Bose by chemical name of hydroxypropyl tetrahydropyrantriol, is a kind of xylose derivatives, the appearance of sticky light yellow paste. As a cosmetic raw material, Bose is mainly composed of water, hydroxypropyl tetrahydropyrantriol and propylene glycol.

Bose has a good anti-aging effect. In addition, Bose also has the effects of promoting the synthesis of glycosaminoglycans and improving the ultrastructure of the dermal epidermal junction. With its good performance, Bose has been widely concerned by many cosmetics companies.

Bose was first discovered and extracted from beech trees by L'Oreal and is its patented raw material. Dr. Maria Dalko-Siba, the inventor and scientist of Bose Factor, said: "Between 1999 and 2000, we synthesized a total of more than 200 xylose derivatives, which were evaluated from multiple perspectives such as reliability, efficacy, stability and skin absorption rate, so we selected the anti-aging molecular Bose Factor."

Xiao Bian consulted 12 scientific literatures related to Bose cause and found that research shows that Bose cause can exert biological effects in all layers of skin (epidermis, true epidermal connection and dermis) and has been verified by human tests: Bose cause can promote epidermal renewal, strengthen skin structure, restore skin firmness and elasticity, improve wrinkles and fine lines, and increase skin luster and elasticity by promoting the synthesis of glycosaminoglycans and proteoglycans.

Bose by the choice of smell and color
Pure Bose is white powder, and the Bose we see on the market are all processed Bose solutions.
Because boson is a derivative of xylose, it is very easy to absorb moisture, and will absorb moisture into a yellow to caramel-colored viscous liquid similar to syrup in a few seconds after contacting with air. Therefore, we generally recommend to prepare 10%, 30% and 50% alcohol aqueous solutions for convenient use.

The efficacy and role of boson
1. Anti-aging. It can promote the regeneration of collagen, has the effect of delaying aging, making the skin young and shiny.
2. Increased skin elasticity. It promotes the transformation and construction of protein sugar content in proteoglycan, and has the effect of absorbing water, so as to improve the firmness of skin.
3, moisturizing. Affect the secretion of GAN, has a good moisturizing effect.
