Description
what is Pro xylane?
Pro Xylane, commonly known as Bose, is a xylose derivative with anti-aging activity that can promote collagen synthesis, make the skin stronger and more elastic, improve neck lines, and prevent aging. Bose is a mixture of glycoproteins derived from xylose. Due to the abundant presence of xylose in oak trees and its ability to promote the production of glycosaminoglycans, namely glycosaminoglycans (GAGs). As a substance extracted from the oak tree, Bose has a similar function to xylose.
Bose Einstein is a non-ionic surfactant with good dispersibility and emulsifying properties. Therefore, in the early stages, low concentrations of Pro Xylane were also used as emulsifiers or dispersants in skincare products with limited potential. But after all, there is a skin barrier to block it, and due to the weak biological activity of Bose, it needs to reach a high concentration on the surface of the skin in order to increase absorption through permeation through concentration gradients. However, high concentrations of hyaluronic acid have a high viscosity and are not very comfortable to use, so the proportion of hyaluronic acid added in most products is not high.

Does Pro xylane have biological activity?
Pro xylane is generated by the conversion of xylose and has a wide range of biological activities. It can activate the synthesis of mucopolysaccharides (GAGs), promote the production of hyaluronic acid and collagen; Bose Einstein can also improve the adhesion between the dermis and epidermis, promote the regeneration of damaged tissues by inducing the synthesis of structural components of the dermis and epidermis, help maintain the elasticity of the dermis, and prevent skin aging. Research has shown that Bose is easily biodegradable, does not accumulate in organisms, and is non-toxic.
What are the functions of Pro xylane?

1. Stimulate the generation and construction of GAGs (kudzu polysaccharide extracellular matrix) (such as gel shaped egg plasma network and sugar as scaffold and intercellular shock absorber) to make the matrix gel shaped, increasing the tightness of cells and skin.
2. As a guide for repairing molecular pathways, such as proteins that promote cell growth.
3. Utilize the activity of the extracellular matrix to send information to young cells while re stimulating aging cells
4. Strengthen the function of the basement membrane and reduce the occurrence of allergies and inflammation. The skin improvement effect of Pro xylane is comprehensive, not limited to the extracellular matrix, but also the connection between the matrix and cells, the density and tightness of the skin, and the promotion of self generation of type VI and Iv collagen eggs. Bosein, along with niacinamide and clotting acid, is listed as one of Teacher Cai's favorite three major skincare ingredients.
What is the Pro xylane's principle of action?
Pro xylane can increase the water content between extracellular matrix by stimulating the generation of glycosaminoglycans (GAGs). Thus fully filling the gaps of ECM, reducing wrinkles and making the skin appear more delicate. At the same time, it plays a role at the DEJ site, promoting the synthesis of collagen VII and collagen IV, making our epidermis and dermis more tightly connected, making the entire skin appear fuller, firmer, and more elastic.

What are the benefits of Pro xylane on the skin?

Pro xylane can induce the biosynthesis of GAGs, mucopolysaccharides, and PG proteoglycans in the superficial epidermal layer. The absence of GAGs and PG can lead to a decrease in skin moisture content and defense ability; Effectively promote the tight connection between epidermis and dermis, better fix the dermis layer, make the skin stronger and more elastic; Long term use effectively improves wrinkles and fine lines on the face and neck, and promotes the regeneration of damaged tissues.
1. Activation of GAG synthesis: This high-tech ingredient, based on biomimicry principles, is activated by a sugar called xylose to promote GAG synthesis. There are a large number of mucopolysaccharides in the extracellular matrix (ECM) of our skin, most of which are carbohydrate polymers (GAGs) composed of glucuronic acid and glucosamine. These mucopolysaccharides play a very important role in the skin because they can absorb moisture and prevent the loss of skin moisture. At the same time, due to the absorption of a large amount of water by polysaccharides, they can form a structure that can be imagined as a gelatinous body composed of water. At the same time, the water absorption capacity of the molecular structure of these protein glycosaminoglycans GAGs makes the matrix network structure more elastic, which helps to improve cell tightness and enhance skin elasticity. And these are important factors that affect the elasticity and texture of the skin.
2. Stimulate the production of skin amino glucans (GAGs): Hydroxypropyl tetrahydropyran triol is a glycoprotein mixture that can stimulate the production of skin amino glucans (GAGs). GAGs are the main components of extracellular matrix, and hyaluronic acid is one of the main components of GAGs. Hyaluronic acid has strong water absorption and storage capacity. When injected into the dermis layer, it can achieve the effect of filling and softening the skin, making the skin full and elastic. Hyaluronic acid is also commonly used to fill sunken areas of the skin, including wrinkles. From the perspective of skin structure, GAGS is mainly composed of collagen, elastin, and extracellular matrix (including GAGs) in the dermis layer of the skin.

How is Pro-xylane synthesized?
|
|
The initial synthesis route of Pro xylane was to use a large amount of xylose extracted from beech as the main raw material, and undergo Knoevenagel condensation reaction with acetylacetone in alkaline aqueous solution (i.e. compounds with active methylene groups (such as malonates, β - ketoesters, cyanacetates, nitroacetates, etc.) under the catalytic action of ammonia, amines or their carboxylate salts, undergo aldol condensation with aldehydes and ketones, dehydrate to obtain α, β - unsaturated compounds), and generate 1-C - (beta-D-xylopyranosyl) - acetone. Afterwards, it undergoes a reduction reaction reduce the ketone carbonyl group in the product, resulting in 1-C - (beta-D-xylopyranosyl) -2-hydroxy-propane, also known as Pro xylane. |
