Each tube is enough for 20 fl oz of cream or lotion at just under 1% concentration (5 g in 600 mL cream). Use in your favorite cream or add to our Canvas Base Cream or a Sea Kelp Bioferment base. The powder will not dissolve immediately but will release components slowly into the cream/lotion.

Quercetin is a favonoid (same type of compound as in Green Tea EGCG and Rutin) and is a natural chemical present in onion.

In vitro and animal studies suggest that Quercetin inhibits tyrosine kinase and nitric oxide synthase and that it modulates the activity of the inflammatory mediator, NF-kappaB. The mechanisms of anti-viral (in some cases enhanced with vitamin C) and anti-cancer activity that have been observed, again in in vitro and in animal studies, are unknown.

Another interesting property of Quercetin is its anti-elastase activity, meaning it inhibits the activity of the endogenous enzyme responsible for the breakdown of elastin, a component crucial to skin elasticity.
