Skin potential level (SPL) of the human is used in different areas of researches (C. Nishimura, J. Nagumo, 1985, Y. Gorgo 1986). SPL depends of ion-flux end mitochondrial activity (M. Denda et al, 2002). But in too time it is very poorly known about an origin of SPL. We studied SPL in various non-uniform on the morphology and methabolic level sites of a skin (haematomas, traces from stings of insects, melanocytic nevus, common warts (verruca vulgaris))with intact epidermis. In research took part 20 volunteers of both sexes in the age of 18–21 years. One of electrodes (active) disposed on a researched site of a skin with non-uniforms, another (indiferent) disposed on distance of 2 cm on an adjacent site of skin without specific changes. SPL registered thus changed within the limits of 2–8 mV, while at an arrangement of both electrodes on distance of 2 cm on a normal sites of a skin, did not exceed 2 mV. Was revealed, that in the non-uniform skin sites, in which there are active processes (inflammation, regeneration - haematomas, traces from stings of insects, or pathological growth - common warts) SPL is by more positive in comparison with adjacent skin sites. And on the contrary, in sites of a skin with decresed metabilic level (V. Siskind et al 2002) (the old scars, nevuses) SPL are much more negative, than in adjacent zones.
