USANA Health Sciences Receives U.S. Patent on Exclusive Self-Preserving Technology for Skin Care and Beauty Products.

- Technology Offers Long-Sought Alternative to Artificial, Paraben Preservatives -

SALT LAKE CITY -- USANA Health Sciences, Inc. (NASDAQ:USNA) received notice of an official patent, to be released at 10:00am EST from the United States Patent & Trademark Office, for its exclusive self-preserving technology currently used in the company's Sense beautiful science[R] skin and personal care product line.

This patent covers USANA's formulation for manufacturing the Sense skin and personal care product line so that they are capable of maintaining an industry-standard, two-year shelf life without the need for added chemical preservatives. USANA's now-patented "self-preserving" technology utilizes a variety of proprietary blends of purifying botanicals, antioxidants and other active ingredients in protective liquid crystals to keep the product fresh naturally. The Sense line maintains its shelf life without the use of parabens or other chemical preservatives commonly used in other cosmetics and skin care products. Sense has utilized this self-preserving technology since September 2004 on a patent-pending basis, and it is the only skin care and beauty care product line in the world to implement this scientific advancement.

USANA scientists believe this patented process represents a significant innovation in the skin-care industry, as self-preserving technology will allow users' skin to receive all the benefits of pure, natural, and healthy ingredients without the use of chemicals or potentially harmful preservatives.

"This patent is the result of nearly 10 years of research and development by USANA scientists, and it is an important milestone in our company's drive to become a leader in the skin and beauty care industry. USANA's self-preserving technology has changed skin and beauty care in a meaningful way by allowing for the formulation of healthy, all-natural products," USANA President Dave Wentz said. "Our customers rely on USANA's high-quality products to enhance their quality of life. Just like our pharmaceutical-grade supplements, USANA's Sense skin and beauty care line offers the best - and healthiest - products available. Consumers can now enjoy healthier skin and the peace of mind that comes with safe, self-preserving technology that does not rely on artificial, chemical preservatives."
