Oat Kernal Flour

INCI: Avena Sativa Kernel Flour

Avena Sativa Kernel Flour is a finely milled powder obtained from grinding oat (Avena sativa) kernels, retaining the starches, proteins, lipids, beta-glucans, and antioxidant avenanthramides naturally present in oats. It functions as an emollient, absorbent, and mild physical exfoliant that forms a protective film on the skin surface to retain moisture and reduce transepidermal water loss. Its beta-glucan and avenanthramide content deliver well-documented anti-inflammatory, soothing, and antioxidant effects, making it a cornerstone ingredient in sensitive and compromised skin formulations.
