First off, what does USP mean?

The United States Pharmacopeia (USP) is a scientific nonprofit organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed and consumed worldwide.

It was founded in 1820 and merged with the National Formulary and Drug Standards Laboratory (NF) in 1975.


 And why does it matter?

USP-designated ingredients meet or exceed standards of purity set by the United States Pharmacopeia making them the highest quality grade.

Only prescription drugs are required to meet USP standards. However, all active ingredients in Vivant products (and many of the inactive ingredients as well) are USP grade.

Why do we use USP ingredients?

Because quality matters. Impurities in ingredients can render formulations less effective and less consistent. They can also cause irritation or allergic reactions.

Our goal is to create highly effective formulas while eliminating impurities and inconsistencies, reduce irritants, and provide sustainability.

Is there a difference between USP and pharmaceutical grade? 

Pharmaceutical grade products must use USP grade ingredients, but containing USP ingredients does not make a product pharmaceutical grade. Pharmaceutical grade products are available only through prescription and contain active ingredients that are classified by the FDA as drugs.


Why don’t all skin care manufacturers use USP ingredients? 

Quality is expensive. Most manufacturers opt for cheaper alternatives. Or, they may use USP ingredients in smaller percentages, which makes the product less potent.

We’re also kind of picky about our manufacturing process.

All of our products are manufactured in small batch production in the United States under clinical conditions by people earning a fair wage. We’ve been doing it this way for over forty years. And we’re not planning to change.
