Despite the controversy that has surrounded DMSO for nearly 40 years, it seems to have a wide safety margin, especially for the topical applications most useful to plastic surgeons. Molecular weight, shape, and electrochemistry determine which drugs DMSO can effectively carry through cell membranes. However, there has been a lack of development in the potential medical applications of DMSO. It is believed that DMSO protects the integrity of cell membranes during injury,48 especially defending against attack by hydroxyl radicals, which are generated at a high level after ischemic injury.
