What is Azelaic Acid?
Azelaic acid is a gentle multitasking ingredient that calms redness, clears blemishes and fades dark spots. It is one of the few actives suited to rosacea-prone and acne-prone skin at the same time, and it is gentle enough for sensitive skin. Over-the-counter formulas are usually 10%; higher strengths are prescription.
How Azelaic Acid works
Azelaic acid has anti-inflammatory and gentle antibacterial effects that calm redness and blemishes, while also interrupting excess pigment to fade dark spots and post-acne marks. It works with less irritation than many acids, which is why sensitive and rosacea-prone skin tolerate it well.

Azelaic Acid vs other ingredients
Both calm redness and even tone gently. Azelaic also clears blemishes and fades pigment more actively; niacinamide also controls oil. They pair very well together.
Both fade dark spots. Vitamin C also brightens and adds antioxidant defence but can sting; azelaic is gentler and also calms redness and blemishes - a better pick for reactive or rosacea-prone skin.
Benzoyl peroxide is a stronger acne-fighter but can be drying and irritating. Azelaic is gentler and also fades marks and calms redness - better for sensitive, rosacea-prone skin.
How to use Azelaic Acid
Apply a thin layer of azelaic acid to clean skin, once or twice daily. It can be used morning or night and layers under moisturiser and SPF. A mild tingle at first is normal; give it a few weeks. Follow daytime use with SPF.

Side effects & safety
Azelaic acid is generally well tolerated. A mild, temporary tingle or itch when starting is normal; if it persists or irritates, reduce frequency. Patch test new products. Higher-strength prescription versions should be used under medical guidance. General information, not medical advice.
