What stimulates melanin?
You get vitamin A from the food you eat, especially vegetables that contain beta carotene, such as carrots, sweet potatoes, spinach, and peas. Since vitamin A also functions as an antioxidant, some researchers believe this vitamin, more than any other, may be the key to melanin production.
