The Difference In Transepidermal Water Loss (TEWL) Values Between Sun-exposed and Non-sun-exposed Skin Among Male Medical Students

Abstract

Background: Transepidermal Water Loss (TEWL) is the amount of water released from the human body into the atmosphere through a diffusion process per unit of time. Changes in TEWL indicate impaired skin barrier function. Exposure to ultraviolet light for an extended period can cause photoaging, characterized by rough and dry skin (xerosis cutis). TEWL will increase significantly in the skin exposed to ultraviolet radiation. This study aims to determine the difference in the TEWL values among male medical students in the sun-exposed and non-sun-exposed skin areas.
