In plain English

Hydrolyzed oats are made by breaking down whole oat grains into smaller, water-soluble pieces. This process makes the oats easier for your skin to use. In skincare, they act like a gentle sponge, helping your skin hold onto moisture while also calming redness and irritation. Think of them as a comforting, hydrating blanket for your skin—perfect for when your face feels dry, itchy, or sensitive.

What it is

Hydrolyzed oats are a natural ingredient produced by treating oat grains with water and enzymes to break down proteins and starches into smaller molecules. This creates a water-soluble powder or liquid that can be easily incorporated into skincare formulas.

How it works

Hydrolyzed oats work in two main ways. First, they contain beta-glucans, which form a thin, invisible film on your skin's surface. This film helps lock in moisture and protects your skin from environmental irritants. Second, they have natural compounds called avenanthramides, which are known to reduce inflammation and calm redness. Together, these actions help soothe sensitive skin and improve hydration.

Pros

Deeply Soothing

Hydrolyzed oats contain avenanthramides, which are natural compounds that help calm redness, itching, and irritation. This makes them ideal for sensitive or reactive skin types.

Gentle Moisture Lock

The beta-glucans in hydrolyzed oats form a light, breathable film on the skin that helps prevent water loss without feeling heavy or greasy. This provides lasting hydration for dry skin.

Cons and cautions

Potential Allergen

While rare, some people may have an allergic reaction to oats. If you have a known oat allergy or celiac disease, check with your doctor before using products with hydrolyzed oats.

Texture Concerns

In high concentrations, hydrolyzed oats can leave a slightly sticky or tacky feel on the skin. This is usually not noticeable in well-formulated products but can be an issue in some serums or gels.

Best for

People with sensitive, dry, or easily irritated skin
Those looking for a gentle, natural moisturizer

Use caution if

Individuals with a known allergy or sensitivity to oats

Usage tips

Apply products with hydrolyzed oats to damp skin to enhance absorption and hydration.

Use as part of a simple routine if you have sensitive skin—pair with a gentle cleanser and a basic moisturizer.

Safety summary

Hydrolyzed oats are considered very safe for topical use. The main concern is a rare allergic reaction in individuals sensitive to oats. Patch testing is recommended for those with known food allergies.

Research notes

Research supports the soothing and moisturizing benefits of oat-derived ingredients. Studies show that oat beta-glucans can improve skin hydration and reduce transepidermal water loss. Avenanthramides have demonstrated anti-inflammatory effects in laboratory and clinical studies.

Common label clues

Typical concentration: 0.5% to 5%
Regulatory status: Generally recognized as safe for cosmetic use. In the U.S., oats are considered a food ingredient and are not specifically regulated by the FDA for cosmetics, but they are widely accepted as safe.
Common uses: Moisturizers, Soothing creams, Sensitive skin products, Baby care, Cleansers
Environmental note: Oats are a sustainable crop that requires less water than many other grains. Hydrolyzed oats are typically produced using enzymatic processes that are considered environmentally friendly.

Good to know

Hydrolyzed oats are different from colloidal oatmeal, which is finely ground whole oats. Hydrolyzed oats are broken down further for better solubility and skin penetration.
Oats are naturally gluten-free, but cross-contamination can occur during processing. If you have celiac disease, look for certified gluten-free oat ingredients.
