around the skincare arena for some time, stirring interest, and leaving us in a shuffle of confusion. 

So let's roll up our sleeves and scrutinize these buzzing beauty buzzwords. 

Now, “Better” can be a tricky term in the wide world of skincare. It's a lot like asking if strawberries are better than blueberries - both are super nutritious, but which one takes the gold depends on what you're after. 

The same holds true for niacinamide and azelaic acid.

Let’s chat about niacinamide first, the skincare community's darling. 

It's a fabulous form of vitamin B3, renowned for its ability to build proteins in the skin and lock in moisture. That's right, it's like a bouncer for your face, keeping the good stuff in and the bad stuff out. 

Now, turn your attention to azelaic acid. 

This lesser-known gem might sound a bit intimidating (what with being an acid and all), but it's a surprisingly gentle and highly effective multitasker. With anti-inflammatory properties, it's a total virtuoso at calming those red, inflamed spots. 

*Chef's kiss* to that.

The differentiation between these two, then, lies in their primary areas of expertise. 

Niacinamide is your hydration hero, rebalancing your oil production and keeping your skin plumper than a well-rested marshmallow. Azelaic acid, on the other hand, holds the scepter when it comes to reducing inflammation and evening out skin pigmentation.

Maybe you're thinking, "I have oily skin and acne. Which is better for me?" 

The answer? Feel free to invite both to your skincare cocktail party! Their functions magically complement each other. Niacinamide can control the oil production that may be responsible for your breakouts, while azelaic acid can calm the inflammation and even out the skin tone after a breakout. 

Thinking of wrinkles? Niacinamide is your ticket. It bolsters collagen production—the scaffolding that holds up your skin—to ensure firmness and elasticity. Azelaic acid takes the backseat here; it's not the main guest at the anti-aging gala. 

Or maybe, you're grappling with rosacea or redness? In that case, azelaic acid may be more your speed. It's like a mini fire extinguisher, tackling inflammation and reducing the appearance of red blotches. Niacinamide, although not the star of the show, can offer some backup support.

To sum it up, is niacinamide better than azelaic acid? It's not an apple-to-apple comparison. 

Both have their unique powers; they’re like Batman and Superman of your skincare routine, each having their own specific talents and areas where they shine. 

Can I use niacinamide and azelaic acid together?

Oh, you've got a skin query that's as unique and intriguing as a detective novel! 

The case at hand: Can you use niacinamide and azelaic acid together? 

Let’s examine the evidence and crack this case wide open. 

It all comes down to chemistry, and not the rom-com kind. So let’s take a more scientific look at our two heroes.

Here's the skinny. Niacinamide is your skin’s best friend, performing a variety of roles. It helps to reduce inflammation, lighten hyperpigmentation, and even boost the production of ceramides to keep your skin barrier strong. 

On the flip side, we've got azelaic acid, an unsung hero of the beauty world. It fights against acne, reduces inflammation and lightens the skin too. Quite the resume, wouldn't you say?

Seems they both are wonder workers, but can they work wonders together? Drumroll, please... 

Yep, they can! You absolutely can use niacinamide and azelaic acid together.

Get ready for some serious skincare science.

The reason niacinamide and azelaic acid can play well together is their similar pH range. Both have a close-to-neutral pH range of 4.5-5.5 which is identical to our skin's natural pH level. This means these two ingredients can coexist without deactivating each other, or worse, causing irritation to your skin. 

To translate that science-speak into everyday language, using these two together is a bit like serving both chocolate and vanilla ice cream at a party. They're different flavors that coexist amicably, without clashing or melting into a strange, unpresentable blob. 

And although they play nicely together, you still need to listen to your skin. 

Patch testing, while not as glamorous as a masquerade ball, is equally important. Your skin, like your favorite book, can hold surprises. 

Apply a small amount of niacinamide followed by azelaic acid on a tiny area of your skin. If no redness or irritation emerges after 24 hours, then you can confidently include these in your regular skincare regimen. 

Always, we mean always, use sunscreen during the day. Just like a really good mystery novel, niacinamide and azelaic acid will keep you hooked, but the UV rays can become potential spoilers.

So, to demystify all the detective work, yes! You can indeed use niacinamide and azelaic acid together. 

But how do you get them to work harmoniously? 

Sequence is the secret! And on that topic… 

Do you use niacinamide or azelaic acid first?

Picture your skincare routine as a concert—you wouldn’t call on the headliner before the opening act, would you?

Start with niacinamide, then apply azelaic acid. 

Niacinamide is your opening act for a good reason. Water-soluble, light, and non-acidic, it preps and primes your skin for what's to come. Being a pH-tolerant ingredient, it gets along swimmingly with other ingredients in your skincare mix, making it the ideal ice-breaker at this skin-party.

Next up, enter azelaic acid, your headliner. 

Heavier, stronger, and just a bit more intense. It needs extra time to penetrate your skin and work its magic. Niacinamide’s preparation now allows for the azelaic acid to sink deep and crank up its performance to 11.

Look, no one's saying it's a major catastrophe if you mix up the order now and then. But when it comes to getting the most bang for your skincare buck, it's niacinamide first, and then azelaic acid. 

But remember: preparation is key. Always cleanse before applying these gems to ensure your skin is squeaky clean. Dirt and excess oils can hinder these star ingredients from doing their best work.

And don’t forget to follow up with a moisturizer to seal in all that goodness. It's like the encore at the concert—you just wouldn't skip it!

Lastly, a word of caution. Just because these two play well together, doesn't mean they can't cause a ruckus with other skincare ingredients. 

When it comes to combining these with other actives like retinol or high-concentration AHAs and BHAs, it's a different ball game. 

Consider that your PSA to stay tuned for our future deep dives into skincare layering!

Is azelaic acid better than niacinamide for hyperpigmentation?

Choosing between azelaic acid and niacinamide is similar to deciding who your favorite movie star is – both deliver fantastic performances for treating hyperpigmentation. 

Even though the mechanisms of action differ, both diligently work towards one key objective - controlling melanin production, the main culprit behind those pesky skin discolorations. 

When it comes to azelaic acid, it acts as a direct tyrosinase inhibitor. It decreases melanin production right at the source, like your forthright, tell-it-like-it-is friend who helps you tackle the issue head-on. In other words? It’s a total pro at removing dark spots.

Niacinamide, though, takes a more subtle approach. It controls the movement of melanosomes (those teeny pigment-charged parcels) to the surrounding skin cells. Picture it as your suave, behind-the-scenes friend who promotes resolution without the fanfare or dramatics.

Now get your glow on!

And that brings us to the grand finale! 

One final note - the ultimate power of skincare doesn't lie in a single ingredient. It's all about understanding your skin’s unique rhythm and curating a care routine that caters to its specific needs. 

Whether you roll out the red carpet for azelaic acid, niacinamide, or decide to include both in your all-star cast, remember to keep the experience fun and rewarding. 

Here's raising a toast to your stunning skin!
