Can you use azelaic acid with retinol?

Yes. Azelaic acid and retinol can be used in the same routine. Studies have paired azelaic acid with tretinoin, a prescription retinoid, and a 2024 trial tested a routine of azelaic acid, salicylic acid and retinol that worked close to as well as a benzoyl peroxide routine, with fewer people quitting. No label Skinli read forbids the pair. Skinli's own plan keeps them at different times of day: azelaic acid in the morning and the retinoid adapalene at night. If either product is a prescription, ask the doctor or pharmacist who gave it before you combine them. This page is part of Skinli's guide to which skincare ingredients you can mix.

Why people pair azelaic acid with a retinoid

Both ingredients have a place in acne care. The 2024 acne guideline from the American Academy of Dermatology (AAD) gives topical azelaic acid what it calls a conditional recommendation, the same rating it gives salicylic acid. The same guideline says that "common treatments for acne-induced hyperpigmentation include topical retinoids, azelaic acid, hydroquinone, and physical modalities such as lasers and chemical peels." Hyperpigmentation means patches of skin that are darker than the skin around them, such as the flat marks pimples leave.

A 2025 study in the Journal of the American Academy of Dermatology asked 62 dermatologists at 43 centers to vote on skincare ingredients in two rounds. They agreed on azelaic acid for acne and dark spots, and on retinoids for acne, dark spots, fine lines and wrinkles, large pores and oily skin. The study lists each ingredient on its own and gives no rule for combining them.

NICE, the body that writes acne guidance for the NHS, gives azelaic acid a special role. Its rationale calls topical azelaic acid, combined with a tetracycline antibiotic taken by mouth, "a good alternative for people who have irritation to topical retinoids, since all other options for moderate to severe acne contain a topical retinoid." For keeping acne away after it clears, NICE says "topical adapalene, topical azelaic acid or topical benzoyl peroxide could be used."

A 2026 review of skincare ingredients in acne adds that "cosmeceuticals such as retinol, niacinamide and azelaic acid may be most beneficial for patients with mild-to-moderate acne, sensitive skin or those unable to tolerate prescription treatments." Cosmeceuticals are skincare products with active ingredients, sold without a prescription.

What the studies tested

Three sources describe azelaic acid used with a retinoid.

Study	What was used	What it reported
2000 paper, Journal of the American Academy of Dermatology	Azelaic acid with benzoyl peroxide 4% gel, clindamycin 1% gel, tretinoin 0.025% cream, or erythromycin 3% with benzoyl peroxide 5% gel	Azelaic acid worked better, and patients rated it higher overall, in combination
2020 case series, Case Reports in Dermatological Medicine	Tretinoin lotion 0.05% with azelaic acid 15% foam	Four African-American women with chest and back acne were successfully treated
2024 split-face trial, Archives of Dermatological Research	A 3-step routine of azelaic acid, salicylic acid and retinol, against a 3-step benzoyl peroxide routine	Lesions fell by 36% with the azelaic acid routine and 40% with benzoyl peroxide by week 12

The 2024 trial needs a closer look, because it is the only one that used retinol. In a split-face trial, each person uses one routine on each half of the face. The trial recruited 37 adults with mild to moderate acne. Of those, 21 took a 2-week break from other acne products and completed the study. Three dropped out because of irritation from the benzoyl peroxide routine, and 13 were lost to follow-up, which means the researchers could not reach them later. The retinol was "graduated," which means its strength went up in steps.

Users of the azelaic acid routine reported less redness, itching and burning, though the authors say the differences were small enough that they could be due to chance. The authors concluded that the routine gave similar lesion reduction, fewer dropouts, better tolerability and a higher preference among users than the benzoyl peroxide routine.

These are small studies. A case series of four people cannot show how most people will respond. The 2024 routine also held salicylic acid, which prescription retinoid labels warn about. Skinli's page on salicylic acid with retinol covers that pair.

What the labels say

The prescription Azelex label, for azelaic acid cream 20 percent, has no drug interaction section. It gives no instruction about using azelaic acid with a retinoid. It does warn about stinging: "Due in part to the low pH of azelaic acid, temporary skin irritation (pruritus, burning, or stinging) may occur when AZELEX® cream is applied to broken or inflamed skin, usually at the start of treatment." Pruritus means itching. A low pH means the product is acidic.

MedlinePlus, on azelaic acid, says to wash the skin with water and a mild soap or soapless cleansing lotion, pat it dry, and avoid alcoholic cleansers, tinctures, abrasives, astringents and peeling agents, especially if you have rosacea.

The retinoid labels are stricter about other products:

• An NHS hospital leaflet on adapalene says to avoid peeling agents like salicylic acid or glycolic acid while using it. Azelaic acid is absent from that list.
• The over-the-counter Differin label says irritation is more likely if you use more than one topical acne medication at a time.
• The Retin-A label says other topical medication used at the same time should be used with caution because of possible interaction with tretinoin, and it says: "Do not use other medications with RETIN-A which are not recommended by your doctor."
• MedlinePlus says people using tretinoin should use no other topical medications unless the doctor directs it.

Some azelaic acid products, such as the 20 percent cream, need a prescription. If your azelaic acid or your retinoid came from a doctor, ask that doctor or your pharmacist before you add the other.

How Skinli's plan uses the pair

Skinli's 12-week plan adds azelaic acid for people whose pimples leave flat marks. From week 5, the plan puts azelaic acid 10 percent on in the morning, before sunscreen. The acne gels, adapalene 0.1 percent and benzoyl peroxide 2.5 percent, stay at night. So the retinoid and azelaic acid never go on at the same time.

That timing follows the AAD's advice on retinoids. A dermatologist quoted by the AAD advises using a retinoid only at night, because retinoids can make skin more sensitive to sun, and always using sun protection during the day. Skinli's guide to starting adapalene covers the night routine in detail.

How to start the pair

If you want to use azelaic acid with retinol or adapalene, the sources support these steps:

1. Add one product at a time. Start the retinoid first, or keep the one you already use, and add the second later. If both start at once and your skin reacts, you cannot tell which one caused it.
2. Patch test the new product. The AAD says to apply it to a test spot twice a day for 7 to 10 days, and to go ahead if you have no red, itchy or swollen skin. Skinli's guide to patch testing explains how.
3. Keep the retinoid at night. Start every other night with the least-intense formula you can find, as the AAD advises.
4. Put azelaic acid on at another time. Skinli's plan uses the morning.
5. Expect some stinging at first. The Azelex label says it is usually temporary and happens at the start of treatment.
6. Moisturize. The AAD says a daily moisturizer can help skin tolerate adapalene, tazarotene or tretinoin. Look for "non-comedogenic" or "won't clog pores" on the label.
7. Use sunscreen every day.

The AAD's page on dark spots gives a limit: "If a product burns or stings when you apply it, stop using it." If the stinging from azelaic acid does not settle after the first days, stop and ask a doctor or pharmacist.

Azelaic acid and a retinoid for dark marks

The AAD's page on fading dark spots in darker skin tones lists both ingredients among those to look for: "Azelaic acid" and "Retinoid (retinol, tretinoin, adapalene gel, or tazarotene)." It says to use a product that contains one of them, and that "a dermatologist has the knowledge and expertise to safely combine treatments to help you get the best results."

Irritation matters more in darker skin. The AAD says that "with skin of color, irritation can trigger dark marks." Starting each product slowly lowers the chance of new marks while you treat the old ones. Skinli's guide to fading dark marks after pimples covers the other options, and its guide to what to mix with a retinoid covers other products people add.

When to ask a doctor

Give the routine time. The AAD says it takes at least 6 to 8 weeks to start to see fewer breakouts, and Skinli's plan allows 8 to 12 weeks for skin to change. See a doctor if acne is painful, forms deep lumps, leaves scars, changes fast, or has not improved after steady care. If a retinoid irritates your skin too much, a doctor can talk to you about options such as the azelaic acid treatment NICE describes. Never stop a prescribed treatment without asking the doctor who gave it.
