Broke me out so badly!

I started using the serum and I noticed weird red hard pimples started to appear on my chin! I dont usually break out or get pimples, I went to dior to know more and see if someone ever faced the same issue, the lady told me to keep using it (after I stopped for a week and saw no pimples) I stated using it again this week and BOOM pimples in the same place… honestly wont recommend and dont take the risk. I love dior so much, i am using the forever foundation/lipsticks/dior capture dream skin/perfumes and all…. But this really didnt work out.
