Skin health is not only significantly affected by ageing, but also by other lifestyle-related factors, such as sun exposure, exercise and eating habits, smoking or alcohol intake. It is known that the cutaneous tissue can exhibit visible signs of senescence, in the form of, for example, dull complexion, loss of firmness, or changes in pigmentation. Consumers attempt to improve skin health and appearance not only by cosmetic products, but also with the consumption of food supplements. Recently, there has been an increase in the amount of food supplements with claims that are related to skin and hair health. Nevertheless, the literature is still scarce in evidence of the efficacy of this type of products. Considering this scenario, we aim in this review to assemble studies and methodologies that are directed at the substantiation of the cutaneous health claims of food supplements. For example, we reviewed those that were indicative of antioxidant properties, improvement in pigmentation disorders, increased hydration or protection against the damages caused by ultraviolet radiation.
皮肤健康不仅受到衰老的显著影响，还受到其他与生活方式相关的因素的影响，如阳光暴露、运动和饮食习惯、吸烟或饮酒。众所周知，皮肤组织会出现衰老的明显迹象，例如肤色暗淡、失去紧致度或色素沉着变化。消费者不仅通过化妆品产品，还通过食用膳食补充剂来尝试改善皮肤健康和外观。最近，声称与皮肤和头发健康有关的膳食补充剂的数量有所增加。然而，关于这类产品功效的文献仍然很少。考虑到这种情况，我们旨在本次综述中汇集研究和方法学，以证实膳食补充剂对皮肤健康的宣称。例如，我们回顾了那些具有抗氧化特性、改善色素沉着紊乱、增加皮肤水分或防止紫外线辐射损伤的产品。
