Hi I'm Shoni Morris and I'm here on behalf of Expert Village. Different types of acne occurs due to clog pores and dirt build up. To understand how to treat acne you have to understand how acne occurs. You would find most of these tips to be common general since but most people overlook these preventive techniques everyday. So step number one would be to wash your face and A.M and P.M. Change your pillowcase every 3 days. Clean your cell phone everyday with a alcohol or a alcohol wipe. Make sure you wash your hand before you wash you touch your face. Use a sunscreen that is made for the face only perferable oil free unless you have extremely dry skin.
