Adding azelaic acid to your routine can help with all sorts of complexion issues, from acne to rosacea to hyperpigmentation. But how easily can this gentle exfoliating acid fit into your skin care stack and does it play well with other ingredients? Read on to find out.
Key Takeaways
- Azelaic acid is a gentle multitasking ingredient that helps reduce acne, redness and hyperpigmentation while pairing well with many popular skin care actives.
- Azelaic acid and vitamin C create a brightening duo that helps reduce the appearance of dark spots and uneven skin tone on acne-prone skin
- Pairing azelaic acid with niacinamide can help calm redness, strengthen the skin barrier, regulate oil production and improve overall skin texture.
- Azelaic acid works well with salicylic acid and lactic acid, but timing and gradual use are key to avoiding irritation and over-exfoliation.
Can You Mix Azelaic Acid With Other Ingredients?
Over-the-counter azelaic acid is generally well-tolerated and pairs beautifully with many popular active ingredients, but the order and timing of the application is the biggest consideration. Here’s a quick cheat sheet:
Azelaic Acid & Vitamin C
Vitamin C is notoriously finicky. Pair it with the wrong ingredients and things can go sideways fast. Benzoyl peroxide will deactivate it completely. Retinol can cause redness and peeling. AHAs like lactic acid and BHAs like salicylic acid trigger over-exfoliation. But azelaic acid? It plays nicely with vitamin C. No deactivation. No irritation.
This duo forms a powerful brightening combination that helps visibly reduce the appearance of dark spots, redness and uneven skin tone. Together, they help improve the look of dark spots and the feel of skin texture.
How To Use Them
You can layer the two ingredients in the same routine. Start with the thinner product first (usually vitamin C) and allow it to absorb for 1–2 minutes before applying your azelaic acid. If you’re applying them together in the morning, always follow with SPF, as both vitamin C and azelaic acid make your skin more sensitive to the sun.
The split AM/PM routine is perhaps the most ideal recipe for this duo. Use vitamin C in the morning to protect against free radical damage (especially when worn with your SPF) and then apply the azelaic acid at night to calm the look of redness and help treat breakouts.
Azelaic Acid & Niacinamide
Niacinamide is a topical version of vitamin B3 used as an active ingredient in many products. It can help lock in hydration, minimize large pores, improve the look of uneven skin tone, soften the appearance of fine lines, brighten skin and regulate oil production.
Since azelaic acid can sometimes cause mild tingling or dryness, niacinamide can offset this sensitivity because it is deeply soothing and hydrating. Together they calm the look of redness, fade the look of dark spots and help in the fight against acne.
How To Use Them
To layer this duo, apply your niacinamide product first (usually a lighter, water-based serum) and allow it to absorb. Then add your azelaic acid on top. Because both have antioxidant and anti-inflammatory properties, they make a great protective pairing under your daily SPF.
If skin is sensitive, try the AM/PM method. Split the two ingredients and use the niacinamide in the morning and the azelaic acid in your nighttime routine.
Azelaic Acid & Salicylic Acid
These two acids perform different functions but work very well with each other. Salicylic acid is oil-soluble, meaning it penetrates deep into the pore to break down the blockage at its source, making it effective for blackheads. Azelaic acid works closer to the skin's surface, focusing on bacteria, environmental debris, inflammation and cell turnover. Basically, this combo is a one-two punch when treating acne.
How To Use Them
As with many of these duos, timing is everything. Using these two acids together can put the skin at risk of over-exfoliation, so splitting them between your AM and PM routines is recommended. Applying the salicylic acid in the morning to dissolve that oil clogging your pores and using the azelaic acid at night to brighten tone and reduce redness while you sleep is the best way to combine these two ingredients.
If your skin is really sensitive, try alternating days. The risk of over-exfoliation is magnified if you do too much. Make a schedule and stick to it, at least in the beginning. The PM/PM method gives your skin time to recover. Apply your salicylic acid in the evening on day 1 and then your azelaic acid the following night. Continue to alternate nights until you notice that your skin is adapting. In other words, if there’s no redness or flaking, you have the all-clear to try upping the frequency.
A third option is the wash-off method, which is the simplest of them all. To combine more ingredients without risking over-stripping the skin, try using a salicylic acid cleanser like the Acne Advanced Cleansing Foam and then rinse it off thoroughly before applying your azelaic acid product and leaving it on.
Azelaic Acid & Lactic Acid
Lactic acid is an alpha hydroxy acid (AHA) that improves skin’s texture and hydration by dissolving the top layer of dead skin. Like azelaic acid, it is a skin-brightening and exfoliating ingredient. Lactic acid and all AHAs can increase sun sensitivity, so it's best to use them only at night. And if you’re introducing lactic acid for the first time, start slow, just 2–3 evenings a week.
How To Use Them
A morning and night routine is also recommended for these two ingredients. As mentioned, lactic acid should be used at night, which leaves the morning slot open for azelaic acid.
Another option is alternating nights. Sticking to just an evening skin routine could make it easier to remember (though an alert in your phone or a little memo stuck to your bathroom mirror can help you stay on schedule). Again, this gives the skin a little room between applications and helps avoid, or at least minimize, potential irritation.
If you have strong, resilient skin, the two products can be layered at night. Apply lactic acid first and let it dry for a couple of minutes before using your azelaic acid. But a word of caution, this is not for beginners, as it can cause redness and peeling if your skin isn’t used to it.
Our Clear Skin Willow Bark Exfoliating Peel contains both salicylic and azelaic acids, plus lactic acid and fruit acids. All are gentle and work well together, leaving skin clear, smooth and revitalized. In other words, this is the one-and-done multitasking product. Rather than adding another step to your routine, try this deep cleansing, clarifying peel that removes impurities, helps balance sebum and reduces the appearance of pore size, redness and irritation.
And one more note, if you’re using prescription azelaic acid, we would suggest having a conversation with your physician or dermatologist to determine what products would be suitable to use in conjunction with the prescribed azelaic acid product.
