Azelaic Acid Gel: What You Need to Know

Let’s be real for a second.

You’ve probably seen “azelaic acid gel” floating around skincare forums, dermatologist offices, or even your own prescription bottle. You’re curious. Maybe you’re frustrated. Maybe your skin’s been acting up—red, bumpy, stubborn—and you’re just looking for something that actually works without wrecking your barrier.

So here’s the straight-up answer: azelaic acid gel is one of those quiet heroes in dermatology. Not flashy, not loud, but seriously effective—especially if you’re dealing with rosacea, acne, or those pesky dark spots that just won’t quit.

And no, it’s not just another hyped-up ingredient. It’s FDA-approved. It’s backed by science. And the best part? It tends to be gentle—even for sensitive skin.

But like any good skincare player, it’s not magic. It takes time. It might tingle at first. And honestly? It’s easy to get confused, especially when you’ve got prescription versions like azelaic acid gel 15% side-by-side with popular drugstore picks like The Ordinary Azelaic Acid Suspension 10% or Naturium Azelaic Acid.

So let’s cut through the noise. I’m going to walk you through what azelaic acid gel really does, who it’s for, how to use it right, and why it might just be the missing piece in your routine.

What It’s For

First things first: what is azelaic acid gel actually approved to treat?

According to the FDA, prescription-strength azelaic acid gel 15% is specifically indicated for treating the inflammatory papules and pustules of mild to moderate rosacea. Yep, those red, angry bumps on your cheeks and nose? This stuff is designed to calm them down.

Now, here’s something important: it’s not meant to treat general facial redness (what doctors call erythema) all on its own. At least, not officially. The clinical trials didn’t evaluate that use case when it was approved according to DailyMed. But—big but—many people do notice their overall redness improves over time, especially because calming inflammation helps with that flushed look.

And while it’s approved for rosacea, dermatologists often prescribe it off-label for acne. Why? Because azelaic acid works in three ways:

• It reduces inflammation (hello, red pimples).
• It gently exfoliates dead skin cells, keeping pores clear.
• It has antimicrobial properties that target acne-causing bacteria.

So if you’re dealing with inflammatory acne—those red, swollen bumps—this gel could be a solid option, especially if stronger treatments like retinoids or benzoyl peroxide irritate your skin.

Oh, and bonus: it also helps with post-inflammatory hyperpigmentation (PIH). You know, those dark or red marks left behind after a pimple heals? Azelaic acid can fade them by gently inhibiting melanin production. This makes it especially popular among people with darker skin tones who need effective but non-irritating treatments.

How To Use It

Alright, so you’ve got the gel. Now what?

Using azelaic acid gel the right way makes a huge difference in how well it works and whether your skin tolerates it.

The standard routine? Apply a thin layer twice daily—morning and night—after cleansing and before moisturizing. That’s it. No need to slather it on. A little goes a long way.

Here’s a quick step-by-step:

1. Cleanse with a gentle, fragrance-free, non-abrasive cleanser. Avoid anything with alcohol, scrubs, or strong acids—especially at first.
2. Pat your face dry with a soft towel. Don’t rub.
3. Use a pea-sized amount and spread it evenly over your entire face or affected areas. Don’t just dab it on individual pimples—this is a treatment, not a spot treatment.
4. Wait 3–5 minutes for it to absorb before layering on moisturizer or sunscreen.
5. Wash your hands immediately after. Trust me, you don’t want this near your eyes.

And about that stinging feeling? Yeah, it might tingle a bit in the first few weeks. That’s normal. But if it burns constantly or your skin turns bright red, scale back. Maybe start with once a day, or every other day, and build up slowly.

Also—don’t mix it with harsh products right away. Give your skin time to adjust. Once you’re comfortable, you can layer it with hydrating serums like hyaluronic acid or niacinamide. Just avoid pairing it with strong exfoliants (like glycolic or salicylic acid) unless your skin is already rock-solid.

Prescription vs OTC

Now, let’s talk about the elephant in the room: what’s the difference between the prescription azelaic acid gel 15% and the drugstore versions like The Ordinary Azelaic Acid Suspension 10% or Naturium Azelaic Acid?

It’s not just about strength—though that’s part of it. The prescription version is 15% azelaic acid, clinically tested, and regulated. It’s what your dermatologist prescribes when you need real treatment, not just maintenance.

Meanwhile, The Ordinary’s formula is 10% azelaic acid, mixed with silicones and other texture-enhancing ingredients. It’s gentler, more affordable, and great for keeping skin smooth and bright—but it’s not going to pack the same punch as the 15% gel if you’re dealing with moderate rosacea or persistent breakouts.

Same goes for Naturium Azelaic Acid—also 10%, but with added hydrators like glycerin and panthenol. It’s formulated to be soothing, which is great if your skin is reactive. But again, it’s not a replacement for medical-grade treatment when you need one.

Here’s a quick way to think about it:

Product	Strength	FDA-Approved?	Best For
Azelaic Acid Gel 15%	15%	Yes	Rosacea, inflammatory acne, medical treatment
The Ordinary Azelaic Acid	10%	No	Maintenance, texture, mild concerns
Naturium Azelaic Acid	10%	No	Hydration + gentle brightening

If your skin is really struggling? Go the prescription route. If you’re just keeping things in check or on a budget? OTC versions can work well as part of a routine.

Side Effects

No skincare product is perfect—and azelaic acid gel is no exception.

The most common side effects? Burning, stinging, tingling, dryness, and mild redness. According to clinical trials, about 29% of users reported some kind of stinging sensation—especially in the first few weeks based on FDA data.

But here’s the good news: for most people, this fades as the skin builds tolerance. Think of it like breaking in a new pair of shoes. It might pinch at first, but it gets better.

Now, a rarer but important risk: hypopigmentation. There have been isolated cases where long-term use led to lightened skin patches, especially in people with darker complexions. It’s not common, but it’s worth monitoring. If you notice areas of your skin turning lighter, stop using it and talk to your dermatologist.

And if you have asthma? Pay attention. There are post-market reports of azelaic acid gel possibly worsening asthma symptoms as noted in prescribing information. Not common, but worth knowing. If your breathing feels worse after starting the gel, don’t ignore it—talk to your doctor.

Oh, and keep it away from your eyes. It can sting like crazy if it gets in there. If it does, rinse with cool water and stop using it near the eye area until you’re sure it’s safe.

Who Should Use It

So who actually benefits most from azelaic acid gel?

Great question.

It’s fantastic for people with rosacea, especially if you get those red, inflamed bumps. It’s also a go-to for acne-prone skin that’s sensitive to stronger treatments. And if you’re dealing with post-acne marks or melasma? This might be one of the gentlest ways to brighten without irritation.

But what about during pregnancy or breastfeeding?

Good news: azelaic acid is generally considered safe. It’s minimally absorbed into the bloodstream, and it’s naturally found in the body and in foods like whole grains. Still, always check with your OB-GYN or dermatologist before starting anything new—especially when you’re expecting.

What about teens? The safety in children under 18 hasn’t been fully established, so it’s typically not recommended for younger users unless a doctor says otherwise.

And older adults? No major issues reported. In fact, many long-term users find it helpful for both acne and skin tone evening as they age.

If you have sensitive skin? You might still be able to use it—just start slow. Patch test behind your ear or on your jawline. Use it once a day for a week. See how it feels. If your skin’s happy, you’re good to go.

Why Trust This?

Look, I get it. There’s a lot of skincare advice out there—some helpful, some not so much.

But this info? It’s pulled straight from FDA-approved prescribing documents, clinical trial data, and dermatologist-backed research. No fluff. No marketing. Just what’s been tested, proven, and used by real people.

And I’m not here to sell you anything. I’m here because I’ve seen how frustrating skin issues can be. How a simple red bump can knock your confidence. How hard it is to find something that actually works without making things worse.

That’s why I focus on what’s real, what’s safe, and what’s actually helpful—because you deserve that.

The Bottom Line

At the end of the day, azelaic acid gel isn’t a miracle. It’s not going to transform your skin overnight. But it is one of the most balanced, multitasking, and well-tolerated treatments out there.

Whether you’re using the prescription 15% gel or an OTC version like The Ordinary Azelaic Acid Suspension 10% or Naturium Azelaic Acid, the key is consistency and patience.

Give it time. Be kind to your skin. And don’t rush the process.

Because good skin isn’t about quick fixes. It’s about finding what works for you—and sticking with it.

So if you’ve been on the fence about trying azelaic acid? Maybe now’s the time. Talk to your dermatologist. Do a patch test. Start slow.

And if you’ve already tried it—what’s your experience been like? Did it calm your redness? Fade your marks? Or was it just too much for your skin?
