How to use azelaic acid: serum, pad or spot cream, and what to pair it with
Updated October 22, 2026
Apply azelaic acid after cleansing and toner, on dry skin, and follow it with moisturizer; if you use it in the morning, sunscreen goes on last. Start with one or two uses a week and build toward daily only while your skin stays comfortable, choosing a 10% serum for the whole face, a pad you leave on as a 10 to 20 minute mini mask, or a spot cream for single blemishes.
For a first azelaic acid, we'd start with the Anua Azelaic Hyaluron Soothing Serum, 30 ml: it is 10% azelaic acid, fragrance-free, $15.99 at Sleepy Hello (checked October 2026), and its directions spell out the slowest, clearest start of the three serums we stock.
This is a researched guide built from current US brand and retailer information, checked October 2026. We haven't worn or tested these products; texture descriptions are the brands' own, and the advice comes from comparing formulas, directions, sizes and prices. If a clinician has given you a plan for your skin, follow that first.
How do you use azelaic acid in a skincare routine?
Use it as a leave-on serum step between toner and moisturizer. The three Korean serums here use 10% azelaic acid for the look of redness, blemishes, excess oil and uneven tone. The routine is the same for all three:
Cleanse gently and pat your face dry.
Use a hydrating toner if you have one, not an exfoliating one. All three brands place their serum after toner.
Let your skin dry. Anua allows dry or slightly damp skin but says to begin on dry skin if you are sensitive or new to azelaic acid. Medicube and Centellian24 both say clean, dry skin.
Apply a small amount. Anua starts at 1 to 2 drops, Medicube says 2 to 3 drops for the face and neck, and Centellian24 says a few drops, focusing on areas of concern. Pat it in, away from eyes and lips, and let it absorb.
Moisturize. Anua and Medicube both say to follow with moisturizer.
Finish with sunscreen in the morning. Anua asks for SPF 30 or higher when you use its serum during the day, and Medicube says to finish with sunscreen.
Can you use azelaic acid every day?
Yes, once your skin has adjusted, though we wouldn't start daily. Anua's directions begin at one or two uses a week and allow a gradual increase, up to 5 drops per use and as often as twice daily. Medicube's directions are morning and evening from the start, with every other day for more sensitive skin.
Centellian24 and Mary&May don't publish a frequency. We'd use a slower ramp for any of the serums:
Weeks one and two: two evenings a week, with plain moisturizing nights in between.
Weeks three and four: every other evening.
After that: nightly, or morning and evening where the brand's directions allow it and your skin still feels normal.
Burning, swelling, a rash or redness that lasts into the next day are reasons to stop. Rinse it off, go back to your plain routine, and get medical advice if a reaction doesn't settle.
Anua's pad is the exception: the brand says to use it daily, morning or evening.
Serum, pad or spot cream: the azelaic acid products we stock
The three serums share 10% azelaic acid and the same routine slot; what differs is the rest of the formula and the price.
Anua serum: the simplest start
Anua's serum lists water, azelaic acid, propylene glycol, sodium hydroxide (which adjusts pH), dipropylene glycol, 1,2-hexanediol, panthenol, hydroxyethylcellulose and betaine salicylate (a gentle BHA) first, with niacinamide, zinc PCA, centella and ceramide NP further down. Anua says it is fragrance-free and designed with oily and sensitive skin in mind, and describes a lightweight, fresh texture that can feel slightly tacky. It is $15.99 for 30 ml, about 53 cents per ml.
Medicube serum: for pores and rough texture
The Medicube Azelaic Acid 10 BB Soothing Serum opens with water, butylene glycol, azelaic acid, propanediol, sodium hydroxide, propylene glycol, 1,2-hexanediol and niacinamide. Medicube positions it for visible pores, rough texture and post-blemish marks, with a non-sticky finish. The ingredient list also includes lavender oil, linalool and denatured alcohol. It is $22.99 for 30 ml, about 77 cents per ml.
Centellian24 serum: the multi-acid option
The Centellian24 Madeca Azelaic Acid 10+ Calming Serum starts with water, propylene glycol, azelaic acid, sodium hydroxide, niacinamide, pentylene glycol, succinic acid, gluconolactone (a PHA), erythritol and xylitol, and later adds zinc PCA, salicylic acid, lactic acid and phytic acid. Centellian24 calls this a multi-acid blend for blemishes, texture, oil and pores, with a cooling feel, and says it is designed with sensitive and blemish-prone skin in mind. Because it combines several acids, though, we'd keep it for people already comfortable with exfoliating acids. It is $28.99 for 30 ml, about 97 cents per ml.
Anua pad: hydration first
The Anua Azelaic 10 Hyaluron Redness Soothing Pads are a toner pad that Anua says doubles as a mini mask for redness caused by dryness. Place a pad on the area for 10 to 20 minutes, remove it, then wipe it across your face. The ingredient list leads with water, butylene glycol, dipropylene glycol, propanediol, glycerin and betaine; azelaic acid sits 27th of 51 ingredients, after xanthan gum, disodium EDTA and the first two hyaluronic acid forms, and no percentage is given. Think of it as a hydrating pad with some azelaic acid, not a pad version of the serum. It is $15.99 for 90 pads (230 ml), about 18 cents a pad.
Mary&May spot cream: for single blemishes
The Mary&May Spicule Azelaic PDRN Spot Cream pairs 2% azelaic acid with 3,000 ppm marine-derived micro spicules (microscopic sponge-derived spicules that the product page says create a noticeable, stimulating feel), 5% niacinamide, CICA PDRN, 3,000 ppm zinc PCA and 1% panthenol, according to Mary&May. The ingredient list also includes salicylic acid, tea tree leaf oil and limonene. The only direction is to massage in a moderate amount, with no frequency, so we'd dot it on individual spots and keep it off broken skin. It is $10.99 for 15 g.
For the morning: sunscreen
If azelaic acid goes into your morning routine, finish with a sunscreen such as Beauty of Joseon Relief Sun: Rice + Probiotics SPF50+ PA++++, $12.99 for 50 ml. Beauty of Joseon says to apply it generously as the last step and reapply at least every two hours; newer tubes say Rice + Niacinamide, same formula.
Can you use azelaic acid with niacinamide or vitamin C?
Yes to both: niacinamide is already in all three serums' ingredient lists, and vitamin C pairs best in the morning with azelaic acid at night while you start. The Mary&May cream also lists 5% niacinamide, so a separate niacinamide serum is optional.
If you want one, the Anua Niacinamide 10% + TXA 4% Dark Spot Correcting Serum ($23.99 for 30 ml) lists 10% niacinamide, 4% tranexamic acid and 2% arbutin, and its ingredient list also includes betaine salicylate and a vitamin C derivative, 3-O-ethyl ascorbic acid. The simplest pairing is one serum in the morning and the other at night; our Anua azelaic acid vs niacinamide serum comparison covers which to pick if you only want one.
With vitamin C, the reason to split them at first is practical: starting two actives at once makes it hard to tell which one your skin disliked. Once both feel routine, you can layer them, letting each absorb first.
Can you use azelaic acid with retinol?
Yes, but not on the same night while you are starting either one. None of the product pages here gives a retinol rule, so separate them: azelaic acid in the morning under sunscreen and retinol at night, or alternate evenings. Add one new product at a time and give it two to four weeks before adding the next. If your retinoid is a prescription, ask the prescriber before adding azelaic acid.
The same caution applies to exfoliating acids. Anua's serum contains betaine salicylate; Centellian24's lists salicylic acid, gluconolactone and lactic acid; Mary&May's lists salicylic acid plus spicules. On nights you use one of these, skip a separate AHA or BHA toner, peeling gel or exfoliating pad.
Common mistakes with azelaic acid
Using more to speed things up. A thicker layer adds irritation risk, not speed.
Stacking exfoliants. An azelaic serum, an acid toner and a peeling gel on one night are three acid steps.
Skipping sunscreen. If the serum goes on in the morning, SPF goes on last.
Judging it after a week. Anua and Centellian24 both publish their own results as four-week measurements, a sensible minimum before you decide.
Quick answers
Do you apply azelaic acid before or after moisturizer?
Before. Azelaic acid is a serum step: toner, then azelaic acid on dry skin, then moisturizer, then sunscreen in the morning. Anua and Medicube both print this order.
Is azelaic acid better in the morning or at night?
Either works; Anua and Medicube allow both. We'd start at night, which keeps it away from morning vitamin C and makeup. If you use retinol at night, move azelaic acid to the morning and finish with SPF.
What does azelaic acid do?
In the brands' words, it helps with the look of redness, blemishes and excess oil (Anua), visible pores, rough texture and post-blemish marks (Medicube), and blemishes, uneven texture and oil (Centellian24).
Is azelaic acid good for sensitive skin?
Anua, Medicube and Centellian24 all say their serums suit sensitive skin. Anua's fragrance-free serum is the one we'd start with, since Medicube's lists lavender oil and Centellian24's combines several exfoliating acids. Begin on dry skin, two evenings a week; our guide to Korean skincare for sensitive skin covers the rest of a gentle routine.
