Colloidal oatmeal is finely ground whole oats suspended in water, allowing the skin-soothing compounds to be easily absorbed. Used for centuries to calm irritation and dryness, colloidal oatmeal remains one of the most gentle and effective ingredients for supporting healthy skin. It contains beta-glucans, avenanthramides, and natural antioxidants, which together help moisturize, protect, and reduce inflammation.

• Moisture-retention & hydration
The beta-glucans in oats form a lightweight protective film on the skin that holds moisture in, leaving the skin soft and hydrated after washing.
