Beta-Glucan: Benefits, Best Korean Picks & What to Know

Beta-glucan is a polysaccharide (a sugar-based molecule) found in oats, yeast and mushrooms. Beta glucan for skin is valued for a hydrating, soft and comfortable feel, and it's commonly found in toners, essences and creams for dry or sensitive-feeling skin. A beta glucan serum is the easiest way to add it, and beta glucan skincare is often paired with centella, panthenol and ceramides. On labels, look for "Beta-Glucan" or "Sodium Carboxymethyl Beta-Glucan." As with any new product, patch test first.

Benefits of Beta-Glucan

Beta-glucan is a polysaccharide found in oats, yeast and mushrooms. In skincare, beta glucan skin benefits center on hydration and a soft, comfortable feel, which is why it's a common pick for dry or sensitive-feeling skin. Its light, slightly silky feel suits watery toners, essences and serums, so a beta glucan serum fits as an early layer before moisturizer. It pairs well with centella, panthenol and ceramides. As with any new product, patch test first.

Tip

Skin still feels dry?

Apply a beta-glucan toner or essence on damp skin, then lock it in with a ceramide or hyaluronic acid moisturizer.

    Pros

    I feel like I've tried hundreds of cleansing products throughout my life. Since they're consumables and essential whenever I wear makeup or use sunscreen, I've gone through quite a few. I'd always been curious about Lagom products after seeing reviews on TV saying they're incredibly gentle and effective. Lagom Oat Micellar Cleansing Milk is a makeup remover made with oat extract. You just pump it onto your dry face with makeup or sunscreen on, massage it in with rolling motions to dissolve the makeup, then wipe it off with a tissue or do a second cleanse with a foam cleanser. It's so soft and gentle, yet the cleansing effectiveness is really impressive. If it feels too slippery, it can feel a bit heavy, but this one gives just the right finish and feels gentle, which I love. They apparently made this product using Aquarichsia, a component from African acacia trees, to help with hydration. Since they used an ingredient that maintains moisture even in arid environments, it feels more trustworthy somehow, and I can definitely see why it feels so hydrating. There are countless cleansing milk products on the market, but among them all, I really recommend Lagom Oat Micellar Cleansing Milk for its excellent hydration, gentle formula, and strong cleansing power.

Frequently Asked Questions

What does beta glucan do for sensitive skin?

Beta glucan is known for its soothing and skin-barrier-supporting properties, which makes it a popular pick for sensitive, reactive or compromised skin that needs calming without added irritation.
