What is the Origin of Environmental Dermatology?

This is a recognized sub-specialty of clinical dermatology, combining "environmental" (external influences) with "dermatology" (the study of the skin). The discipline has expanded its focus from simple contact reactions to include the systemic effects of environmental exposure. The recognition of the skin's capacity for local steroidogenesis and its dense network of hormone receptors cemented its relevance to endocrinology.

What is the Mechanism of Environmental Dermatology?

Environmental stressors like UV exposure or chemical pollutants can induce oxidative stress and chronic inflammation within the dermal and epidermal layers. This inflammation can disrupt the skin's barrier function and interfere with local cutaneous hormone metabolism, including the synthesis of vitamin D and the local action of sex steroids. The resulting inflammatory cytokines can also enter systemic circulation, subtly modulating the central Hypothalamic-Pituitary-Adrenal axis and contributing to systemic hormonal dysregulation.

Environmental Dermatology

Meaning

Environmental Dermatology is the specialized field that investigates the profound and complex interactions between external environmental factors and the structure, function, and pathology of the skin. These factors include air pollution, UV radiation, climate change, and exposure to various chemical xenobiotics. In the context of hormonal health, this discipline recognizes the skin as a major endocrine target and interface organ whose health reflects and influences internal hormonal balance. The skin is a crucial sensor and effector of environmental stress.
