Puri-Xylane, commonly known as Boseine, is a xylose derivative with anti-aging actives, which can promote the synthesis of collagen, make the skin stronger and more elastic, improve fine lines in the neck, prevent senescence. Boseine is a mixture of glycoproteins derived from xylose. Since xylose is abundantly present in beech trees, it has the ability to promote the production of glycosaminoglycans, namely glycosaminoglycans (GAGs). As Boseine extracted from beech trees, its effect is similar to that of xylose. Bosein is also a non-ionic surfactant with good dispersing and emulsifying properties. Therefore, the initial low concentration of Bosein was also used as an emulsifier or dispersant for skin care products. However, after all, there is a skin barrier, and the biochemical activity of Boseine itself is weak, so Boseine needs to reach a higher concentration on the skin surface before it can increase the absorption through osmosis by means of a concentration gradient. However, the high concentration of Boseine has high viscosity and is not very comfortable to use, so the proportion of Boseine added in most products is not high.
