The role of p.acnes bacteria in acne is well known. It inhabits your sebaceous glands and when overgrown, stimulates an immune system response which inflames and swells your pores. But up until about twenty years ago there remained some mystery, since p.acnes is also a perfectly normal member of human skin flora.
In the minds of many, clearing acne is the hardest challenge a human can ever face. It seems completely impossible; before you discover the real causes, nothing seems to work.
But the one goal which seems even harder to achieve is the healthy, natural, glowing skin tone. In your daily life, you probably have occasional sightings of “lucky” people with this skin.
Acne patients everywhere are in love with banana peels, apple cider vinegar and sea salt. Teenagers are fixated on questions like whether the natural salicylic acid in strawberry juice clears acne like the pharmaceutical version.
Human civilisation has evolved a lot since 4000 years ago. You don’t have to worry about disease, you don’t have to worry about the river Nile being invaded by frogs. You don’t get to battle enemy empires with swords anymore (unfortunately).
The question of why obese people have less acne has been asked for hundreds if not thousands of years.
Almost every teenager has wondered why their fat friend or classmate is completely free from acne. After all, obesity is the definition of bad health; people can’t comprehend why somebody so far away from the peak of fitness would have such clear skin. In all likelihood, medieval teenagers, Roman teenagers and even Ancient Greek teenagers were wondering the same thing.
