Does protein powder cause acne?

Generally speaking, protein powder doesn't directly cause acne. 

However, acne can be a possible side effect if you have an allergy or intolerance to a specific food or ingredient, including whey protein or lactose. In this case, it can be assumed that most any dairy product would do the same thing as well. Sometimes, trial and error is the best method to figure out how your body will react. If whey does in fact cause skin issues for you, we offer 100% plant-based options as well. If you have additional concerns, we recommend consulting with your doctor or dermatologist.
