Beta-Glucan

aka 1,3-beta-glucan · oat beta-glucan · yeast 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.

Benefits
  • exceptional humectant and barrier-supporting film former
  • wound-healing and immune-modulating
  • soothes redness and post-procedure inflammation
Example uses
  • Iunik Beta Glucan Power Moisture Serum
  • barrier-repair masks
  • post-procedure recovery
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).
