By rational design of pharmaceutical formulation method, utilizing strictly selected specific enzymes, 

biosynthesis means

Introducing hydrophilic groups without changing the structure of quercetin parent nucleus

Increase the solubility of functional components in water.

Significantly improve the bioavailability, which is nearly 18 times higher than traditional quercetin.

No introduction of risky substances, safer and more efficient

0.01% QUERCARE reduces active oxygen levels by 23.07% more than the same concentration of VC. 

0.5% QERCARE reduces active oxygen levels by 72.68%.

0.5% QUERCARE caninhibit 39.37% of the inflammatory response caused by UV light.

QUERCARE canprotect the integrity and densification of the stratum corneum.

And protects the thickness and densification of the granular layer and the stratum spinosum.
