The numerical analysis of thermal processes proceeding in the skin tissue due to external heat flux is presented. Heat transfer in the skin tissue was assumed to be transient and one-dimensional. Thermo-physical parameters of successive skin layers are different, at the same time in subdomains of dermis and subcutaneous region the internal heating resulting from blood perfusion and metabolism is taken into account. The degree of the skin burn can be predicted on the basis of the so-called Henriques integrals. The paper deals with the sensitivity analysis of these integrals with respect to the thermophysical parameters. In numerical computations, the boundary element method has been used. In the final part of the paper, the results of computations are presented.
