What do the experts say about Soothing & Barrier Support Serum?
The Ordinary Soothing & Barrier Support Serum carries a Guru Score of 79% from 19 independent experts. This serum calms redness and repairs a stressed barrier with a notably lightweight texture that layers easily into both morning and evening routines. Most gurus praise the multi-ingredient approach (centella, niacinamide, gallic acid, and vitamin B12 all work to reduce visible redness and support hydration) and find it especially useful after overexfoliation, retinoid adjustment, or shaving; a few note the formula is so watery application can feel messy, and those with dry skin may want to layer it with something heavier or more occlusive to get the full barrier benefit. One reviewer found it merely okay, while another flagged that travel with the pipette bottle is fiddly.
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.
