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+Dry Skin

    Pros

    - During summer and fall, the sun is so intense, and you can't forget sunscreen, right? But when I only apply sunscreen, using a cleanser feels like overkill... - I watched a Director Pie YouTube video that mentioned creams and cleansers basically have similar ingredients, so for light outings, I'd wipe my face with a cream and then wash it - My skin is super sensitive, so it gets red and needs a lot of calming with strong irritation - I already knew Lagom cleansers were good, but a milk cleanser? This was exactly the product I needed! - I loved the sturdy, solid container right away—it's definitely not going to leak or break - The texture isn't runny like a liquid; it's thick and creamy with fine particles and high density, that kind of feel - It applies smoothly and spreads easily, really cleaning away impurities properly - Especially! When I cleanse, I was shocked at how soft my skin feels afterward - Honestly, this is my first time using a milk cleanser, and I'm really satisfied because it removes makeup without any irritation, and my skin feels smooth during cleansing and even when I apply toner afterward - My skin is super sensitive, so double cleansing usually makes my face tingle and turn red, which is tough, but with this milk cleanser, my skin feels comfortable without any irritation—that's what I love most - If you have sensitive skin or wear light makeup, I totally recommend this!

    40s+Dry Skin

    Pros

    It's so moisturizing and free of harmful ingredients that it's perfect for using with my kids. It really helps soothe skin that's been worn down by harsh sun and heat. I'm so glad I can find gentle baby products from Roundlab too.

    40s+Dry Skin

    Pros

    The ingredients are great too. True to Atoclé toner, it feels hydrating and purifying for the skin. It's not a watery formula—it has a nice consistency to it. The hydration is excellent, so it works wonderfully for dry, atopic skin and also calms combination dehydrated skin, making it feel more comfortable. I was lucky to grab it on sale due to the expiration date discount, which made it an even better deal.

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.
