Beta-Glucan
The polysaccharide hero of K-beauty barrier-and-soothe — derived from oat, yeast, or mushroom cell walls. Iunik Beta Glucan Power Moisture Serum and Krave Beauty's barrier-line carry it into clean prominence. Often described as 'better than HA' for wound healing in some clinical contexts; the immune-modulating angle (TLR signaling at low doses) makes it a barrier and post-procedure favorite. Searches up 181% year-on-year.

- exceptional humectant and barrier-supporting film former

Example uses

Formulation notes
Effective at 0.1–2% in serums; oat- and yeast-derived are the cosmetic standards. Pairs with HA, ceramides, and centella.
Watchouts
Source matters — oat-, yeast-, and fungus-derived beta-glucans behave differently in formula. Yeast-derived may flag for the malassezia-aware (rare).
