With acne, you have to focus on the things you can control. However, acne is primarily caused by things you cannot control, including excess skin oil, faster growth and shedding of skin cells, and genetic factors. Other potential causes include:

• Faster growth and shedding of skin cells that combine with skin oil to plug skin pores
• For women, their period—make sure you are treating acne before, during, and after your period
• Pregnancy—consult your dermatologist before using any medication if you are trying to get pregnant and while you are pregnant
• Stress—exercise is the best way to relieve stress and, since acne can cause stress, treating it may also help reduce stress
• Oil and grease from a work environment—follow your skin cleansing routine carefully
