In this study it was determined the capability to not produce allergic irritation of a stretch mark reducing cream (BEL-030509) through repetitive epidermal contact tests, after having undergone a preclinical study in which the result was the negative sensitivity in guinea pigs. 63 persons participated (n=63), they were selected after completing a survey that has the criteria of inclusion and exclusion approved by the Institutional Ethics in Research Committee (Comité Institucional de Ética en Investigación) of the National Institute of Health (Instituto Nacional de Salud) from Peru. We used three creams, the stretch mark reducing cream (BEL-030509) as experimental cream, petrolatum as negative control in face to the active ingredient of the experimental cream and the commercial cream Nivea as negative control in order to compare the grade of skin sensitivity in face to the experimental cream. These three cream were applied on the in selected persons in a patch with filter paper. We recorded the degree of irritation after removing the patch for each application. At the end of the study, it has been showed that the experimental cream did not cause any type of irritation (0%) compared to results obtained for petrolatum (0%) and for Nivea cream (0%). We conclude that the cream has no capacity to produce skin sensitivity after repetitive epidermal contact, showing that its use is safe at doses of 0.2 g per application.
