Beta-Glucan Essence

A minimalist essence from Mixsoon — the K-beauty brand that built its reputation on single-ingredient hero formulas — featuring just four ingredients, with beta-glucan as the star. Beta-glucan is a polysaccharide derived from oat and mushroom cell walls, and it's having a real moment in skincare for good reason: it holds onto moisture about 20% better than hyaluronic acid, calms irritation, supports the skin barrier, and (despite being a large molecule) has been shown to penetrate down to the dermis where it can actually work on fine lines.

The texture is watery and lightweight, absorbing in seconds with no tackiness. Mixsoon uses a 72-hour low-temperature extraction (under 50°C) to keep the beta-glucan's structure intact and active. That's it. Four ingredients — water, butylene glycol, beta-glucan, glycerin — no fragrance, oils, silicones, parabens, sulfates, or common allergens. The kind of essence you can layer into any routine without worrying about interactions with the rest of your products.

Best For: Sensitive, redness-prone, dry, or barrier-compromised skin — also a smart pick for anyone with a packed routine who wants a simple, no-clash hydrating step that plays well with everything else.
