buy skin product and i have a alergic reaction

I am sorry to hear about this. It appears we never know which medications or chemicals end up causing harm to our bodies. This type of case is more fitting for a "product liability" attorney to evaluate. They deal with injury done by products which seems to fit your case. I would recommend contacting one of those. I suppose we have to take Dr. Oz's advice with a grain of salt. I hope your face heals quickly. Thank you for contacting us. Dr. Guy Regev.
