Comparative Study of Intradermotherapy With Pressurized Injection System and Needles

Abstract

Intradermotherapy allows for treatment of different aesthetic conditions. Currently, it can be applied in its conventional form using needles or using the pressurized technique. The sample consisted of 35 women with adiposity located in the abdominal region. The volunteers were randomly assigned to 3 subgroups: G1 (n = 12) who were subject to the pressurized technique and the conventional technique with needles using only saline substance, with 6 volunteers in each application mode; G2 (n = 9), who received pressurized application using Concept Ti Liporedutor (lipolytic substance); and G3 (n = 14), who were treated with the needle injection technique, with the same substance used in G2. All groups received 4 treatment sessions with 2-week intervals between them. The analysis of the fat layer conducted 90 days after the initial application demonstrated a significant reduction in measurements in the treated groups, and also when compared with the control group, both for ultrasound, perimetry, and plicometry (only right side) data. Despite the effectiveness of the 2 application techniques, the pressurized method showed superior results. Hyperemia and skin marks were among the adverse reactions reported by the groups, but they showed quick resolution. It is noteworthy that most of the volunteers in the treated groups evaluated the results positively and were satisfied with the treatment. The intradermotherapy protocol with lipolytic substance significantly reduced the fat layer, with more evident results when using the pressurized application method.
