Acne is a multifactorial disease of the oil glands influenced by hormones. It is not a sign of a bad liver, weak immune system, inferior genetics, food allergy, emotional problems, gut disturbance or even hormonal imbalance.
Just because you have acne does not mean you're sick - more than likely you're perfectly healthy as the next person, You just have bad skin.
Don't fret or panic that you have some horrible underlying health problem. It's really unlikely there's anything wrong with you. Remember some people just have acne, it's just apart of your genes.
