Azelaic Acid — What It Does & How to Use It

What does Azelaic Acid do?#

A multi-benefit leave-on formula with azelaic acid that helps improve the appearance of redness, uneven skin tone, and breakout-prone skin.

Helps reduce the visible appearance of redness
Supports a more even, balanced-looking skin tone
Helps improve the appearance of breakout-prone skin
Suitable for a wide range of skin tones

How it works

Azelaic acid is a naturally occurring compound found in grains like rye, wheat and barley. It works on multiple visible concerns at once — helping to improve the look of redness, uneven tone, and breakout-prone skin for a clearer, calmer-looking complexion.

What to expect

Expect mild tingling on application during the first few weeks — it usually settles as your skin adjusts. Azelaic acid isn't known to cause an initial breakout period. Any change in the look of redness and tone tends to be gradual, so give it several weeks before judging. It is best known for the look of redness that comes with blemishes and bumps, rather than for visible facial veins.

How to use Azelaic Acid#

Morning or evening, after cleansing and before moisturizer. Twice a day is the usual pattern; once a day is usually the evening.
On clean, dry skin. Use a mild or soap-free cleanser first and pat dry.
Across the whole face, not dabbed on individual spots — but keep it away from the eyes and lips. Rinse with plenty of water if any gets in your eyes.
Daily from the start is fine. Unlike stronger actives, it does not need weeks of easing in.
If it stings more than you would like, use less or drop to every other evening until it settles.
Leave it uncovered — do not seal it under a pimple patch or any airtight cover.
Keep it to a different evening from exfoliating acids, scrubs and alcohol-based toners, which can make the tingling sharper.
Let it dry before makeup, and wash your hands afterwards.
Mild tingling or warmth is normal when first starting — this typically fades over the first few weeks.

Mild stinging or tingling may occur during initial use. Discontinue use if persistent irritation occurs, or if any area starts to look lighter than the skin around it.

What not to use with Azelaic Acid

Exfoliants

Different times

Both are active on the skin’s surface and combining them can increase the chance of irritation.

Glycolic Acid (AHA) · Lactic Acid (AHA) · LHA · Mandelic Acid (AHA) · Salicylic Acid (BHA)

Eye-area retinol

Different times

Azelaic acid goes all over while the eye cream stays around the eyes — keep them to separate evenings so the eye area has time to settle.

Who should avoid Azelaic Acid?#

Six situations change whether Azelaic Acid suits your skin right now. Each one is either a reason to skip it, a reason to go slowly, or nothing to watch for.

Fragile or Sensitive: Skip it
Recent Facial or Laser: Skip it
Maternity & Nursing: Go slowly
Dry or Itchy Patches: Go slowly
Recent Shave or Wax: Go slowly
Prone to Redness: No caution

Maternity & Nursing — If you are pregnant or nursing, you may prefer to check with your healthcare provider before use.

Dry or Itchy Patches — Keep the rest of your routine well moisturized, and use it less often — or stop — if you notice tightness or itching.

Recent Shave or Wax — Avoid for 24 hours after waxing, threading, or dermaplaning.

Cosmetic strength limits for Azelaic Acid where you live#

Region	Maximum strength
United States	No explicit cap
Canada	14%
European Union	No explicit cap
Great Britain	No explicit cap

Where a figure appears, that is the maximum strength allowed or advised for azelaic acid in that market — some are set in cosmetics regulation, others are the ceiling a cosmetic safety panel recommends. The rest set no maximum. Either way these are limits, not targets — the right strength for a formula is the formulator's decision. Some products containing this ingredient at higher strengths are prescription medicines, not cosmetics.

Everything on this page traces to the sources listed below — regulators' own publications and published studies. Where the evidence does not answer a question, it is left unanswered.

Some sources below are the official product information for prescription medicines — some contain this ingredient at higher strengths, others are cited for how they interact with it. We use them for their safety and handling detail only. A cosmetic product is not one of those medicines and is not intended to treat any condition.
