Pro-xylane, also known as C-beta-D-xylopyranoside-2-hydroxypropane, Hydroxypropyl Tetrahydropyrantriol, C-Xyloside, is essentially a xylose structure, consisting of two groups of diastereoisomers, with a molecular weight of about 200.
Intuitively, the quality of Pro-xylane raw materials can be judged from the color and taste. The lighter the color and the lighter the sour taste, the better the quality.
The Pro-xylane powder supplied by our company has stable quality and has been exported for many years.
As a popular ingredient in famous brands for its excellent anti-aging effects. Mainly added to masks, face creams, serums, and eye creams in different concentrations.
Formula suggestion:
Pro-xylane+sodium hyaluronate
Pro-xylane+bilberry extract
Its two main functions are to maintain skin elasticity and prevent skin aging. You can find it in the ingredient list of many cosmetics with anti-aging effects.
Its efficacy can be ranked alongside that of retinol and peptides, but Hydroxypropyl Tetrahydropyrantriol is milder.
