Query: Rash - sensitive skin

I didn't believe I had sensitive skin. However, at the advice of a friend I purchased the Olay ant-aging 7 in 1 daily moisturizer. After about 4 days of use I had patches of dryness on my checks. It looked very ashy. I went back to my L'Oreal Age Perfect. This product should be tested before you purchased it.
