Immune Defense & Superior Hydration

Overview

A polysaccharide sugar derived from the cell walls of mushrooms, oats, or yeast. Beta-Glucan is a fascinating ingredient because it holds 20% more moisture than Hyaluronic Acid, yet also functions as a powerful skin-soothing agent and immune booster. It activates macrophage cells in the epidermis, helping the skin defend against pathogens and repair tissue.
A super-hydrator that holds more water than hyaluronic acid while actively calming redness and repairing skin damage. It forms an invisible, breathable, moisture-locking veil over the skin that provides deep, long-lasting hydration. Because it is highly anti-inflammatory, it immediately soothes sunburns, eczema, and severe irritation. It also penetrates deep into the dermis to stimulate collagen synthesis, serving as a dual-action plumping and anti-aging active.
