What do the experts say about 10% Azelaic Acid Booster?
Paula's Choice 10% Azelaic Acid Booster carries a Guru Score of 74% from 19 independent experts. The formula layers beautifully and doesn't pill for most people, earning praise for its elegant texture compared to grittier azelaic acid options. Gurus consistently highlight its range: it tackles redness, acne, post-inflammatory hyperpigmentation, and even rosacea, and remains safe in pregnancy when azelaic acid alone is the concern (though the added salicylic acid introduces caution). The one genuine caveat is that azelaic acid can pill and feel less cosmetically refined, so applying it at night rather than morning works best; a few people also found the salicylic acid eventually felt like too much exfoliation alongside other actives like tretinoin, so those already using strong retinoids may want to ease in slowly or use it just once or twice a week.

Apply it right after cleansing and drying, then follow with moisturizer; if you have easily irritated skin, go easy when combining it with other actives like retinol.
