Avena Sativa (Oat) Kernel Extract

_Avena sativa_ (oat) kernel extract is the International Nomenclature of Cosmetic Ingredients (INCI) name for a skin care ingredient you may know as colloidal oatmeal. It is primarily referred to as such on skin care product labels when included as an active ingredient in an over the counter (OTC) formula. Colloidal oatmeal is made when oat kernels are ground into a fine powder that easily disperses in a liquid emulsion. Oat kernel extract – as is the case with most plant extracts – is a good source of antioxidants that fight off the ravages of environmental stressors for a more youthful appearance. Where this ingredient truly shines though is its ability to soothe even the most stressed, irritated skin. It’s not a stretch to say that oat kernel extract is almost legendary in this regard! Studies point to oatmeal’s potent soothing properties coming from its ability to inhibit inflammatory cytokines, which are types of small proteins that help control the body’s inflammatory response. By inhibiting these cytokines, colloidal oatmeal helps the body better deal with irritation. This calming effect also helps improve skin barrier strength. The independent Cosmetic Ingredient Review panel has ruled _Avena sativa_ (oat) kernel extract safe in its current use in cosmetics – where it is included as an ingredient in nearly 500 products. When it’s an active ingredient, use levels of colloidal oatmeal range from 0.5–2%, although amounts as low as 0.007% may be used for this purpose.
