L-Ascorbic Acid - Ultra Fine

L-ascorbic acid is the top-tier form of vitamin C for your skin. Its immediate availability, skin-identical nature, and unparalleled effectiveness in antiaging and anti-hyperpigmentation skincare have solidified its dominance in the skincare world for many years. 

Regrettably, L-ascorbic acid's instability in water-containing products poses a significant challenge. DIYers resort to making fresh toner and refrigerating it, a solution that lasts only a week. This presents a considerable hurdle for businesses. The most viable solution for creating sellable products seems to be the formulation of waterless products.

Ultra-fine L-ascorbic acid is perfect for making vitamin C in silicone products. Because of its micron size, it can be applied to the skin smoothly. 

The physical size: 100% of ultra-find L-ascorbic acid passes through 100 sieves, and 95% passes through 200 sieves.
