2% hydroquinione (spelling?). Also you can go to a derm and what they will most likely do will put you on retin a or something of the like to really exfoliate plus get rid of any residual acne once and for all with a bleach cream. Just make sure you are reallyc lear cause retin a will make you breakout and I found that by doing this combo on skin with clogged pores made my skin get more marks, go figure. Chemical peels help as well plus help with acne. You can try to find someone who does glycolic peels. Also use a sunscreen when you do this stuff, the fading cream you are talking about and what I am mentioning needs to be used with sunscreen to be fully effective. Azeliac acid helps as well and is a prescription acne med too you can get from your doctor. Hope I gave you some ideas.
