Beta-Glucan Series protect against irritation and environmental stressors, while providing moisture. They lock in moisture and hydrate the skin. For skin, it acts as a humectant (holds moisture), as a collagen-booster (anti-wrinkle effect), and as an immune-booster and modulator, strengthening the skin barrier to ward off any intruders. This ingredient is also used to firm and plump fine lines and wrinkles since it uses macrophages to speed up wound healing. Beta Glucan is a multi-purpose ingredient to fight the troubles our skin face daily.
