Oat extract (derived from Avena sativa) is a botanical ingredient rich in beta-glucans, avenanthramides, and polysaccharides, valued for its soothing, anti-inflammatory, and skin-barrier-supporting properties. It is commonly used to calm irritation, reduce itching, and improve hydration in sensitive or compromised skin.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Rare | Sensitization to oat proteins can occur, more notably in individuals with atopic dermatitis or compromised skin barriers. |
| Mild transient redness or stinging | Uncommon | Occasional localized irritation upon application, usually self-limiting. |
| Contact urticaria | Very rare | Immediate-type hypersensitivity reactions to oat have been documented, particularly in sensitized atopic patients. |
