Can You Use Azelaic Acid and Salicylic Acid Together? Here’s the REAL Answer

by Ella Goodman 18 Oct 2023

Hey skin-care enthusiast!

If you've been on a mission to get your skin looking its most fabulous self, you've probably come across two big players in the beauty world: azelaic acid and salicylic acid.

Sure, they're a bit of a mouthful, but are they a dynamic duo that could be the answer to your skin's dreams?

Let's find out.

Can I Use Salicylic Acid with Azelaic Acid?

Alright, let's get right to it. You've got your azelaic acid in one hand and your salicylic acid in the other, wondering if they can coexist on your precious face.

Good news, skincare warrior! They absolutely can!

But, like any power couple, it's all about balance.

Let's start with the basics: What are these acids?

Azelaic acid is a naturally occurring acid found in grains like barley and wheat.

It's known to be a gentle giant in the skincare world – gentle on your skin but tough on skin concerns.

Its superhero abilities include calming inflammation (bye-bye, redness!), unclogging pores (adios, blackheads!), and targeting hyperpigmentation (see you never, dark spots!).

Salicylic acid, on the flip side, is a beta hydroxy acid (BHA) with a penchant for oil-busting.

Derived from willow bark, this acid is oil-soluble, meaning it can penetrate those oily pores and perform deep exfoliation. It's a zit-zapper, breakout-buster, and overall pore cleaner-upper!

So, can they blend?

To reiterate - you bet they can!

Imagine a world where azelaic acid is working its charm on your hyperpigmentation, while salicylic acid is deep diving into those pores, evicting any unwelcome gunk.

Together, they can elevate your skincare game. It's like pairing a smooth glass of red wine with the finest cheese—each complements the other, offering a harmonious experience that’s both effective and invigorating.

However, like any star-studded duo, it's all about understanding and respect

Here's the science-y bit.

Azelaic acid works its magic on the skin’s surface, tackling inflammation and pigmentation. Salicylic acid, because of its unique oil-solubility, penetrates deeper, exfoliating inside the pores.

When these two collaborate, they address a spectrum of skin concerns from the surface to the depths of your pores.

But there's a catch: Overdoing it might overwhelm your skin.

So, how do we make this duo work seamlessly?

  • Understand Your Skin: Everyone's skin is unique. While most people can benefit from this power-packed combo, if your skin is super sensitive, it's all about moderation and careful layering.
  • Alternate First: Don't rush the process. Start with alternate days or even alternate weeks to see how your skin responds. Remember, skincare isn't a sprint; it's a marathon.
  • Monitor & Adjust: While these acids are generally well-tolerated, if you notice excessive dryness or irritation, it might be wise to scale back and adjust your routine.
  • Seek Expert Advice: If in doubt, a dermatologist or skincare expert can offer personalized advice. Remember, it’s all about achieving balance.

Wrapping it up, think of azelaic and salicylic acid as the latest power-duo in the skincare charts.

While both are superstars in their own right, when combined thoughtfully, they can produce a chart-topping hit for your skin.

How Do You Use Azelaic and Salicylic Acid Together?

Alright, we've established they can rock the skincare stage together, but how do you get them to harmonize without hitting a false note?

Here's your step-by-step guide to making magic:

1. The Sacred Rule: The Patch Test

Yes, we're starting with the golden rule of skincare!

You wouldn't jump into a pool without checking the water temperature, right? The same goes for these potent potions.

  • Why it’s vital: Everyone's skin is a unique canvas. What might be a wonder product for one could be a bit much for another. A patch test helps ensure that your skin vibes with this dynamic duo.
  • How to do it: Dab a tiny amount of both products (separately, not mixed) on a discreet patch of skin, like behind your ear or on your inner wrist. Wait for 24 hours. If there's no redness, itching, or other irritations, you're good to go!

2. The Art of Patience: Start Slow

Diving right in isn’t always the answer, especially when introducing new key players to your skin's routine.

  • Why it matters: By gradually introducing your skin to azelaic and salicylic acid, you reduce the potential for irritation. Plus, it gives you a chance to observe how your skin responds.
  • How to play it: Begin by applying each acid on separate days. As your skin builds its tolerance, you can graduate to using them together. But remember: The journey to radiant skin is a marathon, not a sprint.

3. Layering 101: Mastering the Sequence

The order in which you apply products isn’t just about preference—it's rooted in science!

  • Why the order is crucial: Salicylic acid, being oil-soluble, gets through the natural oils on our skin to dive deep into pores. On the other hand, azelaic acid works its wonders on the surface. Hence, salicylic first, then azelaic - IF, that is, you are indeed using them as separate ingredients. But more on that shortly!
  • The method: Cleanse your face and pat it dry. Apply a thin layer of salicylic acid, letting it absorb. Follow up with azelaic acid, gently massaging it in.

4. Don't Skip the Drink: Moisturize

The combination of these acids, while powerful, can leave your skin parched if overdone. Enter: your trusty moisturizer.

  • Why hydration is key: Acids can strip your skin of its natural oils, potentially leading to dryness and irritation. Moisturizing restores that essential hydration.
  • The routine: After giving your acids a moment to fully absorb, slather on your favorite moisturizer. Your skin will drink it up, and you'll be left with a supple, radiant complexion.

5. The Ultimate Life Hack: The Dual Serum

To really streamline your routine and ensure you're getting the right balance, consider using a serum that has both azelaic and salicylic acid.

  • Why it’s a game-changer: Simplifies your routine, ensures perfect proportion, and saves time. And let’s face it, we all like skincare that’s effective yet hassle-free.
  • How to incorporate: Cleanse, apply your dual serum, let it soak in, then follow up with moisturizer. Boom! Skincare routine simplified.

What Should You Not Mix with Azelaic Acid?

So, while azelaic acid is mingling harmoniously with salicylic acid and they're having a blast, there are a few ingredients azelaic acid might side-eye at a skincare party.

Let's break down the no-go zones with azelaic acid:

The Brightness Overload: Niacinamide

Yes, surprise!

Both azelaic acid and niacinamide are stellar at brightening the skin. So, what's the problem?

  • The Science: Niacinamide is all about boosting hydration and reducing redness. But, when paired with azelaic acid, it can get a little too intense. While niacinamide adjusts the skin's sebum activity, azelaic acid's potent properties can amplify this effect. This combo might lead to skin dryness for some.
  • How to Play Safe: If you're all in on both these brightening bad boys, consider alternating their use. Maybe niacinamide in the AM and azelaic acid in the PM? That way, you get the best of both worlds without overwhelming your skin.

The Power Duo That’s Too Powerful: Retinol

Retinol and azelaic acid are both high-achievers. But sometimes, combining two star players can lead to a clash.

  • The Science: Retinol accelerates skin cell turnover, revealing younger, fresher skin. On the flip side, azelaic acid is hard at work fighting inflammation, unclogging pores, and lightening dark spots. When they team up, they might be too effective, increasing the chances of skin sensitivity or even flaking.
  • The Pro Move: If you're not ready to give up either (and we don’t blame you), use them at different times. Think retinol nights and azelaic acid mornings. Ensure there’s ample time between applications, and always, ALWAYS, follow up with a good SPF in the morning, especially when retinol is in the mix.

The Unexpected Tangle: Benzoyl Peroxide

Here's an ingredient that doesn't usually come up in this conversation but deserves a mention.

  • The Science: Benzoyl peroxide is a go-to for many acne sufferers. It reduces acne-causing bacteria and helps clear out those zits. However, mixing it with azelaic acid can be a bit much for the skin. The combined drying properties of both might leave your skin begging for moisture.
  • The Strategy: If both are part of your skincare artillery, give your skin a breather between applications. Using one in the morning and the other in the evening can help, and again, moisturize like you’ve never moisturized before!

What Should You Not Mix with Salicylic Acid?

Salicylic acid, in its own way, is like that charismatic friend everyone wants at the party – it can make things lively, but pair it with the wrong crowd, and things could get a tad chaotic.

So, let's dive deep into the skincare mixtape to see who shouldn’t share the stage with our star, salicylic acid.

The Hydration Hijacker: Alcohol-Based Products

While it might seem counterintuitive, some skincare products are laden with alcohol.

No, not the fun margarita kind; we're talking about the drying kind.

  • The Science: Salicylic acid, by nature, can be a bit drying since it's exfoliating and diving deep into those pores. Alcohol-based products only amplify this effect. Together, they might leave your skin feeling like the Sahara.
  • Staying Quenched: Always check your product ingredients. If alcohol is hanging around the top of the list, it's a major player. Save these products for days when salicylic acid isn't on the roster, and always follow up with a rich moisturizer.

The Radiance Reducer: Hydroquinone

Hydroquinone is a big name when it comes to skin lightening, but paired with salicylic acid? Not the dream team you'd expect.

  • The Science: Hydroquinone works hard to inhibit melanin production. Now, when you bring salicylic acid into the picture, the skin's sensitivity to the sun can increase, potentially leading to unintended hyperpigmentation, which is ironic since you're using hydroquinone to decrease it!
  • Smart Moves: If you're keen on both ingredients, alternate their usage. And we can't stress this enough – sunscreen should be your best buddy! Especially when playing with ingredients that sensitize your skin to the sun.

The Barrier Busters: Peptides

Peptides in skincare? Absolutely! They're fantastic for anti-aging.

But there's a but...

  • The Science: Peptides are the building blocks of proteins, like collagen, in the skin. While they're fantastic for keeping skin youthful, the low pH of salicylic acid might break them down, making them less effective.
  • The Plan: Use peptides in your AM routine and salicylic acid in your PM. Giving them separate slots ensures you get the best bang for your buck from both.

The Protective Shield Strippers: Physical Exfoliants

Got those scrubs with gritty bits?

That's physical exfoliation, and here's the tea on why it's not BFFs with salicylic acid.

  • The Science: Salicylic acid is already working overtime, exfoliating your skin from the inside out. Pair it with a physical exfoliant, and you might overdo it, leading to redness, irritation, and sensitivity.
  • Balancing Act: If you're a fan of that scrubby sensation, opt to use these on days you're giving salicylic acid a rest. Moderation is key.

Go Forth and Glow!

In the bustling world of skincare, it's all about making informed choices.

Azelaic acid and salicylic acid can be a winning team, but the key is understanding how to use them correctly.

By respecting your skin's needs and introducing them properly, this dynamic duo might just be the answer you've been searching for.

Bottom Line: Your skin is unique, and what works for one person might not work for another. Experiment, be patient, and always listen to your skin.

Because at the end of the day, it's all about feeling confident and radiant in your skin. And we’re here with you every step of the way!
