I found out the red, stingy face way that I'm allergic to a preservative called hydroxybenzoates. I loved my Neutrogena Oil Free range the past few years but all of a sudden my face tingled whenever I use it. I don't know if it's the new formula or whether my skin has gotten sensitive over time from my Oratane acne meds. Being a bit dopey, I thought the redness in my skin was from being generally hot and sweaty after blow drying my hair. But no, it was my skin reacting to the moisturiser.
