Oat extract (derived from Avena sativa) is used in topical formulations for its anti-inflammatory, antioxidant, and skin-barrier-supporting properties, largely attributed to compounds such as avenanthramides and beta-glucan. It is commonly included to calm irritation, reduce itching, and improve skin hydration.
