Hello,I have recently started using a moisturizer called Moisturex containing urea and lactic acid. It seems immidiatley after applying  this cream my skin turn quite dark. I was wondering if this is a temporary reaction to lactic acid. Would this side effect subside with long-term use.Thank you
Hello and welcome to Chat Doctor, I read your query and understood your concern. It is unlikely that any of the contents of moisture will cause skin darkening. But maybe since it is quite greasy it may give appearance of darkening. Apply a very little amount on your face. If still it doesn't help you may want to switch cream. Also since lactic acid is mild exfoliating apply sunscreen whenever you go out. Hope I helped
