Hi, I hope someone will give me a good response regarding hyroquinone. I was reading some of the beauty skin poduct with hydroquinone as one of the ingredient. What is this do? I used dermanew microdermabrasion for about a month and it look like my dark spots got worse. I don't know what did I do wong? maybe too much pressure when I used it because it got red mark and it look more obvious than used to be. I need help from other people who got an experienced using microdermabrasion. I really appreciate any response. Thank you.
