In one embodiment, the otropic isotropic zones may be within a twenty percent efficient epidermal elasticity of ten percent of the patient's epidermal coefficient or within five percent by efficient elasticity of the epidermis of the ordinating coefficients. Orthropic elasticity with the elasticity coefficients of the tissue site can minimize the tension or protect the tension and promote the cic to minimize the pathological scarring. It should be pointed out that the isotropic zones 324, 3 are arranged in such a way that they are annular in a plan view and the isotropic areas 6 may or may not be arranged in such a manner that otropics 324, 326 are concentric with each other. Since the isotropic zones 324, 326 are similarly shown to be similar thicknesses, it can be seen that the isotropic zones 324, 326 are substantially parallel to each other, as isotropic 324, 326 can be seen to have any difference in relation to each other.
