Common Name(s): Beta-1,3/1,6-glucan,yeast beta-glucan,oat beta-glucan
CAS Number: 9041-22-9
DESCRIPTION
What It Does: Reduces inflammation, deeply hydrates, stimulates collagen synthesis, accelerates wound healing.
Why It's Used: Used in anti-aging, sensitive skin, post-procedure, and eczema care for multi-action anti-inflammatory, moisturizing, and regenerative benefits.
How It Works: Binds to dectin-1 and cr3 receptors on macrophages and keratinocytes activating tgf-beta and collagen synthesis pathways. also activates macrophage phagocytosis for wound healing. humectant from polysaccharide hydroxyl groups.
Typically Found In: Anti-aging serums,sensitive skin products,post-procedure care,eczema treatments

SCIENTIFIC NOTE
Yeast beta-1,3/1,6-glucan receptor binding to dectin-1 on keratinocytes activates tgf-beta1, the key pro-collagen cytokine, stimulating fibroblast collagen production. this makes beta-glucan one of the few non-retinoid, non-peptide ingredients with direct receptor-mediated collagen stimulation.
