Epidermal Layers Characterisation by Opto-Magnetic Spectroscopy Based on Digital Image of Skin

Abstract

According to the most literature data, the skin is usually observed as a simple structure with equivalent electrical model, which includes general properties of epidermis, basal membrane and dermis. In this paper, we analyzed the skin structure as a more complex system. Particularly we analyzed epidermis based on layers approach and its water organization in lipids ordered in sub-layers. Using opto-magnetic spectroscopy method, which is very sensitive to paramagnetic/diamagnetic properties of the tissue, we found out that nanowater structure ordering in lipids of epidermal layers play very important role in skin properties. We use bioimpedance as complementary and compatible method to opto-magnetic spectroscopy in skin characterization. In our investigation we found out the dierence of the skin properties of the people who are drinking two dierent type of water (Z and N). We observed the signicant dierence in middle part of stratum granulosum, where water-lipid sub-layers exists. These results indicate importance of water nanolayers presence in epidermis and type of drinking water reecting on human skin properties.
