酵母精華/Yeast Glucan 酵母精華是由酵母發酵過程中提取的天然多糖體（又稱葡聚多醣）。葡聚多醣常源自於酵母，菇蕈類等細胞壁中，但以酵母中含量最高。葡聚多醣能透過刺激巨噬細胞，促進人體對病毒，細菌，霉菌的防禦能力，從而增強人體免疫力。 用於護膚品時，葡聚多醣能增強皮膚抵禦能力，減輕皮膚脫皮、紅腫、痕癢等刺激反應，並促進皮膚新陳代謝，修復受損組織。葡聚多醣亦有很好的抗氧化能力，防止肌膚老化，減淡皺紋及色斑，保持肌膚嫩滑。 The Yeast Glucan is a polysaccharide sugar, extracted during yeast’s fermentation process. Also known as β-glucan, it is usually found in the cell walls of yeast, mushrooms, etc. β-glucan boosts human immune system through the stimulating activity of macrophages,
