Moisturizer Answers

i have sensitive skin, a teen in less than 2 years, i just came out of the shower washing my face with just plain water & a face sponge, after that, i applied clean & clear dual action moisturizer.
i can feel it “burning” my skin.. its cooling down though. is it suppose to do that & is it suppose to show your acne more or what?
btw it says before applying put on a non-medicated cleanser, whats that mean? can i just use my st ives apricot scrub or water before applying it?
