It may feel tight after washing, sting with products, flake, or look irritated. The phrase is useful for routine troubleshooting, but it should not replace diagnosis when symptoms are painful, spreading, infected-looking, or persistent."]},{"heading":"Causes","paragraphs":["Barrier discomfort can follow harsh cleansers, scrubbing, frequent exfoliation, retinoid or acne-treatment escalation, cold or dry air, friction, fragrance sensitivity, or using too many products at once. Dry-skin references describe moisture loss and surface cracking, while moisturizer references support humectants, emollients, and occlusives in reducing water loss and improving surface comfort."]}],"ranked_product":{"title":"CeraVe PM Facial Moisturizing Lotion","url":"https://skinknowledgebase.com/products/cerave-pm-facial-moisturizing-lotion"}}
