Well, hygiene is definitely a very important factor when it comes to acne. There are certain everyday hygiene steps that you should follow, like washing, but not over washing. This does not mean that you can skip the washing. Every time you come back from the outdoor you must wash your face. Be most careful about the T zone, which are forehead, nose and chin. These areas secrete oil and have the most chances of getting acne. Therefore be extra careful here. Also, it would be nice if you can cleanse your face with a good cleanser.
