When your oil glands produce extra oil, it shows up on the top of your skin -- primarily in the T-zone area of your face (nose, forehead and chin); that's where you have the highest concentration of oil glands. You can control it, but you can't change it -- the level of oil your skin produces is hardwired to your genes.
You know you have oily skin when:
- Your pores are clogged
- Your skin is usually the oiliest in the T zone area, which is across the forehead, down the nose and chin
- Your face looks shiny
- Your skin feels greasy
- Your makeup wears off within a few hours of application
- You are prone to pimples, blackheads and whiteheads
