BACKGROUND: Excessive sweating is a clinical condition that can be improved with type-A botulinum toxin (BTX-A).
OBJECTIVES: To evaluate and compare the largest diameter of sweating inhibition halo (SIH) of 5 different commercially available BTX-A, in five different doses, in a 6-month-long clinical evaluation.
METHODS: Twenty-five adult female volunteers were injected in the dorsal trunk area with both 100 units (100UI) and 500 units (500UI) BTX-A products, reconstituted in a ratio of 1:2.5 IU, respectively. Products were applied in five different concentrations (1:2.5U, 2:5U, 3:7.5U, 4:10U, and 5:12.5U). After 30, 60, 90, 120, 150, and 180 days, a starch-iodine test was performed to obtain the largest diameter of each SIH.
RESULTS: The higher the number of units used, the larger the SIH p < 0.05 for all BTX-A. However, Botox®, Botulift®, Dysport®, and Prosigne® have pretty likewise SIH along the study, with some few differences for some doses and months between one and another. However, Xeomin® is the BTX-A with the smallest SIH, in comparison with all others, in any dose and period.
CONCLUSIONS: Differences were observed among all brands of BTX-As, based on dose and time after injection. Xeomin® provides the smallest SIH in comparison with others BTX-A.
