What is Colloidal Oatmeal?

Colloidal oatmeal comes from the oat plant (Avena sativa), where kernels are finely milled into a powder that disperses evenly in liquids without settling. This form makes it suitable for incorporation into creams, lotions, cleansers, and bath products within skincare formulations. It works by creating a thin protective layer on the skin's surface to shield against irritants, while also absorbing excess moisture or oils to balance feel. Its gentle abrasive particles offer mild exfoliation, smoothing texture without harshness, and it contributes to product bulk for better spreadability. Additionally, it imparts a softening effect through natural emollient-like properties derived from oat lipids and polysaccharides, commonly featured in products for daily or sensitive skin care routines.
