Azelaic Acid
INCI: Azelaic Acid
Evens toneCalms rednessRefines blemish-prone skin
A rare multi-tasker that addresses uneven tone, redness and blemish-prone skin at once, and is gentle enough for sensitive, reactive complexions.
What it is
Azelaic acid is a dicarboxylic acid found naturally in grains like wheat and barley. Despite the name it is not an exfoliating acid in the AHA or BHA sense. It is a gentle, versatile active with an unusual breadth of benefits, which is why it has a devoted following among people whose skin struggles with several concerns at once.
How it works
Evens tone
It helps interrupt excess pigment production, supporting a more even, brighter-looking complexion, and is often chosen for post-blemish marks.
Calms redness and blemishes
It has a soothing, clarifying quality that helps reduce the look of redness and suits congested, blemish-prone skin, all with a gentle profile.
The evidence
Azelaic acid has strong published support across tone, redness and blemish-prone skin, and is well regarded for combining genuine efficacy with unusually good tolerability, including on sensitive skin.
Worth knowing
Higher-strength azelaic acid is available as a medical treatment. In cosmetic skincare it supports the look of even, calm, clear skin. Persistent redness conditions like rosacea deserve a dermatologist.
