Azelaic acid
Also listed as Nonanedioic acid and Potassium azeloyl diglycinate (derivative)
Azelaic acid is a naturally occurring acid (produced by a skin yeast and found in grains) used for breakouts, redness-prone skin and uneven tone. Higher strengths are prescription medicines; lower strengths appear in cosmetics.
What it does
The short version.
Azelaic acid reduces acne bacteria, normalizes how skin cells shed inside pores, calms inflammation and selectively inhibits tyrosinase in overactive pigment cells. That combination makes it useful for bumps, post-blemish marks and visible redness. It is considered compatible with pregnancy by many dermatologists, which makes it a common alternative to retinoids.
Strong evidence
Prescription 15% and 20% formulations are supported by randomized controlled trials for acne and rosacea and are included in AAD acne guidelines. Over-the-counter cosmetic products use lower concentrations (often around 10%) that have less direct trial data.

Before you start
Tingling, itching or burning is common for the first couple of weeks and usually settles. Rarely it can lighten skin in people with darker skin tones. Redness that persists or flushes easily may be rosacea, which a dermatologist should diagnose.
