Benzac AC 5%?

I bought this today because my GP had recommended it for my acne/pimples. However he did not tell me how  much i was suppose to use... So i am just going to layer it on my affected areas, because i want this gone now. I am sick of how weird my skin is. This is going and i ain't letting it stay.

Although I know the consequences of doing this, I don't think i will have any regrets. As I have seen people do this on youtube, and this is the only way their skin cleared up for them.
Wish me luck :)
