玻色因，歐娘娘的專利啊
羥丙基四氫吡喃三醇：也就是Proxylane(玻色因)這是一種最早在 Lancome中使用的成分，據稱能刺激真皮層的粘多糖甚至膠原蛋白的生成，有利於幫助加固表皮層與真皮層連接。
Pro-Xylane(玻色因)屬於一種木糖衍生物，有時被稱為c-木糖苷(c-xylopyranoside，或者c-xyloside)。在歐萊雅發表的學術論文中，玻色因顯示出能夠“刺激硫酸化糖胺聚糖(GAGs)的合成 ”，GAGs包括透明質酸、硫酸皮膚素、肝素等一大類細胞外基質中的酸性黏多糖成分。此外，Pro-Xylane還能夠“增加體外培養的人真皮成纖維細胞中糖胺聚糖合成，從而有助保持細胞外基質完整性，並改善皮膚的緊致度”。人體安慰劑對照試驗中，10%濃度玻色因可起到改善真表皮連接緊密度和改善皮膚老化的作用。

Hydroxypropyl tetrahydropyrantriol anti-aging ingredient CAS No.439685-79-7
Description:
Hydroxypropyl tetrahydropyrantriol was originally an ingredient developed by Lancome in 2006. According to research, this is a glycoprotein mixture made from xylose. Beech is rich in xylose. It is well known that it can stimulate the production of glycoaminoglycans (GAGs) and prevent water loss in the skin. Hydroxypropyl tetrahydropyrantriol enters the skin and promotes the production and construction of proteoglycans in the extracellular matrix (such as gelatinous protein networks and sugars that act as scaffolds and intercellular shock absorbers).
These molecules absorb water, make the matrix gelatinous, and increase the firmness of cells and skin. It can also serve as a channel to guide repair molecules (such as proteins that grow cells). As the skin ages, the extracellular matrix gradually loses its elasticity; the cells begin to deteriorate and can no longer produce proteins that promote youthfulness, such as collagen. Hydroxypropyl tetrahydropyrantriol uses the activity of the extracellular matrix to inform aging cells what to do, send messages to young cells, and re-stimulate aging cells.
羥丙基四氫吡三醇最初是蘭蔻於2006年開發的一種成分。據研究，這是一種由木糖製成的糖蛋白混合物。山毛櫸富含木糖。眾所周知，它可以刺激糖胺聚糖 (GAG) 的產生並防止皮膚水分流失。羥丙基四氫吡三醇進入皮膚並促進細胞外基質中蛋白聚糖的產生和構建(如凝膠狀蛋白質網絡和充當支架和細胞間減震器的糖類)。
這些分子吸收水分，使基質凝膠狀，並增加細胞和皮膚的緊致度。它還可以作為引導修複分子(例如生長細胞的蛋白質)的通道。隨著皮膚老化，細胞外基質逐漸失去彈性；細胞開始退化，不能再產生促進年輕的蛋白質，如膠原蛋白。羥丙基四氫吡三醇利用細胞外基質的活性來告知衰老細胞該做什麼，向年輕細胞發送信息，並重新刺激衰老細胞。
據蘭蔻實驗室(非獨立實驗室)稱，“實驗和人體實驗表明，改善是全面的，不僅限於細胞外基質：還有基質與細胞之間的聯系，皮膚的密度和緊致度. , 或促進膠原蛋白等年輕纖維的產生. 沒有研究報告表明含有羥丙基四氫吡三醇的產品有負面信息或不良副作用
