I have acne prone skin and have tried multiple brands and methods to help clear it up. it seems like everything I buy makes it worse including random drugstore brands, specialty treatments, and even facials. a friend of mine recommended Mary Kay but I'm hesitant to try any of their stuff because it’s kind of expensive and I’m not sure how my skin will respond to it. will these products cause my acne to flare up or my skin to break out? Is there a way to try products before i buy them or do i just have to guess at what my skin needs?
