SALT LAKE CITY,
May 08, 2007 (BUSINESS WIRE) — USANA Health Sciences, Inc. (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."
