The 6 S Quality Process and the Science is what Sets Us Appart
One of the key differentiators that sets Pharmanex apart from the competition is Nu Skin’s 6S Quality Process. First created in 1996, the 6S Quality Process embodies the set of standards that Nu Skin applies to our development and manufacturing processes to ensure our products are of the highest quality. Below, we will briefly go through the first three of the six S’s that comprise the 6S Quality Process and give an example of each one in action.
First is SELECTION. Ingredients must pass specific criteria for effectiveness, suitability for formulation, and consumer safety before they are selected for use in a product. Nu Skin works with experts and raw material suppliers around the world to gather both historical and new scientific insights about the unique ingredients within our products.
Once a raw material selection is made, our scientists investigate potential commercial sources that can guarantee availability, quality, and concentration of key ingredient components. Nu Skin evaluates these raw material sources to ensure quality and suitability for product formulation, and monitors active ingredient concentration when applicable.
We believe are the safest compounds and highest quality ingredients to incorporate into our formulations. Nu Skin sets specifications to provide a basis for active compounds, ingredients, and criteria for finished products. These criteria help establish ingredient standards, and provide specific characteristics to guide consistent manufacturing. Where appropriate, Nu Skin products are carefully analyzed to not only identify the active components, but to ensure consistent manufacturing and product quality.
Raw materials must meet our specifications to certify their readiness for product manufacturing. When there are wide variations in active components of a natural or botanical ingredient, we select only those materials that provide the specified amount of these active constituents. Furthermore, our scientists strive to formulate products to contain ingredients at the concentration or strength shown to be efficacious. Once manufactured, Nu Skin products are tested to meet their finished good specifications before they leave the manufacturer.
We adhere to high product safety standards by reviewing scientific literature and conducting standard safety studies. Nu Skin conducts standard tests specific to nutrition and personal care products respectively. Examples of safety testing include testing for the presence of microbes, heavy metals, and other contaminants and determination of irritation and/or allergic reactions. Often, we confirm safety and validate our conclusions by using external testing groups.
We take great care to ensure that our products and ingredients are not only safe, but effective. Each product claim is supported by scientific literature and/or research studies. For key products, we conduct documented clinical studies to determine product and ingredient efficacy and support product and ingredient claims.
