Nevada-based Skinvisible has announced that its Invisicare polymer
delivery system has been included in the newly launched topical
pain relief product Stopgain.

The product has been developed by the DRJ Group, one of the leading providers of pain relief products in the US - a market that is currently valued at $250m. Stopgain is an over-the-counter pain relief brand that has now been extended with the launch of the new cream formulation, incorporating the delivery system. According to Skinvisible, the addition of its delivery system means that the product now offers pain relief for extended periods of time for individuals suffering from muscle stiffness, arthritis, or muscle strains. Indeed, the company claims that the incorporation of its delivery system has helped to provide four hours of pain relief for users, a feat that has been achieved thanks to the added efficiencies it provides for the delivery and sustained release of the analgesic. "By including Invisicare, we are offering our customers a product that is different from anything else currently on the market. We expect this advantage to be well received by both the trade and the customer,"​ said Robert Miller, CEO of DRJ. The licensing agreement will mean that Invisicare will attain a nationwide exposure as the product is expected to be distributed in around 25,000 pharmacies in the course of the next few months. The two companies also said that they were considering further opportunities to combine resources by including the delivery system in future product launches for the pain relief category. The company received a patenting license for the Invisicare technology at the beginning of 2006, which concentrated on protection of the polymer composition for the technology's delivery system. The patent has enabled the company to protect the mechanisms used by the formulation that enable the skin to cling on to skin care formulations for long periods of time. This means that the formulation benefits from longer duration of action, reduced irritation and lower dosage of active agent required. ​ These functions aim at creating better skin care products as well as enabling producers to save money on lower doses of more expensive active ingredients. Skinvisible has focused its business on providing proprietary formulations for a wide range of pharmaceutical and cosmeceutical products, as well as providing a number of solutions for providers of a range of skin care products.
