gosh, you are sure about this, i have been using that for the past few years, always apply before sleep. I don't think it darkens my skin significantly though my complexion is not fair at all. I like using 10% benzoyl peroxide cover because i can wear it on the street. Though the cream is a bit dry, it's not to the extent that you would feel the stretch of the skin. But what i am afraid is that after using 10% benzoly peroxide for too long, it will lose its effectiveness against pimples. So i have decided to use other products after i finish this tube. Not sure whether it helps, any comments from anyone?
