1. The law of cicatrization, of surface wounds may be expressed by an exponential formula in which the two coefficients may be determined.

2. A simple relation exists between these coefficients and the index, i, of cicatrization, previously established in function of the age of the patient and of the area of the wound.

3. The proposed equation with a simplified exponent, reduced to a single coefficient, expresses satisfactorily the phenomenon of contraction.
