Native to North America, blueberries are rich in essential nutrients including vitamins C, E, and K, as well as manganese, fiber, and riboflavin. Packed with antioxidants and phytochemicals, they help combat free radicals, supporting smoother, more youthful-looking skin. Blueberries also contain vitamin A, which may help regulate sebum production, making them beneficial for those with acne-prone skin.
