The market for cosmeceuticals continues with significant annual growth, but today consumers are more aware of nutritional products that contribute to both skin health and disease prevention. In the last 10 years, pharmacists, chemists, nutritionists, and physicians have been working together to develop new nutritional applications to satisfy people's needs and demands. As a recent result of convergence phenomenon between cosmetics and food industries, nutricosmetics is a blurry area unfamiliar to many consumers and sometimes even to foods and cosmetics experts. Characterized by oral supplementation of nutrients, nutricosmetics are also known as "beauty pills,""beauty from within," and even "oral cosmetics." The major claim is the antiaging effect, reducing wrinkles by fighting free radicals generated by solar radiation. Among the ingredients used in nutricosmetics, antioxidants represent the most crucial. The best-known antioxidants are carotenoids (beta-carotene, lycopene, lutein, zeaxanthin, and astaxanthin) and polyphenols (anthocyanidins, catechins, flavonoids, tannins, and procyanidins). This study presents an overview about the concept of nutricosmetics and gives us information about the difference between nutricosmetics, nutraceuticals, and cosmeceuticals. The article also discusses about carotenoids and polyphenols, two classes of ingredients often employed in such products.
功能性护肤品市场持续保持着显著的年增长率，但如今消费者更了解那些既能促进皮肤健康又能预防疾病的营养产品。在过去的 10 年中，药剂师、化学家、营养师和医生一直在共同努力，开发新的营养应用来满足人们的需求。由于化妆品和食品行业之间出现趋同现象，近年来出现了一个新的领域，即“营养美容品”，它对许多消费者来说是一个模糊的领域，有时甚至对食品和化妆品专家来说也是如此。营养美容品的特点是通过口服补充营养，也被称为“美容丸”、“内在美”，甚至是“口服化妆品”。其主要诉求是抗衰老作用，通过对抗由太阳辐射产生的自由基来减少皱纹。在营养美容品中使用的成分中，抗氧化剂是最关键的。最著名的抗氧化剂包括类胡萝卜素（β-胡萝卜素、番茄红素、叶黄素、玉米黄质和虾青素）和多酚（花青素、儿茶素、类黄酮、单宁和原花青素）。本文概述了营养美容品的概念，并介绍了营养美容品、营养保健品和功能性护肤品之间的区别。文章还讨论了类胡萝卜素和多酚这两类常用于此类产品的成分。
