Poor outcome of recommended product

I went to clicks to look for a product that will help with removing dark marks on my face. The lady who helped me suggested Bioderma ***mentbio daily care SPF50 as I told her I have very sensitive skin. She was adamant this would work as I told her some of my friends had suggested celltone but she said that would take longer. To my surprise after two days of using the recommended product I developed a rash around my eyes and my face felt like it was on fire. I had to stop this product that cost me over 300rands and decided to see a Dr. I was truly disappointed and even Bioderma isn't responding to my emails
