Skin is the main defense organ of the human body against external insults (ultraviolet radiations, infections by pathogenic microorganisms, and mechanical and chemical stress). The integrity and functions of the skin barrier are supported by an adequate supply of micronutrients, such as several vitamins. The purpose of this review was to analyze all vitamin-related skin problems.
The World Health Organization has estimated that more than 2 billion people worldwide experience deficiencies in the intake of essential vitamins and minerals; the percentage of adults all over the world using daily vitamin supplements, for treatment or prevention of chronic disease, has increased very rapidly in recent years. In this review, 65 studies have been selected in order to examine the role of the main vitamins and their derivatives involved in maintaining the well-being of the skin and their use as prophylactic and therapeutic agents in the management of skin disorders.
皮肤是人体抵御外界侵袭（紫外线辐射、病原微生物感染以及机械和化学应激）的主要防御器官。皮肤屏障的完整性和功能依赖于充足的微量营养素供应，如多种维生素。本综述旨在分析所有与维生素相关的皮肤问题。
世界卫生组织估计，全世界有超过 20 亿人存在必需维生素和矿物质摄入不足的问题；近年来，全世界成年人使用日常维生素补充剂来治疗或预防慢性病的比例增长非常迅速。在本综述中，选择了 65 项研究，以研究主要维生素及其衍生物在维持皮肤健康中的作用，以及将其作为预防和治疗皮肤疾病的手段。
