Abstract

The skin's primary function is to act as a barrier against environmental insults, and its unique structure reflects this. The skin consists of two layers: the outer epidermis layer is highly cellular and provides a barrier function, and the inner dermal layer ensures strength and elasticity and provides nutritional support to the epidermis. Normal skin contains high concentrations of vitamin C, which supports important and well-known functions, stimulates collagen synthesis and aids in antioxidant protection against UV damage. This knowledge is often used as a rationale for adding vitamin C to topical applications, but the efficacy of such treatment, compared with optimizing dietary vitamin C intake, remains poorly understood. This review discusses the potential role of vitamin C in skin health and summarizes in vitro and in vivo research to date. We compare the efficacy of vitamin C nutritional intake versus topical application, identify areas where a lack of evidence limits our understanding of the potential benefits of vitamin C on skin health, and suggest which skin properties are most likely to benefit from increased vitamin C nutrition. that the effect of vitamin C on pigmentation has positive results, namely brightening the skin. several treatments for pigment disorders, in this case the management of melasm and lentigo senilis using vitamin C for systemic treatment.

Abstract

The basic concept of "external causes" or non-specific external causes refers to external factors that influence a phenomenon or event without pointing to a clear and defined cause. In various disciplines such as medicine, epidemiology, sociology, and economics, an understanding of non-specific external causes is essential to identify, analyze, and mitigate the impact of events that cannot be explained by internal or specific factors. These external causes can be the physical environment, socio-economic conditions, public policies, and unexpected natural events. This article aims to outline the basic concepts, analysis methodology, and implications of non-specific external causes in various study contexts. Through a deeper understanding of these external factors, it is hoped that more effective strategies can be obtained in managing risks and handling complex and multifaceted problems.
