About Us

Our Mission

The Wound Care Co. LLC ( former Gerystone Pharmaceuticals Inc. ) is dedicated to bringing its patented platform of wound care technologies to the global marketplace, using them to improve quality of life and healthcare outcomes for patients who suffer from chronic wounds, and to lower healthcare costs associated with chronic wound treatment.


Dedicated to Making a Difference

For patients living with chronic wounds, every-day activities can be painful and challenging. The incidence of chronic wounds is a growing, global problem. In the United States alone, it is projected that the incidence of chronic wounds will rise significantly, with five to seven million chronic wounds estimated annually. The management and treatment of chronic wounds in the U.S. presently costs an estimated $20 billion per year.


At The Wound Care Co. LLC we have developed innovative new wound care technologies that can help patients with chronic and non-responding wounds lead more active, productive and pain-free lives. Our current product line includes Epi-Max® in the United States and DerMax® and MelMax® in the European Union and the Middle East. Our goal is to become a global leader in the treatment of chronic wounds and to leverage our expertise in wound treatment to develop new products and applications using our innovative Polyhydrated Ionogen (PHI) technology.

3M Relationship

After several years in development, including regulatory approval and intellectual protection, The Woundcare Company's first market ready product was a topical wound care dressing with an active drug component. This product proved extremely effective in the treatment of recalcitrant, non-healing wounds, especially diabetic ulcers. In a market starved for effective wound healing products, The Woundcare Co., captured the attention of a number of large pharma companies, including the 3M Corporation. 3M had a huge share of the traditional bandage market and was looking for the proper product to serve as an entrée into the more sophisticated, science and outcome driven advanced wound care market. After years of negotiations 3M signed a License and Supply Agreement with. By July of 09 the relationship was already beginning to show strain.
