Protective effects of skin barrier integrity against emotional stress, by an enriched Oat β-Glucan complex derived from Avena sativa L.

The skin stress response is the activation of the endocrine, neurologic, and immune systems triggering a cascade of impacts. Cortisol is a stress hormone and prolonged exposure to elevated levels causes an increase in reactive oxygen species. Oat β-glucans have been reported to have beneficial effects on skin health.
This work presents evidence of the protective effects of an enriched Oat β-glucan complex on the skin barrier integrity against emotional stress and on the effectiveness of delaying the first signs of skin-ageing. Clinical studies show that this complex protects against stress-related skin damage. Due to its high anti-oxidation and stress-response upregulation in genes, stratum corneum integrity is maintained, stress-induced skin thinning is reduced, and skin smoothness is improved.
