Physiologic analyzers designed to measure and evaluate all or most of the main characteristics of the skin, including elasticity, surface moisture and sebum, pigmentation and transepidermal water loss (TEWL). Some analyzers also include a microscope or video microscope to assess the skin conditions and/or ultrasound devices to assess the level of skin damage. The analyzer is usually microprocessor- or computer-controlled and contains appropriate software for data processing and digital recording. Skin physiologic analyzers are used to assess the skin characteristics during dermal, cosmetic, and/or occupational medicine studies. Dedicated measuring instruments intended only to measure one or a few characteristics of the skin (e.g., TEWL, elasticity, surface moisture or sebum) are also available.
