Hello I'm 18/F and I'm currently using hydroquinone 4% to try getting rid of the scar on my face.

But since two weeks ago there's a pimple growing on my face next to my scar area where I'm using hydroquinone.....

It's on the left side next to my nose, it's painful when i touch it and it's red.

The acne cream the doctor gave me called Duac once daily gel. But it has BP ....

Luckily I found out before i put it on, what should I do? Leave the pimple alone or stop using hydroquinone and put Duac on?

Because my scar is basically everywhere so I put those hydroquinone on my forehead, both sides next to my nose, right side on my cheek. They still grow acne on anywhere sometimes but this one is huge and painful.

And I think my face's skin tone is much whiter than my body, what should I do?

I'm not sure what should I do because I can't find any information about it in Chinese forum.

I don't want to have brown stains on my face...but I really want to make that pimple go away.

Please forgive my broken English and it'd be really nice if you can reply to me with simple English. I'd appreciate it a lot. Thank you!!
