The epidermis has been properly prepared one hour
before measurements of the hydration degree. The experiment
started from cleaning the tissue and separating the
tissues from the bones. Then, epidermis was shaved and
cut into pieces with dimensions of 4 cm × 5 cm and 2 cm
× 3 cm. To remove excess moisture from its layer, the skin
was placed in a thermal dryer SUSLAB-PLE-419 (Adverti)
with temperature control. It underwent four sessions, each
lasting 10 min at 60°C. Then, the model was disinfected
with a solution of 2% salicylic acid.
