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.

    40s+Dehydrated Oily Skin

    Pros

    ** Cica Barrier Bio Repair Ampoule ** I'm sharing this review after winning The Hwahae Testers selection! I've always been really interested in skincare and cosmetics, and I'm actually a certified custom cosmetics formulation manager working at a dermatology clinic, so here's my honest take! Container - It's a spray pump bottle, but instead of spraying widely, it dispenses in a narrow, targeted stream like a regular pump. I love this! Formula - The formula is watery with no viscosity, so it makes sense that it's in a narrow-spray container. It's like a milky water texture, and as you massage it in, it starts to feel tacky and bouncy. I can feel it getting thicker as the warmth builds up from rubbing it in. Scent - The fragrance is honestly subjective, but it's not particularly aromatic. It's not unpleasant either, but it feels almost unscented? Kind of in between... Hydration - I don't recommend using this alone! It doesn't actually infuse hydration into your skin. The tacky, bouncy feeling suggests it works by layering to create a moisture barrier that prevents water loss rather than adding moisture directly. Barrier improvement - After application, there's a slight feeling of being coated or sealed with a protective layer. It doesn't feel thick or heavy, and it's not an oily film—it's more like a protective covering. If this effect is maintained, it seems to really protect your skin barrier. Soothing and redness relief - Honestly, it's hard to feel immediate results in this area. There is a slight calming effect after application, but if you're expecting dramatic redness reduction, you might be disappointed. Bouncy glow feeling - Excellent! Thumbs up! Conclusion - If you're looking for an essence that gives you that bouncy, plump feeling, you'll definitely be satisfied. However, I'd recommend using a hydrating ampoule first before applying this product. I personally apply a hydrating ampoule first, then layer this product twice. Since it's been dry lately, I finish with a thin layer of La Roche-Posay Cica cream on top.

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.

Is beta glucan the same as hyaluronic acid?
