Is azelaic acid worth it? We read 1,910 reviews of three popular 10% picks at Sephora and Ulta to see how often reviewers say their redness, breakouts, dark marks or texture looked better, and how often they say it pilled, dried their skin, stung or did nothing: The Ordinary Azelaic Acid Suspension 10%, Paula's Choice 10% Azelaic Acid Booster and Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum. [R-SEP-TO] [R-SEP-PC] [R-ULT-ANUA] [A1] [A2] [A3]

How we read 1,910 reviews at Sephora and Ulta

We read every review each retailer served for these products, with no fixed target, skipping those the site marks as incentivized or written by staff. At Sephora we read 1,272 The Ordinary reviews and 382 Paula's Choice reviews. Ulta's pages served 256 distinct Anua reviews of 410 shown. [R-SEP-TO] [R-SEP-PC] [R-ULT-ANUA]

Of the 1,910 we read, 220 were set aside. In July 2025, 67 of the 103 Anua reviews posted on Ulta said the product was free, so we set that whole month aside (103 reviews). On Sephora, 96 Paula's Choice reviews were posted in November 2022, eight times as many as the next-busiest month (12), 86 of them five stars and none one or two stars, so we set that month aside too. Another 21 were about another product, said it was free, had no meaningful text or were otherwise unusable. That leaves 1,690 usable reviews: 1,258 for The Ordinary, 283 for Paula's Choice and 149 for Anua. [R-SEP-TO] [R-SEP-PC] [R-ULT-ANUA]

Some cautions. Each product's reviews come from one retailer, and The Ordinary's go back to 2017 while all Anua reviews are from mid-2025 on. One- and two-star reviews made up 17% for The Ordinary, 16% for Paula's Choice and 9% for Anua. Results depend on your skin and how long you use a product, and these are what reviewers say they saw, not a medical test. [R-SEP-TO] [R-SEP-PC] [R-ULT-ANUA]
