What it does
- Soothes and helps calm sensitive, stressed skin.
- Hydrates and forms a light, moisture-holding film.
- Supports the barrier and a smoother-looking surface.
How it works
Beta-glucan is a long-chain polysaccharide (commonly from oat or yeast) widely documented for soothing, film-forming hydration and barrier-supporting benefits. It holds water well and adds a soft, cushioned feel; higher-molecular-weight grades sit on the surface, while smaller ones spread more easily.
Use level
- Typical use level
- typically 0.1–1%
Commonly used at 0.1–1% (often at or below 0.5%). It is viscous, so a little goes a long way.
Formulation considerations
- Water-soluble but viscous; disperse and hydrate fully in the water phase.
- Adds slip and a cushioned feel.
- Broadly compatible and gentle.
What it pairs with & what to avoid
Pairs well with
- Hyaluronic acid, glycerin (hydration)
- Panthenol, centella, oat (soothing)
Use with care / avoid
- Adding too much — it thickens strongly
Regulatory status
Beta-glucan is listed in the EU CosIng database and is a well-established soothing/hydrating ingredient.
Common questions
What does beta-glucan do for skin?
It soothes sensitive skin, hydrates with a light film and supports the barrier.
What percentage of beta-glucan is used?
Typically 0.1–1%; it is viscous, so modest levels are effective.
Is beta-glucan good for sensitive skin?
Yes; it is a gentle, soothing, hydrating polysaccharide well suited to sensitive and stressed skin.
