Before the skincare industry became obsessed with buzzy active ingredients like niacinamide or retinol, one humble ingredient had already earned its place in bathroom shelves and dermatologist-approved formulas: oats.

From baby lotions to face serums and soothing bath soaks, oats have long been a staple in gentle, skin-friendly products. But what exactly makes this effective in beauty—and does the research back it up? To learn more, Manila Bulletin Lifestyle caught up with Eleanor Dorado, APAC research and development manager for Skin Health at Aveeno, to uncover the science behind this time-tested beauty ingredient.

“Oats are a natural powerhouse,” says Eleanor. “They’re rich in phytochemicals that make them especially effective in treating skin conditions caused by inflammation or a compromised skin barrier.”

At the center of oat-based skincare is colloidal oatmeal—a finely milled version of oats processed specifically for topical use. According to Eleanor, it’s not just gentle—it’s also clinically proven. “Colloidal oatmeal is the only single skin protectant over-the-counter active ingredient that can claim to temporarily protect and relieve symptoms of eczema, as recognized by both the US FDA and Health Canada,” she explains.

So what’s in oats that makes them so good for the skin?

“Oats contain a unique blend of polysaccharides like beta-glucans, proteins, lipids, saponins, vitamins, minerals, and powerful antioxidants such as avenanthramides,” says Eleanor.

Here’s how these natural compounds work their magic:

If you’ve ever wondered whether the oats in your kitchen can double as skincare, the answer is—not exactly.

“Whole or rolled oats were historically used in baths to soothe the skin, even dating back to ancient Egypt,” Eleanor shares. “But they were messy and didn’t mix well in water. Thanks to modern technology, colloidal oatmeal—created in 1945—retains all the benefits but in a form that’s easier to apply and more effective.”

This finely ground form allows oats to blend seamlessly into lotions, creams, and cleansers without clumping or creating a mess.

For those with easily irritated skin, oats may be a holy grail ingredient.

“Oats are ideal for sensitive or reactive skin types,” says Eleanor. “They soothe, rebalance, and help repair the skin barrier. Plus, avenanthramides help inhibit inflammation and oats have prebiotic properties that support a healthy skin microbiome.”

With their wide range of benefits, oats stand out even among other well-known soothing ingredients. “While aloe vera and chamomile are also known for their soothing properties, colloidal oatmeal offers a holistic set of actions that address not just symptoms but also underlying causes,” she adds.

Not all oat skincare is created equal. So how can consumers be sure that they’re getting the real deal?

“Check the label,” advises Eleanor. “Look for Avena Sativa (Oat) Kernel Flour—that’s colloidal oatmeal. Also, choose brands with clinical testing and credibility. You’ll often find this information on the packaging, official websites, or in scientific publications.”

Whether you’re managing eczema, soothing dry patches, or simply looking for a natural and gentle way to nourish your skin, oat-based products offer both tradition and science-backed results in one powerful package.

So the next time you’re browsing the skincare shelves, consider reaching for this time-tested ingredient. Your skin might thank you for a calm, healthy glow.
