I have been reading all your questions and you are very young, 13. A lot of people joke on here with their answers, just read them with a sensible mind ! At your age you will get pimples, it is part of growing up, the skin will become more greasy so you will have to keep it very clean with products like Simple from Boots. Go into your local branch of Boots, or a reliable chemist, and ask the lady at the counter what she thinks you should use. If you have acne, which is much worse than little pimples, you will have to go to the doctor for something that you can't buy over the counter. Good luck, and don't forget, a lot of the answers on the Answerbank are joking ... so you must decide who are answering properly and who are not !
