Also known as Avena sativa, colloidal oatmeal is produced by finely grinding oats. It is a potent yet gentle humectant (that attracts and retains water in the skin) thanks to its high concentration of beta-glucan and starches, whilst also being rich in the antioxidants, amino acids and fatty acids. Colloidal oatmeal is known for its softening, soothing and nourishing abilities.
