“Vegan face” is a term that has been coined to describe the clear, radiant complexion many people notice after switching to a vegan diet. This is believed to be due to the high intake of fruits, vegetables, and whole grains, which are rich in antioxidants that may help protect the skin from oxidative damage (14).
Moreover, eliminating dairy, which some research suggests may contribute to acne (2), can also lead to clearer skin for some people. That said, skin health is influenced by many factors, including genetics, environmental factors, and overall health.
