Dr. Dean Hsieh

The story of SESHA SKIN THERAPY began as a biomedical endeavor over 20 years ago when Harvard and MIT educated scientist, Dr. Dean Hsieh, discovered a way to deliver large density drugs into the body through the skin as an alternative to pills or injections.

The story of Sesha began as a biomedical endeavour over 20 years ago, when the Harvard educated scientist, Dr Dean Hsieh, developed a way to deliver drugs into the body through the skin as an alternative to pills or injections.

Permeation Enhancement Technology was discovered and patented by Dr. Dean Hsieh, a pharmaceutical scientist educated at M.I.T. and Harvard.In 1984 Dr. Hsieh founded Conrex Pharmaceutical Corporation, a Drug Delivery Research and Development company.Conrex first utilized this Permeation Enhancement Technology in the medical field to deliver therapeutic ingredients through mucous membranes and the skin.

Combining Cosmeceutical and Nutraceutical ingredients and concepts, Dr. Dean Hsieh recognized that if our skin received high-grade vitamins, antioxidants and phytonutrients at its regenerative cellular level, we could recover and maintain stronger, healthier, and younger looking skin.

Conrex was founded by MIT and Harvard educated scientist, Dr. Dean Hsieh, in 1985 as a bio-applications company in an effort to develop improved drug delivery systems. After many years of research, Dr. Hsieh discovered Permeation Enhancement Technology™ (PET™), which enables penetration of large molecules through the skin's protective outer layers.

Dr. Dean Hsieh, founder Dr. Dean Hsieh is the founder of Conrex Pharmaceuticals Corp. and the developer of PET™. As a biomaterials scientist, Dr. Hsieh received his master's degree and PhD from the Massachusetts Institute of Technology (M.I.T.) and continued his post-doctoral work at Harvard University's medical school. Upon completing his education in New England, Dr. Hsieh taught at Rutgers University in New Jersey as an assistant professor. While on the faculty at Rutgers, Dr. Hsieh reached a pivotal point in his career: he edited a two-volume study, "Controlled Release Systems," which gave him an overview of the field of alternative drug delivery technology. Through his role in the study, Dr. Hsieh was able to see where the market niches were and founded Conrex in 1985.

Dr. Hsieh dedicated his research at Conrex to the study of permeation enhancement technology in hopes of finding a drug delivery method with the potential to give people access to a wider range of drugs with a higher safety factor than conventional delivery methods.

Recognized as an expert in drug delivery technology, Dr. Hsieh published over 70 scientific articles, is the editor of two books on drug delivery, and was the organizer and moderator of the drug delivery panel at the PharmTech Conference.

Due to unfortunate circumstances, Dr. Hsieh passed away in 1995, leaving Conrex under the direction of his wife, Phyllis Hsieh.

Harvard and MIT graduate, Dr. Dean Hsieh, discovered in 1991, Permeation Enhancement Technology (PET®).He founded Sesha Nutraceutical, fused his technology with powerful antioxidants and skin building nutrients.
