Nutricosmetics is a type of supplement that claims to improve the health and appearance of skin, hair, and nails. They are typically taken orally in the form of capsules, tablets, or powders, and sometimes topically as creams or serums. The most common ingredients in nutricosmetics are vitamins, minerals, antioxidants, and omega-3 fatty acids. Some products also contain botanical extracts, such as green tea or resveratrol.
