The Home Health Nurse suggested topical magnesium to keep the scar tissue healthy after the wound finishes healing. Has anyone here used such a thing? (Yes, I will discuss with the MD and pharmacist, but friends count also.) I am seeing various ways to make it at home for WAY less than I would pay in the store, anyone have brand suggestions or preferred recipes? Epsom salts or the way more pricey magnesium chloride?
