The Truth About How Dairy Is Affecting Your Skin

According to Dr. Lipman, dairy is a trigger for skin problems, including acne.

"All dairy, even if from grass-fed organic cows, comes from lactating cows," he explained. "It's therefore full of hormones from the cow, which can translate into hormonal acne in humans — particularly because it boosts male hormones, which are linked to acne."

He went on to reveal that a 2009 review of 21 studies found that cow's milk increased both the number of people who got acne and its severity.
