Irritated skin

I got the Riversol 15 day sample kit. I started using it according to the recommendations. Starting from the cleanser and then moved to the moisturizer and this is when my face became itchy and red.
I tried the serum and had same results. I was disappointed because the product is supposed to be formulated for sensitive skin, I previously read awesome reviews about the sample kit for dry skin, but it didn't work for me.
