I have been suffering from a facial fungus for the past five years and every dermatologist I visited simply looked through a database and offered a cream or ointment. Nothing worked until I met Dr. Co. Her approach was different - scientific by elimination. First, she checked for possible allergies over a period of a couple days and after eliminating any possible reaction from a litany of body lotions and shampoos, she finally nailed the root cause. Sorry I just forgot the medical terminology she used from Mayo clinic. The ointment she prescribed worked like magic. The facial fungus disappeared within a couple of days and my skin recovered. thank you Dr. Co.
