Nu Skin’s anti-aging science is based on exclusive access to more than 30 years of anti-aging gene expression research. Nu Skin scientists have discovered not only how to target the genetic sources of ageing, but how to target multiple genes instead of single genes, to provide the best results.
Our science has the unique ability to identify and target gene expression patterns—functional groups of genes that influence specific aspects of ageing. Our discoveries have yielded worldwide media attention with numerous patents, posters, presentations, and published articles.

Mark Bartlett, Ph.D.
Vice President of Global Research and Development for Pharmanex
Mark Bartlett, Ph.D., oversees research and development for all Pharmanex® products. Dr. Bartlett’s research experience includes work in the area of cardiovascular disease with an emphasis on the role of free radicals and antioxidants, transplant research, and human autoimmune inflammatory diseases. He has published more than a dozen papers on this work in various scientific journals. Dr. Bartlett’s research led him to the United States’ National Institutes of Health where, as a visiting scientist at the world-renowned National Cancer Institute, he investigated the interaction of T cells with the blood vessel wall. Dr. Bartlett’s interest in the role of nutrition in human health and disease led him to join Nu Skin Enterprises in 1996 as a technical specialist and scientific advisor. He has since formulated many supplements and sports food products for the United States, Japan, Taiwan, Korea, Hong Kong, and Australia. Dr. Bartlett holds degrees in biochemistry and organic chemistry from the Australian National University and a Ph.D. in Immunology and Cell Biology from the John Curtin School of Medical Research in Canberra, Australia.
We have developed our own standards for our development and manufacturing processes—we maintain quality, efficacy, and safety controls through each and every stage to ensure unsurpassed results that meet only the highest standards and comply with all relevant government requirements. The key to this consistent quality in our products is what we call our 6S Quality Process. This process involves a set of rigorous, highly integrated activities and includes multiple layers of scientific testing and attention to detail. It requires consistent collaboration and a unified commitment to quality.
SELECTION
In order to be considered for use in Nu Skin products, materials must pass criteria for effectiveness, suitability for formulation, and consumer safety. 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.
SOURCING
Once a raw material selection is made, Nu Skin 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.
SPECIFICATION
Nu Skin selects what 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.
STANDARDIZATION
Nu Skin 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.
SAFETY
Nu Skin adheres 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.
SUBSTANTIATION
Nu Skin takes 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.
Throughout our company history, we believe our focus on scientific innovation has made Nu Skin a leader in the nutritional and personal care industries. Our 6S Quality Process helps us address the many variables that can affect the safety and efficacy of personal care and nutritional products. With this insight, we can continue to expand our proprietary anti-aging science into the future as we develop innovative products to help people live younger longer.
Do you test on animals?
With regards to animal testing, we only test on animals when the law requires it. We follow the rules within EMEA (Europe/Middle East/Africa) and since there is no required animal testing in these regions, it means that our products are not tested on animals.
Our ingredients are tested in-vitro. If animal testing is conducted, only the final product would be tested, not specific or individual ingredients.
Just like all normal drugs you might take from time to time (headache pills etc.) are required to have an animal testing phase before they are tested on humans, the same rule applies for supplements (only supplements, not skin care products) in some countries. Therefore, it is necessary for Nu Skin by law to perform animal studies on certain supplements in a few countries. While the laws and mandates may begin to change, at present they do require some animal testing (mandatory). This is not conducted by Nu Skin, but rather the government conducts the required tests. The government/testing agency will request a specified amount of product needed to conduct the testing necessary. We, Nu Skin, do not select nor run the test or even set up the testing with the laboratory; all of it is handled by the government. Unfortunately, we cannot provide you with more information in this regard.
Animal research plays a crucial role in scientists' understanding of diseases and in the development of effective medical treatments, and despite supplements being ‘natural’ they are still ingested and can still cause large effects/side effects. According to the Food and Drug Administration, it is not possible at this time to entirely abandon animal testing and still assure human health and safety.
With that being said, Nu Skin is committed to the development of non-animal testing. The company has contributed to the Centre for Alternatives to Animal testing at John Hopkins University and will continue to support the development of alternatives to animal testing. We hope that this research with time will eliminate animal trials completely.
