I've had adult acne (acne vulgaris) on-and-off for two decades, and though not life-threatening, it can be most unattractive. When I stopped eating non-vegan desserts, and finally ditched the pizza and switched to a raw, vegan energy bar, an interesting thing occurred: my acne disappeared. I would never have guessed that I ate enough dairy products to have gotten significant doses of hormones, butterfat, iodine, or milk sugars, but the only thing I changed was my diet, and my skin cleared within weeks.
