Dont use alcohol. Buy a soap for your face, whenever you take your shower, take the soap and rub it against your cheeks, then with your hands, spread it around. That's all. Simple task.
Go to a dermatologist, seriously. Have regular appointments with your dermatologist for as long as you live. And for the love of God, be clean, shower, and wash your face regularlt.. Pimples are highly disgusting. The throught of people popping it by themselves makes me want to throw up.
