Azelaic acid doesn't get as much attention as vitamin C or retinol, but it quietly does a lot. It clears breakouts, calms redness and fades dark spots without the irritation those other ingredients can cause. If you've been curious about adding it to your routine, here's how to actually use it.
Key Takeaways
- Azelaic acid is a gentle multitasking ingredient that helps improve acne, redness, rosacea, hyperpigmentation and uneven skin texture.
- You can use azelaic acid in the morning or evening, but the best timing depends on the other active ingredients in your routine.
- Start slowly with azelaic acid 2–3 times per week, then gradually increase use as your skin adjusts to avoid irritation.
- Azelaic acid works with ingredients like vitamin C, hyaluronic acid and salicylic acid.
- Consistency is key — regular use of azelaic acid can improve skin clarity, smoothness and dark spots over time.
When To Use Azelaic Acid: AM vs. PM
Azelaic acid can be used in the morning or evening. It layers well with other products and is gentle enough to use every day. Most people prefer to use it at night, especially if they’re layering it with other actives, but it really comes down to personal choice and the rest of your skin care routine.
How Often To Use Azelaic Acid
A gradual introduction (think: 2–3 times per week) will both allow you to mitigate any reactions and let you monitor your skin’s comfort level. Listen to your skin. If you feel any stinging, tightness or increased redness, pull back on the frequency while it adapts.
Once any side effects have calmed down, introduce one more day per week until you work your way up to once a day. And be patient. When you hit the daily application schedule, it can be 4–6 weeks before you see improvements in skin texture, acne and pigmentation issues, and up to 6 months of regular use to see maximum results.
How To Apply Azelaic Acid: A Step‑By‑ Step Guide
Step 1
Start by cleansing the skin with your usual cleanser. Now is not the time to switch anything else up. Keep the rest of your routine the same while introducing azelaic acid. This applies to any new products you introduce. When more than one variable is changed, it’s hard to know what to attribute any changes (good or bad) to. Stick to one new thing at a time.
Step 2
Let skin dry or leave it slightly damp and add a hydrating toner. Applying a hydration product on damp skin can help it absorb better because the skin is more permeable, allowing ingredients to penetrate deeper.
Step 3 (Optional)
If you use a serum, now is the time to apply a light layer. But be cautious as some serums that contain active ingredients like exfoliating acids (AHAs, BHAs) or retinoids can cause irritation or over-exfoliation. Stick to hydrating serums like something with hyaluronic acid. Our Strawberry Rhubarb Hyaluronic Serum is a great option here. If you want to use a vitamin C serum, make sure to allow it to dry for a few minutes before applying your azelaic acid.
Step 4
Apply azelaic acid as a thin, even layer. Use a pea-sized amount or swipe a cotton pad all over the face, depending on the formulation of azelaic acid you are using. You can also spot treat specific areas (breakout-prone or hyperpigmented marks) rather than treat your whole face if you prefer. Allow the product to dry for about 2 minutes before applying your moisturizer.
Step 5
Lock it in with a moisturizer. Azelaic acid clears the pores, helping to prevent future blemishes and improve the appearance of existing spots. It also increases cell turnover. Since this can cause some dryness and flaking, it’s important to combine it with complementary ingredients that will keep the skin hydrated.
If you’re applying your azelaic acid in the morning, always follow that with an SPF. That’s a non-negotiable anyway, but because azelaic acid can make your skin a bit more sensitive, it’s always recommended.
Should Anything Not Be Mixed With Azelaic Acid?
Because it’s so gentle, azelaic acid pairs easily with other active ingredients. The order and timing of the application is the bigger consideration than what it can or can’t be mixed with. Here’s a quick cheat sheet:
Vitamin C: It’s safe to use azelaic acid and vitamin C together. Both help with the look of dark spots and smooth the skin. The two of them are also suitable for acne-prone complexions. Apply our Citrus & Kale C+E Serum after your hydrating toner and let it dry for a few minutes before your next step.
Retinol: Both have an exfoliating effect, though azelaic acid is much more gentle. They complement one another but should be applied at different times of day. Retinol should always be used in the evening, so make sure azelaic acid is used in the morning if you’re doubling up. To be really safe, you could use them on alternating days.
Hyaluronic Acid: This combo is a dream team for your skin. While azelaic acid is exfoliating and helping to encourage cell turnover, hyaluronic acid helps retain water in the skin, plumping it and even helping increase skin barrier function.
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.
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 multitasking product you need in your life. 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.
