Beta-glucan is a naturally derived polysaccharide found in sources such as oats, mushrooms, yeast, and certain grains. It is highly regarded in skincare for its exceptional hydrating, soothing, and skin-repairing properties. Beta-glucan helps attract and retain moisture within the skin while strengthening the skin's natural barrier, making it particularly beneficial for dry, dehydrated, and sensitive skin. It also helps calm redness and irritation while supporting the skin's natural healing process, leaving the complexion feeling softer and more resilient.
In K-Beauty, beta-glucan is commonly found in toners, essences, serums, sheet masks, and moisturisers that focus on deep hydration and barrier support. Korean skincare embraces beta-glucan for its ability to deliver long-lasting moisture while soothing stressed or compromised skin without feeling heavy. It is often paired with ingredients such as hyaluronic acid, panthenol, ceramides and centella asiatica to maximise hydration, strengthen the skin barrier, and improve overall skin comfort. With regular use, beta-glucan-infused products can help restore a healthy glow, improve skin texture and leave the skin looking plump, calm, and well-hydrated.
