Comparison
The Ordinary Azelaic Acid vs Paula's Choice Booster
Two 10% azelaic acid options often compared for post-acne marks and uneven tone — a budget suspension vs a booster serum with supporting ingredients.
Quick verdict
The Ordinary's suspension is the simpler, lower-cost entry point: straight 10% azelaic acid in a cream-gel base. Paula's Choice adds its booster format with azelaic acid alongside supporting ingredients and a serum-like feel. Choose The Ordinary for a minimal formula and price; choose Paula's Choice if you prefer a lighter serum texture and a more blended supporting formula.

Detailed comparison
The Ordinary Azelaic Acid Suspension 10% is a direct, affordable way to try azelaic acid. Azelaic acid is often discussed for post-acne marks, uneven tone and sensitive acne-prone skin. The suspension texture can pill under some moisturisers or makeup — many people use it in the evening.
Paula's Choice 10% Azelaic Acid Booster is a leave-on serum-style product that pairs azelaic acid with other supporting ingredients. It is often compared when someone wants azelaic acid but prefers a fluid booster over a suspension.
Both are available in the UK and US in our catalogue with different retailer listings. Neither replaces prescription-strength azelaic acid if that is what you have been prescribed.
