A study has discovered that the naturally occurring hormones in cow’s milk may have a connection to acne. They may signal an over production of testosterone-like hormones in the body. Because of this, the skin produces more oil, which results to break outs. Even the iodine given to cows to avoid infections ends up in the milk they produce and when we drink their milk, it intensifies acne. If you are using anti-acne beauty products for at least a month and using strong prescription treatments and still no go, maybe you can think about removing dairy products from your diet?
