Watermelon is also great for your skin because it contains vitamin A, a nutrient required for sebum production that keeps hair moisturized. Vitamin A is also necessary for the growth of all bodily tissues, including skin and hair. Watermelons are an excellent source of several vitamins: vitamin A, which helps maintain eye health and is an antioxidant; vitamin C, which helps strengthen immunity, heal wounds, prevent cell damage, promote healthy teeth and gums; and vitamin B6, which helps brain function and helps convert protein to energy.
