Early Usage of Facial Creams

Hello. Myka from phils. Im very conscious with my face when im 12yrs old (im now a high sch student). I convinced my mom to buy me a panoxyl with benzoyl peroxide. I applied it on my cheeks and used it for about 3days. And then my cheeks went reddish. Im so scared when the time comes my pores on my cheeks will open wider. Im now using ponds clear solutions twice a day. My cheeks have small dark holes. I dunno but they said it will continue to grow on my face until it gets uglier. :(
I now have a pimple, with a greenish liquid in 2days. When im washing my face, i accidentally removed it. I think it affects the condition of my face. :(
