I used to have terrible acne.
Just try and keep your face clean by wiping it occasionaly through the day with a dry towel or something (I found that by washing my face with water during the day only made things worse.)
I also blow dry my face after ive had a shower...may sound stupid but it really helps. After ive got my face nice and dry I rub in a small bit of toothpaste...it really stops the pimples spreading and has a concealer type effect
Yeah thats how i got pimple free. None of those bullshit acne products work. This does. Well it did for me anyway.
and for the love of god DONT TOUCH YOUR FACE!
