How Azelaic Acid Works
How Azelaic Acid Works — a naturally occurring dicarboxylic acid that works through several pathways at once, calming inflammation, normalizing the shedding of cells that clog pores, and gently interrupting excess pigment production. It is valued because a single ingredient can address acne, redness, and uneven tone with relatively low irritation.
Key points
- It has antimicrobial activity against Cutibacterium acnes, the bacteria involved in acne breakouts.
- It normalizes keratinization, reducing the buildup of dead cells that block follicles and form comedones.
- It inhibits the enzyme tyrosinase, which helps fade post-inflammatory hyperpigmentation and other dark marks.
- Its anti-inflammatory and antioxidant effects make it useful for the redness and bumps associated with rosacea.
Frequently asked
Is azelaic acid an exfoliating acid like glycolic or salicylic acid?
No, despite the name it is not a traditional chemical exfoliant; it works mainly by normalizing cell turnover, reducing bacteria, and calming inflammation rather than dissolving surface bonds between cells.
Can azelaic acid be used with other active ingredients?
It generally layers well with ingredients like niacinamide and most routines, though combining multiple potent actives can increase irritation, so introducing one new product at a time is sensible.
