Oat SILK
Avena Sativa (Oat) Kernel Flour
Oat silk has a remarkable ability to make skin glow. It absorbs excess sebum from the skin. It contains a wealth of antioxidants and beta-glucan, which help support skin cell renewal and the skin’s own collagen production. Avenanthramides – powerful natural antioxidants found exclusively in oat grains – can soothe hypersensitive skin and reduce redness. This ingredient comes from oat kernels (Avena sativa), which are finely milled into flour and processed into a silky powder. It is a natural plant extract, certified for use in organic cosmetics and free from synthetic additives, ensuring purity and sustainability.
Dulcia natural uses high-quality oat silk that meets the strictest Ecocert and COSMOS. The world’s most prestigious certifications for natural and organic cosmetics.

Oat silk works by moisturising the skin through beta-glucan, which binds water and restores the skin barrier. Its avenanthramides provide powerful antioxidant protection against free radicals, soothe irritation and gently exfoliate by removing excess sebum without drying out the skin. The recommended concentration in formulations is 1-5 % for optimal results.
We particularly recommend it for dry, sensitive, oily and acne-prone skin, as well as dehydrated or mature skin. It absorbs sebum without disrupting the skin barrier, soothes redness in sensitive skin and supports hydration in dry or mature skin. Suitable for all skin types that need gentle cleansing and protection.
A study published in the Journal of Drugs in Dermatology (2015) showed that oat avenanthramides at a concentration of 0,03 % reduced itching by 50 % in patients with atopic dermatitis after 4 days of application. Further research in the International Journal of Cosmetic Science (2007) showed that oat beta-glucan increases skin hydration by 20 % and supports ceramide production in the skin barrier after 3 weeks of use.
