Caused Chemical Burn

I bought this product from Rexall for 99 cents, so my expectations were not high. However, I did not expect to get burns. About a minute after I coated my face in the mask it began tingling, and then burning. I never buy masks so at first I contemplated if it was normal. But no, after I frantically removed the mask my skin was left with noticeable redness and soreness where the mask had been. Two days later it still stings like a sun burn. DO NOT BUY THIS!
