It has EVERYTHING to do with what you EAT OR DRINK.
Food trigger certain hormones that cause acne.
Eat a really high lean protein diet, low carbs (good complex carbs are okay like oatmeal,veggies), and healthy fat (e.v. olive oil, fish oils, etc), AND your acne will reduce 75% in a few weeks.
Hormones are the main cause of acne true, but what most doctors fail to realize is how powerful certain foods are, and how the combination of certain foods can either make your face explode or put the acne in check.
Diet is everything.
But if you are a certain individual with persistent acne, check with your Derm for other options, But still - Even if he does perscribe you med, KEEP YOUR DIET ON POINT, and the effects of the meds will even be better.
Peace.
