As the skin ages its immune competence declines - production of anti-inflammatory cells is reduced and the adaptive immune response slows down. This accelerates skin ageing by allowing pro-inflammatory cells to degrade structural proteins, reducing the elasticity and firmness of skin.

Yeast beta glucans are one of the most well-known immune-modulatorsxi, able to exert anti-inflammatory effects on skin cells and enhance the formation of the skins structural proteins - increasing skin elasticity and preventing wrinkle formation.
