What is it

What is Beta Glucan?

Beta glucan is a naturally derived polysaccharide extracted primarily from oats or yeast. It has a long history in medicine and dermatology, studied for wound-healing, immune-modulating, and barrier-strengthening properties. Beta glucan is structurally capable of penetrating deeper into the skin than many other hydrating ingredients, delivering moisture and antioxidant benefits at a level that supports true barrier function.

Benefits

What does Beta Glucan do for your skin?

Beta glucan stimulates the skin's own healing response while also scavenging free radicals. Key actions include:

  • Strengthens the skin barrier and reduces transepidermal water loss
  • Provides antioxidant protection against UV-induced and environmental free radicals
  • Soothes redness, irritation, and inflammation
  • Supports post-procedure healing and recovery
  • Penetrates more effectively than many surface humectants for deep hydration
