The difference between someone who has acne and someone who doesn't is that the person who doesn't has a liver (along with other filter organs) that is clearing their blood from any excess blood toxins and hormones.

The recipe for acne is someone with excess sebum, but whose sebum is mixing with blood and lymph fluid toxins. This causes the perfect breeding ground for bacteria to grow and flourish. Bacteria do not cause acne. Instead, the unhealthy environment in and on your skin invites them. This is why for years and years you can try to get rid of acne and it just keeps coming back over and over and over. The host organ (your skin) has remained an unhealthy environment, which is hospitable to bacteria.
