Yogurt and kefir are loaded with probiotics—beneficial bacteria that support a balanced gut and, in turn, healthier skin. These foods help reduce redness, inflammation, and acne by addressing the root causes of many skin problems that begin in the gut. Yogurt also possesses anti-aging and exfoliating properties, smoothing fine lines and imparting a healthy glow. For an added boost, yogurt can be applied directly to the skin for topical rejuvenation.
