What it is & what it does
Azelaic acid is a dicarboxylic acid with well-established dermatologic activity for acne, redness-prone skin and uneven pigmentation.
WHAT IT IS: Azelaic acid is a dicarboxylic acid used in dermatology and cosmetic skincare for blemish-prone skin, redness-related concerns and uneven pigmentation.
WHAT THE SCIENCE SUPPORTS: Unlike a conventional AHA peel, its relevant actions include effects on abnormal keratinization, inflammation and pigment-related pathways. Clinical evidence is especially meaningful for appropriately formulated topical azelaic-acid products, but an ingredient appearing at an unknown percentage does not establish a prescription-strength result.
IN A SKINCARE ROUTINE: Daily use and tolerance depend on concentration and vehicle; an azelaic-acid product may suit routines that also target post-blemish marks, with gradual introduction when skin is reactive. Claims for one ingredient should not be presented as a proven result for every finished product.
