Skin Hydration And Transepidermal Water Loss Measurement Using Vis/nir Spectroscopy And Feed-forward Backpropagation Neural Network

Skin hydration and transepidermal water loss (TEWL) are commonly measured using electrical method. However, electrical method can be affected by numerous factors such as the physical condition of the probe due to corrosion and oxidation, ambient temperature and humidity, and the underlying ions conc...
