LAS VEGAS -- Skinvisible, Inc., a topical drug delivery company that out-licenses its family of polymer delivery vehicles, Invisicare, to established developers and manufacturers of prescription, as well as over-the-counter, dermatological, medical, cosmetic and skincare products, announced today that it has been issued a second patent by the U.S. Patent and Trademark Office protecting the polymer composition of the
Company's Invisicare polymer delivery system. When topically applied, Invisicare-formulated products hold active ingredients on the skin for up to four hours -- thereby affording the active ingredients an extended timeframe to perform their intended functions.
Previously, a patent was issued to Skinvisible related to the method of manufacturing Invisicare. A third patent application, related to methods of use of Invisicare is pending.
"The issuance of this second Invisicare patent protects the unique mechanism by which we can safely deliver formulated products using Invisicare to remain on the skin for extended periods of time, resulting in improved efficacy, longer duration of action, reduced irritation and lower dosage of active agent required. This patent thus represents another significant milestone for our company, one that continues to validate the novelty of our technology platform," said Terry Howlett, president and CEO of Skinvisible.
At the heart of Skinvisible's patented technology and trademarked Invisicare family of polymer delivery vehicles is its formula and process for combining hydrophilic and hydrophobic polymers into stable complexes in water emulsions. This allows formulated products using Invisicare as their platform to remain on the skin for extended periods of time, thereby affording active agents a prolonged timeframe to perform their intended functions. Products utilizing Invisicare have the proven ability to bond active ingredients to the skin for up to four or more hours. They are non-occlusive and allow normal skin respiration and perspiration while moisturizing and protecting against exposure from a wide variety of environmental irritants. When topically applied, these formulated products adhere to the skin's outer layers, forming a protective bond, resisting wash-off, and delivering targeted levels of therapeutic or cosmetic skincare agents to the skin. They allow enhanced delivery performance for a variety of skincare agents resulting in improved efficacy, longer duration of action, reduced irritation and lower dosage of active agent required. The "invisible" polymer compositions wear off as part of the natural exfoliation process of the skin's outer layer cells.
