We’re here to share what we know — but don’t take it as medical advice. Talk to your medical provider if you have questions.

There’s a reason oats are a breakfast table mainstay. They’re healthy, hearty, and jam-packed with nutrients. But what about oat straw extract? 

Oat straw (Avena sativa) is a green oat grass that comes from the tops of oat plants before mature oat grains form. Its seeds are rich in iron, manganese, magnesium, and zinc, which is why it’s becoming a popular ingredient in skincare products and dietary supplements. 

While there’s still not much medical research to support the possible skincare benefits of common oat straw extract, they’re similar to colloidal oats, which have been proven to help the skin in various ways. (We bet you’ve heard of oatmeal baths for soothing irritated or itchy skin, even if you’ve never taken one yourself!)

Here we’ll share what we know so far about oat straw extract’s benefits, according to the experts.

Potential oat straw benefits for skin

In theory, oat straw extract may promote skin health as it may have the soothing properties commonly associated with oats. It’s easy to use because it can be added to products like face and scalp masks, soaps, and many others. A few of the potential benefits include the following: 

  • It’s soothing: Oat straw extract may be a calming agent, making it an excellent choice for sensitive skin types that are prone to frequent redness, dryness, and irritation.

  • It relieves itchiness: It may help to relieve skin irritation and itchiness, just like colloidal oatmeal.

  • It’s healing: Oats may accelerate the healing of wounds.¹

  • It’s anti-inflammatory: Oat straw extract may reduce inflammation in the skin, although more research is still needed.

Colloidal oats for sensitive skin

Colloidal oats may come from a similar source as oat straw extract—but with more research to back them up. They were officially categorized as a skin protectant by the Food and Drug Administration in 2003²—and for a good reason. Not only are they an emollient, a substance that softens and soothes the skin, colloidal oatmeal’s many vitamins, and nutrients are highly beneficial to the skin.

That’s why colloidal oatmeal is in many skincare products, from facial cleansers and moisturizers to body wash and bath soaks. Oat straw extract’s sister, this ingredient has been used for many years to soothe and relieve the symptoms associated with sensitive skin, such as dryness, itchiness,³ and redness. Among its benefits: 

  • It's moisturizing: Colloidal oatmeal helps lock in moisture. 

  • It relieves itching: Its soothing properties make it a good choice for itch relief. 

  • It's anti-inflammatory:⁴ Colloidal oatmeal is known to help soothe inflammation. 

  • It’s an antioxidant: Colloidal oatmeal’s antioxidant properties help fight free radicals, which can damage the body due to oxidative stress.

Oat straw side effects 

Oat straw extract has not been linked to any major risk factors, but it’s important to remember that limited research on its safety has been conducted. Researchers have not studied how it may affect children and people who are pregnant or nursing. Oat straw extract may cause skin irritation, a rash, or an allergic reaction, and our dermatology providers recommend introducing it to your skincare routine slowly. 

Oat skincare product recommendations

  • Summer Fridays Dream Oasis Deep Hydration Serum is a gentle, lightweight, quick-absorbing jelly serum that provides hydration with glycerin, hyaluronic acid, and squalane, while also soothing skin with colloidal oatmeal, chamomile, and aloe.

Does oat straw increase testosterone?

Are you wondering about oat straw extract’s impact on men’s health? Some sources claim that oat straw extract reverses low testosterone levels, but this has not been proven when it comes to oat straw testosterone concerns.

What is oat seed extract used for?

Oat seed extract is another term for oat straw extract. It potentially soothes and heals the skin, as well as potentially boosts mental and physical performance, reduces blood sugar and cholesterol, improves blood flow, enhances mental health, and reduces inflammation.

How do you take oat straw extract?

In addition to applying skincare products like lotions and creams that contain oat straw extract, you can also take it as an oral supplement in powder, tincture, or capsule form.
