Updated September 4, 2026
Beta glucan-rich serum hydrates deeply and soothes skin; sticky texture noted.
What the community says
A concentrated beta glucan serum praised for intense hydration and soothing properties, especially on dehydrated or irritated skin. Excellent for those avoiding hyaluronic acid or dealing with retinoid irritation. Some find it sticky and it may worsen redness on sensitive or rosacea-prone skin.
