Refund request for cosmetics causing skin problem

Question:

During my short trip to Korea, I purchased some cosmetics and dietary supplements at several local stores. After using them for a couple of weeks, I began to experience serious skin troubles and various health issues. I believe all the problems have been caused by the cosmetics and dietary supplements bought in Korea. I’d like to get my money back but don’t have any information about the sellers. What should I do?
