Beta Glucan

Beta Glucan is a naturally derived polysaccharide from oats that visibly calms, hydrates and repairs the skin barrier. Known for its ability to reduce the over stimulation of inflammatory pathways and fortify the skins immune system.

This gentle yet high-performing active is ideal for skins experiencing dryness, sensitivity, stress or environmental exposure. Beta Glucan supports key barrier components by helping reduce moisture loss, enhancing suppleness and delivering a comforting protective film that does not feel heavy or occlusive.

As a functional ingredient, it works synergistically within O’s delivery systems to support active penetration while ensuring the skin remains calm, hydrated and balanced.

  • Calms the look of redness and visible irritation
  • Helps defend against environmental stressors with antioxidant-like activity
  • Softens rough texture for smoother-feeling skin
  • Helps enhance resilience for sensitive, compromised and stressed skins
  • Supports a healthier skin barrier

Form, Stability & Delivery

Beta Glucan is a stable, water-soluble polysaccharide that’s flexible molecular structure allows it to sit beautifully within O COSMEDICS’ biomimetic liquid crystal delivery systems, enhancing comfort and reducing irritation. Because it harmonises with the skin’s natural hydration pathways, it supports optimal function while reinforcing barrier health.

How Beta Glucan Works - Made Simple

1. Barrier Reinforcement & Protection
Beta Glucan forms a breathable, supportive film on the skin that helps strengthen the barrier and reduce water loss.

2. Deep Hydration Support
Its water-binding structure attracts and stores moisture within the skin’s upper layers.

3. Calming & Redness Reduction
Beta Glucan helps soothe visible redness and signs of irritation by reducing the over stimulation of inflammatory pathways.

4. Texture Softening & Comforting Action
By increasing hydration and supporting barrier repair, Beta Glucan helps improve texture and softness.

5. Environmental Defence
Its antioxidant-like qualities help defend the skin from environmental stressors that contribute to visible aging and dullness.
