NU SKIN’S APPROACHTO ANTI-AGINGSCIENCE

TARGETING THE SOURCES OF AGING

2008: Focused on arNOX suppression

A HISTORY OF INNOVATION

ARNOX SUPPRESSION

Free radicals are unstable molecules that can cause skin aging. We’re exposed to them through pollution, UV radiation, stress, and many other factors. We also produce them naturally inside our bodies.

Many of the free radicals inside our bodies are produced through an enzyme called Age-Related NADH Oxidase (arNOX).

In 2008, Nu Skin began developing formulations to suppress arNOX and its production of free radicals.

OUR UNIQUE UNDERSTANDING OF GENE EXPRESSION

DNA Microarray Gene MapOver 20,000 Genes

Heatmap

1. The breakthrough mapping of the Human Genome allows scientists to look at an entire set of genes within the DNA.

2. Nu Skin’s proprietary understanding allows us to focus on specific sets of genes to interpret and understand their expression.

PCR Amplification GraphPCR Plate PCR Data

WE MONITOR GENE EXPRESSION OVER TIMEThe PCR plate allows scientists to monitor how genes react over time, giving a clearer and better understanding of gene expression overall.

AGELOC ME™ CLINICAL TESTING

Safety is key. Our Clinical Lab performed more than 200 sting and irritation safety tests in 2014.Efficacy is proven. We conducted 50+ in-house exploratory or confirmatory in-house clinical studies in 2014, lasting from one day to 16 weeks in duration.Results are validated. In 2014, we conducted more than 200 studies or tests at third-party research facilities.

AGELOC ME™ FORMULATIONS

In 2014, we:made over 700 laboratory batches worked on 170 different formulascreated up to 50 different iterations per formulasent 279 batches/formulas through Microbiological Challenge Test Protocol tested over 11,000 micro plates •tested over 370 batches for stability
